NO. 87 TO 90 FOR LOWERING DOWN THE LINE FOR MAINTAINING CLEARANCE BETWEEN THE E/W OF 220 KV LINE WITH BOTTOM CONDUCTOR OF NEWLY CONSTRUCTED 765 KV BHOPAL-INDORE S/C LINE OF M/S BHOPAL DHULE TRANSMISSION CO. LTD. (M/S AS BDTCL) UNDER CONSUMER CONTRIBUTION WORK: MPPTCL has conveyed approval for crossing of 765 KV Bhopal-Indore S/C line with various transmission lines of MPPTCL vide letter No /B-3132/P&D-TLD/389 dated based on the proposal and profile submitted by M/s Bhopal Dhule Transmission Co Ltd. However, after completion of erection work, BDTCL has observed that the electrical clearance of 765 KV line with 220 KV SukhiSevania- Agenda of 67th OCCM of MP 9

12 Ashta line between location No. 87 to 90 was not adequate. It had probably happened due to negligence workmanship as line was not erected exactly as per provisions of profile. Thereafter the BDTCL has submitted their request to MPPTCL vide letter dated wherein request was made for modification / shifting of 220 KV SukhiSevania-Ashta line (crossing loc. No. 88 & 89) in order to maintain adequate electrical clearance along with consent for bearing the cost of work. Based on the request of M/s BDTCL, looking to target date ofcharging of 765 KV Bhopal Indore Single ckt line an agreement between MPPTCL and BDTL was executed and MPPTCL has accorded permission for lowering down the E/W of 220 KV line as a special case as an interim arrangement till 220 KV line is modified or shifted. After lapse of about 2 years, M/s BDTCL has not undertaken the required modification/ shifting work, evenafter persisting pursuance at different level.the E/W of 220 KV line is still in lowered position due to which the conductors are unprotected against lightening. Moreover, in case of snapping of conductor of 765 KV on 220 KV line would initiate serious fault. In above scenario, it is felt that BDTCL may be advised to complete modification/ shifting work of 220 KV SukhiSevania- Astha line immediately under consumer contribution as per mutual agreement looking to protection issue of 220 KV SukhiSevania-Ashta line. The Committee may kindly discuss the matter and CE(EHT-M&I) & CE(P&D) may update the details in the above matter. [Action:MPPTCL,MPPGCL] 6.8 LOAD DROPPING SCHEME AT 400KV & 220 KV SUBSTATIONS TO HANDLE EMERGENCY CONDITION: - On dtd at 09:55 Hrs. 160MVA 220/120 KV X mer no-2 at 220 CT No.-II at 220 KV S/s Malanpur tripped on on PRV indication due to cable fault. Consequently following X mers and circuits also tripped:- S.NO ELEMENT NAME INDICATION TRIPPING TIME MVA X MER 1 at 132 KV side tripped due to 09:55 Hrs. 220 KV S/s Malanpur. over loading MVA X mer-1 at O/C 09:55 Hrs. 220 KV S/s Mehgaon MVA X mer-2 at O/C 09:55 Hrs. 220 KV S/s Mehgaon MVA X mer at 220 O/C, E/F 09:55 Hrs.

13 KV S/s Ron KV S/s Porsa KV S/s Pratpura KV S/s Barnmore KV S/s Ambah KV S/s Morar KV S/s Gohad KV S/s Morena KV S/s Badgaon Dimni KV Hitampur Railway Traction. In view of above it becomes necessary that in every 400KV & 220KV substation, load dropping scheme invariably made functional so that in case of any emergency situation under N-1 condition, the loading on ICT should not crossed dangerous level. It is gathered that the existing load drop scheme at 220 KV S/s Malanpur is provided on 220 KV Malanpur Gwalior(PG) Ckt- I & II and does not cover the 160 MVA, 220/132 KV X mer I & II at 220 KV S/s Malanpur. Therefore to avoid overload tripping of transmission elements at Malanpur, Mehgaon & Morena it is proposed to review the load drop scheme installed at at these sub stations. However, if load dropping scheme have not been made, so far, it is requested to formulate suitable load dropping scheme to handle sudden emergency as elaborated above in Gwalior area & as well as other important nodes of MP Grid. The Committee may discuss the matter. [Action: MPPTCL] 6.9 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.
