MINUTES OF THE 22nd MEETING OF WESTERN REGIONAL POWER COMMITTEE HELD ON 26th FEBRUARY 2013 AT GANDHINAGAR

The 22nd WRPC meeting was held on 26th February 2013 at Gandhinagar and

it was preceded by the TCC meeting on the 25th February 2013 at Gandhinagar. The

meeting was hosted by GETCO.

The list of participants is enclosed at Annex-I

During the inaugural session Shri S.D.Taksande, Member Secretary I/c,

WRPC welcomed Shri Saurabhbhai Patel, Hon’ble Minister of Energy and Petro-

chemicals Gujarat state who had kindly consented to address the meeting. He

welcomed Shri D.J.Pandian, Principal Secretary, Govt of Gujarat, Shri Arvind Singh,

CMD, MSETCL who would be chairing the WRPC meeting and Shri U.G.Zalte,

Director, MSETCL and TCC Chairman. He informed that during the recent grid

disturbances of July 2012 WR survived, because of the concerted efforts made by

the constituents of WR. He requested Shri Saurabhbhai Patel, Hon’ble Minister of

Energy and Petro-chemicals Gujarat state to share his valuable views on power

sector to delegates.

Shri Saurabhbhai Patel, Hon’ble Minister of Energy and Petro-chemicals

Gujarat state welcomed all the delegates. He informed that energy is a very

important infrastructural input which is basic to any development. In spite of the

increase in generation, still there are many areas in the energy sector that require

immediate attention and there is a need to change the mindsets. There has to be

adequate transmission corridors. Policy decisions are required to be taken which

shall result in optimal cost. There was also a need to examine subsidies across

various sectors. He informed that solar power development in Gujarat has come up

in a big way. In the past few years the power sector has stabilized the frequency,

computerized many areas, which are good signs of developments. Finally he wished

that the delegates shall flag such decisions at the highest levels so that suitable

policies are framed to improve overall Power Sector efficiency.

Shri Arvind Singh, CMD, MSETCL on behalf of Shri Ajay Mehta, CMD

MSEDCL & Chairperson , WRPC welcomed Shri Saurabhbhai Patel, Hon’ble

Minister of Energy and Petro-chemicals Gujarat state, Shri D.J.Pandian, Principal


Secretary , Shri Raj Gopalan, MD GUVNL and other delegates from various power

sector organizations attending the WRPC meeting.

He thanked Shri S.K.Negi, Managing Director GETCO, for consenting to host this

meeting of WRPC and making excellent arrangements for the meeting and for

comfortable stay of the members attending the TCC and WRPC meetings.

He then presented the performance of WR power system during the period.

He informed the delegates that during the period October 2012 to January 2013 the

regional demand were in the range of 40000 MW to 41500 MW. The corresponding

peak shortfall was in the range of 1000 MW to 3000 MW which is equivalent to 2 %

10.00%. The energy requirement during the said period is in the range of 24000 MUs

to 26500 MUs. The energy deficit observed was of the order of 35 MUs per day to 45

MUs per day which is equivalent to 3.0% to 4.5 % respectively. The percentage time

frequency was in permissible range of 49.7 to 50.2 Hz was 81.00% to 91.0% during

this period.

In the current year 2012-13 since April 2012 an additional generation capacity of the

order of 6970 MW has been commissioned in the region. Additional transmission

capacity of EHV 220 kV, 400 kV and 765 kV intrastate and interstate transmission

network of 2224.26 Ckt Km has been commissioned in the region since April 2012.

As the status on various schemes is being monitored by the Committees in quarterly

Transmission Review meetings, it is observed that in view of the coming up of

additional generation capacity, adequate transmission capacity in the region has

been commissioned at EHV level by CTU /PGCIL and the other private agencies

under the IPTC route are also in the process of nearing completion of the schemes.

It is therefore necessary that the downwards EHV system planned for getting

connected with the CTU network is completed expeditiously in line with the schedule

of progress.

During the period November 2012 to January 2013 the voltages at different

important 400 kV substations are in the range of 387 kV to 442 kV and 765 kV sub-

station are in the range of 735 kV to 806 kV. For the voltage control at various

important nodes(S/S) in WR, 34th Standing committee meeting held on 09th May,

2012 on power system planning of WR recommended for installation of reactors at

seventeen locations. (in addition to 10 reactors of 33rd SCM ).


Shri D.J.Pandian, Principal Secretary, Govt of Gujarat welcomed all the

dignitaries on the dias and delegates of the meeting. He expressed pleasure in

working with the Hon’ble Minister Shri Saurabhbhai Patel. In this period Gujarat has

happily progressed in terms of generation, both renewable and non–renewable

energy sources. The need is to address transmission and distribution issues. He

thanked all the constituents of WR for disciplined grid operation which is the most

important requirement for operation of power sector. A rising challenge is in terms of

wind and solar energy because wind in particular has difficulties in forecasting and

control. He hoped that the deliberations would be useful in resolving various issues

in western region power sector.

After the inaugural session, the WRPC meeting agenda items were taken up

for discussion by Member Secretary, WRPC.

ITEM No.1: CONFIRMATION OF THE MINUTES OF THE 21st MEETING OF WRP COMMITTEE

Member Secretary I/c, WRPC stated that minutes of 21st meeting of WRP Committee

held on 09.11.2012 at Raipur were forwarded to the members vide letter No.

WRPC/21ST WRPC Mtg./AS/2012/ 11757 dated 13.12.2012.

GM, WRLDC vide letter dated 24.01.2013 have sent their comments on item 19 of

minutes of 21st WRPC meeting (enclosed at Annexure-1) and requested for

correction in the total numbers of SEM/DCDS.

“The summary of requirement of SEMs and DCDS up to 2014 is as follows:

Items No. of Main meters

No. of stand-by/Check meters

Total No of SEMs/DCDs

Total No. of SEMs required 268 71 339 Spares @20% 68 Net Total 407 Total No. of DCDs required 26 Spares @20% 5 Net Total 31 TYPE OF METER Model-A


Corrections sought by WRLDC was accepted and WRP Committee confirmed the minutes with the above corrections.

ITEM NO. 2: STATUS OF IMPLEMENTATION IN WR ON RECOMMENDATIONS

OF REPORT ON GRID DISTURBANCE ON 30TH AND 31ST JULY 2012:

Member Secretary I/c, WRPC informed that the current Status of implementation in

WR on Recommendations of Report on Grid disturbance on 30th and 31st July 2012

as on 10.01.2013 is given at Annexure-2. He further informed the members to

apprise of the current status with respect to those recommendations that come

within the scope of RPC.

TCC discussed the above recommendations. Shri S.K.Negi, MD, GETCO informed

that GETCO had carried out the protection audit and also complied with the

recommendations of the audit, which were carried out by M/s Voltamp after tender

process. He informed that the audit was very useful to GETCO system.

Member Secretary I/c, WRPC requested constituents to update the status regularly

since it is monitored at high level on monthly basis. Regarding Zone 3 settings, he

informed the members that latest Transmission Planning Criteria was issued by the

CEA and the same had some recommendations on Zone 3 settings, to address the

issue of tripping of lines in Zone-3 due to load encroachment/power swing.

Regarding WAMS, PGCIL intimated that PMUs under URTDSM were being

procured through NIT in March 2013. IIT-B is associated with Analytics

development. GETCO informed that they are also installing 25 PMUs and with IIT-B

for analytics for On line security assessment, oscillations modes analysis, hybrid

state estimator, voltage stability. WRLDC informed that they have installed 4 PMUs

and 7 more are being installed in WR. WRLDC have in house developed analytics

for FFT, prony analysis, wavelet transforms.

Regarding review of UI mechanism, GETCO informed that 150 MW or 12 % of

schedule overdrawl in the UI mechanism was too strict a band for controlling the

drawls in line with the schedule, particularly when non conventional sources like

wind energy are present, as there is a high degree of uncertainty with the wind


generation. This causes problems in load dispatching. They requested WRLDC to

widen the band by taking the issue with the Hon’ble Commission CERC.

The present status of the recommendations is given at Annex 2.1.

WRPC/TCC noted.

ITEM NO. 3: OTHER RECOMMENDATIONS (OF ZALTE COMMITTEE)

A. Defense Mechanism for high frequency

BackGround: Member Secretary WRPC, informed that after detailed studies by

WRLDC following units were identified for automatic tripping at high frequency (51.5

Hz) to help arresting the rise of frequency in case of islanding of WR from rest of

NEW grid :

1. KSTPS-7 (500 MW) 2.VSTPS-7 ( 500 MW) 3. CGPL-10 (830 MW)

During the 21st TCC meeting held on 8.11.2012, Member Secretary I/c WRPC had

informed that in the PCM meeting held in 7th September 2012 in Pune, different

utilities are adopting different high frequency trip settings with different time delays

and were no identified units to trip and random tripping takes place. He had informed

that the intention of the Zalte committee was to identify three units, checked by

simulation studies, which would definitely trip at 51.5 Hz. During the 21st WRPC

meeting, ED(Commercial), NTPC WR intimated that the matter regarding tripping of

NTPC units Korba-7 and VSTPS-7 was discussed will be NTPC Corporate and in the

opinion of NTPC high frequency situation does not warrant a tripping of there units.

He informed that the machine will be fully unloaded by governor action and if further

discussions are required the same can be discussed in the 29th November 2012

meeting.

In the meeting held on 29.11.2012, NTPC expressed concern that in the grid of

40,000 MW, identification of units should be done equitably. Only NTPC units should

not be singled out for the said issue.

NTPC representative made following points:

i. Rise in frequency is not a situation which warrants drastic action to trip units

to reduce generation, as it cannot cause a collapse of the power system,

unlike the situation of low frequency. High frequency can be easily controlled


by controlling the generation. From the system point of view higher than

nominal frequency is not considered dangerous/harmful to the system and

system equipments.

ii. At frequency varying from 51.0-51.5Hz, all thermal machines in the system

(except the older mechanically governed machines), including CCGT units will

start unloading as per the droop characteristics. Assuming a governor droop

of 5%, this would result in reduction of 20% of the generation capacity in

service, for a frequency rise of 0.5Hz, above this threshold. This unloading

feature can neither be offset beyond 51.5Hz nor can it be prevented, being a

safety feature.

iii. CCGT units at Jhanor start unloading at 51.2Hz and are wired to trip at

51.7Hz. Kawas CCGT units start unloading at 51.2Hz as per its governor

droop.

iv. In the event of such a frequency rise it is likely that some generators trip

during the re-adjustment of their process, inadvertently. During the said

disturbance also such tripping had taken place. If the total generation

available after such intended and inadvertent unit outages fall short of the

load, the system will be facing a far more disastrous frequency decline

situation.

In reply, Member Secretary I/c, WRPC intimated that a quick and adequate response

in generation dropping was required under such disturbances which was a rare

situation. The tripping of above units have been arrived by giving due considerations

to the above facts and system studies carried out by WRLDC. Also it may be noted

that the above trippings have been envisaged after resorting to all the measures

required to be undertaken under such circumstances by WRLDC in the real time grid

management. Therefore NTPC should not feel that the above units have been

singled out.

In view of system security, NTPC may agree to the above recommendations of

WRPC and implement the tripping of above generators at high frequency of 51.5 Hz.

Discussions: During the TCC, NTPC informed that they have reviewed the stand

and NTPC in principle accepts the proposal with the following conditions:


i) In view of the addition of new capacities and change in dynamic flows

in NEW grid, the above proposal shall not be on a permanent basis and

reviewed in a period of one year.

ii) In line with the scheduling clauses under IEGC, UI of the units shall be

immediately suspended from the time block in which the tripping occurred due

to the operation of the high frequency protection .Schedule Generation shall be

equal to Actual generation from the time command is received till as advised by

RLDC so that the stations do not suffer commercially while trying to enhance

the grid security.

iii) DC of the station prior to tripping shall continue to be Deemed DC till

the revival of the unit in respective station.

iv) To avoid tripping in transient conditions/spurious frequency rise to 51.5

Hz, if any, a suitable tripping logic like the mechanism of df/dt or some time

delay logic as deemed fit for tripping of the above units may be considered for

incorporation. The committee decision for the same shall be final and agreed

upon by NTPC.

Member Secretary I/c WRPC, stated that with WRPC agrees for the high

frequency tripping with the above conditions, the defense mechanism of high

frequency tripping of units can now be incorporated by NTPC.

WRPC noted as above.

B. SPS of 400 kV Bina-Gwalior lines:

Background: Member Secretary I/c WRPC informed that following Units in WR

were to be considered for backing down to the tune of 500 MW in the event of

tripping of Agra-Gwalior lines and Bina-Gwalior lines :

B. ) Korba, Sipat, Vindhyachal STPS to control power flow towards ER

ii) CGPL & SSP* to control power flow in Zerda-Bhinmal-Kankroli lines

iii) JP Bina to control power flow in Bina-Mehgaon-Gwalior lines &

iv) ISP* to control power flow in Badod-Kota-Modak lines


*Since SSP and ISP are hydro units and may not be always available, Committee

recommended backing down of 500 MW at Korba, Sipat, Vindhyachal, CGPL and JP

Bina.

During TCC meeting held on 8.11.2012 GM, NTPC stated that NTPC units are

participating in RGMO. He stated that CERC norms require generation backing down

from short term, then medium term and long term units. These units are not

transacting with any utility in NR. Hence backing down of generation on SPS is not

required. Members felt that, the above arguments are valid during the steady state

conditions. Also the scheduling is done based on the assessment of availability of

transmission corridors by considering designed contingencies stipulated in IEGC.

However in real time, as seen during the GDs, there is hardly any time for manual

intervention for taking corrective actions. The actions suggested above by NTPC

may require considerable time. Further the electrical flows follow law of physics and

curtailment of schedules may not be a solution for maintaining the system stable

under tripping of these lines, since this may lead to rush of power in the other

corridors and may lead to unnecessary tripping other elements in WR system.

Discussion: In view of the above, Member Secretary WRPC once again requested

NTPC to participate in the above scheme in the TCC meeting.

ED(WR-I) NTPC stated that, NTPC in principle, is in agreement with the scheme

however the schemes should be reviewed at yearly intervals. The control signals

shall be made available at NTPC stations. He further requested that, whenever the

scheme operates Actual Generation (AG) shall be made equal to Scheduled

Generation( SG) during the period the generation was backed down.

WRLDC informed that under IEGC 6.5.17 clause, if the operation of the scheme can

be treated as creating a transmission corridor constraint on Inter Regional links, AG

can be made equal to SG.

GETCO representative stated that the STOA should be curtailed first under such

circumstances and then the AG shall be treated as SG.

MD GETCO suggested that in case the flow on 400kV Bina-Gwalior line exceeds a

preset overload, an alarm should be set and necessary control actions shall start so

that tripping can be avoided.


WRP Committee accepted the above suggestions and requested PGCIL to provide tele-metering and control signals at the generating stations.

ITEM NO 4: IMPLEMENTATION OF DEMAND MANAGEMENT(IEGC 5.4), GRID SECURITY EXPERT SYSTEM AND DEMAND ESTIMATION: Member Secretary I/c, WRPC informed that a petition was filed by PGCIL with the

Hon’ble Commission CERC (Petition 265/MP/2012) seeking Commission’s approval

for implementation of Grid Security Expert System by PGCIL in all the five regions.

As stated in Items no 3 & 4 of the ROP dated 10th January 2013 that the RPCs of all

five regions would also take up the issue of “Implementation of Automatic Demand

Management Scheme at SLDC/DISCOM level” (ADMS) and “Implementation of Grid

Security Expert Systems” (GSES) as an agenda item within one month from the date

of issue of this ROP and file their decisions within one week thereafter, after serving

copies thereof on all the constituents of the respective RPC.

He informed that both the issues were discussed in the Protection Committee and

Operation Co-ordination Committee levels. He also informed that the matter was

under discussion in other RPCs as well. The brief description of the above and

relevant IEGC clauses and other information is given in Annex 4.1

The outcome of discussions was informed to the TCC. The TCC after discussion

recommended the following:

1) The implementation of GSES and ADMS were agreeable in principle.

2) As the Automatic Demand Management Scheme is a subset/ part of GSES

and therefore it was recommended that the same will be implemented along with

GSES.

3) Settings of frequency based defense mechanisms and quantum of load

shedding etc., needs to be co-ordinated with other regions of the NEW Grid.

4) Manual load shedding, Automatic load shedding by demand management and

load shedding under AUFLS and df/dt of GSES requires to be co-ordinated to avoid

overlap and have clear distinction between manual actions and automatic control

actions.

5) Logic, technology, communication facilities, funding and controlling agencies

needs to be addressed.

6) Possibility of including WAMS data in the above schemes requires to be

explored.


The TCC recommended that to discuss the above issue a group comprising of

representatives of concerned utilities at appropriate levels shall require to be formed

and the group may place its recommendations to the WRPC for its vetting and

approval.

WRPC accepted the recommendations of TCC and Chairperson requested Member Secretary I/c to communicate to the Hon’ble Commission CERC the decision of WRPC and put up recommendations of group thus formulated to next WRPC meeting. ITEM No. 5: PERFORMANCE OF WR GRID DURING OCTOBER 2012 TO

JANUARY 2013

Member Secretary I/c requested GM, WRLDC to present the highlights system

performance during October 2012 to January 2013. GM, WRLDC presented the

highlights of the system and the same is as follows.

5.1 SYSTEM PERFORMANCE Frequency: During months of October, November, December 2012 & January 2013, the grid

operated in the IEGC frequency range of 49.7 Hz to 50.2 Hz for 90.39 %, 85.83 %,

84.10 % and 80.95 % of time respectively. The frequencies below 49.7 Hz were from

1.79 % to 4.63 % of time during October 2012 to January 2013. In higher frequency

regime, system frequency remained above 50.20 Hz for 6.28 %, 12.38 %, 11.51 %

and 14.42 % of time respectively in October, November, December 2012 & January

2013. The monthly average frequency was 49.98 Hz in October 2012, 50.02 Hz in

November 2012, 50.00 Hz in December 2012 and 50.01 Hz in January 2013.

The instantaneous frequency didn’t touched 48.8 Hz during October, November,

December 2012 & January 2013. The detail of frequency profile for the months of

October 2012 to January 2013 is placed at Annexure-5.1(a). Significant Under Drawal a F>50Hz: Madhya Pradesh, Gujarat and Maharashtra

had under drawn during the period 7th Jan’13 o 13th Jan’13 at frequency greater

than 50Hz. which further pushed the frequency up.

Demand : The maximum unrestricted demand of Western Region was 41479 MW, 40302 MW,

41131 MW and 41026 MW in October, November, December 2012 & January 2013

respectively, as compared to 43409 MW, 43839 MW, 43737 MW and 41753 MW

during the same months last year respectively. The region faced capacity shortage

in the range of 590 MW to 2315 MW (peak deficit of 1.42 to 5.64%) respectively

during these months. The details of unrestricted peak demand, demand met and

energy requirement and availability are as furnished at Annexure-5.1 (b). 5.2 Voltage Profile 5.2.1 Overall voltage profile had been satisfactory during the period under review.

However, instances of low and high voltages beyond the IEGC specified operating

range were observed at some of the EHV sub-stations in the region. Higher voltages

in the range of 421 kV to 442 kV were noted at Indore, Itarsi, Karad, Dhule, Kasor,

Bhilai, Jetpur, Bina, Gwalior, Nagda and Khandwa substations. Also the 765 kV

Seoni Substation touched to 806 kV on 13th December, 2012. To contain high

voltages WRLDC resorted to opening of lightly loaded EHV lines on certain days.


The detail of voltages at important 400 kV and 765 kV sub-stations for the months

October 2012 to January 2013 is placed at Annexure- 5.2. The voltage duration curve at Bhadravathi and Raipur shows that voltage was

above 420kV for most of the period during Oct’12 to Jan’13. At Bhadravathi voltage

was above 420kV for 99%,99%,83% and 96% for Oct’12,Nov’12, Dec’12 & Jan’13

respectively and at Raipur 100%,100%,89% and 100% for Oct’12,Nov’12,Dec’12 &

Jan’13 respectively

5.2.1 Concern was noted of the excessive voltages present in the grid and control actions were requested to be initiated at around 420 kV itself.

5.3 AUFLS Performance. The month-wise details relating to performance of AUFLS scheme in Western

Region during the period October 2012 to January 2013 in terms of quantum of load

relief obtained and number of occasions the UFR operated is at Annexure-5.3. Frequency didn’t touched 48.8 Hz during the period October 2012 to January 2013

and as such there were no UFR operation in WR grid.

5.5 Generation Constraints : The following are the generation constraints in WR Generation constraints ( as on 21st Feb’13) due to various reasons like fuel shortage

and partial outage amounts to 5032MW , while due o less schedule amounts to

4754MW mainly at gas based power stations. Additionaly around 1200MW is under

planned & forced outages.

5.6.a Load Crash in NR in the night hours of 17th/18th January, 2013.

Due to inclement weather in Northern Region in the night hours of 17th/18th January,

2013, about 9000MW load crashed in the Northern region. About 2000-2300MW

change of power flow took place on West to North corridor. Even about 2000MW

demand was observed to be less in the Western Region compared to the previous

night. The load crash started at about 22hrs of 17-01-2013. High frequency

(maximum:50.83Hz) and High voltages prevailed throughout the night hours and

about 12 lines of 400KV were either opened or tripped in a span of 1hour 20Minutes,

i.e., between 22hrs-23:20hrs. Power to the tune of 1100MW was wheeled back on

400kV Kankroli-Bhinmal-Kansari , 220kV Kota/Modak- Badod paths vis a vis WR to

NR power order set point of 1250MW on Mundra- Mohindragarh HVDC line. Loading

on 400kV Itarsi-Khandwa-II, 400kV Sugen-Vapi and 400kV Chorania-Kasor were

observed to be on raising trend in the early hours of 18th January, 2013. No

ATC/TTC was violated due to import of power. It was an unique situation where

either generation could not be increased further or generation could not be backed

down further. Power ramping to the tune of 100MW/185MW was observed on

HVDC, Bhadrawati towards Southern region on two occasions due to frequency

controller action at HVDC, Bhadrawati. Oscillations of different low frequency modes


with poor damping were observed due to stress in the system. WR system is

characterized by skewed/unusual dispatch conditions, high voltage, high frequency

and over drawal by Gujarat ( due to backing down to technical minimum and

withdrawal of high cost generation.) leading to critical line loadings. The lessons to

be learnt from this event are important.

Tripping of following elements would have had been a security threat to western

region:-

• 400kV Itarsi-Khandwa-II

• 400kV Seoni-Khandwa –II

• Even One cirguit of 400kV Parli-Lonikhand D/C

• Even either circuit of 400kV Kankroli-Kansari or 400kV Bhinmal-Kansari

• Even one pole of HVDC, Bhadrawati

• Even one pole of Talcher-Kolar

5.6.b Load Crash in NR in the night hours of 4th/5th February, 2013.

1. Due to inclement weather in Northern Region in the night hours of 4th/5th

February, 2013, about 9500MW load crashed in the Northern region.

About 900MW change of power flow took place on West to North corridor

compared to the previous day. Even about 3000MW load reduced in

Madhya Pradesh due to inclement weather. The load crash started at

about 20hrs of 04-02-2013. High frequency (maximum:50.71Hz) and High

voltages prevailed throughout the night hours .The following aspects are to

be noted from these two situations of heavy load crash in NR

a) Inordinate opening of lines on HV can cause problems.

b) Itarsi - Khandwa / Seoni-Kandwa line trippings could cause weakening

of corridor between Gujarat & MP vs. Maharashtra and may cause

oscillations.

c) Gujarat b/d their costly generation and drawing from the grid which is

causing critical line loadings. We must know for each State import &

export ATC to do such cost optimization.


d) Possibility of grid separation WR tripping of Bina-Gwalior-Agra on HV

or Zerda-Kankroli or Kota/-Modak-Badod-Ujjain ( if one line trips, the

other may also collapse) can lead to a disturbance.

e) Generators should absorb Vars to contain HV problem.

f) Opening of lines for different dispatch scenerios (on HV) would be

different and load despatchers in real time cannot decide easily.

g) Load Crash should not be caused by inordiant, tripping of distribution

feeders.

h) Situational awareness ( whether LDs know that there is an emergency

to understand extreme conditions is required through certain indices.

i) On 4th / 5th February, the following trippings would have caused a

disturbance

(i) At 2040 hrs. all lines emanating from ISP tripped on O/V, one

unit was running at ISP.

(ii) Dehgam – Vadavi D/C tripped on Y-ph fault, resulted in more

loading of Adani-Sami-Dehgam.

(iii) Tripping of bipole of Mundra-Mohindragarh bipole-Adani-7&9

tripped.

j) IPPs Jaigarh & JPL generation full while cheaper generation b/d

.Proper load forecast and weather forecast could have reduced STOA

rather resorting to cheaper generation reduction during real time.

5.7 Evaluation of a-eberle collapse prediction relay----LFO Comparative analysis using PMU data & Dynamic Power System Stability Monitoring System- WRLDC Experience

As discussed in the 21st WRPC meeting that, as a pilot project WRLDC has installed

one M/s. a-eberle Dynamic Power System Stability Monitoring System Relay/

collapse prediction relay at 400kV Boisar Substation on 17.10.2012. WRLDc’s

experiences, case studies and recommendations on PMU and Dynamic Power

System Stability Monitoring System Relay are shared below:-

The collapse prediction relay with inbuilt applications can process the data locally

and decision making available locally and collapse prediction relay can record

modes in the range of 0.005 to 98Hz.


In order to visualise wide range ( 0.005 to 98Hz) of modes present in the system,

local analytical engines along with high sampling rate based devices are very much

required to understand the Dynamics of the System with help of Global visualisation

tools. Further, the application of Synchrophasor technology using PMUs and these

relay based Dynamic Power System Stability Monitoring System would complement

each other. Both the systems would alert about the state of present system and

degree of stability, damping etc. The a-eberle has inbuilt applications for oscillation

monitoring, voltage collapse, stability exponents etc. Further the a-eberle relay uses

all the sampled data and also maintains history of events such as mode history.

WRLDC is in the process of validating the analytical results of local analytical

engines at site and global engines at control centre. WRLDC is already running

various applications including modal analysis based on global PMU data.

Results from both collapse prediction relay and PMU data were analysed and

compared. Even the load crash event on 17th & 18th Jan’13 and 4th & 5th Feb’13 were

analysed with both the systems. Both WAMs and a-eberle relay gave identical and

consistent results. The analysis of any event from to different systems would

facilitate grid operators better early warning signals on stability aspects for taking

corrective actions only when both the system alert the operator.

WRP Committee noted. ITEM No.6: ANTICIPATED POWER SUPPLY POSITION IN WESTERN

REGION FOR THE PERIOD FROM MARCH 2013 TO MAY 2013

Member Secretary I/c, WRPC informed that the anticipated power supply position in

the region for the period from March 2013 to May 2013 is given at Annexure-6. The

period under consideration is summer season. The anticipated regional demand is

likely to vary between 40000 MW to 44000 MW and the capacity shortage will be

around 7.00 %. In terms of energy, the unrestricted requirement is expected to

range from 26500 MUs to 29000 MUs with regional energy deficit of the order of 5.0

% to 6.0 %. The anticipated Peak demand shortage of 120 to 270 MW in Gujarat, 60

to 130 MW in Chhattisgarh, 1075 to 1350 MW in Maharashtra, 800 to 900 MW in

Madhya Pradesh, 30 to 40 MW in Goa, 15 to 25 MW in DD & 20 MW to 30 MW in

DNH is likely to prevail.


WRLDC has arrived the anticipated Summer Position of 2013 from the estimated

demand projected by constituents . The details are given below. Maharashtra will

have highest anticipate deficit of 2830MW , followed by Madhya Pradesh (700MW)

and Chhattisgarh (450MW). All the constituents are advised to take necessary steps

to meet the shortage.

WRP Committee noted. ITEM No 7: ANNUAL LOAD GENERATION BALANCE FOR THE YEAR 2013-14

Member Secretary I/c, WRPC informed that a meeting of LGBR group was held on 29th

November, 2012 at WRLDC, Mumbai. The group finalized the tentative outage

Program of major thermal units for the Year 2013-14. The same was sent to CEA for

finalizing annual generating target for the Year 2013-14 & uploaded at WRPC website.


A meeting for finalizing the generation target in respect of various generating units

including IPPs for the year 2013-14 was organized by CEA on 28.01.2013. It was

requested that IPPs expected to commence delivering of power in WR grid during year

2013-14 may furnish month wise generation for intimation to CEA for further needful.

Regarding the Annual LGBR for 2013-14 based on data received so far WRPC,

preparation of draft Annual LGBR is under progress.

WRP Committee noted. ITEM NO 8: UP-GRADATION OF BINA-GWALIOR-AGRA LINK TO 765 KV LEVEL: Member Secretary I/c, WRPC informed that PGCIL had proposed the up gradation of

400 kV Bina-Gwalior-Agra D/c line to 765 kV operation from the present 400 kV

operation. The OCC Sub-Committee discussed the up-gradation work of 765 kV

Bina-Gwalior-Agra link. With the present level of power transfer at 765 kV level to

NR, they apprehended a very high voltage situation particularly in Seoni, Bina,

Gwalior areas. Already many lines are kept open to curtail high voltage. There

seems to be no significant increase in generation levels and therefore charging at

765 kV level will increase the voltages further. Accordingly the sub-committee

requested POWERGRID to carry out necessary studies, in line with the present

generation and anticipated generation and off-peak scenario in WR and chalk out the

reactive power absorption requirements so that up-gradation to 765 kV operation of

the above lines may eventually take place. The results of the studies were to be

discussed in the OCC/ Study forum of WR before operation at 765 kV levels

commence.

PGCIL performed the studies to assess the operational impact before and after up

gradation. The results of the studies were discussed in the OCC. WRLDC expressed

the need to have ICT at Gwalior before the up gradation can be permitted. The

studies did not consider the generation at Sasan, which was to come shortly. Hence

the voltages after Sasan generation comes up, would be under control. PGCIL

informed that 4 x 240 MVAR reactors(2x240MVAR at Bina and 2X240 MVAR at

Gwalior) were installed on the 765 kV Bina Gwalior line. During the off peak months


from June to August the power flow in NR is likely to increase as the loads in NR

pick up. Hence the Power flow on the above corridor will increase and control the

voltages. The OCC recommended that in view of the above the planned up gradation

work can be taken up by PGCIL. Further the dates were scheduled by the OCC in

March 2013.

The TCC discussed the recommendations of the OCC and after discussion

recommended that PGCIL can take up the up gradation work. PGCIL was advised to

carry out the work after taking all precautionary measures and complete the up

gradation work in the month of March 2013.

The TCC also agreed with the recommendation of reviewing the SPS accordingly. WRPC accepted the recommendations of the TCC.

ITEM NO 9: DECISIONS ON IMPORTANT ITEMS FROM 35TH SCM HELD ON 03/01/2013 AT GURGAON: Member Secretary I/c, WRPC informed that the following important decisions taken in the above SCM. (For details kindly refer to the MOM of 35th SCM.)

A. Commissioning of 400/220 kV 315 MVA ICT at Vapi(PG) and establishment of 400/220 kV Kala s/s in DNH

1) In the 35th SCM matter pertaining to critical loading of GETCO system and

commissioning of 400/220 kV 3rd ICT at Vapi(PG) was discussed.

2) Since a substantial quantum of DD and DNH was being catered through

GETCO system and resulting in the critical loading of 220/66 kV ICTs at

Bhilad and Vapi GETCOI s/s, it was decided that after the commissioning of

3rd ICT at Vapi(PG), in case critical loading of GETCO system is not relieved,

a meeting of the stakeholders would be convened to review the 66 kV

interconnections between GETCO system and DD & DNH systems.

3) Due to ROW constraints in DD/DNH system, the earlier agreed arrangement

was modified as follows:

(i) 220 kV Kala – Khadoli D/c

(ii) 220 kV Kala – New Kharadpada switching s/s D/c

(iii) 220 kV New Kharadpada switching s/s – Kharadpada D/c


B. Reactor at 400 kV Bina s/s It was decided to replace the 63 MVAR Bus Reactor at Bina(PG) by 125

MVAR Bus Reactor and keep 63 MVAR Bus Reactor as regional spare.

C. Increase in provision of PMUs under URTDSM In order to encourage vendors to set up manufacturing and O&M support

facilities for PMUs in India, the provision for indigenous PMUs under

URTDSM was raised to 30% from 15%

D. Proposal for Static VAR Compensator (SVC)/STATCOM in WR In line with the Recommendations of Enquiry Committee of Grid disturbances

in NEW grid in July 2012, regarding installation of adequate static and

dynamic reactive power compensators , the SCM, on basis of system studies,

has decided to install in the first phase SVC’s/STATCOM’s at following place

in WR

1) Gwalior +/- 400 MVAR

2) Sholapur(PG) +/- 400 MVAR

3) Aurangabad(PG) +/- 400 MVAR

4) Satna +/- 400 MVAR

E. Termination of Vapi-Navi Mumbai 400 kV D/c line at Kudus s/s (MSETCL) 1) Due to severe ROW problems, forest, wildlife and eco-sensitive zones

clearances pending, the 35th SCM decided that the 400 kV Vapi-Navi

Mumbai line shall be terminated at Kudus s/s near Padghe. However

PGCIL shall continue the efforts to complete the balance portion of Vapi-

Navi Mumbai line.

The followings are other decisions of MOM of the 35th SCM.

1. Laying of Multi circuit towers near approach end of 765/400kV Vadodara GIS substation. The 765/400 kV Vadodara GIS substation is under implementation by

POWERGRID as a part of WR System Strengthening for IPP projects in

Madhya Pradesh and Chhattisgarh (being pooled at Bilaspur Pooling station).

There are four number of 400 kV lines planned from the Vadodara 765/400 kV

substation:-


i. TEL (DGEN) TPS – Vadodara 400 kV D/C line (Transmission System

strengthening in WR for the 1200 MW LTA granted to DGEN TPS of Torrent

Energy Limited). This line will be implemented through tariff based competitive

bidding route.

ii. Vadodara – Asoj 400 kV (Quad) D/C line.( As a part Transmission System

Strengthening in WR associated with New IPP projects in Chhattisgarh)

Implementation by POWERGRID.

iii. Vadodara – Pirana 400 kV D/C (Quad) line. (As a part of Transmission System

Strengthening in WR associated with IPP projects in Madhya Pradesh and

Chhattisgarh being pooled at Bilaspur Polling station).Implementation by

POWERGRID.

iv. Vadodara – Vataman 400 kV D/C (Quad ) line. (As a part of transmission

system associated with 3960(6X660) MW Chhattisgarh UMPP) implementation

by POWERGRID.

Due to Severe RoW problems being faced in laying of the above transmission

lines near Vadodara substation it was decided to lay these lines on two nos. of

multi-circuit towers for about 3 kms length from the Vadodara substation. Based

on the route alignment, following was agreed:

(i) Vadodara – Pirana 400 kV (Quad) line & Vadodara – Vataman 400 kV (Quad)

D/C line on one multi- circuit towers.

(ii) Vadodara – Asoj 400 kV (Quad) D/C line & Vadodara – DGEN 400 kV D/C

(Twin) line on the other multi-circuit towers.

It was agreed in the meeting that the 3 km corridor of the Vadodara – DGEN

400 kV D/C line from Vadodara which is proposed on multi circuit towers may

be implemented by POWERGRID and the line beyond the multi circuit portion

may be implemented under tariff based competitive biding route.

2. Direct Interconnection of Vadodara – Pirana and Vadodara – Asoj 400kV D/c (Quad) lines by passing Vadodara substation as an contingency arrangement. The transmission scheme associated with WR System Strengthening for IPP

projects in Madhya Pradesh and Chhattisgarh (being pooled at Bilaspur pooling

station) as given under, is under implementation by POWERGRID.

(i) Indore – Vadodara 765kV S/c line

(ii) Vadodara – Pirana 400kV D/c quad line


(iii) Establishment of 765/400kV, 2x1500MVA GIS S/s at Vadodara.

In view of the delay in completion of Vadodara 765/400 kV substation and

expected completion of the Vadodara – Asoj 400 kV D/C line and Vadodara -

Pirana 400kV D/c line by September / October 2013, direct interconnection of

400 kV lines at suitable location, by passing Vadodara substation, as

contingency arrangement, was agreed in the meeting.

The interim arrangement shall be in place till the availability of 765/400kV

Vadodara S/s.

3. Commissioning of line reactors at Satna and Bilaspur 765kV substations. In the meeting, it was intimated that the 2x240 MVAR, 765kV switchable line

reactor at Satna substation for Sasan – Satna 765kV 2xS/c lines and

1x240MVAr, 765kV line reactor at Bilaspur substation for Bilaspur – Ranchi

765kV S/c line are available, while the associated lines are to be completed. In

view of the high voltages prevailing in Western Region during off peak

conditions, it was agreed in the meeting to utilize these line reactors as bus

reactors till the completion of the associated lines. Upon the completion of the

associated lines, these reactors would be utilized as line reactors.

4. Transmission system associated with new IPP projects in Chhattisgarh- shifting of converter terminal associated with +600kV 4000MW, Raigarh (Kotra) – Dhule HVDC line from Dhule in Western Region to a suitable location in Southern Region. The transmission system associated with new IPPs in Chhattisgarh, interalia,

included + 600 kV 4000 MW, Raigarh (Kotra) – Dhule (PG) HVDC bipole line

along with interconnection of Dhule (PG) with Malegaon, Nashik and Dhule

(IPTC).

Considering the requirement of transfer of power from Chhattisgarh to Southern

Region, it is decided in the meeting to shift the converter station associated with

the + 600kV, 4000 MW Raigarh (Kotra) – Dhule (PG) HVDC bipolar link

proposed at Dhule in Western Region to any suitable location in Southern

Region.

After discussion, the termination of + 600kV, 4000MW HVDC bipolar link from

Raigarh (Kotra) to suitable location in Southern Region, instead of Dhule in

Western Region, was agreed in the meeting. Thus, the transmission system

associated with new IPPs in Chhattisgarh is modified as under:-


+ 600 kV, 4000 MW HVDC bipole between Raigarh pooling station (near

Kotra) to a suitable location in Southern Region along with metallic return

conductor.

Establishment of 4000 MW, +600 kV HVDC bipole terminal each at

Raigarh (Kotra) and at a suitable location in Southern Region.

Deletion of establishment of 2X315 MVA, 400/220 kV substation at

Dhule (PG) along with 400 kV interconnections of Dhule (PG) with Dhule

(IPTC), Nashik and Malegaon.

5. Review of Transmission system for transfer of power from IPPs of SR to WR/NR. It was intimated in the 35th SCM meeting that the implementation of

transmission scheme for transfer of Power from IPPS in Southern Region to

Western Region/ Northern Region was not taken up by POWERGRID due to

slow progress of generation projects in Southern Region.

Further, in the northern region grid, following changes have taken place:-

(a) UP is establishing a 765 kV substation at Greater Noida under PPP mode

which is close to Bulandshahar S/s. Two 765 kV substations in close

proximity is not desirable.

(b) Kanpur – Jhatikara 765 kV S/c line is under construction, which is about

450 km long and for smooth operation, it is desirable to LILO this line at

some substation to reduce its length.

(c) Earlier a 765/400 kV substation at Sonipat was planned, however with the

coming up of CLP Jhajjar and Aravali. Jhajjar generations as well as

considering the injection of power from Adani at Mohindergarh, there is a

need to review the requirement of establishment of 765/400kV substation

at Sonipat.

In view of above, it was discussed that the establishment of 765/400 kV

substation at Bulandshahar may be shifted to Aligarh and Kanpur-Jhatikara 765

kV S/c line may be LILOed at Aligarh. Further, for power dispersal from Aligarh,

a 765 kV D/c line may be taken towards Hapur substation. Accordingly, it was

agreed to take up the Transmission scheme for transfer of power from IPPs in

SR to WR/NR as WR-NR System strengthening scheme with following

modifications:-


(i) Solapur – Pune 765kV S/c (2nd) line.

(ii) Jabalpur Pooling station - Orai 765 KV D/c line.

(iii) Orai – Aligargh 765kV D/c line.

(iv) Aligarh – Hapur 765kV D/c line.

(v) Orai – Orai (UPPTCL) 400kV D/c (Quad) line.

(vi) LILO of one circuit of Satna-Gwalior 765 KV line at Orai S/s.

(vii) 2x1000MVA, 765/400KV substation at Orai S/s.

(viii) LILO of Agra-Meerut 765 kV S/c line at Aligarh S/s.

(ix) 2x1500MVA, 765/400KV S/s at Aligarh.

(x) LILO of Kanpur – Jhatikara 765 kV S/c at Aligarh S/s.

6. Strengthening of ISTS system in Gujarat – Proposed by GETCO. In the 35th SCM, it was deliberated that it is necessary to have sufficient STU-

CTU interconnections in Gujarat as a number of generation projects are coming

up in Gujarat and IPPs in other states have indicated Gujarat as target

beneficiary.

The necessity of strengthening STU-CTU interconnections was also discussed

in meeting on High Capacity Transmission Corridors held in CEA in Oct, 2012.

Further, Gujarat has highlighted on several occasions that a substation in

Saurashtra is needed to be set up to cater to increasing load of that area.

Considering the above, following STU-CTU interconnections were discussed in

the meeting to be implemented under ISTS:

a) Establishment of new 765/400kV, 2x1500MVA Pooling Station in

Saurashtra area

b) Saurashtra Pooling Station — Vadodara 765kV D/c line

c) Saurashtra Pooling Station — Halvad 400kV D/c line

d) LILO of both circuits of Mundra UMPP — Jetpur 400kV D/c (Triple

conductor) at Saurashtra Pooling Station

e) LILO of both circuits Of Mundra UMPP — Limbdi 400kV D/c (Triple

conductor) at Saurashtra Pooling Station (LILO of one ckt of Mundra UMPP

— Limbdi 400kV D/c at Halvad may be opened after implementation of this

scheme)


In future, this Pooling Station shall be connected to Essar (Salaya)

generation project when additional LTA from this project is applied by M/s

Essar.

Further, it was deliberated in the meeting that in order to meet the

increased demand of DNH/DD and Navi Mumbai area, Kosamba- Vapi

(PG) 400kV D/c line, was required on urgent basis and the same shall be

implemented as ISTS line by POWERGRID, which was earlier proposed to

be implemented by GETCO.

PGCIL agreed to look into the same. WRPC noted ITEM NO 11: PROCUREMENT OF SOFTWARE: Member Secretary I/c WRPC informed that at present the WRPC Secretariat

is issuing accounts for commercial accounting. The existing software’s for UI and

REA were developed using earlier Visual Studio Platforms procured about 10 years

back. The complexity of mechanism has increased over the time with Inter-Regional

transactions, frequent revisions are necessary. Further new regulations for RTA,

RTDA, RRF etc., are coming in place. For RTA and RTDA software is developed

from local vendor and has a small AMC component. Other software’s have to be

shifted to newer platforms of Visual Studio 2012. Since the bills of the utilities have

huge financial implication, so prompt and error free accounting is the need of the


present. The manpower at WRPC is limited and so technological software solution in

the form of getting some software’s developed / maintained from local vendors is

required. Some in-house development is also envisaged. It is necessary to procure

Visual Studio 2012 for the same.

In view of the above, following proposals are made 1) Renewal of existing AMC for software maintenance for RTA and RTDA

2) Procurement of Visual Studio 12

3) Software help for revision of REA/UI for previous cases

The expenses for the above can be met within the existing contingency fund and

would be of the order of Rs 3 lakhs.

The TCC discussed the matter and recommended the same.

WRPC agreed to the proposal.

ITEM NO. 12: RENEWABLE REGULATORY FUNDS MECHANISM:

Member Secretary I/c, WRPC informed that the Hon’ble Commission

further through its order dated 16th Jan’2013 in petition no.209/2011 in the matter of

the Renewable Regulatory Funds Mechanism under Central Electricity Regulatory

Commission( IEGC) Regulations 2010 has directed the following .

1. RRF Mechanism shall come into effect from 01.07.2013.

2. ABT meters are required to be installed only in the Pooling Stations which

should be done expeditiously. In case the ABT meters are not installed by the

respective State Transmission Utility or Distribution Utility by 31.03.2013, the

same may be installed by CTU at the cost of concerned State Transmission

Utility/ Distribution Utility.

3. Mock exercise for forecasting and scheduling start w.e.f 01.02.2013.

The following is the brief on the Commission’s order dated 16th Jan 2013

1. Any person could become the coordinating agency, which may be one of the

generators or any other mutually agreed agency. This agency shall be

referred as “Coordinating Agency” for the purpose of scheduling, metering

and energy accounting.

2. Pooling Stations that are commissioned on or after 03.05.2010 should be

considered for the purpose of RRF mechanism. Accordingly the IEGC-2010

would be amended by the Hon’ble Commission.


3. Payment should be similar to the conventional generators i.e. Wind and Solar

generators should be paid at the contract rate as per the schedule and UI

mechanism would ensure, the liability of which would be in accordance with

the dispensation for Wind generators in the Grid Code.

4. Reference rate for contract is fixed as Rs.4/kwh fro NEW grid and Rs.5/kwh

for SR grid.

5. Mutually agreed mechanism shall be developed by the coordination agency

and the Wind generators connected to that pooling station on account of

sharing the variations with reference to the schedule. In case of

disagreement, the UI charges should be shared based on actual generation

on wkly basis.

6. The IEGC_2010 and the approved detailed Procedure for implementation of

RRF will be amended/revised in line with the above proposals.

WRLDC vide letter dated 4th Feb’2012 had requested all SLDCs to send the

required data to WRLDC on weekly basis for the previous week for preparation of

energy accounts by WRPC secretariat. The copy of the letter is enclosed at

Annexure-12. In this regard the following points needs to be discussed:

Modalities of weekly sending the required data in the enclosed format

SLDCs may intimate the coordinating agency for the purpose of scheduling,

metering and energy accounting.

Status of availability of ABT meters at Pooling stations

SLDC,GETCO informed that data for RRF is being received and the same is being

forwarded to WRLDC/WRPC in the prescribed format.

SLDC,MSETCL informed that they would be submitting the data in the prescribed

format shortly.

Member Secretary I/C informed that development of software from small vendors

and associated Hardware(PC) was required for which about Rs. 7 Lakhs was at

present estimated.

This amount, along with Rs 3 Lakhs for software procurement in item no 11, works

out around Rs 10 Lakhs and it was to proposed to meet the expenditure partially


from existing contingency fund and balance through appropriate increase in the

contribution towards contingency fund for 2013-14.

WRPC agreed to the above of expenditure of around Rs 10 lakhs towards software development and hardware requirements(PC) for implementation of commercial mechanism to be funded through contribution towards contingency fund.

ITEM NO. 13: EVACUATION OF POWER FROM KORBA STPS-III OF NTPC. Back Ground : In the matter of evacuation of power from Korba unit 7 of stage III of NTPC

station after declaration of commercial operation (COD) of the unit till commissioning

of the identified 400 kV Raipur-Korba D/c line, Hon’ble CERC vide para no 32 of

order dated 6.9.2011 in petition no 122/2011 has directed as follows:

Quote:

“In view of the foregoing discussion, we have come to the conclusion that the

petitioner is bound by the terms and conditions of the BPTA and the Implementation

Agreement signed by it with the CTU. However, after allocation of power from

Korba-III by Government of India, Ministry of Power to the western region

beneficiaries and execution of PPAs by the petitioner, the western region

beneficiaries have become long term customers by operation of Regulation 2(1)(m)

of the Connectivity Regulations. The long term customers have right to schedule

power on long term access from Korba-III on the available spare capacity and such

scheduling shall have priority over the medium term open access and short term

open access. The ATS for Korba-III was declared under commercial operation with

effect from 27.6.2011. Consequently, scheduling of power from Korba-III for the

period from 21.3.2011 to 26.6.2011 on the existing transmission capacity shall be

deemed to have been made on long-term access. The energy and UI accounts shall

be revised and settled accordingly. “

Un-Quote

The WR Power Committee in the 18th WRPC meeting held on 1.10.2011 decided

that WRLDC would refund whatever charges collected by WRLDC from all the

constituents on account of short term scheduling of power from Korba-III and would


furnish necessary data to WRPC Secretariat to revise the energy and UI accounts

and suggested that accounting details may be finalized based on data to be

furnished by WRLDC in line with the above mentioned CERC order dated 6.9.2011.

In order to implement the above order of Hon’ble Commission, WRLDC have

submitted the 15-minute block-wise data viz DC of unit no 7 of Korba-III,

entitlements of beneficiaries of Korba-III, their Long-Term schedules from Korba-III

and related data necessary for preparation of revised energy and UI accounts data

on 08.02.2012. Accordingly, the REAs have been revised on 30.03.2012.

During examination of revision of UI based on the data submitted by WRLDC it

was observed that the revised schedules submitted by WRLDC remained

unchanged and there would not be any change in payable/receivables on account of

this for the above period. Hence the revision of UI A/c’s was not undertaken.

In the 61st CCM, while discussing examination of the revision of UI, beneficiaries

expressed that during few occasions they were unable to revise the schedules since

the schedules were treated as STOA and any revision of the requisitioned schedules

would not have been effective before expiry of a minimum period of two (2) days and

not from the fourth time block as in case of LT schedules. Conversion of STOA

schedules of beneficiaries to LTA schedules without any change in schedules due to

revision of DC (as available in LTA schedules) have deprived the beneficiaries to

avail the benefit of revision of schedules due to revision of DC which otherwise

would have been available had the schedules been treated as LT schedules.

The Commercial Committee suggested forming of a small group comprising of

members from constituents, NTPC & WRLDC who would look into such instances

and the practicability of implementing post-facto revision of schedules and give its

recommendation accordingly.

The group met on 14.05.2012, and it was decided that NTPC would submit

following data for the period 21.3.2011 to 30.6.2011 for revision of schedules:-

(i) date and time of tripping of Korba-III unit

(ii) declared date and time of restoration of the unit

(iii) actual date and time of restoration of the unit

(iv) DC prior (at the time of tripping)


(v) DC after restoration (at the time of restoration of the unit).

During the 20th WRPC meeting held at Indore on 18.05.2012, WRLDC and PGCIL

representatives informed that a petition has been filed with Hon’ble Appellate

Tribunal against the above order of Hon’ble CERC by PGCIL. MPPMC in the

meeting requested to issue the revised UI account in defined time frame preferably

before next WRP Committee meeting to be held in September 2012, which was

agreed by the WRP Committee.

WR Power Committee in 20th WRPC recommended that since there is no stay on

Hon’ble CERC order by Hon’ble Appellate Tribunal, the CERC directives could be

acted upon so that the dues are settled as per CERC order, revision of UI A/c’s shall

be carried out by WRPC on receipt of revised data from WRLDC.

As decided by small group comprising of members from constituents, NTPC &

WRLDC regarding submission of data by NTPC, NTPC vide email dated

01.06.2012 submitted the data which was circulated to the beneficiaries and

WRLDC for validation vide WRPC letter WRPC/Comml-I/3/ABTREA/2012/739

dated 01.06.2012 and reminder to beneficiaries for forwarding their comments if any

by 25.06.2012, vide letter WRPC/Comml-I/3/ABTREA/2012/864 dated 20.06.2012.

MPPTCL vide their letter 07-05/RPC-14/1273 dated 14.06.2012 have intimated that

the data submitted by NTPC was verified and is in order.

WRPC vide letter WRPC/Comml-I/3/ABTREA/2012/904 dated 26.06.2012

requested WRLDC for revision of schedules based on the data forwarded,

observations of GUVNL and as per the decision taken in the meeting held on 14th

May 2012 at WRPC.

WRLDC vide letter WRLDC/MO-II/2012/6806 dated 13.08.2012 have intimated

that the Data forwarded in the above matter only contains tripping details of NTPC

Korba Stage-III and with this data, the schedules cannot be revised and 96 block

wise DC which is agreeable to all the constituents is required for revision in

schedules of NTPC Korba Stage-III. Further POWERGRID did not agree with the

aforesaid CERC order dated 06.09.11 and has submitted its appeal before Appellate

Tribunal against the CERC order. The same has been accepted by Appellate

Tribunal and the first hearing already taken place on 23.07.2012. Further they have


intimated that the matter is still sub-judice and the decision of Appellate Tribunal is

awaited, the matter will be settled after the decision of Appellate Tribunal.

WRPC in view of the decisions of 20th WR Power Committee, vide letter

WRPC/Comml-I/3/ABTREA/2012/1296 dated 17.08.2012, requested WRLDC to

review their stand expressed in the above letter.

WRLDC vide letter No. WRLDC/MO-II/2012 dated 07.11.2012 have forwarded the

revised schedules data as per the decision of 62nd CCM.

Discussion: SE(Comml), WRPC informed that REA and UI revisions with respect to

Korba-7 has been completed (UIs and REAs for the period March-11 to June-11

have been revised). The revision of REAs and UIs on account of inadvertent errors

in meter and scheduled data has been taken up and REAs & UIs for the month of

Feb-12 & March-12 have been completed.

TCC/WRPC noted the above.

ITEM No.14: SCHEDULING OF KAWAS AND GANDHAR: Background: In the 63rd CCM NTPC representative stated that the technical

constraints in running the units at lower than technical requirement of machines was

discussed and noted in 442nd and 443rd OCC meetings. NTPC requested

beneficiaries for scheduling of Kawas and Gandhar at least up to technical minimum

during night hours for on-bar gas turbines in combined cycle mode taking into

account their day’s total energy requirement. NTPC also intimated that Kawas and

Gandhar stations are getting schedules less than technical minimum during night

hours. Further, the less schedules during Night hours results in the unintentional

over injection by stations to maintain the technical minimum generation level.

Further, NTPC mentioned that, as per the latest Govt. notification, the under-utilized

portion of cheap domestic gas (APM) may get diverted to other stations.

In the 63rd CCM constituents responded that they are not in a position to accept the

to technical minimum schedule during night hours in view of strict adherence to merit

orders dispatch and injections due to must buy provision for purchase from

renewable sources (specifically wind energy in case of GUVNL) etc. Beneficiaries


also mentioned that although they are conscious of the fact that under-utilization of

cheap domestic gas allocated for Kawas and Gandhar may lead to its diversion, they

are not in a position to schedule this power in view of reasons cited above.

Discussion: In view of merit order dispatch basis, it was not possible for

constituents to give more schedules than present. NTPC suggested that the

schedule may be staggered in such a way that, the stations/ machines on bar would

be able to operate at technical minimum. TCC recommended that the matter may be

discussed separately where NTPC shall suggest a suitable method for scheduling for

above stations.

WRPC noted the above. ITEM No.15: DECLARATION OF TRANSMISSION ELEMENTS INTO

COMMERCIAL OPERATION BY PGCIL. Member Secretary I/c, WRPC informed the following:

enclosed at Annex.-15.6) have intimated that the 125MVAR, 400kV three

phase spare Reactor has been procured for Itarsi S/S under “Provision for

spare ICTs & Reactors for Eastern, Northern, Southern and Western Region”

and the same has been put into commercial operation in WR w.e.f.

01.01.2013. Accordingly, the monthly transmission charges for above

transmission systems will be payable from 01st January 2013 by all

concerned DICs as per CERC (sharing of inter-state transmission charges &

losses) Regulation 2010.

In the 63rd CCM, MPPMCL representative intimated that procurement of an

element can not qualify for putting it in Commercial Operation. As per the

CERC (Terms and Conditions of Tariff) Regulations, 2009 “ in relation to the

transmission system, the date declared by the transmission licensee from

0000 hour of which an element of the transmission system is in regular

service after successful charging and trial operation” and therefore sought

clarifications on whether the element can be declared into Commercial

Operation . since the elements was procured but not put in regular use, the

element can not be declared into commercial operation.

TCC recommended that since the matter was discussed in the 15th WRPC

meeting wherein it was decided that the expenditure of procurement of spare

transformers and reactors be met from PSDF or through normal process, and

therefore the monthly transmission charges for above spare transformer and

reactor will be payable by all DICs from the respective dates declared by

POWERGRID and requested POWERGRID to clarify whether the above

element is received and the recordings at Item No.10.1.(i) of 15th WRPC

meeting have been adhered to. Power grid confirmed the same.

The TCC recommended since already high voltages are present, the existing spare reactor may be utilized at Solapur immediately. Similarly as other spare reactors in this scheme are procured, they shall also after discussion, be shifted to appropriate locations. WRP committee agreed to above proposal of TCC.



enclosed at Annex.-15.7) have intimated that interconnection of “400kV D/C

(Quad) Vindhyachal-IV (NTPC)-Vindhyachal (Pooling station)” along with

“400kV D/C (twin) Vindhyachal pooling station-Sasan line [by passing

Vindhyachal pooling S/S]”, thus making it direct “400kV D/C Vindhyachal-IV-

Sasan line” to facilitate the evacuation of power from VSTPP-IV Generation

Project (under contingency plan) associated Transmission Scheme for

“Rihand-III & Vindhyachal-IV” has been charged successfully on 29.12.2012

and put into commercial operation w.e.f. 01.01.2013. This is as per approval

from CEA vide letter no.26/10/2012/SP & PA/1244 dated 26.11.2012.

Accordingly, the monthly transmission charges for above transmission

systems will be payable from 01st January 2013 by all concerned DICs as per

CERC (sharing of inter-state transmission charges & losses) Regulation

2010.


enclosed at Annex.-15.8) have intimated that 765kV S/C Sasan-Satna Ckt-I

at 765kV level (as per original scheme of Sasan UMPP) T/L has been

completed. Charging clearance from CEA has been received on 21.12.2012.

This T/L shall be charged and synchronised at rated voltage as and when the

switchyard of SASAN UMPP is ready for commissioning. This is in line with

the in-principal approval by CEA vide their letter ref:

26/10/2012/SP&PA/1244 dated 26.11.2012. Accordingly, the monthly

transmission charges for above transmission systems will be payable from

01st January 2013 by all concerned DICs as per CERC (sharing of inter-state

transmission charges & losses) Regulation 2010.

In the 63rd CCM, SLDC GETCO representative stated that till an element of a

transmission system is required to put in regular service after successful

charging and trial operation. Therefore the above element can only be

declared into Commercial Operation after it is put into regular service after

successful charging and trial operation.

Commercial sub-Committee approved the observation of GETCO and

expressed that date of Commercial Operation of the above element be

considered after compliance of the above condition.


15.8 Regarding case of earlier COD for reasons not attributable to PGCIL,

the decision rests with CERC. Hence TCC after discussion, informed that as per

existing regulations on the matter, for elements that are put in regular service, the

COD shall be the 1st of the following month which can be noted by the RPC. For

cases where the PGCIL has completed its contractual obligations and regular

service is not possible for reasons beyond control of PGCIL, the deciding authority

is the Hon’ble Commission CERC. In this case PGCIL have completed their

commissioning activities, but the element could not be put in regular service as bay

at Sasan was not ready. Hence PGCIL may seek the Commission’s decision for the

COD. WRPC noted/agreed. ITEM No.16 : SCHEDULING ISSUES AT NTPC STATIONS DURING FUEL SHORTAGE CONDITIONS: Background: Member Secretary I/c, WRPC informed that GUVNL vide letter No.

GUVNL:GM(Com.):209 dated 31.01.2013 (copy enclosed at Annex-16.1) have

intimated that the entitlement of GUVNL in respect of NTPC generating stations

namely Vindhyachal-1,2,3, and Sipat-1,2 as per the data of WRLDC web site for the

month of Sep 12 to Nov 12 is not matching with the entitlements / availability

certification in the monthly REAs issued by WRPC. Further, the scheduled energy of

GUVNL in respect of NTPC generating stations is substantially less than entitlement/

availability certification of GUVNL certified in REAs. It is learnt that in case of NTPC

generating station the availability of the station has been considered on the basis of

maximum availability / generation during peak hour of that day applied for full day,

even though the plant availability for generation during off peak hours was less due

to fuel shortage.

The matter was deliberated in the 63rd CCM and following observations were made

MSEDCL representative stated that they have taken up the issue with NPC vide

letter No. CE/PP/NTPC/33820 dated 06.12.2012 (copy enclosed at Annex.-16.2),

wherein the applicable provisions i.e. Chapter-3, clause-21 (4) of the CERC Terms

and Condition of Tariff Regulations, 2009 was cited. As per this provision, it is

mandatory for the generating company to obtain consent/clearance of the

beneficiaries of the power station before making any change in the operating pattern

in case of fuel shortage. However the consent was not obtained from MSEDCL.


During the fuel shortage period the scheduling is required to be optimized. As seen

from the data for the period mentioned it is observed that NTPC is deriving

incentives under fuel shortage condition which is against the spirit of recovery of

fixed charges.

GM WRLDC stated that the matter was deliberated in 52nd CCM & 10th WRP

Committee meeting held on 30th May 2009 at Diu and scheduling was done by

WRLDC in accordance to the decision taken.

Following was decided in case of fuel shortage in respect of NTPC stations in 52nd

CCM & 10th WRP Committee meeting:

(i) Peak Hours would generally be worked out by taking into regional load of

previous days or similar day of the previous week.

(ii) It would be of continuous 5 Hrs. (20 time blocks of 15 minutes)

(iii) The entire year will be divided in two seasons i.e. April to September as summer

and October to March as winter season.

(iv) Peak Hours during the months of April to September – 1800 Hrs to 2300 Hrs.

(v) Peak Hours during the months of October to March – 1700 Hrs to 2200 Hrs.

(vi) Dci will be taken equal to maximum ex-power plant MW schedule specified by

the WRLDC continuously during the above defined peak hours for that day.

GUVNL representative stated they are paying for the interest on working capital for

the storage capacity of coal for 45days and sustained fuel shortage declaration

for three months is not acceptable to them. He further stated that the approved

procedure in the 10th WRPC meeting does not give blanket approval to declare

fuel shortage at the will of NTPC without taking consent from the beneficiaries.

NTPC representative stated that they have followed all the relevant statutory

provisions as regards to declaring the fuel shortages.

Commercial sub-Committee felt that the matter requires further deliberations and

therefore a meeting may be convened. Member Secretary I/c, WRPC informed

that a meeting was held subsequently, but no consensus on the matter could be

arrived at.

Discussion: During the TCC, the matter was discussed. After discussion TCC

recommended the following regarding scheduling under fuel shortage

conditions:-


1) Regarding the future cases, the earlier procedure formulated in the 10th

WRPC meeting shall be discontinued. 2) In order to address the issue of scheduling under fuel shortage conditions,

WRLDC proposed that based on NTPC input of max MW, min MW and

energy availability for the day, WRLDC shall prepare average entitlements for

96 blocks. The beneficiaries may then give their schedules. DC will be taken

equal to the maximum of the schedules throughout the day. The same shall

be discussed in a separate meeting and detail shall be worked out. 3) It was also recommended that, WRLDC shall henceforth bring to the notice of

the beneficiaries, through SLDC, fuel shortage position intimated by NTPC

under regulation 21(4). Since the scheduling under this condition has

commercial impact, WRLDC was requested to separately highlight such

messages from the normal scheduling messages. 4) Regarding the past period, Constituents pointed out that while there was low

energy output around 77% NTPC receives incentives during fuel shortage

period, due to the procedure under regulation 21(4) which does not appear

fair to the constituents. Hence it was suggested that NTPC may agree to

restricting their availability to normative availability under fuel shortage

conditions at least from the period when MSEDCL first pointed out the above

situation (Letter of Dec 12 which points to the period from Sept 12) . If so

WRLDC shall revise the DCs and entitlements accordingly. 5) NTPC informed that they are in not agreement for revision of REAs during fuel

shortage conditions from September 12 onwards, as NTPC have followed all

the relevant regulatory provisions.

The WRPC once again discussed the above points. The points 1,2 and 3 for

the future procedures in principle, was agreed by WRPC and WRPC

instructed to formulate the detailed procedure in a separate meeting.

Regarding the revision of the past REA’s for the period from Sept 2012

mentioned in MSEDCL letter, WRPC once again requested NTPC to restrict

their availability to normative availability under fuel shortage conditions. NTPC

reiterated that they have followed the prescribed procedures under the

regulation 21(4) and the procedure adopted by WRLDC was in line with the

prevalent WRPC agreed procedure, and hence NTPC did not agree to the

above request of WRPC. WRPC then requested WRLDC to revise the DC for


the above period for further revision of REAs and suggested that if NTPC

was not agreeing to the same, they may approach the Hon’ble Commission if

they feel so.

It was agreed to hold separate meeting to detailing the future procedure to be adopted and also scheduling of NTPC Kawas and Gandhar to technical minimum level. ITEM No 17: OUTAGE PROGRAMME OF TRANSMISSION LINES/ELEMENTS

Member Secretary I/c WRPC informed the procedures followed in the OCC for line

outage planning and the same are given below:

A. Line outages planning The line outage planning is becoming very complex day by day, and therefore needs

sophisticated and better planning well in advance. As per IEGC the outage planning

of transmission elements is generally done in OCC. Considering the complexity pre -

OCC meeting is being held in which the line outages planning is done on calendar

month basis. B. Line outages planned vs. implemented:

The status of line outages planned in OCC vs. outages availed and any

deviations from planning or emergency outages for the concerned month are being

discussed in OCC and defaulters are requested to explain the reason of deviation.

C. Code giving procedure:

Since short term market clearance depends on available transmission capacity & is

cleared on day ahead basis, there is a need for better planning. In this regard OCC

formulated the following guide lines for better operation:

(A) All utilities shall confirm on D-2 about readiness to avail outages(where D is date of outage).

(B) WRLDC shall issue code in real time within 10 minutes either to avail or cancel depending on real time conditions.

(C) All utilities do not confirm by D-2, those outages shall be deemed to be cancelled.

D. Inter regional line Outage planning:


As per letter no. 7 /AI/GD/GM-2012, dated 7th Sept., 2012 from Member (GO & D),

CEA, OCC clear NOC for outage of the inter-regional lines in respect of Western

Region. NLDC coordinates inter-regional outages under intimation to

WRPC/WRLDC. WRLDC coordinates in real-time and also along with line outages

already agreed in OCC.

Item No -27(SA 1 ): Interim connectivity to CTU network for M/s IEPL unit no -1(270MW) for testing and commissioning : Member Secretary I/c WRPC informed that 2X270 MW IPP of M/s IEPL has been

granted connectivity by MSETCL by LILO of one ckt of 400 kV D/C line from Koradi

towards Wardha. As this line was getting delayed because of forest clearance


issues, based on the recommendation of MSETCL, M/s IEPL was granted

connectivity by LILO of one circuit of Mauda-Wardha 400 kV D/C (quad) line till

MSETCL line gets commissioned for providing start up power to their first unit of 270

MW. This connectivity was only for taking start up power. Now M/s IEPL wants to

synchronize its units for testing and commissioning which involves injection of power

in the grid. As the 400 kV D/C line from Koradi towards Wardha is yet to be

completed, MSETCL has requested to allow M/s IEPL to inject power in Mouda –

Wardha 400 kV line as an contingency arrangement till their line gets commissioned.

He further informed that in this matter, a meeting was taken by Chairperson CEA on

20.02.2013 at CEA New Delhi & following was concluded:

(i) Member Secretary, WRPC will discuss with the WR constituents to consider

injection of power by M/s

IEPL for testing and commissioning on opportunity basis.

(ii) After receiving the concurrence of WRPC, the CTU will modify the tripartite

connection agreement

with IEPL to include injection of power as per CERC regulations on connectivity.

(iii) WRLDC may allow injection of power for testing and commissioning 1X270 MW

unit of M/s IEPL on opportunity basis.

The matter was discussed in the TCC, whether it was be possible for WRLDC to

allow injection of power for testing and commissioning on opportunity basis. WRLDC

informed that the present conditions of the grid beyond Wardha was critical and

lines were loaded beyond 530 MW. Also Moudha generation unit no 1, of NTPC was

also scheduled to come shortly. Hence it was difficult to absorb any power from M/s

IEPL on opportunity basis. Further in view of protection difficulties being faced due to

LILO of Moudha -Wardha line at IEPL and proposed synchronization of Moudha unit

no 1, he recommended that LILO at IEPL on Moudha-Wardha line may be removed.

The TCC noted the views of WRLDC and after discussions, recommended the same

for WRPC.


During the WRPC meeting Chairperson WRPC queried whether any definite period

was requested by M/s IEPL for injection of power. Member Secretary informed that

no definite period was requested by M/s IEPL or anticipated under testing conditions.

Chairperson queried the problems likely to be faced with injection at M/s IEPL on

opportunity basis. WRLDC pointed out that the power would flow to Wardha and line

loadings beyond Wardha were criticial. Also other STOA generators would require to

be backed down if more power comes from IEPL side. Hence due to these technical

constraints it was not possible to absorb the power from M/s IEPL.

Member Secretary I/c proposed that M/s IEPL may be permitted to inject the power

based on real time conditions. Director PGCIL, informed that due to W3 area and its

constraints, and a lot of generation is already backed down and under these

conditions injection of power by M/s IEPL may not be possible to be accommodated.

Chairperson WRPC requested Member Secretary I/c WRPC to record the above

views and discussions and inform Chairperson, CEA accordingly.

WRPC agreed to the above.

ITEM No. 28: DATE AND VENUE OF NEXT WRPC MEETING:

It was decided that as per the roster the next meeting shall be hosted by DNH. DNH

representative was requested to take up the same with their management and

convey their decision to Member Secretary I/c WRPC.

POSOCO

9.2.2 3 months A review of UI mechanism should be carried out in view of its impact on recent grid disturbances. Frequency control through UI may be phased out in a time bound manner and Generation reserves/Ancillary services may be used for frequency control. Appropriate regulatory mechanism needs to be put in place for this purpose.POSOCO should take up the matter with CERC

POSOCO

9.3 Immediate All STUs should immediately enable under frequency and df/dt based load shedding schemes. Central Commission should explore ways and means for implementation of various regulations issued under theElectricity Act, 2003. Any violation of these regulations can prove to be costly as has been the case this time.RPCs need to take up the matter for compliance. In case non-compliance persists, POSOCO should approach Central Commission.

STUs, RPCs, POSOCO Revised UFR and df/dt scheme implemented by all utilities. In case of WR getting isolated from rest of NEW grid to arrest high frequency operation and unplanned unit tripping few units have been identified for planned tripping at 51.5 Hz.

9.4 3 months All out efforts should be made to implement provisions of IEGC with regard to governor action. Central Commission needs to look into ways and means to hasten implementation of provisions of IEGC including that on governor action. POSOCO need to take up thematter with Central Commission.

POSOCO 191-No. of units eligible for RGMO 73- No. of units confirmed 13- No. of units exemption applied 109- No. of units in various utilities are yet to be made to participate in the RGMO Exemption not granted to any generator by CERC.

9.5.1 1 month POSOCO should take up with Central Commission the issue of inconsistency between Congestion regulation and the detailed procedure framed there under so thatcongestion due to forced outages and UnscheduledInterchange (UI) can be handled effectively

POSOCO

9.5.2 6 months NLDC and each RLDC should have one real-time security desk in all the shifts to be manned by engineer capable of carrying out TTC calculations. To facilitatethis, manpower at NLDC and RLDCs need to beenhanced with regulatory support to take care of financial aspects. Till this arrangement can be firmed up, various scenarios of outages could be built, which then can be used by despatcher in real time. Faster algorithm for calculation of TTC may be adopted by the load despatchers to update it in real time under outage

conditions.

POSOCO

9.6 Immediate Outage planning of inter-State and inter-regionaltransmission elements should be carried out in a coordinated manner at RPC fora (say Operation Co- ordination sub-committee of RPCs) in accordance with regulation 5 of Central Electricity Authority (Grid Standards) Regulation, 2010 and Section 5.7.1 of Indian Electricity Grid Code. In case need for emergency maintenance arises in between two meeting of Operation Co-ordination sub-committee, NLDC and RLDCs should allow such maintenance after carefully looking at prevailing system conditions under intimation to RPC

Secretariat

RPCs Already discussed and agreed in OCC of WRPC. 1. Interstate lines are coordinated by RPC/RLDC in monthly OCCs 2. Interregional lines are coordinated by NLDC in consultation with RPCs/RLDCs This is implemented and being regularly monitored in OCCs of WRPC.

9.7 6 months In order to avoid frequent outages/opening of lines under over voltages and also providing voltage support under steady state and dynamic conditions, installation of adequate static and dynamic reactive power compensators should be planned.

9.11 6 months In order to assess the system security in real time andassess the vulnerability condition of the system, dynamic security assessment need to be periodically carried out at the control centers. A proper review and upgradation of the state estimation procedure is required to improve the visibility and situational awareness of the system

POSOCO

9.12 Efforts should be made to design islanding scheme based on frequency sensing relays so that in case of imminent grid failure, electrical islands can be formed. These electrical islands can not only help in maintaining supply to essential services but would also help in fasterrestoration of grid

CEA, RPCs, POWERGRID, STUs, SLDCs and Generators 1.Mumbai, Ahmedabad , GTPS uran islanding schemes functional at present 2. Scheme for Bhopal city/ Bina Traction/JP Bina Power stn is under development. 3. All CPPs are planned for islanding at a lower frequency

than 48.8 hz i.e. final stage of UFR setting so that these stations are available for startup power.

4. APL-SPS, LANCO-SPS is already there. SPS for Agra-Gwalior, Zerda-Kankroli, Badod-Modak is planned. Units to be backed down in WR have been identified.

9.13.1 1 year As National Grid is on the horizon, homogenization of Govt. of India, State Govts system operation philosophy is need of the hour. The

present organizational set up of Load Despatch Centres need to be reviewed. System operation needs to be entrusted to Independent System Operator (ISO). In addition, SLDCs should be reinforced and ring fenced for ensuring functional autonomy 9.13.2 3 months Training and certification of system operators need to be Govt. of India, State Govts

given focused attention. Sufficient financial incentives need to be given to certified system operators so that system operation gets recognized as specialized activity 9.14 2 years Intra-State transmission system needs to be planned and

strengthened in a better way to avoid problems of frequent congestion

STUs

9.15.1 6 months Appropriate amendments should be carried out in Grid CEA Connectivity Standards to restrain connectivity of a generating station or a transmission element without required communication and telemetry facilities. 9.15.2 1 year

The Communication network should be strengthened by putting fibre optic communication system. Further, theCommunication network should be maintained properly to ensure reliability of data at Load Despatch Cenres

CTU and STUs Approvals by WRPC

• Addl. 2672 Kms of OPGW, 14kms of OFC along with wideband communication equipment of adequate capacity for setting up of back-up SLDC at Govindpura, Bhopal, connectivity of Sub-LDC Gandhinagar and Sub-LDC Jetpur to SLDC Vadodara (Gotri) on OFC with suitable end equipments.

• Existing communication equipments (SDH 37nos. & PDH 72nos.) to be replaced at the cost of 3.89 crores

• Installation of PABX System at SLDCs of Western Regions, WRLDC and NLDC

9.15.3 3 months RTUs and communication equipments should have CTU and STUs uninterrupted power supply with proper battery backup so that in case of total power failure, supervisory control and data acquisition channels do not fail 9.15.4 6 months In case of existing generating stations or transmission RPCs, POSOCO

elements without telemetry facility, the same should be New stations are mandated for data transmission through put in place at the earliest. If prolonged operation telemetry before commissioning. without telemetry continues, POSOCO should approach Central Commission

9.16 1 year Large variations are observed in time taken for initiation of unit start up (Boiler light up) by the stations afteravailability of start-up power and also for start ups/light up of subsequent units. While subsequent start-ups were very fast (10-20 minutes) in some of the units, in other cases they took considerably longer time – several hours. Reasons for the delays in attempting first start-up andsubsequent start-ups may be examined by the utilities in consultation with CEA. A standard procedure for preparatory activities and sequence of start up may beput in place by the stations to restore units as early aspossible particularly in contingencies.

CEA, Generating Utilities and RLDCs

9.17 3 months At inter-State level, the entire landscape has changed CEA over past few years. With de-licensing of generation and provision of open access in Electricity Act, 2003 and development of organized electricity markets, lot of generation is coming in the form of merchant generation. Four out of the five regions have been integrated and formation of National Grid is on the horizon. Under such scenario, there is need review the Transmission Planning criteria. 9.18 1 year There is need to reinforce system study groups in power

sector organisations to analyse the system behaviour under different network status/ tripping of lines/outageof generators. Where these do not exist, these should be created

CEA, CTU and STU

9.19 1 month It was felt that a separate task force may be formed,involving experts from academics, power utilities and system operators, to carry out a detailed analysis of the present grid conditions and anticipated scenarios which might lead to any such disturbances in future. The committee may identify medium and long term corrective measures as well as technological solutions to improve the health of the grid

MOP, CEA

9.20 1 year For smooth operation of grid systems, it is absolutelyimportant that all the power generating and distributing stations are connected on a very reliable telecom network. (i) A proper network may be built up preferably using MPLS(multy protocol label switching) which is simple, cost effective and reliable. In remote place where connectivity is a problem, the stations can use dedicated fibre cable from the nearest node (ii) Since POWERGRID has its own fibre optic cables, practically covering all major nodes and power stations, a proper communication/IT network may be built using dedicated fibres to avoid any cyber attach on the power system.
