The restoration of 400 KV ISP-Indore-II and 400 KV STPS-ISP lines was done at hrs and hrs respectively. ISP did not intimate the reason for delay in charging of these important 400 KV lines. It is indicate that 400 KV ISP-Indore-II and 400 KV STPS-ISP lines form important corridor for transfer of power from Central to West MP and outage of this critical corridor for such a long period without any justified reason is not desirable for safe, secure and reliable operation of the State Grid. The ISP is requested to avoid unwarranted delay in charging transmission elements in future. [Action: NHDC] 6.5 Non-compliance of SLDC instructions by Gandhisagar HPS On , Wind Power generation in MP was suddenly increased to 1000 MW from 140 MW during the evening peak hours. SLDC had to accommodate such a huge additional power in the system by maintaining the grid parameter within operational limits. As emergency measures hydro generation is to be c urtailed immediately which is the only possible solution for keeping the grid security intact till the effect of backing down / surrender of power in thermal generating stations is obtained. Gandhisagar Hydel Power Station was instructed to stop three machines for which code were issued at 20:25 Hrs through GCC. The shift officials of Gandhisagar HPS were reluctant to stop the machines even during emergency conditions despite SLDC request to act immediately. After repeated persuasion machines were not stopped by Operation staff Gandhisagar. Finally the matter was brought in the notice of CE (O&M:Hydel) and after his intervention, the machines were stopped at 21:01 Hrs, 21:05 Hrs & 21:10 Hrs. This act of the shift officials of Gandhisagar is violation of Clause 3.83 of MPEGC, Clause 5.1 (d) of IEGC and Sec. 29 of EA-2003 i.e. non-compliance of SLDC instructions. It is requested that the shift officials of Hydel Power Stations may be instructed to follow the instructions of SLDC promptly in future. [Action: MPPGCL] 6.6 Scheduling of DVC and Inter-state IPP Power :- Scheduling of DVC and Interstate IPP is being done by the WRLDC. Under day ahead scheduling these entities furnished entitlement of MP to SLDC and these entitlements are forwarded to MPPMCL Control Room for preparing requisitions. The requisition received from MPPMCL again forwarded to DVC / IPPs for obtaining their consent to the power requisitioned by the MPPMCL. On receiving the correspondence from DVC / IPPs the same is again forwarded to MPPMCL. Finally, MPPMCL again gives comments (agreed/ Not Agreed) on the revised quantum of power in 15 minutes time block agreed by the generator. Now SLDC punched the final requisition submitted by MPPMCL in WRLDC web based Scheduling Portal and forwarded to the concern. Similar procedure is also being adopted during the real time scheduling. Agenda for 56th OCCM of MP 9

12 This procedure of scheduling is not mandated in IEGC / MPEGC / BSC 2015 and also consumes the valuable time of system operators of SLDC which is otherwise required for smooth system operation. Also during real time scheduling such procedural delay is causing on scheduling of power from designated time block. MPPMCL in future submit requisition to SLDC only after obtaining the consent of DVC / Interstate IPPs and SLDC shall not make communication with these entities for obtaining consent on t he requisition furnished by the MPPMCL and the same requisition shall be treated as final and punched on the web based scheduling portal of WRLDC. [Action: MPPMCL] 6.7 Questionnaire on Hydro Generating Stations :- As per decision taken in 18 th meeting of Forum of Load Despatcher (FOLD) held on 21 st November 2016, working Group on Hydro for studying the various aspects of hydro Stations may be formed.

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- 6.8A. 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 6.8B 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 [Action: MPPGCL/MPPTCL] 6.9 MAPPING OF FEEDERS WIRED UNDER AUFLS TO SLDC SCADA :-. In the 4th, 5th & 6th NPC meetings, mapping of the Feeders / Lines covered under AUFLS on SCADA systems of SLDC's/RLDC's was discussed. NPC have desired that monitoring of the feeders / loads under the AUFLS shall be done at SLDC's / RLDC's, so as to ascertain that the desired results are ensured during the events, frequency falling below the AUFLS frequency settings. In the 6th NPC meeting it was therefore desired that all the loads/feeders wired under the AUFLS is monitored in Western Region also and the progress be s ubmitted to NPC. A list of feeders/loads implemented under AUFLS in WR was compiled at WRPC in 2014 and same is uploaded in website of WRPC under news section and PCM Minutes section. MPPTCL is requested to initiate the process of mapping these feeders in the SCADA System so that same Agenda for 56th OCCM of MP 10

13 shall be made available to WRLDC. MPPTCL is requested to update the list of feeders under AUFLS and intimate the feeders which have already been mapped in their SCADA System and are monitored on line by them. Also constraints, if any, faced in mapping AUFLS feeders in their SCADA System may be intimated.
