of 01.04.18 due to failure of auxiliary power supply as reported by

POWERGRID. It is understood that there are three sources of auxiliary

supply for HVDC Bhadrawati

1. 33kV lines of Maharashtra Discom.

2. 33kV tertiary of 250 MVA, 400/220/33kV ICT (recently shifted

from Moga).

3. Diesel Generator set.

Existing 250MVA ICT (shifted from Moga of NR) was charged on 06th

Sep’17 in place of 315 MVA ICT. However the 400/220/33kV ICT at

Bhadrawati is out of service since 25.02.18 due to LV side bushing oil

leakage. In case of failure of primary source and non-availability of

secondary source, the DG supply should have come in to service

5. Emergency outage on 765kV Vindhyachal PS-Satna-1 andoscillations in frequency at the time of shutdownEmergency outage on 765kV Vindhyachal PS-Satna-1 for attending top

phase open jumper conductor problem at location no. 542 (as intimated

by Powergrid) was availed by Powergrid on 02.04.18 at 20:37 hrs. Total

generation of Sasan (around 4000MW) and VSTSP-IV& Rihand-III

(around 2000MW) is evacuated through 765kV Sasan-Satna D/C and

765kV Sasan-Vindhyacha PS-Satna only. Outage of any transmission

line in this corridor requires generation back down at Sasan, VSTPS-IV &

Rihand-III. Therefore in order to facilitate the emergency outage on

765kV Vindhyachal PS-Satna line-1, generation back down of 800 MW

was implemented in Sasan, VSTPS-IV & Rihand-III. Also the tie lines

between VSTPS-IV and VSTPS-V were closed to control the loading on

765kV Vindhyachal PS-Satna-2.Main breakers of 400kV VSTPS-Sasan

and 400kV REWA-Sasan were also closed prior to emergency outage.

Oscillations in frequency of Satna PMU for about 5 seconds were

observed during the shutdown of 765kV Vindhyacha PS-Satna line-1 on

02.04.18.The oscillations in the frequency of Satna, Vindhyachal_PS,

Bina_PG and VSTPS PMUs is shown below.

6. Installation of PMU for observability of dynamic performance ofSTATCOMsFor dynamic reactive VAR compensation in Western Region, four

STATCOM’s were approved in 36th SCM of WR. In order to monitor the

dynamic performance of the STATCOM+ MSR / MSC, it is desired to

install PMUs at STATCOM locations (SATNA PG, Gwalior PG,

Aurangabad PG and Solapur PG). The matter was already discussed in

the 505th OCC meeting. The communication from WRLDC in this regard

sent to WRTS-I & II, POWERGRID is enclosed as Annex-9.6.

POWERGRID may like to update the progress in this regard.

7. Automatic Generation Control (AGC) pilot project at NTPC Mouda.A meeting to discuss the implementation of AGC at NTPC Barh,

Simhadri, Bongaigaon and Mouda was held at NLDC on 27th March

2018. Representatives from respective NTPC stations, NTPC WRHQ and

WRLDC also participated. The MOM is enclosed as Annex-9.7). The

highlights of the meetings are as below.

i. NTPC confirmed that their units are compliant of accepting the set

points in NTPC Dadri model

ii. It was decided that a joint survey will be made by RLDCs / NLDC

and POWERGRID at the RLDC and the power plant to identify the

communication requirements

iii. Considering the compatibility and integration issue with NLDC

software (procured through M/S Siemens on limited tender basis

during first pilot project at Dadri Stage-II) and the experience of

implementation, it was proposed/suggested to award the tender to

M/S Siemens for smooth implementation of the pilot projects in all

the five regions. It was discussed that since this is a pilot project

and expeditious commissioning is necessary, procurement may be

done on single tender basis. After the discussions NTPC agreed to

take up with M/S Siemens regarding the survey and requirements.

506th OCC AGENDA

iv. It was also decided that a local survey will be made by Mouda and

will send the requirements to M/S Siemens

8. Assessment of Total Import Capability of Gujarat Control AreaWith the commissioning of various transmission elements and the

present skewed dispatch scenario of very less generation at APL

(4x330+6x660 MW), NIL generation at Essar Vadinar (2x600 MW), CGPL

one unit out, total import capability of Gujarat system is re-assessed for

various contingencies. As per the Mar’18 peak case scenario studied, it

was observed that with Gujarat demand of 15000 MW State generation of

around 6600 MW, the system is secure if the Gujarat drawl from ISTS is

maintained within 8800 MW. The limiting constraints is N-1 contingency

of 765/400kV 2x1500MVA Vadodara ICT.

1. Total Import TTC : 8800 MW

2. Reliability Margin : 300 MW

3. Total Import ATC : 8500

The communication from WRLDC in this regard was sent to SLDC,

Gujarat (Enclosed as Annex-9.8).

For kind intimation of OCC members.
