He stated that in future also the operational issues will be resolved with co-operation of all the entities, if brought in this forum.

Further he stated that the issues included in the MP OCCM are submitted by SLDC itself as per their

observations and no operational issues/agenda points are being submitted by any other entity, which leads to the conclusion that the entities are not having any operational problems/issues. He also stated that JP Bina might have some commercial issues that shall be discussed with MPPMCL separately. Thereafter he requested all the entities to submit the agenda point if they are having any operational issues, so that the grid operation can be made more safe & secure with our combined efforts. He also requested all the generating stations to absorb MVAR from the grid in case of high voltage and MPPTCL shall do the switching operation of reactor. Also MPPTCL with coordination of Discom shall operate the capacitor banks as per system requirement to support the grid.

Thereafter Chairman, OCC requested the Member Secretary to take up the agenda points. Member

Secretary, Shri R.A. Sharma expressed his thanks to JP Bina for conducting the 58th OCCM and all participants on the occasion for participating. He stated that the operational issues as mentioned by Chairman OCC is of great importance for operating the grid in safe & secure manner, however the commercial issues cannot be neglected but those issues can be addressed and discussed. He also stated that the incidences of blackout like the one in 2012 has not yet been resolved and SLDC’s & other concerned entities are being penalized. Hence to avoid such black outs in future and the safe & secure operation of the grid can only be maintained by proper co-ordination & co-operation of the grid entities. Further he requested for a formal introduction of all the participants.

Thereafter Member Secretary, OCC took up the agenda points.

The implementation of most of the schemes are based on the recommendation of the enquiry committee on grid disturbance of July 2012 headed by Chairperson, CEA. Therefore timely implementation of these schemes would enhance the grid security and reliability. Accordingly the details of grant sanctioned from PSDF for the schemes of MP is enclosed at Annexure- 6.5A. The status of implementation of above schemes (physical as well as financial progress) may please be reviewed and the entities are requested to expedite implementation of the schemes. The utilities were advised to furnish the information in the format enclosed at Annexure – 6.5B by first week of every month on regular basis to Member Convener, PSDF project monitoring group (AGM, NLDC, POSOCO) with a copy to NPC, WRPC division and SLDC. The status of the same is being monitored by WRPC in OCC meeting of WRPC every month. It is observed that MPPTCL and MPPGCL are not submitting the requisite information to SLDC in first week of every month for onward transmission to WRPC. It is therefore requested that concerned official may please instructed to submit the same to SLDC with time limit.

The matter was discussed in the meeting & MPPTCL & MPPGCL assured to submit the same within time. 6.6 MVAR absorption by Generating Stations to Control High voltage: It was observed that during the monsoon, demand in WR reduces by 4000-5000 MW. In the past, even after taking all Switchable Shunt Reactors in service and opening lightly loaded lines, high voltages are observed at most of the EHV nodes during night hours. In view of inadequate shunt reactive compensation, the generating units are being advised to contribute in voltage regulation by operating their units in under-excited mode (absorb Reactive Power) within the capability curve. The issue was discussed by WRLDC and SLDC in various OCC meeting and advised generators not to inject reactive power into the grid even when the bus voltage is above nominal. The MW, MVAR and Voltage of generating units was analyzed for the month of May 2017 with the help of SCADA data available at WRLDC and SLDC . it is observed that almost the same generators of MPPGCL are contributing to inject MVAR in to grid even when voltage if above nominal a. Satpura (U#10 & U#11) b. Singhaji (U#1 & U#2) It was observed that almost the same list of generators mentioned in 494th OCCM are continuing to inject MVAR into grid even when voltage is above nominal. SLDC is continuously requesting all the concern generating stations in real time to control high voltage scenario by absorbing MVAR by their generating units. It is therefore requested all concern Generating Stations not to inject MVAR into grid when there is over voltage for safe, secure and reliable operation of the grid. Member Secretary OCC stated that during Monsoons ,due to low demand EHV transmission lines are lightly loaded , resulting in the high system voltages. Hence generating station shall absorb the MVARs as per the capability curve and support the grid. 6.7 REPORTING OF FLASH REPORT, DR and EL FOR 400KV, Interstate Transmission Elements & Detailed Tripping Report:- Member Secretary OCC informed committee that as per the provisions of Regulation 5.2 (r) of CERC (Indian Electricity Grid Code) Regulations 2010 and Regulation of 5(9) of CERC (Indian Electricity Grid Code) (First Amendment) Regulations, 2012 all the Regional Entities of the Region shall furnish the tripping details including DR & SEL output to RLDC with in 24 hrs of the event for analysis and identify the real time measures required in future to ensure secured grid operation. The flash report is also required to be furnished to SLDC within an hour of tripping. It is observed that FLASH REPORT, DR & EL of station is not made available after tripping of transmission grid element by the State Grid Entities and the flash report is also not being sent after repeated pursuation. All intra-state entities are requested to submit the FIR, DR & EL of station during tripping of transmission grid elements.

However, the desired progress in the matter is not observed. The railway representative informed that the tender for the telemetry arrangement is yet to be floated by railway and railway is planning to float tender for providing telemetry of 20 railway TSS and not for all 38 existing TSS. SLDC informed that in view of the existing progress status, the arrangement of telemetry by June 2017 is not yet possible and railway is required to expedite the matter.

Further, MPPTCL representative informed that in addition to existing 38 No. Railway TSS in MP, planning for establishment of around 25 new TSS is also under progress. Thus railway is required to plan for arranging telemetry of all 38 existing TSS as well as for 25 upcoming TSS. Accordingly, SLDC requested railway to expedite the matter and arrange telemetry of all TSS sub stations. Railway officers informed that they will takeup the matter with there management. Minutes of Supplementary Points SA-I Tripping of Indore –ISP feeder at ISP on 09.07.2017 :- Member Secretary OCC informed committee that 400 kV Indore-ISP ckt. II tripped at 19:55 Hrs on dtd. 09/07/17 from ISP end only on the

indication DT received from other end. 400 kV S/s Indore of MPPTCL has intimated that DT send was not

recorded at their end. The line was charged by ISP at 23:18 Hrs of 09.07.2017 with delay of 3 Hrs 23 Min.

Despite repeated pursuance from SLDC, line could not be charged timely and ISP did not intimate SLDC

regarding details of fault at their end. Outage of this critical element of the transmission network for such a long

time may affect the grid security. The ISP is requested to submit detailed report regarding false DT received

and delayed synchronisation of the ckt for discussion in the meeting.

Representative from ISP informed the committee that the above tripping occurred due to PT fuse fail

and ensured that in future the reason for tripping & readiness for charging of element will be provided on time.

SA-II Frequent tripping of 132 KV Datia - Railway Traction Ckt – II on overload :- Member

Secretary OCC informed committee that it is to intimate that 132 KV Railway Traction – II emanating from 132 KV S/s Datia of MPPTCL s/s is tripping frequently on overload in past few days. Details of tripping of feeder are given below:-

The Current Transformer (CT) and other equipments installed at 132 KV sub-station Datia on 132 KV

Railway Traction feeder I & II, are of the ratings as per earlier Contract Demand of Indian Railway with Discom.

Now the Indian Railways has increased drawal from 132 KV sub-station Datia by putting some additional load

on this TSS. Continuous excess drawal of power by Railways i.e. beyond the permissible capacity of the

equipments installed at Datia on railway bay may cause failure of equipments at MPPTCL end.

In view of the above it is requested that additional load connected to 132 KV Datia TSS in the recent

past may be taken off immediately and Railway should maintain their drawal at this TSS point below 24 MVA

for safeguard of the equipments installed at MPPTCL end.

Member Secretary OCC stated that the railway shall reduce the loading of the circuit if it is possible,

otherwise if its not possible to reduce the load, the matter shall be takeup with T&C for capacity augmentation

of equipments required to avoid over loading at this feeder. Accordingly T&C shall prepare a proposal as per

the loading requirement and intimated to Railway..

Representative from Railway informed the committee that railway is ready to augment the equipment

as per the proposal submitted by MPPTCL.

SA-III MP Overdrwal on dtd. 08.07.2017 : Member Secretary OCC informed committee that on 08th and 09th July there was heavy MP overdrawal from the grid. WRLDC was also issuing warning notice to SLDC for

restriction of drawal within schedule. The shift incharge SLDC requested the shift incharge MPPMCL control

room thorugh telephonically as well through email. However no action has been taken by MPPMCL.

Overdrawal by MP from the grid on 08.07.2017 on account of the following factors –

• Intermediate dry spell in the region leading to rise in temperature and consequent demand

• Reduction in generation from wind RES

• Restriction on generation from hydro stations of Indirasagar, Omkareshwar & Sardar Sarovar

• Absence of adequate thermal capacity on bar.

Looking to the constant schedule of ISP & OSP and other factors mentioned above, the power from other

sources would have been arranged by MPPMCL on day-ahead basis which have not been done. WRLDC has

opened 4 lines of MP due to continuously overdrawal of MP from grid which had deteriorated grid security. The

MPPMCL is required to always maintain the drawal within safe and secure limits and cooperate in system

operation in order to avoid jeopardise the grid.

The Matter was discussed in the meeting. Member Secretary informed the committee that the overdrwal of MP

on dtd 08.07.2017, WRLDC has taken seriously in the OCC meeting of WR, He further informed that the

overdrawal was also observed on last few days but on dtd 08.07.2017 there was huge overdrwal by MP and

WRLDC has opened 4 lines of MP and further tripping of other line may lead to grid disturbance. He also

informed that due to looking of demand which are continuously increasing day by day, MPPMCL should plan

to take RSD units on bar for meeting the increased demand.

SA-IV Maintaining reserves to handle grid contingencies :- Member Secretary OCC informed committee that as per the CERC suo-motu orders, secondary reserves of 800 MW has to be maintained at the

regional level while the States have to maintain tertiary reserve of 330 MW in Maharashtra, 330 MW in Gujarat;

300 MW in Madhya Pradesh; 250 MW in Chhattisgarh. WRLDC has taken this point for discussion in

forthcoming OCC of WRPC. It is mentioned in WRPC OCC Agenda that the OCC members may like to

deliberate on the following issues: 1. Ensuring real-time telemetry from RES in the State 2. Forecast of RES

and demand by the SLDCs 3. Keeping thermal units on bar to maintain spinning reserve in the grid. MPPMCL

and RE generators are requested for necessary action in this regard.

The Matter was discussed in the meeting. Member Secretary requested MPPMCL to take necessary

action to keep the reserve as mandated by CERC in its order.

ITEM No 10 : DATE AND VENUE OF NEXT OCC MEETING :

It is proposed to hold 59th Operation and Coordination Committee meeting of MP on 29.08.2017. The host and venue of the same shall be intimated seperately.
