43 Annexure-5.0 SYSTEM DISTURBANCE December 2013 & January 2014 System Disturbance / System Incidence : 1. System Disturbance on at 220KV S/s Shivpuri: On dated at around 03:05 Hrs MP System was normal and frequency of N-E-W Grid was HZ. Prior to fault 132 KV Motijheel Banmore Ckt I & II, 132 KV Motijheel Mahalgaon Ckt and 132 KV Motijheel Tigra Ckt were open hence 132 KV S/s Motijheel and 132 KV S/s Jora was radially fed from 220 KV S/s Sabalgarh. At 03:10 Hrs. 220 KV Shivpuri Bina (PGCIL) Ckt tripped from both ends due to transient fault and 220 KV Shuvpuri Bina Ckt tripped from 220 KV S/s Bina end only, resulting 132 KV Shivpuri Pachhore Ckt tripped due to over loading and 132 KV Interconnector II also tripped from 220 KV S/s Shivpuri end. Consequently interruption occurred at 220 KV S/s Shivpuri, 220 KV s/s Sabalgarh, 132 KV S/s Shivpuri, 132 KV S/s Kolaras, 132 KV S/s Mohna, 132 KV S/s Vijaypur, 132 KV S/s Sheopur, 132 KV S/s Jora, 132 KV S/s Motijheel. There was consumer load loss of approx MWH due to above tripping. There was no generation loss and System was normalized in due course of time. 2. System Disturbance on at 400 KV Indore: On dated at around 06:00 Hrs MP System was normal and frequency of National Grid was HZ. At 400 KV S/s Indore, all 400 KV feeders were in charged condition and normally loaded. At 06:05:41 Hrs fault occurred on Y- Phase of 400 KV Indore Itarsi Ckt I and after 40 msec (i.e., at 06:05:41:530 Hrs) Y Phase breaker of 400 KV Indore Itarsi Ckt I opened. After 960 msec (i.e., at 06:05:42:491 Hrs) Y Phase Breaker of 400 KV Indore Itarsi Ckt I auto- reclosed. But as the fault was not cleared Main 2 protection relay again operated at 06:05:42:877 Hrs and after 40 msec (i.e., at 06:05:42:917 Hrs) Breaker of all the three phases opened with Y Phase, Zone I, Km relay indication. Due to the above tripping Bus Bar Protection for Main Bus II operated. After taking the Bus Bar protection out from service, 400 KV Bus II at 400 KV S/s Indore was charged by charging 400/220 KV ICT IV at 07:32 Hrs. Subsequently system were normalized in due course of time. Minutes of 38th OCC of MP 41

44 Annexure 6.9 LOGIC TO BE IMPLEMENTED IN TRANSCO SCADA FOR ADMS Requirement in SCADA Terminal at DISCOM Control Centre: The DCC terminal of Transco SCADA shall have a overviews for ADMS and other features which shall include (for particular DISCOM) : (i) The list of groups which qualify to be operated under ADMS on the day of the week with real time total load of the group. (ii) The LIST of ADMS Groups on the week day with current status of the Group i.e. OPERATED or NORMAL. There should be provision for Enabling/Disabling the group for ADMS. It shall also be possible to Trip/Close particular selected Group from this window by issuing command. The user operations shall be permitted through password. (iii) When selected the group, a separate window shall open listing the 33 KV feeders in the group with status ( Operated / Normal ). From here the provision shall be available to Enable/Disable each feeder for ADMS operation. It shall also be possible to Trip/Close particular selected feeder from this Window by issuing command. The user operations shall be permitted through password. (iv) There shall be an Alarm Window which will list the activities by the user and also the list of Group/feeders operated under ADMS (if a Group/feeder normalized then the alarm should disappear). It shall also have listing of failed operations (i.e. if a group/feeder failed to Trip/Close through ADMS). Each activity Alarm (User actions, Group/Feeder Operation, Failed Operations) shall be displayed in different colour. (v) It shall be possible to open at least 4 windows simultaneously and by size zoom it shall be possible to view four active windows at a time. (vi) The addition/deletion of feeder/group shall not be permissible through DCC terminal. This activity shall be permitted to the System Administrator of Transco SCADA.

45 LOGICS FOR ADMS (1) The Group covered on the day under UFR shall be excluded from ADMS. (2) If Freq <50.00 Hz and MP OD is > 12% of schedule or 150 MW whichever is less continuously for 15 minute duration, then calculate the quantum to be shed through ADMS. (3) Calculate the Overdrawing DISCOM s Load to shed on the basis of its prorata quantum in MP O/D. (example : suppose OD is MP is 300 MW and 12% of schedule is 100 MW then load to be shed will be 300 MW, D1 O/D by 200 MW, D2 by 150 MW and D3 U/D by 50 MW, then D1 shall shed =200*300/350= 171 MW. load and D2 shall shed by (150*300/350)= 129 MW, by operating 1 or more groups in the overdrawing DISCOM as per requirement (equal to the prorata overdrawal quantum). This would either lead to Zero or slightly underdrawal position. (4) If the total quantum of Groups to be shed in a overdrawing DISCOM exceeds its total prorata quantum, then in last groups less feeders shall operate to match to ZERO O/D. (5) The groups in particular DISCOM shall operate under ADMS in rotation. This means that if there are total 30 groups, then group 1 will again operate next time after group 30. (6) The under drawing entities shall not operate. (7) The group if continuously under ADMS outage should be automatically normalized after 1 hour of operation and simultaneously next group shall operate to compensate for OD. (8) On clearing of the OD condition and U/D reached upto 100 MW for continuously 15 minute or more than 150 MW instantly, then normalisation shall start with First- Operated first normalized basis. (9) Iterations (1) to (8) shall be continuous process. This would ensure that the ADMS operates only when the MP overdrawal crosses 12% 0r 150 MW (whichever is less) barrier continuously for 15 minute duration. (10) If the Group/feeder does not operate, then Alarm message shall appear in the DCC Terminal of TRANSO SCADA, giving the details of the Feeders not operated in that particular group or the non-operation of complete group. In such case DCC may issue instruction to s/s through Control Centre (sub LDC or Transco SCADA centre) to trip particular 33 KV feeders or can manually issue trip command from SCADA.
