Title: Minutes of the MeetingNumber: 508Name of meeting: Operation & Coordination sub-CommitteeDate & venue: 14th June, 2018 at WRPC, Mumbai.

508th meeting of Operation & Co-ordination sub-Committee (OCC) of Western

Regional Power Committee (WRPC) was held on 14th June, 2018 at WRPC,

Mumbai. The list of participants is enclosed at Annexure-A.

Member Secretary (MS), WRPC extended warm welcome to all the participants of

the 508th OCC meeting. He informed the forum about some of the important

operational highlights of WR grid during month of May, 2018:

MS, WRPC informed that power scenario during the last month was

satisfactory, except last week of the May month during which wherein

approximately 1200 MW load shedding was observed in Gujarat system

due to 2000MW increase in summer peak demand.

He expected good monsoon this year & hope for more hydro generation.

He informed that frequency remained within IEGC band for 70.06% of the

time only and 22.52% of the time frequency is below 49.90 Hz. He further

stated that increase in % of time frequency below 49.9 Hz might be due

increase in summer load and reduced availability of generation..

He informed that peak shortage of WR was recorded as 1399MW during

the last month and under interregional exchange, WR exported 6312

MUs to other regions.

He appreciated the efforts by all constituents for maintaining the grid

discipline in WR despite less availability of generation due to many

reasons.


He informed that there are no major grid disturbance events in WR and

he appreciated WRLDC for maintaining the operation of grid within the

limits of various parameters..

He mentioned about “Mechanism for implementation of new

environmental norms for thermal power plants supplying power to

distribution licensees under long term and medium term power

purchasing agreements” under which MoP assigned the task to Hon’ble

CERC for framing the guidelines for addressing the compensation for

installing the FGD.

He informed that “Draft amendments relating to captive power plants in

Electricity rules-2005” is available in MoP website for comments and

requested all utilities for submitting comments, if any, by 18th June 2018.

He also informed that “Proposed amendment to tariff policy-2016” draft

amendments are available in MoP website for comments up to 20th June

2018.

He announced that SLDC Gujarat brought out the “Annual Report”

summarizing all important aspects of Gujarat power system and

congratulated Chief Engineer, SLDC Gujarat for their efforts in preparing

the document.

After the opening remarks, the agenda items were taken up for discussion by

Superintending Engineer (Opn), WRPC.

█ Item no. 1: Confirmation of the MinutesMinutes of 507th meeting of Operation & Coordination Sub-Committee (OCC) of

WRPC held on 15th May, 2018 at WRPC Mumbai were forwarded vide letter No.

WRPC/OPN/OCC-Minutes/2018-19/4720 dated 28.05.2018.

OCC discussed a comment received from ED, SLDC, Chhattishgarh for inclusion

in the MoM and opined that the since addition wanted by SLDC Chhattishgarh

was not a part of discussion in 507th OCC and therefore the request of CSPTCL

cannot be acceded.

Sub-Committee confirmed the Minutes of 507thOCC without any modifications.


█ Item no. 2: Review of System Operation during the month of May, 2018.2.1 A. Frequency Particulars (May 2018)

The frequency profile for last three months was as under:

Discussions:

SE (Opn.), WRPC informed the statistics of frequency recorded during the

month of May 2018. The frequency particulars are enclosed at Annex-2.1.

Chief engineer, SLDC Gujarat expressed concern about frequency touching to

49.57 Hz. He said that that no defense mechanism is available up to 49.2 Hz

due to which there was no AULF operation even when the grid was being

operated at a very alarming condition. It is very difficult for system operator to

manage the grid without any help of automatic load shedding. He further stated

that first AULFS stage must be set at least 49.5 or 49.6 Hz with appropriate

quantum of load shedding instead of 49.4 Hz as agreed during AULFS meeting.

He informed that they operated Gujarat power grid without any reserve in the

month of May, 2018.

MP SLDC representative stated that as frequency is same in integrated grid

operation, the load relief implemented should be implemented proportional in

all regions of India.

Average 49.95 Hz


Gujarat SLDC representative suggested that load relief mechanism implemented

at 49.6 Hz may be designed such that frequency should rise by 0.1 Hz to 49.7

Hz after load shedding. He stated that, All India power number is around 9000-

10000 MW, load shedding required for increasing frequency by 0.1Hz will be

1000 MW when divided between states it will be less than 50 MW.

SE (Opn.) informed that during special meeting of AULFS on 13.4.2018 held at

WRPC it was agreed to increase first stage setting to 49.4 Hz with the same

State-wise quantum of load shedding and therefore the quantum of load

shedding will be decided by NPC after studying the proposals received from

different regions. He further informed that the matter is under consideration of

NPC and the same would be deliberated thoroughly in upcoming NPC meeting

before taking any decision with regard to stages and State-wise quantum of load

shedding.

Representative from WRLDC informed as below:

The minimum frequency during the month of May’18 was 49.57 HZ

during which Maharashtra was over drawing in Western Region.

Section 7.1 of CERC (Deviation Settlement Mechanism and related

matters) Regulations, 2014 mandates that no over drawal of electricity by

any buyer shall be permissible when grid frequency is “below 49.70 HZ”

All states are informed to initiate the actions immediately through load

shedding/increase the intrastate generation when the frequency touches

49.90HZ.

GM, WRLDC opined that there shall be margin available with all the states for

contingencies and if frequency is going downward it will be better to pick up

from available margin. He further informed that system operators shall initiate

actions at 49.9 Hz downwards itself.

SE(Opn),WRPC informed that NPC vide its letter dated 30.05.2018 has given

two options for UFR operation considering power number of 7000 MW.

Option 1: Increasing the State-wise quantum of load shedding by keeping the

frequency slabs same. i.e. 49.2, 49.0, 48.8 and 48.6 Hz.


Option 2: Increasing the quantum of load shedding and frequency slabs of

operation of UFR setting. i.e at 49.4, 49.2, 49.0, 48.8 Hz.

However, in that letter, NPC welcomed any different principle for computation of

load relief by RPCs/NLDC.

The Sub-Committee noted as above.

2.1 B. State wise Power Scenarios’ of the Region & PSP

System operation during the month of May 2018 was satisfactory. The regionaldemand (Ex-bus) was 53817 MW. The corresponding peak shortfall was in therange of 1399 MW (peak deficit of 2.60 %). The energy requirement during thesaid period was 35134 MUs (Ex-bus).The power supply position for the month of May 2018 was as follows:

Discussions:SE (Opn.) requested CE,SLDC Gujarat to inform the OCC forum the reasons for1198 MW load shedding done by Gujarat during last month.

CE,SLDC Gujarat informed that power shortage occurred in Gujarat due topersistent high demand, non availability of large generator, non availability ofpower in bilateral market, non availability of central sector generator for which PPAlinked, non availability of KAPS power.

SE (Opn.) enquired with Mauda TPS representative for under generation of MaudaTPS.

Mauda TPS representative informed that less generation is due to coal shortage inMauda plant. He informed that due to logistical issues with railways the plant isnot getting full supply of coal and management is taking up this issue withrailways. He also informed that wagon tipplers have developed cracks due to whichunloading of coal became difficult. He hoped that power situation at Mauda TPSwill be improved by 22nd June 2018.

MS,WRPC enquired why coal shortage is present with pithead plants of NTPC.

NTPC Sipat representative informed that plant is receiving less coal from minesthan requirement leading to coal shortage.

MS,WRPC enquired with CGPL representative about unit#10 forced outage.

CGPL representative informed that steam from gland of HP turbine was coming outwhich necessitated forced outage of unit#10.

SE(Opn.) requested CGPL to make available URS power to WR needy States incases when NR beneficiaries don’t need power and they give their approval forsupply of power to WR states. He also requested CGPL to revive unit# 50 at theearliest so that the WR States in general and Gujarat in particular can easily meetthe demand with supply.

WRPC requested to update the status of revival of KAPS unit 1 & 2. Representativefrom NPCIL informed that KAPS unit 1 & 2 will be expected to revive in the monthof October 2018 & June 2019 respectively.

In view of the power shortage faced by the states, WRPC and WRLDC requested allthe central sector and State generators to pick up generation available with themwhen frequency falls below 49.90 Hz.

WRPC and WRLDC also requested all states to take corrective measures whenfrequency falls below 49.90Hz.


2.1 Inter-Regional Exchanges (May-2018)There was a net inter-regional export of 6312 MUs from WR to other regionsagainst net export schedule of 6236 MUs.

2.3 Voltage ProfileVoltage profile at some of 765/400 kV sub-stations furnished by WRLDC

is enclosed at Annexure-2.3.

Discussion:OCC forum discussed about high voltages at Dhule substation. Chief

Engineer. SLDC Maharashtra informed that vendor is not supporting forreviving the 2x50MVAR bus reactors at Dhule substation, A new bus reactor of125 MVAR will be coming into service by July 2018.Representative from WRLDC stated as below

Reverse reactive power flow (i.e from LV side to HV side) is observed at

Karad (MSETCL) and Kolhapur (MSETCL) even when the voltages in the

system are high which leads to further increase in system voltages.

The reactive energy from wind stations is injected into system irrespective

of the system voltages in Maharashtra in compliance to their SERC

regulations. In view of this, Maharashtra is suggested to take up the

matter with their SERC for regulatory changes so that wind stations will

absorb the MVAR during high voltage condition.

Generators also have to contribute in controlling high voltage by

absorbing MVAR during high voltage or at least by not injecting MVAR by

maintaining unity pf.

OCC forum requested SLDCs to advise all DISCOMs and wind generators tocontrol MVAR flow to HV side at the time of High voltage.



2.4 U/F Relay OperationsAs per WRLDC records the system frequency didn’t reach 49.2 Hz and no

UFR operation was reported to WRLDC.

Parli unit 6 will be taken out for AOH from 01.07.2018 instead ofproposed unit no. 7. JSW unit no. 2 will be taken out from 01st august 2018against scheduled date of 1st July 2018.

Representative of NTPC Vindhyachal informed that unit no. 12 will be taken outfrom 27th July to 20th August 2018 against scheduled outage from 1st July 2018.He also requested for outage of unit no. 8 from 19th June to 28th July 2018 forwhich OCC consented.

Representative of NTPC Solapur informed that unit no. 1 will be taken outage from31st July 2018 to 20th August 2018 against scheduled date of 26th June 2018.



3.2 Outage programme of Transmission Lines/Elements.List of proposals for transmission elements outage to be availed during the

month of July 2018 is given in Annex 3.2.

WRPC opined that for planning the outages of transmission elements, completeinformation about the elements is essential. It was also felt that some of theagencies are not properly describing the name of elements, due to which lot ofdifficulty is being faced for considering outages. Outages planning group alsoopined the followings:

1. In order to reduce the post OCC outage proposals, regular outages periodfor the consideration of OCC and its approval should be from fifth dayfrom the date of OCC to the last day of next calendar month basis (i.e.D+5+ Next complete calendar Month, where D is date of OCC meeting).For example, If OCC is conducted on 16th June, then outage proposalswill be discussed for the period from 21st June to 31st July ( on an average40 days approximately).

2. The above procedure should be implemented with effect from July 2018month OCC(i.e. planning for outages for the period consisting some partof July & complete August 2018)

3. If above procedure is implemented, then there would be some overlappingperiod for which outages might have already been approved in previousOCC and therefore review of these previous OCC approved outages shouldbe done in current OCC.

4. Two Separate lists of outage proposal would be prepared. First list wouldcomprise regular outage whereas second list would comprise list ofoutages to be reviewed in OCC.

5. Transmission element outage which have been planned shall be adheredto by all the concern entities.

6. Post–OCC outages shall be minimised for better grid operation.7. The transmission licensees shall propose clearly the name of the elements

describing its name and transmission agency, particulars of the elementin detail and reason for outage in detail, else it will not be consideredduring planning of outages.

8. If OCC approved outage of elements are not availed and deferred byconcerned transmission agency during the last two months, this outageshall not be considered in next two month planning provided element isdeferred for system constraints. Post-OCC outages plan shall be on D-5basis only.

9. Sometimes outages for a particular element is requested by the agenciesother than the owner of these elements. It is therefore to be noted thatonly Owner of transmission elements are entitled to request outages oftheir elements. If request is made by other entity, the same shall bedenied.

10. The Outages planning group agreed the same.


Discussions:In addition to outage planning for July 2017, additional OCC outages for

the month of June 2017 were also discussed in the meeting. This was discussedto reduce the post OCC outages proposals. However, the outages approved by507th OCC meeting for June 2018 month will be the first priority in the outageplan. The practice will be continued for next month onwards.

The Sub-Committee noted and agreed as above.

3.3 Anticipated power supply position for the months –June & July2018Details of anticipated restricted & un-restricted demands for the months ofJune & July 2018 are given in Annex 3.3.

Maharashtra, Gujarat, MP & Chhattisgarh updated the anticipated data.

on time.


█ Item No. 7: Status of completion of ongoing schemes in WR7.1 Status of Commissioning of Reactors

7.2 Status of Transmission schemes - 765/400 kV and above7.3 Status of Commissioning of new Generating units in WR

The updated status of above items is at Annexure-7.

The Sub-Committee noted the above information.

█ Item no. 8: Miscellaneous Operational Items8.1: Quarterly review of Crisis Management Plan (CMP) and Physical &

Cyber Security (P&CS) in power sectorAll constituents are requested to submit current status of CMP and P&CS

report (constituent wise) for the Fourth quarter (January to March 2018) as performat enclosed at Annexure-8.1.Discussions:

The forum requested all other constituents to submit the reports positively

and timely.

Sub-committee noted and agreed as above.

8.2: Monitoring of Schemes funded from PSDFAs per the decision taken in NPC meetings, RPC may follow up with the

utilities regularly in OCC to expedite the completion of various approvedschemes by giving due priority. Accordingly, WRPC has been taking up thisissue in OCC forum for discussion.

In this matter, the details related to State-wise sanctioned grant anddisbursement amount for the approved schemes to be funded from PSDF isattached at Annexure-8.2A.

Also, as per the procedure, the utilities are required to furnish theinformation in the prescribed format by first week of every month on regularbasis to Member Convener, PSDF project monitoring group (AGM, NLDC,


POSOCO) with a copy to NPC & WRPC division. A copy of prescribed format isattached at Annexure–8.2B.

Discussions:The utilities were requested to update the current status of progress of scheme

under PSDF.

The Sub-committee noted as above.

8.3 State-wise details for Installation of capacitors to befurnished to WRPCIn accordance with provision in clause 1.5 (ii) of IEGC, “RPC shall file

monthly report on installation of capacitors by states vis-a-vis the

requirement/targets, as decided in the RPC”

SLDC’s /DISCOMs are therefore requested to expedite the matter and

ensure to furnish the status of capacitor report in format attached at Annexure8.3 on monthly basis regularly. SLDC’s are also requested to compile the detailsof various utilities and send the compiled report of entire state by 8th day of

every month.

The Sub-Committee noted and agreed to furnish the same.

8.4 Review of LILO arrangement of 400 KV CGPL - Chorania atBhachau and Power order on ± 500 KV HVDC Mundra -Mohindergadh line:

Chief Engineer, SLDC Gujarat vide email dated 07/06/2018 informedthat, at present, generation at various nodes in Gujarat is as under:

APL, Mundra on 400 KV Bus 1500

APL, Mundra on 220 KV Bus Zero MW

CGPL, Mundra 3000 MW

EPGL, Vadinar Zero MW

Wind generation in Kutch 700 to 800 MW

Power order on HVDC Mundra –Mohindergadh bipolar:

More than APL generation


He informed that under such conditions, the loading on 400 KV D/C

Bhachau - Varsana line remains @ 500 MW in each circuit. To control loading

on 400 KV D/C Bhachau – Varsana line, 400 KV Varsana – Kansari or 400 KV

Varsana – Hadala line keeps open frequently.

In order to avoid above situation, CE, SLDC Gujarat suggested that

the LILO arrangement of 400 KV CGPL – Chorania line at Bhachau to be

removed to reduce injection at Bhachau node OR the power order on ± 500 KV

HVDC Mundra - Mohindergadh line to be kept below generation at APL, Mundra

complex.

Discussions:CE, SLDC Gujarat briefed OCC forum that under the conditions stated in the

above table, frequent opening of STU lines is occurring. In order to avoid this

condition, one of the CGPL-Bhachau line may be connected directly at

Chorania. He informed that STU lines are being opened frequently because of

constraints in CTU network. He also informed that availing of outages at

Bhachau and Varsana substations are becoming difficult in the present

scenario.

Representative from WRLDC stated as below

Studies have been already carried out to review bypassing of LILO

arrangement of 400kV CGPL-Chorania at Bhachau. It is observed from

the studies that there is very less impact of bypassing LILO arrangement

at Bhachau on the loading of 400kV D/C Bhachau-Varsana D/C line. The

results were already shared with SLDC Gujarat. Further, less generation

at APL and Bachhau-Versana being very short line is the main reason for

overloading.

In the real time grid operation, the LILO has helped to reduce the loading

on CGPL-Bachhau lines during full generation at CGPL and no generation

backing down is required for single ckt outage from CGPL. SPS at CGPL

as suggested by WRLDC in 132nd PCM( removal of SPS for single ckt

outage of Bachhau lines and double ckt outage of Jetpur lines) is also

implemented by CGPL.


400 KV Varsana – Kansari or 400 kV Varsana – Hadala linesare not being

opened frequently to control the loading on 400kV D/C Bhachau-Varsana

line except for extreme contingencies. In May 18, CGPL generation was

around 3000MW and APL generation also picked up around 1200-

1800MW, therefore Bachhau-Versana loadings were normal.

During the month of June’18 (up to 14/06/18), 400kV Varsana-Kansari

was opened only once (08:22 hrs of 05.06.18 to 11:02 hrs of 07.06.18)

when HVDC Mundra-Mohindragarh flow was increased when there were

multiple trippings in the grid due to tower collapse. Due to forced

outages of 765kV Agra-Gwalior-1 ,765kV Satna-Bina-2, 800kV Champa-

Kurukshetra HVDC Pole-2, power flow on Mundra-Mohindergarh-HVDC

Bipole increased for line load controlling on 765kV Satna-Oraiduring

which the maximum power flow on 400kV Bachau-Varsana D/C was

570MW/Ckt.

The power flow pattern of important WR-NR lines, Bachhau-Varsana-D/C

lines and HVDC line flows for the month of May’18 is shown below

MS, WRPC informed that as the plan is approved in SCM, change of network

conditions requires SCM approval.


After long delibration, DGM, WRLDC agreed that 400 KV Varsana – Kansari or

400 kV Varsana – Hadala lines will not be opened regularly to control line

loading, but in case of credible contingency in the grid , appropriate actions will

be taken to ensure grid security .

Decision:(1) WRLDC shall not open 400 KV Varsana – Kansari or 400 kV Varsana –

Hadala lines regularly during normal operation of grid.(2) In case of contingency in the grid, WRLDC shall take appropriate action

including opening of above lines based on real time situation.(3) Status quo shall be maintained for LILO arrangement of 400 KV CGPL -

Chorania at BhachauThe Sub-Committee noted the same.

Discussion:

SE(opn.) briefed the OCC forum about the request made by M/s PGCIL and asked

AGM(Commercial), PGCIL for additional clarifications.

1. Whether Conversion of line reactor into switchable line reactor is eligible for

additional RoE?

2. Whether the time line of 36 month for carrying out the work listed at sr. no.

1 is in line with the regulations?

3. PGCIL may furnish details of discussion with regard to planning of the

elements in SCM PGCIL representative replied that all the elements

mentioned at sr. No. 1 to 3 are part of Inter-Regional System strengthening

scheme in WR and NR (Part-B). He stated that the time line given against

element at sr. No. 1 is actually a time line for a transmission line given in

regulation. During discussion, CE, SLDC Gujarat and CE, SLDC

Maharashtra agreed that the commissioning of all the elements mentioned

above have definitely benefitted the system operation in the regional grid

however they expressed their disagreement on 36 month time line for

element at sr. No. 1 (for conversion of line reactor into switchable line

reactor). They jointly stated that the work of conversion of line reactor into

switchable line reactor need very little time and expressed concern about the

timeline of Sr No.1 and requested to review the timeframe.

SLDC MP representative said that Element at Sr No.1 does not qualify for RoE.

WRLDC representative informed that:

1. Switchable line reactor isolates the reactor in case of fault in reactor andline tripping will be avoided.

2. Due to the commissioning of Jabalpur Orai double ckts along with linereactors, ATC and TTC of WR to NR increased.

3. Due to the LILOing of Satna-Gwalior at Orai S/s, loading of Gwalior-Agralines has been reduced substantially.

After long discussion, all states agreed that the elements at sr. No. 2 and 3 are

beneficial for system operation in the regional grid may qualify for additional

RoE.


At the end of discussion, the following decision were taken:

(1) PGCIL & WRLDC shall prepare list of benefits due to early commissioningof all the three elements which are under consideration for additionalROE in accordance with the regulation.

(2) WRLDC shall explain the listed benefits due to early commissioning of allthe three elements to the forum in the next OCC meeting.

3. MVAR absorption by Generating station to control high voltageEven after taking Bus Reactors, Line Reactors, Switchable Shunt Reactors inservice and opening lightly loaded lines, high voltages are observed at most ofthe EHV nodes during night hours. In view of inadequate shunt reactivecompensation, the generating units are being advised to contribute in voltageregulation by operating their units in under-excited mode (absorb ReactivePower) within the capability curve. The MW, MVAR and Voltage of generatingunits was analyzed for the month of May 18 with the help of SCADA dataavailable at WRLDC. The list of generators injecting MVAR into the grid evenwhen the bus voltage is above nominal are given below.

5. Tripping of Kalwa(MSETCL) 400/220kV ICT-2 at 01:02hrs of 01.06.18400/220kV ICT-2 (600MVA) at Kalwa tripped at 01:02hrs of 01.06.18 due tooperation of PRV and differential protection. Subsequently, 400/220kV ICT-1(500MVA) at Kalwa was hand tripped at 01:30hrs of 01.06.18 to avoid thespreading of fire from ICT-2.Due to this, load trimming scheme was operated and load was effected to a partof Navi Mumbai and Mulund. Load loss of around 304 MW was reported byMaharashtra. Subsequently, the damaged cables were replaced with new cablesand the ICT-1 was charged on 03.06.18 at 13:42 hrs.


Further, the telemetry data of 220kV Maharashtra system is not available atWRLDC, due to which the assessment of real time conditions in the affectedarea is not possible.In view of the above, Maharashtra is requested to expedite the restoration of400/220kV ICT-2 (600MVA) at Kalwa and take necessary actions to make220kV telemetry data available at WRLDC.

SLDC, Maharashtra may apprise the OCC regarding the actions taken to controlthe Kalwa ICT loading and the details of load management in Mumbai area inview of above contingency.

Discussions:Maharashtra informed that following actions were taken to control the Kalwa

ICT loading on 01.06.18.

LTS scheme operated and 250MW load relief was obtained

Generation from Tata hydro/gas increased

Ghatghar unit-1 (125MW) taken in service

Maharashtra said that the ICT-IV at Kalwa would be commissioned within 4

months.


6. Constraints in keeping the thermal units on-bar to manage the highdemand in day time and less demand during off peak hours

It was observed that, due to bad weather condition and rains, the demand inWestern Region during off peaks hours was less and the demand in day timewas considerably high. Due to less demand in off peak hours, the states weresurrendering their share in IGGS generators, leading to the condition of belowtechnical minimum schedule in some ISGS thermal generators. It is observedduring last week that the difference in WR maximum demand to minimumdemand is ranging from 5000MW to 6500MW. In order to meet the highdemand in day time, the thermal generating stations for which schedule isbelow technical minimum are supported up to technical minimum. Thevariation in WR demand for a typical day (02/06/18) is shown below.


All states are requested to stagger their load to avoid the condition of technicalminimum in thermal stations during off peak hours in view of high anticipateddemand in day time.

Discussions:WRLDC informed all states to stagger their load and give the requisition to avoid

the condition of below technical minimum in thermal stations during off peak

hours in view of high anticipated demand in day time.


7. Delayed/Non submission of DR for grid eventsThe utilities need to submit the DR/EL details for Grid events to RLDC within24 hours of occurrence as per IEGC 5.2(r).The non-submission /delayedsubmission of details from utilities lead to delay in detailed analysis of theevent. For the events DR/EL is still pending is attached at Annexure 9.7:Discussions:All the concerned utilities mentioned above are informed to submit the DR/ER

by 18/06/18 and comply IEGC 5.2(r) for future grid events.





















8. Grid Occurrence on 03rd June 2018 at ACBIL Power station due to Badweather conditions

On 03rd June 2018 at 16:22 Hrs, 400 kV MCCPL- Bilaspur tripped. Further at16:26Hrs 400 kV ACBIL-MCCPL and 400 kV ACBIL-Bilaspur tripped. Thisresulted in tripping of all the generators in both the power station due to loss ofevacuation path and led to a loss of 654 MW generation. The list of elementstripped are given below:-

Maharashtra informed that the black start mock drill exercise of Koyna isplanned in the last week of June’18. The exact date would be communicated toWRLDC once it is finalized.


12. Follow-up of agenda items discussed in past OCC meetingi. Installation of PMU for observability of dynamic performance of

STATCOMsFor dynamic reactive VAR compensation in Western Region, fourSTATCOM’s were approved in 36th SCM of WR. In order to monitor thedynamic performance of the STATCOM+ MSR / MSC, it is desired toinstall PMUs at STATCOM locations (SATNA PG, Gwalior PG, AurangabadPG and Solapur PG). The matter was already discussed in the 505th, 506thand 507th OCC meeting.

Discussions:POWERGRID informed that the STATCOMs can be integrated with the existing

PMUs by replacing any one of the feeders integrated to PMU.

WRLDC informed that the list of lines to be replaced with STATCOMs for

integration with existing PMUs would be forwarded to POWERGRID.


ii. Synchronous Condenser Mode of Operation at GhatgharDuring 505th& 506thOCC meeting, WRLDC advised Maharashtra SLDCto explore the possibilities of operating Ghatghar machines insynchronous condenser mode of operation to improve the voltageprofile at 220 kV Ghatghar and 220 kV Kalwa.

Maharashtra SLDC vide its email dated 23.04.18 submitted theconcerns of Ghatgar Hydro Power Stations to operate the machines incondenser mode as given below. Operation in condenser mode requires the continuous water

depression of draft tube. This is achieved by the pressurized airfrom the water depression compressor. These compressors areimported compressors and there are issues in the procurement ofthe spares for these compressors.

There is no mention about the operation of machines in condensermode in the power purchase agreement (PPA). Being a policymatter, the proposal to be put up with higher officials.

During 504th, 506th OCCM and 3rd REIF meeting, WRLDC highlightedthe importance of LVRT to prevent simultaneous loss of generationfrom RES. All SLDCs were informed to compile the information asfollowing.a. Capacity of RES in the State that is exempted from LVRT : Stall

type / Capacity below 500 kWb. Capacity of RES in the State that is mandated to have LVRTc. Capacity of RES in the State that is LVRT compliantd. The present methodology of checking LVRT compliance in vogue for

giving clearance for integrationGujarat and Madhya Pradesh submitted the data during 3rd REIF heldon 17.04.18.

Discussions:Maharashtra informed that the required inputs has been sent to WRLDC

on 13/06/18.

WRLDC informed that the inputs received would be verified and updated.



iv. Parallel operation of 220kV Kolhapur_MS(WR)-Chikodi(SR)and220kV Talangade-Chikodi lines with other WR-SR Inter Regionallines220kV Kolhapur_MS(WR)-Chikodi(SR) and 220kV Talangade-Chikodilines are natural interstate line between Maharashtra in WR andKarnataka in SR. These lines are operated in radial mode to supplypower from Maharashtra to Karnataka.During 505th& 506th OCC meeting, WRLDC shared the merits ofutilization of 220kV Kolhapur_MS(WR)-Chikodi(SR) and 220kVTalangade-Chikodi lines for inter-regional power transfer with ISTSstatus.During 507th OCCM, WRPC informed Maharashtra to take up thematter with Maharashtra STU and Karnataka with a copy ofcommunication to WRPC and WRLDC.

Discussions:Maharashtra raised the concerns on overloading on Kolhapur ICTs during

summer.

WRLDC informed that ICT loading was analyzed for last one year and

shared during 505th OCCM in which ICTs loading were normal except few

days. And this ICTs overloading can be addressed by implementing inter

tripping scheme.

Maharashtra requested WRLDC to share the analysis on Kolhapur ICTs to

take up the matter with STU. WRLDC agreed to sharethe study results

with Maharashtra.

Members of OCC suggested that the lines may be taken into operation as

there are constraints only during few months. In case of high loading of

Kolhapur ICTs in any time, the lines can be opened. He requested MSLDC

to take action for parallel operation.
