Member Secretary pointed out that as per MPEGC no EHV element including protection can be taken out from service without consent of SLDC. Similarly the forced outage of any EHV element is required to be brought out into the notice of SLDC within 24 hours of event. However, MPPGCL has not intimated the same so far which is a serious lapse. The outage of 400 KV protection scheme at SGTPS Birsinghpur is reported as under commissioning stage, whereas SGTPS Birsinghpur had earlier informed that the same is taken out in December 2012 due to mal-
27th OCC Minutes 7 operation. This need to be clarified by MPPGCL. Chairman OCC expressed his concern on such large number outages of EHV elements in thermal power stations which remained non reported till SLDC sought status report. He further clarified that SLDC is required to file monthly report to MPERC in which long outages of transmission and generation elements is included. He requested MPPGCL to furnish the action plan to put back these important elements into service.

27th OCC Minutes 8 2012. However the Grid Disturbance and Grid Incidents in MP categorized under GI-01 and GD-02 are indicated in Annexure 5.0. The Committee noted the same.
ITEM NO. 6.0 : OTHER IMPORTATNT OPERATIONAL ISSUES
6.1 Black-Start mock drill of Hydel Power Stations:
6.1(i) Action on the outcome of Black Start at ISP: Member Secretary requested concerned utilities to intimate the follow up actions taken on the observations of WRLDC on black start mock drill of ISP.
1. ISP, NHDC informed that M/s BHEL is analyzing the issue. Since M/s BHEL is not responding therefore ISP is developing its own scheme so as to ensure operation of units under speed control mode during black start/islanding operation. The scheme developed shall be got approved by M/s BHEL.
2. Member Secretary requested T&C to inform the action taken in the matter of reported problem in synchroscope at 400 KV Indore. T&C assured to confirm the same. Shri Vasant Mehto, Advisor, MPPTCL advised that voltage setting of the feeder qualified for black start should be increased before performing the black start mock drill and this should be worked out before finalizing the mock drill.
6.1(ii) Auto Start facility on DG sets at Hydel Power Stations of MPPGCL: MPPGCL informed the committee that DG set at Pench HPS shall be available from March 2012.
6.1(iii) Black Start mock drill at Bargi HPS: Member Secretary informed the committee that a mock drill black-start exercise for Bargi Hydro unit was successfully carried out on 10th February 2012 and SLDC is pleased to place on record the cooperation, assistance and efforts made by all the concerned officials of MPPGCL, MPPTCL, Bargi Hydel Power Station, 132 KV Lakhnadaun S/S ,GCC MPPGCL and DCC EZ during the mock black start exercise.
He further stated that the results of black start exercise of Bargi HPS have been quite satisfactory. The restoration of the supply to Lakhnadaun area post black out took about 23 minutes which could have been reduced to 16 minutes if the bus PT fuse did not blow out at Bargi. The restoration of the system within this short time without any abnormal behavior of voltage, frequency and other electrical parameters will help in restoration process in real time.
The subsystem in island condition (132 KV Bus-1 Bargi HPS and Lakhnadaun) operated for almost 7 minutes pre-black out (10:45 Hrs to 10:52 Hrs) and 25 minutes after black start (11:15 hrs to 11:40 Hrs). The frequency of the island remained close to 50.0 Hz, which shows that the unit is perfectly working in free governor mode. The DG set at Bargi HPS do not have auto start facility and thus started manually.
The capabilities of the generator that got tested during black start exercise include the capability to start from a DG set, to regulate the active and reactive power output so as to operate the island at reduced standards of frequency and voltage, to operate under partial loading condition without losing stability, primary response of the generator, healthiness of synchronisation facility etc. The transmission capability that were put to test include the ability of switch gear to charge dead bus, healthiness of bus breakers, flexibility available in protection systems in terms of operating at other than normal settings for a short period.
Member Secretary requested MPPGCL to give priority to sort out following issues so that during actual black start problems do not come up :

Annexure 5.0 GRID DISTURBANCE AND GRID INCIDENT REPORT
(1) Occurrence at 400 KV Nagda S/S on 21.12.2011 : On dtd. 21.12.2011 at about 05.05 hrs. all 400KV breakers of 400KV Main bus-I at 400 KV s/s Nagda got tripped through 400KV bus bar protection without any indication / event / disturbance in the relay. 315MVA X’mer No. I & II were connected with Main bus-I hence total load shifted on 315MVA X’mer No.-III, thus overload scheme operated at 400KV S/S Nagda, causing total interruption to the large area around Ujjain / Ratlam / Neemuch / Badnagar. Total load interrupted was 865 MW. Restoration was started by charging ICT-I at 400Kv S/s Nagda by 06.35 Hrs. and the system fully normalized by 07.00 Hrs. This grid incidence was of GD-2 category.
(2) Tripping of 400 KV feeders at Indira Sagar Power Station on 25.01.2012- On 25.01.2012 at about 22.27 hrs, due to prevailing high voltages at Nagda and Indira Sagar, SLDC had given instructions to open 400 KV ISP-Nagda line. However at 22:27:30 hrs 400 KV ISP-Indore II and at 22:28:22 hrs 400 KV ISP Indore Ckt. I got tripped. At the same time 400 KV ISP-Nagda line was opened at ISP causing outage of all the lines as the remaining line i.e. 400 KV ISP-Sarni tripped 52 milliseconds after opening of 400 KV ISP-Nagda line on high voltage. As the generating units were not running at the time of tripping there was no generation loss, however the system reliability reduced on account of these trippings. The restoration process started immediately but got delayed as the breakers at ISP could not be hold. The supply to ISP has been restored at 23.28 hrs after charging of 400 KV ISP-Indore Ckt. II and subsequently other 400 KV Ckts. from ISP have been restored.
(3) Tripping around Nagda, Jetpura & Badnagar area on 04.01.2012- The 400 KV Indore- Nagda lines tripped from both ends on 04.01.2014 at about 14.17 hrs (400 KV ISP-Ngada was already open). The total load on this line mainly shifted on 220 KV Indore-Badnagar link (already carrying about 140 MW) and associated 132 KV links emanating from 220 KV S/s, Jaitpura & Ujjain. The 220 KV Indore-Badnagar feeder got tripped on over current at 14.17 hrs due to increased loading. 160 MVA, 220 /132 KV X-mers I & II also got tripped at the same time at 220 KV Sub-station Jaitpura on overloading. The load of 220 KV s/s Badnagar (140 MW), 220 KV Ratlam links (50 MW), 220 KV S/s, Jaitpura (223 KW approx.) got shifted to 400 KV Nagda ICTs (510+140+50+223 = 923 MW approx.).
Due to overloading of ICTs at 400 KV Nagda, the load dropping scheme Stage-I operated and following feeders and X-mers got tripped achieving a load relief of 106 MW :
27th OCC Minutes 44 (i) 132 KV Sailana feeder (from 220 KV S/s, Ratlam)
(ii) 132 KV Mahitpur I & II (from 220 KV S/s, Nagda)
(iii) 132 KV Alot (from 220 KV S/s, Nagda)
(iv) 33 KV incoming I & II of 100 MVA X-mer (from 220 S/s, Nagda)
(v) 132 KV Tarana I & II (from 220 KV S/s, Ujjain)
The total load interrupted was of the order of 106 MW approximately. The restoration process started by closing Indore-Badnagar Ckt. at 14.34 hrs and 400 KV ISP-Nagda Ckt. 14.53 hrs.
(4) System occurrence on 31.01.2012 at 18.08 Hrs at 400 KV S/s, Bhopal – A shut down was availed by MPPTCL on 220 KV Bus-II and 315 MVA , 400/220 KV ICT No.1 at 400 KV S/s, Bhopal on 31.1.2012. After completion of work, 220 KV bus-II was charged by closing bus coupler. While normalizing the bus arrangement when 315 MV A 400/220 KV ICT -II was shifted on 220 KV Bus-II at 18.18 hrs, all 220 KV feeders & transformers tripped due to operation of 220 KV Bus-bar protection, thereby causing tripping of all the 220 KV feeders and ICTs from 220 KV side at 400 KV S/s, Bhopal. The normalization started at 18.26 hrs by charging 220 KV side of 315 MVA ICT-I with 220 KV Bus-I. At 18.31 hrs 220 KV Bus-tie charged. The restoration of the feeders and transformers done sequentially and by 18.52 hrs the complete system was normalized. There was no interruption to any area due to this tripping.
27th OCC Minutes 45 Annexure- 6.1(iii) Black-Start mock drill at Bargi Hydel Power station
A mock black-start exercise for Bargi HPS unit was carried out on 10th February, 2012. SLDC Jabalpur is pleased to place on record the cooperation, assistance and efforts made by engineers from Bargi Hydel Power Station, MP Power Transmission Company, 132 kV Lakhnadaun substation, Generating Control Centre and East DISCOM Control Centre during the mock drill of black start. This black start exercise involved two major stages:
a) Stage-I : Creating an islanded subsystem by separating out unit #2 (45 MW) at Bargi HPS along with radial load at 132/33 kV Lakhnadaun s/s fed through 132 KV bus #1 of bargi HPS, followed by operation of the created island around the Bargi unit for some time.
b) Stage-II : Creating a blackout in the islanded subsystem created with one unit (45 MW unit #2) of Bargi and radial load at 132/33 kV Lakhnadaun s/s, start of one unit at Bargi, charging of one dead 132 KV bus at Bargi, charging 132 kV Bargi- Lakhnadaun line, islanded operation of the Bargi HPS unit with radial load at Lakhnadaun s/s followed by synchronising this island at Bargi HPS.
Bargi is the nearest Hydel power station to Jabalpur. Capacity of the plant is 2x45 MW = 90 MW. Bargi HPS is interconnected with Jabalpur 220 KV sub-station through 132 KV D/C line and to Lakhnadaun 132 KV S/s through 132 KV S/C line. One 132/33 KV 40 MVA transformer at Lakhnadaun S/s feeds consumer load through 5 Nos. 33 KV feeders. The Black Start Mock Drill was proposed to be conducted after creating island at 132 KV Lakhnadaun S/s with Unit No.2 of Bargi HPS. Lakhnadaun 132 KV S/s is having two 132 KV buses - one Main and one Auxiliary bus, 1x40 MVA 132/33 KV transformer and two 132 kV lines viz, 132 KV Lakhnadaun-Seoni S/C & 132 KV Lakhnadaun-Bargi S/C. The maximum loading of about 28 MW was recorded in morning hours on 40 MVA transformer in February 2012
The loading of each feeder at 33 KV system at 132 KV Lakhnadaun S/s was recorded at 10:30 Hrs on 10th February 2012 as detailed below-
SNo. Name of the feeder Load 1. Jhabua Power Ltd 0 2. Bhimgarh 160 Amp/8MW 3. Lakhnadaun 130 Amp/6 MW 4. Ghansaur 144 Amp/7 MW 5. Dhooma 83 Amp/4 MW Total load on 40 MVA transformer ~ 25 MW
Prior to start of black start mock exercise it was ensured that 132 KV Lakhnadaun S/s is fed from 132 KV Bargi HPS as well as 132 KV Seoni S/s and all 33 KV feeders shall also be in
27th OCC Minutes 46 charged position. It was also ensured that both 132 KV Bargi-Jabalpur feeders, Unit # 1 & 20 MVA station X-mer are kept on 132 KV Main bus-II, 132 KV bus-coupler in closed position at this stage and Unit # 2 and 132 KV Bargi-Lakhnadaun feeder on 132 KV Main bus-I. This scheme has ensured availability of Unit No.1 at Bargi HPS with 132 KV Jabalpur S/s through Bus-II during mock drill.

Fig. 1. ARRANGEMENT OF BLACK START MOCK DRILL AT BARGI HPS
The complete black start mock exercise has been conducted at Bargi HPS between 10:25 Hrs to 11.42 Hrs on 10th February 2012. The procedure followed is detailed below :
(1) Islanding of 132 KV Lakhnadaun S/s WITH Unit No. 2 (45 mw) at Bargi HPS
1. The droop setting of Generator under Black Start Mock Drill was 5%.
27th OCC Minutes 47 2. Generation on 45 MW unit #2 at Bargi HPS adjusted equal to load on 132/33 kV 40 MVA transformer (~27 MW) at 10:35 Hrs.
3. Breaker of 132 KV Lakhnadaun-Seoni line opened at Lakhnadaun s/s at 10:38 Hrs. After ensuring Generator output is equal to load connected at 132 KV Lakhnadaun s/s, 132 kV bus-coupler breaker opened at Bargi HPS at 10:45 Hrs on issue of instruction by SLDC forming an island around are fed from 132 kV Lakhnadaun s/s. This exercise was done as bus coupler ammeter at Bargi was found not showing correct reading.
4. The generator output adjusted to match the load. However, the frequency variation from 44.5 Hz to 52.2 Hz has been observed in the islanded system fed from Bargi Unit #2 (45 MW) before getting stabilized. The primary response of the governor was observed and found working. The islanded system with about 25 MW load was run for about 7 minutes.
(2) Blackout in the area fed through 132 KV Lakhnadaun :
1. After stabilizing the island for few minutes, Unit No.# 2 was hand tripped at 10: 52 hrs after hand tripping of 0.4 kV incomer (auxiliary supply). This has created black out in the area fed from Lakhnadaun S/s.
2. The breakers of 33 KV breakers of 132 KV Lakhnadaun S/s alongwith breaker of 132 KV Lakhnadaun-Bargi, 40 MVA Transformer (both ends) hand tripped. Similarly 132 KV Bargi-Lakhnadaun breaker has been hand tripped at Bargi HPS.
(3) Black Start Operation : The black-start activities of machine No. 2 at Bargi HPS have been carried out as given below :
1. As soon as Unit No.2 is tripped and black out occurred, the D.G. set should start automatically. As the auto start up facility is not available with DG set at Bargi HPS, the same has been started manually at 10:55 Hrs.
2. 0.4 kV supply extended to unit bus to start essential auxiliaries and essential auxiliaries of Unit No. 2 taken into service. 3. SLDC issued instruction at 10:58 Hrs to start Unit No 2. Unit rolling started at 11:00 Hrs. and 132 KV Bus #1 charged at 110 kV at 11:05 Hrs. 4. 132 KV Bargi-Lakhnadaun line charged at 11:07 hrs from Bargi end and Lakhnadaun end at 11:08 Hrs.
5. Breaker of 40 MVA 132/33 kV transformer at Lakhnadaun closed at 11:08 Hrs and voltage of 132 Kv bus at Lakhnadaun adjusted to 126 kV by raising generator voltage at Bargi. The frequency of Unit #2 has been set At 50.5 Hz. At this stage R-Phase bus PT fuse has got blown out which got replaced at about 11:15 Hrs.
6. As per instruction of SLDC, 33 KV Lakhnadaun line charged at 132 KV Lakhnadaun s/s at 11:15 Hrs with load of about 4 MW. Then at 11:16 Hrs 33 kV Ghansore line taken on load. The frequency in the islanded area was 50.2 Hz. Then other 33 kV
27th OCC Minutes 48 lines at Laknadaun s/s also closed. The load in the islanded area after black start was as below : The primary response of governor has maintained the frequency in the islanded area close to 50.0 Hz. The islanded portion operated for about 25 minutes without any difficulty.
7. The islanded portion check-synchronized with the NEW grid by closing 132 kV Bus coupler at Bargi HPS at 11:40 Hrs.

Fig 3. Plot of Bus 132 kV -1 Voltage at Bargi HPS which was part of the island during black start exercise
Observations and analysis of the exercise : The results of black start exercise of Bargi HPS has been quite satisfactory. The restoration of the supply to Lakhnadaun area post black out took about 23 minutes which could have been reduced to 16 minutes if the bus PT fuse did not blow out at Bargi. The restoration of the system within this short time without any abnormal behavior of voltage, frequency and other electrical parameters will help in restoration process in real time.
The graphical plots in Fig. 2 & 3 based on the achieved data at SLDC indicate various observations made during the exercise. The subsystem in island condition operated for almost 7 minutes pre-black out (10:45 Hrs to 10:52 Hrs) 25 minutes after black start (11:15 hrs to 11:40 Hrs). The frequency of the island remained close to 50.0 Hz, which shows that the unit is perfectly working in free governor mode.
The DG set at Bargi HPS do not have auto start facility and thus started manually. MPPGCL may explore the possibility of installing auto start facility so that the DG set start automatically in real time under black out conditions.
The capabilities of the generator that got tested during black start exercise include the capability to start from a DG set, to regulate the active and reactive power output so as to operate the island at reduced standards of frequency and voltage, to operate under partial loading condition without losing stability, primary response of the generator, healthiness of synchronisation facility etc. The transmission capability that were put to test include the ability of switch gear to charge dead bus, healthiness of bus breakers, flexibility available in protection systems in terms of operating at other than normal settings for a short period.
27th OCC Minutes 50 Other observations that need immediate attention by MPPGCL are described hereunder :
(1) After opening of bus coupler at 10:38 Hrs at Bargi HPS, 48 Volt charger tripped and as 48 VDC battery is in bad condition the telemetry become out till battery charger put back into service at about 11:06. Thus vital data for this period is not available. The 48 VDC battery therefore need to be replaced within the shortest possible time. The cause of tripping of 48 V charger also need to be investigated by MPPGCL.
(2) The hunting of Generator output (Unit 2) also observed in GT control panel and as telemetry transducer inputs are extended from the same control panel, the hunting also recorded in SLDC SCADA system. The hunting to the extent +22 to -24 MW observed though the generation and frequency was stable. This also need to be investigated and corrective measures should be taken by MPPGCL.
(3) The ampere meter on 132 kV Bus coupler panel at Bargi HPS was showing 130 Ampere current irrespective of load and even when both buses were isolated by opening bus coupler, the meter continued showing 130 Amp current. The ampere meter need to be recalibrated/replaced.
Conclusion : Black out in power grid is a worst kind of contingency and brings unpleasant situations when it occurs. Since the power systems worldwide are evolving both in size and complexity, the conventionally adopted recovery procedures requires constant review, upgradation, test and validation. The black start exercises assume vital importance for any large interconnected power system since they do not only testify the existing restoration facilities but also prepare the system operators to restore the power system in a shortest possible time by identifying deficiencies and suggesting scopes for improvement.
