5. MVAR absorption by Generating station to control high voltage

Even after taking Bus Reactors, Line Reactors, Switchable Shunt Reactorsin service and opening lightly loaded lines, high voltages are observed atmost of the EHV nodes during night hours. In view of inadequate shuntreactive compensation, the generating units are being advised to contributein voltage regulation by operating their units in under-excited mode (absorbReactive Power) within the capability curve. The MW, MVAR and Voltage ofgenerating units was analysed for the month of Nov 18 with the help ofSCADA data available at WRLDC. The list of generators injecting MVAR intothe grid even when the bus voltage is above nominal are given below.


1. IPPs: Essar Mahan, RKM, GMR-CG, Dhariwal, DB Power, Jhabua,

TRN, JPL-I (U#3), JPL Tamnar (U#2, U#4)

2. ISGS: KSTPS (U#3, U#2)

3. Gujarat: Wanakbori (U#4, U#5, U#6 & U#7)

4. Maharashtra: Koradi (U#8 & U#9), Bhuswal (U#4 & U#5);

Khaparkheda (U#5), Chandrapur(U#7)

5. M.P. JP Bina(U#1), Satpura (U#10 & U#11), Singhaji (U#1 & U#2)

All the concerned utilities to update the plan to adjust setting of theAVR / GT tap so as to enable generating units to contribute involtage regulation within capability curve.

6. Voltage Regulation in Western Region

In the month of Dec’18, voltages were above IEGC band at 400 kV Dhule,

Karad, Kalwa, Magarwada, Kasor, Boisar, Raigarh, Wardha and Mapusa.

The Voltage Deviation Index of above nodes are tabulated below.

7. Updating the “Recovery Procedure for Western Regional (WR) Grid –2019”As per sec 5.8 (a) of the Indian Electricity Grid Code, the ‘Western RegionalGrid - Recovery Procedure’ needs to be updated annually by WRLDC inconsultation with the NLDC, WR grid users / STU / SLDC /CTU and theWRPC secretariat. The WR Grid - Recovery Procedure was last updated &published on 31st January 2018. Subsequently there has been addition ofseveral new generation & transmission elements in Western Regional Gridin past one year leading to change in network configuration. Further, blackstart mock drills have been conducted in last one year at power stationshaving black start capability. WRLDC is updating the ‘Grid RecoveryProcedure’ keeping track of the above changes.

The WR utilities may kindly convey the relevant details to WRLDC asunder for facilitating timely updation of this document.

Updated details/status of the following may be conveyed to WRLDC.

1. Contact details (Mobile/ Land line numbers/ Email-ID) of the nodalofficers identified for crisis management.

2. Updated ‘Recovery Procedures’ for respective states prepared by SLDCincluding protocol for operating the backup control center/backupSLDC.

3. List of new transmission elements and generation units commissioned in2018.

5. Traction Supply details6. Synchronizing facilities at 132kV/220 kV/ 400 kV /765 kV sub-stations.7. List of stations having black start capability.8. Any other relevant information for further improving the ‘Grid Recovery

Procedure’.

OCC members may like to discuss


8. Updating the “Reactive Power Resources in Western Region-2019”

Reactive Power Resources in Western Region WR Grid was last updated &published on 29th December 2017. This document contains the details ofthe reactive power resources available for Reactive Power management inWestern Regional Grid. Link is given below.

http://wrldc.org/content/363_1_Procedures.aspx

WR entities may provide the feedback and suggestions for updatingreactive power resource document for the year 2019.

9. Black Start mock drill Exercise in Western Region

As mandated by IEGC, the Black start capable units need to conduct mockblack start exercises once in every 6 months. Western Region has 29generating stations with black start capability. As per the informationavailable with WRLDC, only 10 black Start stations have completed theMock exercise in the year 2018. The proposed tentative schedule updated bySLDCs during last OCC meeting for black start mock drill is given below.

Only few days are left for black start stations for conducting mockdrills and to comply with IEGC regulations.

All SLDCs are requested to furnish black start mock drill reports toWRLDC conducted so far along with availability and status ofsynchronizing trolleys.




















Black start mock drill was conducted in only one station out of 9stations in Maharashtra. SLDC, Kalwa may update status of mock drillsscheduled in Dec’18.SLDC MP, Gujarat and Chhattisgarh may apprise OCC on mock drillsscheduled in month of Dec 18.

10. Deviation from Schedule by CGPL, Mouda and SasanIt has been observed that there is persistent deviation from schedule byCGPL, Sasan and Mouda generating stations. The relevant extract from theweekly DSM account is given below:

The persistent deviation by large generating stations CGPL, Sasan andMouda is causing generation surplus/inadequacy in the grid andaggravating the security threat in the system. The deviation from schedulesby these stations has continued despite messages sent from WRLDC controlroom.

Members may like to deliberate.

11. Tripping of lines due to fog in winter season

Tripping of transmission elements have occurred during the last winter dueto fog in Saurashtra and South Gujarat (Gujarat); Nagda, Rajgarh andIndore (Madhya Pradesh); Satara (Maharashtra) and 220 kV network ofGOA.


The tripping of lines resulted in load loss and generation loss during theprevious years. Gujarat, Madhya Pradesh, Maharashtra and Goa SLDCsmay indicate the measures taken to avoid such trippings and contingencyprocedures developed in case of such tripping.

Following general measures shall also be ensured:

1. The voltages in fog prone areas are to be maintained close to 1.0 p.u.2. At least two alternate paths to each sub-station are to be made

available wherever possible to ensure availability of supply in case oftripping of a line on fog.

3. Generating stations may be instructed to control voltages byabsorbing or injecting VAr.

Members may like to discuss.

Item No. 10: Date and venue of next OCC meeting

The date & venue of 515th OCC meeting will be intimated later on.
