It is indicated that 400/ 220 KV ICT No I AND II have already been commissioned at UMSP Rewa, however we are not in a position to utilize the same. The MPPTCL is requested to give updates on the matter and action taken to mitigates the line/ict constrain. [Action:MPPTCL-(P&D)/(T&C)/(EHT)] Agenda Of 66th OCCM Of MP 8

11 6.3 PROTECTION AUDIT OF HYDEL POWER STATIONS OF MPPGCL:- The MPPGCL vide letter No /601-PSDF, dtd 21/02/2018 has conveyed that protection audit of switchyard associated with 10 hydro power plants of MPPGCL is required to be carried out by WRPC. Further, it was decided that work or protection audit of all switchyard carried by a team constituted by WRPC accordingly nominations were invited from utilities for protection audit team. Vide this office dtd the name of officers from MPPTCL, NHDC and MPPGCL was conveyed to WRPC. MPPGCL is insisting for early completion of aforesaid protection audit, considering provisions of MOM of TESG meeting of PSDF regarding the observations for PSDF grant on MPPGCL proposal in 37th meeting held on As a sequel to above, SE (Protection), WRPC is intimated that looking to difficulties at WRPC level to constitute a committee for aforesaid work, it has been directed that committee may be constituted MP- SLDC. However, detailed programme for Protection Audit to be carried out be intimated to WRPC, so that WRPC may depute one member from WRPC their end. MPPGCL is therefore requested to furnish detailed programme for conducting Protection Audit along with data required in this regard as requested by WRPC earlier, so that proposed Protection Audit could be carried out. Vide this office letter no 07-05/RPC-37A/3218 DTD 12/11/20118,CE O&M-Hydel, MPPGCL has been requested to provide Protection details and associated equipment details in prescribed format of protection Audit so that further action on the matter may be initiated. [Action:MPPGCL] 6.4 DETAILS OF PROTECTION AUDIT AND IMPLEMENTED DEFENSE MECHANISM:- WRPC vide their dtd: informed that The Chief Engineer(NPC)CEA New Delhi vide letter no.7/gsc/npc/cea/2018/ dtd: (enclosed as Annexure-6.4) intimated that in a meeting with Hon ble MoSP(IC) on for discussion of the draft National Electricity Plan, CEA has been requested to prepare report & presentations covering aspects of grid reliability and security, especially with respect to grid failure, etc. Therefore Chief Engineer (NPC) has requested to furnish following details in prescribed format:- i.

[Action:MPPTCL,MPPGCL,NHDC(ISP/OSP),JP Bina,BLA] 6.5 LOW VOLTAGE PROBLEM AT KATNI, REWA, MAIHAR AND SATNA AREA: The outage has been availed on 400 KV Birsinghpur-KatniCkt No.-II on dtd for 3 days for replacement of circuit breaker at Birsinghpur Power House. In the above, context it is mentioned that 400 KV Katni- Damoh line and 220 KV Katni-DamohCkt were under break down since long due to tower collapse. Considering Agenda Of 66th OCCM Of MP 9

12 continuous pursuance of Power House officials outage on 400 KV Birsinghpur Katni Ckt. No-II was permitted. On dtd during evening peak and on dtd , looking to low voltage observed at Katni substation SGTPS Power House officials were contacted and requested to operate their units in over excited mode to inject reactive power in the system within the capability curve so that system may be operated near nominal voltage. However, it has been observed that in spite of repeated request the units were not injected any significant MVAR support. At 11:20 hrs on dtd the code was issued to SGTPS unit indicating required MVR to be injected in the system, however the MVAR support was not increased, on the contrary few units were absorbing the MVAR from the system. In the above context it is mentioned that looking to ensuing Ravi Season load is in increasing trend and MVR demand of the system is increased significantly, it is therefore requested that the reactive power may be injected into the grid by all the generating units within the capability curve as per provisions of grid code. In view of above it is requested that the concerned official may please be directed suitably in this regard and be adhered to directives to control the low voltage, by injecting maximum MVAR within capability curve. The MPPGCL may kindly brief the issue to the Committee. [Action:MPPTCL,MPPGCL] 6.6 DELAY IN SYNCHRONIZING UNIT OF BARGI POWER HOUSE AFTER ISSUE OF CODE FROM SLDC ON DTD DURING EVENING PEAK:- It is being observed that unit No.-I at Bargi HPS, takes considerable time in synchronizing, after issue of code from SLDC. In the above context, it is conveyed that on dtd the code was issued by SLDC at 17:03 hrs for taking the units of Bargi Hydel Power Station, on bar looking to increasing trend of demand and considering system exigencies. The unit No.-II was synchronized at 17:15 hours, however, the unit I could be synchronized only at 18:20 hrs after elapse of one hour seventeen minutes. Delay in synchronizing the unit with the system is not understandable. Moreover, no any reason was conveyed to SLDC for such abnormal delay. It may be appreciated that during evening peak hours load are in increasing trend and system frequency goes to minimum level. Looking to system contingency, such delay is not desirable and not warranted for smooth operation of integrated system. The MPPGCL is requested to indicate the reason of aforesaid problem and remedial action thereof. [Action: MPPGCL] 6.7 INSPECTION OF RELAYS OF AUTOMATIC UNDER FREQUENCY LOAD SHEDDING AND CERTIFICATION THEREOF: - It is desired that for safe & secure operation of integrated system, the under frequency relay should be connected in the system in healthy condition. Accordingly, WRPC is pressing hard to provide the self-certified status of healthiness of relays of Automatic Under Frequency Load Shedding (AUFLS) and periodic checking of the same. Vide this office various correspondence. The CE (T&C) and also SE(T&Cs) were requested to provide status of healthiness of relays of Automatic Under Frequency Load Shedding on priority basis to SLDC, so that same may be communicated Agenda Of 66th OCCM Of MP 10

13 to WRPC. Inspite of repeated request vide various correspondence, moreover the matter had been raised in OCC meeting of MP in time to time, however the desired information are still awaited from utilities. It is therefore desired that the above matter may be treated as urgent and status of healthiness of Automatic Under Frequency Relays may be provided to SLDC and also the under frequency may be tested periodically. In this context it is also mentioned that time to time WRPC official as well as SLDC official shall visit the sub-stations to ascertain the healthiness of under frequency relay. Committee may please discuss the matter. [Action: MPPTCL(T&C/P&D), Discoms] 6.8 UNDER FREQUENCY RELAY OPERATION AT 15:47 HRS ON DTD AT CHHINDWARA:- On , at 15:47 hrs under frequency relay was operated at 220 KV substation Chhindwara and 132 KV substation Chhindwara, resulted interruption to 11 nos feeders. The system frequency at that moment was running at the level of Hz. It appears that under frequency relay was maloperated at Chhindwara sub-station. The SE (Testing), Chhindwara has been requested vide this office letter that under frequency relay at Chhindwara be got tested and the cause of tripping may please be conveyed to this office. It is therefore requested MPPTCL may please apprise the reason of under frequency relay operation and action taken thereof. [Action: MPPTCL] 6.9 PROVISION OF SYNCHRONIZATION FACILITY AT EHV SUB-STATIONS OF MPPTCL AND AT ALL POWER HOUSE: - As per Grid Code, the synchronization facility should be available at all the Power Stations, 400 KV Sub-stations, 220 KV Sub-stations and 132 KV sub-stations in the path of black start. In 60 TH OCC meeting MPPTCL representative informed the committee that order for 69 no. synchronization trolleys has been placed and 1 no. synchronization trolley has been delivered for checking and testing purpose at 220KV S/S Barwaha. In subsequent meetings this issue has been discussed. However, no any fruitful progress has been observed so far. In the above context it is indicated that at Manikheda HPS and Rajghat HPS synchronization facility is not available. It is felt that every Hydel Power station should be equipped with synchronization facilities invariably for system reliability and Crises Management. Also at Manikheda HPS & Rajghat HPS single bus system exists, hence MPPGCL is requested to explore the possibility for commissioning of Double Main Transfer Bus system. Thus, MPPGCL is requested to provide synchronization facility at Manikheda HPS and Rajghat HPS is therefore requested, the MPPGCL may kindly provide status of making synchronization facility in aforesaid HPS. The MPPTCL may kindly provide the status of installation and commissioning of synchronization trolleys at different substations. Further, is also requested to indicate, whether synchronization facility could be provided at Karera & Pichhore substation on priority basis. The matter was discussed in the meeting.
