The situation became critical due to simultaneous outage of 3 out of 4 circuits for approx.
four and half hours on 29.04.16 and station generation approx. 500 MW was flowing
through only available Dabhol- Nagothane – II. There was no redundancy available.
There would have been a station black out situation incase only available line tripped on
any reason.
He requested to look into the matter and suggest necessary preventive / corrective action
to avoid such critical situation.
The Sub-Committee may like to discuss.
ITEM NO. 8.6 CONTROLLING FAULT LEVEL AT RAIPUR & RAIGARH PSS/S OF PGCIL:

ITEM NO. 9: WRLDC ITEMS
9.1Blind fold operation –Threat for Grid SecurityIt is being observed that instances of loss of crucial real time data are increasing and
there is lack of matching response in restoring the same. Ideally there has to be
protection path from each nodes and n-1 criteria. The locations having major issues
are as under:
a) Non availability of data from VSTPS stage 3Data is not coming since 30/03/2016. The matter was escalated time and again.
Apart from compromising the Grid security, VSTPS 3 was not able to participate in
Ancillary services. NTPC to indicate the present status and action plan that in
future such loss of data is restored in 24 Hrs.
b) Highly intermittent data from Kolhapur GIS400kV Kolhapur GIS-Kudgi-D/C data is also being used to calculate the drawl of
Maharashtra. POWERGRID to share the network diagram and confirm that the
route is well protected.
c) Single path between Kalwa and WRTCCTelemetry from SLDC Maharashtra was down on 17th April 2016 from 11:30 Hrs to
21:00 Hrs due to fibre cut between Kalwa and WRLDC. Again it was down at about
1630 hrs of 21.04.16. There is single dark fibre available between Kalwa and
WRLDC which is prone to fibre cut and hence interruption. The 2nd route on OPGW
from Reliance may take another 2-3 months. Problem can be resolved if there is
second channel available between Kalwa and WRLDC. POWERGRID to indicate
the present status of arranging the 2nd channel.
d) Gateway problems at SolapurBoth gateways hanged on 16.04.16 ,which resulted incorrect computation of
drawal of Maharashtra. POWERGRID WRTS1 site representative informed that
these gateways are giving frequent problems and new gateways are under
procurement. POWERGRID to indicate the present status.

483rd OCC Agenda
e) RTU problem at TarapurTarapur Stage-2 data is not reporting at WRLDC due to suspected RTU problem at
Tarapur. POWERGRID to update the actions taken.
9.2Constraints in 400 KV Bableswar-Padghe corridorIt is observed that during high demand of the order of 18500-20000 in Maharashtra
during morning peak, the 400 kV Bableshwar-Padghe D/C is critically loaded to
more than 500 MW in each ckt. The 400 / 220 kV ICTs at Bableshwar are also
critically loaded and the area is N-1 non-compliant. The above constraints would
be addressed by following measures:
a. Commissioning of 400/220 kV Kudus sub-station and 400 kV Bableshwar-
Kudus D/C
b. Augmentation of 400/220 kV Transformation Capacity at Bableshwar
c. Interconnection of 400 kV Nasik with 220 kV Nasik old substation using idle
charged ICT at Rattan India Nasik.
SLDC MSETCL may update the progress of the above.
9.3 765/400 kV ICT at Tirora and 765/400 kV ICT at Akola II -- N-1 non-compliantThere is only one 765/400 kV ICT at Akola2 as well as at Tirora station of
MEGPTCL / APML. The N-1 criteria mandated by CEA Transmission Planning is
not getting satisfied at Tirora as well as at Akola2. The issue was being regularly
discussed in OCC till Oct-15. As per the last discussion, MEGPTCL had initiated
action for the amendment in transmission license for inclusion of these 2nd ICTs.
The approval from MERC was under process. MEGPTCL and APML to update the
progress and present status.
9.4 Insecure operation at 765/400 kV Ektuni765 kV Ektuni station of MSETCL has been charged through 765 kV Akola-Ektuni
ckt -2. With this the constraint of 765/400 kV ICT loading has shifted from Akola2 to
Ektuni. The station is handling more than 1000 MW of power. However the station
is N-1 insecure as it is operating with a single 765 kV Bus, single Bay and single
765/400 kV ICT. Present status may be reviewed.

9.5 Transmission system for Koradi St-II (3x660MW) and IEPL(2x270MW)Koradi-II S/S is connected to Wardha-Warora one ckt as an interim arrangement .
At present 2x660 MW units of Koradi-II and 1x270 MW of IEPL units are
commissioned (not scheduled at present by MSETCL). The generation at these
stations would be evacuated through 400 kV Koradi –II-IEPL-Warora S/C and 400
kV Koradi-II-Wardha S/C. With full generation at these station the system would be
N-1 non-compliant. WRLDC vide its letter dated WRLDC/ MO-III/1662/2016 dated
19th Jan 2016 had requested MSETCL to intimate the final arrangement for
evacuation of generation from Koradi-II and IEPL. MSETCL may update the final
arrangement for evacuation of Koradi-stage-II along with its progress.
9.6 Strengthening of Interconnection of Southern Gujarat and MaharashtraTransmission constraint is often experienced in lines connecting Southern Gujarat
with Northern Gujarat due to high demand and poor generation at the Kakrapar
APS and other Gas based stations in South Gujarat. South Gujarat is presently
connected to Maharashtra system through 400 kV Vapi-Boiser S/C and 220 kV
Nasik-Navsari D/C. Powerflow is generally from Maharashtra towards Gujarat on
these lines.
In Maharashtra system recent charging of Akola-Ektuni ckt at 765 kV level has
increased the availability of power at 400 kV Bableshwar. However in view of the
constraint at 400/220 kV level at Bableshwar, only one circuit of 400 kV
Taptithanda-Bableshwar is generally kept in service.
The constraints in South Gujarat and in Maharashtra system (Bableshwar)could be simultaneously addressed by strengthening the interconnection ofNavsari in Gujarat with Nasik in Maharashtra. Few suggestions in this regardare as under:
Option Proposal Impact on power system
A Interconnect 220 kV Nasik with400 kV Nasik and uprate theconductor of 220 kV Nasik-Navsari
This will help in relieving theconstraint at Bableshwar andenhance utilization of 220 kV Nasik-Navsari D/C. Both circuits of 400 kVTaptithanda-Bableshwar D/C can bekept in service.
B Upgradation of 220 kV Nasik-Navsari D/C to 400 kV by usingthe existing ROW.
This will help in dispersal of powerfrom Bableshwar relieving theconstraint at Bableshwar. Both

220 kV Nasik-Navsari is ajointly owned line of GETCOand MSETCL so STUs couldupgrade the sections lyingwithin their jurisdiction.
circuits of 400 kV Taptithanda-Bableshwar D/C can be kept inservice.
Action with regard to Option-A may be taken by MSETCL. The relevant extracts
from the CEA manual on Transmission Planning Criteria recommending utilization
of existing ROW for upgrading of existing AC lines to higher voltage level is quoted
below (emphasis added):
“3.11 The following options may be considered for strengthening of the
transmission network. The choice shall be based on cost, reliability, right-of-
way requirements, transmission losses, down time (in case of up-gradation
and re-conductoring options) etc.
o Addition of new transmission lines/ substations to avoid overloading ofexisting system including adoption of next higher voltage.
o Application of Series Capacitors, FACTS devices and phase-shiftingtransformers in existing and new transmission systems to increase powertransfer capability.
o Up-gradation of the existing AC transmission lines to higher voltageusing same right-of-way.
o Re-conductoring of the existing AC transmission line with higher ampacityconductors.
o Use of multi-voltage level and multi-circuit transmission lines.o Use of narrow base towers and pole type towers in semi-urban / urban
areas keeping in view cost and right-of-way optimization.o Use of HVDC transmission – both conventional as well as voltage source
convertor (VSC) based.o Use of GIS / Hybrid switchgear (for urban, coastal, polluted areas etc)”
The committee may like to deliberate.
9.7 Telemetry issues from Maharashtra Stations and POWERGRID StationsTelemetry issues from Maharashtra Stations have been flagged in various WRPC /
OCC meetings (since Dec’13). There is very close monitoring on Telemetry issues by
Hon’ble CERC. CERC order vide dt 29.1.16, directs all utilities to up-date telemetry
status in their system within one month of this order with an advance copy to NLDC,
respective RLDC and RPC. RLDC have been directed by CERC to monitor the
implementation of telemetry and in case of any difficulty, the matter has to be
discussed and sorted out in the RPC meetings. If any entities does not submit the
information, the concerned RLDC has to file application before the Commission
against the said entities under Section 142 of the Act. The status of telemetry for all

issue of intermittency.These are important Generating stations .
*** Bableswar, Khargar, Nagothane, Jejuri- MSETCL to give status for resolving the
issue of intermittency. These are important Load points
9.8 Implementation of Revised SPS setting for NEW GRID-SR as advised by NLDCThe envisaged SPS is for security of the interconnected system in case ofcontingencies. The perception of SLDC, MSETCL that 765 kV Solapur-Raichur linesare beneficial only for Southern Region is misplaced. The transmission systemassociated with SR-NEW Grid interconnection have helped in enhancing the reliabilityof East-West corridor within Maharashtra. Maharashtra has been able to meetadditional demand of ~ 4000 MW as compared to past. On several occasions theplanned/emergency outage of HVDC Chandrapur-Padghe could be convenientlyfacilitated due to availability of 765 kV Wardha-Aurangabad Q/C and 765 kVAurangabad-Solapur and 765 kV Solapur-Pune. The lines have rescued Maharashtraand Western Regional System during contingencies by dynamic MW as well as MVARsupport to Southern Maharashtra. During crisis manual picking up of generation atKoyna often gets delayed or constrained due to inadequate availability of water.

During 31st TCC/WRPC meeting it was advised to Maharashtra to explore their stand
on non participation in SPS 5 & 6 to NLDC who have formulated the scheme.
Maharashtra may either implement the SPS or convince NLDC about their action plan
during emergency situation of SPS 5 & 6.
Maharashtra SLDC may explain their stand.

Analysis of the events are tabulated below:
Station Remarks
Event-5 Frequency Response was observed from VSTPS-II, VSTPS-IV, VSTPS-V, Sipat-I, Korba-II, Mouda, CGPL, KSK and JPL.
NTPC Korba and NTPC Sipat have stage wise response of the event inexcel sheet.NTPC Mouda sent screenshot of the DAS at the station.
CGPL had forwarded the frequency vs MW data of 1 second resolution forunit 10, 20, 30 and 40. It is observed that the units are responding to thefrequency change, though the initial delay in response needs to beaddressed. It is understood that the units were operating in turbine followmode.
Response of VSTPS-III could not be analysed as SCADA data was notavailable from the station. Response of MB Power was not analysed as thegeneration was NIL.Sipat-II generation was ramping down, while JP Nigrie units had tripped atthat time.Sasan, APML, DB Power showed negative response i.e. generation

reduced instead of increasing. Sasan, APML and DB Power examine thesettings at their station and ensure compliance to provisions of the IEGC.
No response was visible from APL-II, APML Tirora and KWPCL. TheseStations have to send the frequency vs MW data (1 second interval) for theevent in Excel sheet to assess their response.
Event-6 Frequency Response observed from CGPL (with 3 min delay), KSK, JPNigrie and Mouda.No response observed at Sasan and JPL Tamnar. Negative responseseen at KWPCL. These stations to examine the settings and ensurecompliance to provisions of the IEGC.Response of VSTPS-II, III, IV, V, Sipat-I & II, Korba-II & III, APL-II & III,APML could not be analysed due to non-availability of telemetry from thesestations at the instant of the event.
Out of the six events analysed four events were of frequency dip. Under these events
generators were expected to pick up generation up to 105% of their Maximum
Continuous Rating. Vide CERC order dated 23.10.2015 in petition no. 302/MP/2013
dated in the matter of RGMO or FGMO with manual intervention (MI), CERC
mandated as under:
Quote
“22. On the issue of keeping margins while scheduling of the units, we are of the view
that the units should not be scheduled by RLDCs/SLDCs beyond ex-bus generation
corresponding to 100% of the Installed Capacity. Further, units should not be allowed
to operate with their valves wide open. This would ensure adequate primary response
by opening of the valve to the fullest.”
“33. With regard to the prayer of the petitioner to direct the generators to seek
approval of the Commission whenever the expected duration of outage of
RGMO/FGMO feature exceeds more than a week due to technical/operational
limitations, the Commission is of the view that requests for outage of RGMO/FGMO
with MI based on valid technical reasons, shall be dealt at SLDC/RLDC level. In case
of any dispute/difficulty, the matter should be resolved at RPC level at first instance.”
Unquote
In view of the above CERC order and IEGC provisions all generating stations need to
keep the RGMO or FGMO with manual intervention in service at all time. The upper

load limiter may be set at units to pick up generation upto 105% of MCR for short
duration.
9.10 Implementation of Scheduling softwareA detailed workshop cum interactive session with all stakeholders was held at WRLDC

9.11 Availability of Real time data involving old RTU / Communication equipment
DGM, WRLDC informed that availability of real time data is very critical now consideringthe complex nature of grid operation, renewable penetration and introduction of Ancillaryservice. Also Hon'ble CERC has directed all users vide order dt 26.9.2012 on petition no194/MP/2011 to ensure availability of reliable real time data at WRLDC as under.Quote
We also observe that many State Transmission Utilities, State Power Departments /Electricity Departments have not responded to our directions to submit a clear cutaction plan for the establishment of the communication system for the existingsystem and the time schedule for completion includingthe provisioning for integration of new generating stations and the sub-stationscoming in future.Un quote
During the 19th SCADA/EMS meeting held on 27th April 2016 at Bhopal, it was emergedthat part of data interruption is due to technological obsolescence and old equipments inoperation. Some of the ULDC equipments (RTUs & communication equipments) have
