472nd OCCM AGENDA

ITEM NO 8.5: PROCUREMENT OF EMERGENCY RESTORATION SYSTEM FORSUBSTATION AT 400/220/33KV

DGM, WRLDC informed that during 14th WRPC meeting held on 19th Aug, 2010,

POWERGRID proposed for procurement of Emergency restoration System for

Substation at 400/220/33kV level to meet the contingency arising out of natural

calamities like earthquake, flood, cyclone etc. WRPC agreed in principle and suggested

discussion in technical committee meeting to examine the proposal.

The technical committee subsequently discussed the issue and in TCC meeting of 15th

WRPC meeting held on 11th Nov, 2010, members did not agree to the procurement of

ERS Substation at 400kV level in this phase. TCC suggested that the procurement of

ERS of lower voltage level i.e. 220kV, 110kV/132kV could be explored by the constituent

states.

During 16th WRPC meeting held on 12th February, 2011, POWERGRID had clarified that

the ERS Substation can be installed anywhere even below the EHV lines. The units can

cater load at 33kV level upto 33% of the rated capacity of the transformer besides

establishing connectivity over 400/220kV level. However, WRPC did not agree to the

proposal of procurement of ERS Substation.

Recently, cyclones of the scale of Phailin in Odhisha and Hudhud in Vizag caused

enormous damage to Power transmission infrastructure in the respective regions which

triggered revisiting the requirement of ERS Substation at 400/220/33kV level. Matter was

again discussed in TCC meeting of 28th WRPC held on 3rd March, 2015 where TCC

members agreed to the suggestion of MS, WRPC that the earlier view taken by WRPC

about three to four years ago on the ERS substation can be relooked under the present

changed scenario.

During CCM meeting held on 4.06.2015 it was recommended that the proposal for ERS

s/s be discussed first in OCC for technical details and tentative cost estimate. So that

recommendations of OCC could be put up to TCC/WRPC ensuing meeting.

The Sub-Committee may like to discuss the same.

The Sub-committee may like to discuss/note the same.

ITEM NO. 9 : ITEMS FROM WRLDC:

9.1 NEW-SR GRID SEPARATION AND ROUGH SYNCHRONIZATION ON 24-MAY-15 AND 31-MAY-15.

SR Grid separated from NEW Grid on 24-May-15 at 19:19:00 and again on 31-

May-15 at 17:00 hrs.

a) Separation on 24-May-15 at 19:19 hrsSequence of Events as Under

1) 400kV Bhadrawati –Ramagundam-2 tripped at 17:12 hrs, thereby reducing

the flow on HVDC Bhadrawati from 900MW to 600MW.

2) Before the event, multiple units in SR tripped (1534MW) leading to rise in

flow of 765kV Solapur-Raichur-2xS/c from 250MW to 1200MW.

3) Talchar-Kolar Bipole was carrying 2300MW.

4) 500kV HVDC Talcher-Kolar Pole-1 tripped at 19:18:34 and the flow on

765kV Solapur-Raichur-2xS/c increased from 1200MW to 2000MW,

initiating the operation of SPS-1, the flow settled at 1500MW.

11

472nd OCCM AGENDA

5) Tripping of 500kV HVDC Talcher-Kolar Pole-2 at 19:18:50 hrs, the flow on

765kV Solapur-Raichur-2xS/c further increased from 1500MW to above

3000MW, this initiated the operation of SPS-1. After 10 sec of continuous

loading of 1000MW/ckt (current exceed 800 amp) has initiated the operation

of SPS-7 and thereby tripping of both the circuit of 765kV Solapur-Raichur-

2xS/c lines. Both the line disconnected at Raichur(SR) end but remained

connected at Solapur(WR) end.

6) Auto synchronisation facility is available only at Solapur(WR) end. The line

which was connected from Solapur end was disconnected and charged

from Raichur(SR) and subsequently synchronised at Solapur end at 20:48

hrs.

7) It was observed from PMU data that 765kV Solapur-Raichur-1 had a rough

synchronization at Solapur end. The initial power flow on this circuit was

from +3000MW to -3000MW, the current in the circuit has crossed 5000A

and Bus voltage at 765kV Solapur has dipped by 481kV. Further, it was

observed from angular different plot 765kV Solapur Bus and 400kV Raichur

Bus was more than 50 degrees at the time of synchronization.

b) Separation on 31-May at 17:00 hrs

There was bad weather and heavy rain. The 765kV Solapur-Raichur-II tripped

at 16:58hrs on B-ph to earth fault, subsequently 765kV Solapur-Raichur-I

tripped on Y-ph to earth fault at 17:00 hrs, leading to separation of NEW-SR

Grid.

The 765kV Solapur-Raichur-1 charged from Raichur at 17:42hrs.

Synchronization was done through the tie CB at Solapur end at 19:00 hrs.

There was a power swing of +/- 3000MW was observed which trigged SPS-1

and caused backing down in WR and Load shedding in SR. 765kV Solapur-

Raichur-II was restored at 19:25 hrs. Further analysis revealed that

synchronization command was given at angular separation of 116 degrees.

Following issues need detailed deliberations and review :1) Rough Synchronization: On 24-May synchronization was done at angular

separation of around 50 degrees, while on 31-May the synchronization was

12

472nd OCCM AGENDA

done at 116 degrees. POWERGRID may confirm the Protocol and settings

adopted for synchronization.

2) Healthiness and correctness of System Protection Scheme along withcommunication system: The tripping of Solapur –Raichur on 24-Mayoccurred due to triggering of SPS-7 at Raichur end. This SPS-7 was

supposed to be blocked when both the lines are in service.( Ref:-

POSOCO/NLDC/System Operation/SPS/472 dt 7th July’14). The SPS-7 was

supposed to be armed, when only one circuit of Solapur-Raichur is in

Service [Trip the 765kV Solapur-Raichur line with delay of 10 sec, when

single line carrying more than 1000MW (800 amp)]. POWERGRID may

confirm the setting of SPS-7 adopted at Raichur and Solapur end.

Healthiness of auto-synchronizing facility: Normally 765kV Solapur-Raichur-2xS/c is synchronised at Solapur end. Auto synchronization facility

is configured only at Solapur (WR) end. The auto synchronization facility

was not working at Solapur (WR) during this crisis situation. On 24-May-15

Synchronization could be done after 1hrs 29 minutes, while on 31-May it

took 2hrs. POWERGRID may confirm the healthiness of auto-synchronizing

facility and capability to synchronize through any of the breakers at Solapur

as well as Raichur. This may help the system for early restoration during

such crisis condition.

3) Inadequate response from envisaged generators during SPS-1operation on 765kV Solapur-Raichur-D/c as evident from the table below.

Mock Blackstart drill of Hasdeo Bango was successfully conducted on 17-May 2015.

SLDC Chattisgarh may update regarding commissioning of RTU at Hasdeo Bango

and healthiness of communication system to restore telemetry from Korba (E).

NCA had proposed to carryout Blacktstart exercise of one unit of RBPH by extending

supply to a thermal unit in Gujarat (say Wanakbori / Ukai TPS). A meeting was

proposed for finalizing the procedure. NCA / SLDC

Gujarat may update the progress.

9.4CONSTRAINTS IN GRID OPERATION DUE TO NON-AVAILABILITY OFTELEMETRY FROM MSETCL/MAHAGENCO STATIONS

Non-availability of telemetry from large number of EHV stations of MSETCL and

Mahagenco has been flagged by WRLDC and is being deliberated in the OCC forum

for more than a year. There are nearly 22 stations like 400 kV Warora, Chandrapur2,

Bhusawal, Lonikhand and Taptithanda where the integration of database is pending

17

472nd OCCM AGENDA

even several months after commissioning of the substations and there are nearly 48

stations where database integration is completed but data from these station is highly

intermittent due to continuous failure of communication link.

In the absence of telemetry from these stations, severe constraints are being

experienced by WRLDC control room personnel in real-time supervision and operation

of the grid.

Further, it was stated by MSETCL in 470th OCC held at Lucknow that all telemetry

issues related to Maharashtra shall be sorted out by the month of May-15.

MSETCL may apprise the progress.

9.5 ADMS(AUTOMATIC DEMAND MANAGEMENT SCHEME) IMPLEMENTATIONAS PER SEC. 5.4.2 OF IEGC:As per the Hon’ble CERC’s order, WRLDC is monitoring the implementation of ADMS

in Western Region. As per the information received from all constituents, progress of

implementation of ADMS is as follows.

Gujarat: ADMS in Gujarat has been implemented with all respects in all fourState Discoms as per letter dated 7th May,2015. Approximately 30 to 40 MW loadrelief is envisaged from over drawing Discom when average frequency remains below

49.80 Hz for 10 minutes and State over drawal is more than 150 MW and Discom’s

over drawal is more than 50 MW.

Maharashtra: Completion target is 2nd quarter of 2015 as per information receivedon January, 2015. Progress of implementation has not been furnished.

Madhya Pradesh: Completion target is 3rd/4th quarter of 2015 as per the progressreport received 31.01.2015. No progress of implementation has been furnished

Chhattisgarh. Committee has been formed for implementation of ADMS. Target forproject completion is Q4 of 15-16 as per letter 20.03.2015. Further progress is not

been informed.

9.5TELEMETRY AND AVAILABILITY OF DATA FROM RES FROM STATES INWR.

Renewable Energy installed capacity is 10225 MW, which is 12% of total installed

capacity in Western Region. This include Wind installed capacity of 8517 MW and

Solar installed capacity of 1708 MW. The installed capacity state vice is given in below

table.

SCADA telemetry data is available from Gujarat only, where only net Gujarat solar

generation and net Gujarat wind generation are displayed in real time. The station vice

generation from different solar and wind plant are not available in WRLDC SCADA.

SCADA telemetry from renewable generation of Maharashtra and Madhya Pradesh

are also not available at WRLDC.

Station level SCADA telemetry may be facilitated for correct computation of Net State

generation, State demand met and the impact of renewable generation in real time.

Concerned utilities are requested to arrange for availability of SCADA data at WRLDC.

9.6SUBMISSION OF LOAD/GENERATION LOSS DETAILS DURING ANY GRIDINCIDENTS/DISTURBANCE

Any Grid events is to be reported to NLDC and WRPC at the earliest with the

Category of the Grid Incident or Grid Disturbance. The Category of Grid Incident or

Grid Disturbance are computed by the percentage loss of antecedent Generation or

Load, whichever is higher, in a regional Grid. The Category indicate the severity of the

Grid Incident or Disturbance.

It has been observed that many of the utilities are not submitting the Generation/ Load

Loss details, which is hampering in calculating the correct Category of GD/GI.

So, as an interim measure, WRLDC is calculating an approximate loss in generation

and Load, both in MW and MU, based on its SCADA data. The logic used for

computation is based on three parameters i.e. Demand Reduction, Drawal reduction,

and Power number. The energy unserved is being calculated from the area under the

demand met curve from the starting of event till its restoration, when compared with

previous day demand met curve for the subjected utility from WRLDC SCADA.

19

472nd OCCM AGENDA

Hence, it requested from all utilities to send the detail at the earliest, about the

Generation/Load loss quantum (MW and MUs) with supporting document from their

SCADA or site.

The sub-committee like to discuss the same.

ITEM NO. 10: DATE AND VENUE OF NEXT OCC MEETING471st OCC reviewed the meeting roaster and finalized sheet is enclosed at Annexure-

10. Accordingly, as per roster, it is proposed to host 473rd by TATA Power in the

month of July 2015. The tentative date for 473rd OCC meeting is 14th July 2015. TATA

Power may intimate the exact venue details etc.

Further as per roster 474th OCC meeting would be hosted by M/s Jindal Power Ltd in

the month of August 2015.
