Stage-III of df/dt which was set at 49.2 Hz, 0.4 Hz/sec has to be upgraded to 49.9 Hz in line with above revision. The above df/dt settings has been further classified constituent-wise in Western Region in the present ratio as given below : Settings Load Relief (MW) Recommended Hz/ (Hz Sec) Region GETCO MPPTCL MSETCL CSEB TPC 49.9/(0.1 Hz/sec) /(0.2 Hz/sec) /(0.4 Hz/sec) GRID DISTRUBANCE As per CEA regulations 2010, the Grid Standards and Grid Incidents are classified as under : (a) Grid disturbance means tripping of one or more power system elements of the grid like a generator, transmission line, transformer, shunt reactor, series capacitor and Static VAR Compensator, resulting in total failure of supply at a substation or loss of integrity of the grid, at the level of transmission system at 220 kv and above. (b) Grid incident means tripping of one or more power system elements of the grid like a generator, transmission line, transformer, shunt reactor, series capacitor and Static VAR Compensator, which requires re-scheduling of generation or load, without total loss of supply at a sub-station or loss of integrity of the grid at 220 kv and above. In the event of a grid disturbance, highest priority is to be accorded to early restoration / revival of the system. During restoration, it is possible that system may have to be operated with reduced security standards and under suspension of all commercial incentives / penalties. This chapter forms the guidelines for classifications of disturbances into different categories for the purpose of analysis and reporting. Annual Report , SLDC, MPPTCL, JBP 21

26 Classification of Grid incidents and disturbances: As per CEA regulations on Grid standards 2010, the categorisation of grid incidents and grid disturbances shall be as follows:- (a) Categorisation of grid incidents in increasing order of severity - Category GI-1 - Tripping of one or more power system elements of the Grid like a generator, transmission line, transformer, shunt reactor, series capacitor and Static VAR Compensator, which requires re-scheduling of generation or load, without total loss of supply at a sub-station or loss of integrity of the grid at 220 kv. Category GI-2 - Tripping of one or more power system elements of the grid like a generator, transmission line, transformer, shunt reactor, series capacitor and Static VAR Compensator, which requires re-scheduling of generation or load, without total loss of supply at a sub-station or loss of integrity of the grid at 400 kv. (b) Categorisation of grid disturbance in increasing order of severity,- Category GD-1 - When less than ten per cent. of the antecedent generation or load in a regional grid is lost; Category GD-2 - When ten per cent. to less than twenty percent of the antecedent generation or load in a regional grid is lost. Category GD-3 - When twenty per cent. to less than thirty per cent. of the antecedent generation or load in a regional grid is lost; Category GD-4 - When thirty per cent. to less than forty per cent. of the antecedent generation or load in a regional grid is lost; Category GD-5 - When forty per cent. or more of the antecedent generation or load in a regional grid is lost.

31 3 OCC Meeting During the Year the SLDC has conducted the Operation coordination committee meeting as detailed below : th OCCM on th OCCM on th OCCM on th OCCM on Black-Start mock drill of Hydel Power Stations Electrical power system comprising transmission, sub-transmission and distribution networks facilitating the transfer of power from widely spaced generating stations to the consumer load centers is one of the critical infrastructures for any country. A blackout in a power system can be conceived as the total failure of power supply in an area due to failure of associated generation or transmission facilities. The restoration of the area blacked out in the least possible time assumes highest precedence for a power system operator post the event since the impact of a black out multiplies with the duration of the event. The strategy for restoration depends on the degree of system failure. A blackout might be a partial one covering a certain pocket of the large power system or in the worst case it could be a complete system blackout. Accordingly the strategy adopted may be a top-down approach where in start-up power is extended from neighboring healthy system up to the nearest generating unit in the affected area, else it may be a bottom-up approach where in the generating units capable of self-start are black-started [generally with local diesel generator(dg) sets] and subsystems are gradually built around the self-started units with some radial load, expanded gradually by synchronization of those small sub-systems among themselves and finally with the main grid. All efforts are made to restore the system post black out in the minimum possible time. Black start exercises in an islanded real time sub-system comprising loads and generating stations capable of self start, is a learning exercise to gain preparedness all form of blackouts. Such exercises are beneficial for reducing the time taken during actual system restoration following a disturbance and also to address systemic deficiencies detected during the process. Another aspect of robustness of a system can be illustrated by the fact that a weaker system that has a well-tested plan for emergency procedures and for restoration may be more reliable than a stronger system with no such plan. The Central Electricity Regulatory Commission (CERC), India also mandates such exercises biannually The black start exercises have been carried out at Indira Sagar Hydro Power Station located in Khadwa District, on 22 nd May 2011 and at Rani Awanti Bai Sagar Hydel Power Station, Bargi on 10 th February Black Start Exercise at Indirasagar HPS The exercise has been jointly carried out by engineers from MP State Load Despatch Centre Jabalpur, Western Regional Load Despatch Centre Mumbai, Indira Sagar Hydro Power Station, MP Power Transmission Co. Limited, Indore and Paschim Kshetra Vidyut Vitaran Company Limited Indore. Annual Report , SLDC, MPPTCL, JBP 27

32 Indira Sagar hydro power station (ISP) is located at Narmada Nagar, 10 km away from the village Punasa in Khandwa district of Madhya Pradesh. It is a multipurpose project on the river Narmada with installed generation capacity of 1000 MW (8 x 125 MW). In order to create a total black out scenario at ISP, a detailed procedure based on the bottom up strategy for black start exercise was prepared. A small area around ISP was identified to be islanded from rest of the grid. The planned island comprised of one 125 MW unit at ISP, radially feeding identified block loads at 220/132/33 kv Jetpura S/S through 400/220 kv Indore S/S. The above sub-system thus created was planned to be synchronized with rest of the grid at Indore S/S. Since Indore S/S was having facility for check-synchronization with its 400 kv bus-couplers, the same was identified as the point of synchronization of the island with rest of the grid. Availability of one 50 MVAR line reactor (L/R) on 400 kv ISP-Indore line at Indore end was an added advantage for reactive power management during the exercise. Further the shorter line length of 400 kv ISP-Indore (80kms each circuit) lines compared to 400 kv ISP Nagda (188 kms each circuit) lines also went in favor of selection of Indore for the exercise instead of Nagda. The schematic diagram of the island is indicated below. The transmission and distribution operators involved in the black start exercise were kept in synchronism with the modus operandi of the entire exercise, well in advance to avoid any inadvertent switching operation during the exercise. The procedure of switching arrangements at different substations involved in the exercise along with targeted time line for each step was released well in advance. The black start exercise was suitably planned on 22nd July, 2011 (Sunday) in consultation with all concerned. That day being a holiday, alternative supply to the loads fed from 132 kv Jetpura bus could be ensured without any major constraint. The black start plan was executed in 4 major steps viz. (1) Preparatory activities such as bus splitting and shifting of identified elements on to the desired bus, (2) Formation of the is-land by separation of the sub-system with one unit at ISP feeding identified radial load at Jetpura via Indore S/S, (3) Self-Starting one unit with a stand-alone DG set at ISP and gradually building up the Is-land after complete blackout of Fig. the is-landed sub-system., (4) Synchronization of the subsystem with rest of the grid at Indore 400/220 kv S/S. The exercise was Annual Report , SLDC, MPPTCL, JBP 28

33 successfully completed and Black start capability of the Generator got tested. The performance as recorded in the SCADA system is given below : This black start exercise was unique in regards to using a large generator (125 MW), 400 KV line with reactor, 400/220 KV ICT, 200 KV line, 220/132 KV transformer, 132 KV line, 132/33 KV transformer and 33 KV lines. Apart from Generating stations three substations of different voltage ratings have participated in the exercise. The exercise also tested various capabilities of the generator and transmission system. The capabilities of the generator that got tested include the capability to self-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 in partial loading condition without losing stability etc. The transmission capabilities that were put to test include the ability of switch gear to charge dead bus, healthiness of bus coupler breakers, capability of reactive resources (line reactor etc.), flexibility available in protection systems in terms of operating at other than normal settings for a temporary period, healthiness of synchronizing facilities available at important substations etc. 4.2 Black Start Exercise at Bargi HPS : The black-start exercise for Bargi HPS unit was carried out on 10 th February, This black start exercise involved two major stages viz 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, and then 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 multipurpose hydro power station nearest to Jabalpur city having capacity of 2x45 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 maximum loading of about 28 MW was recorded in morning hours Annual Report , SLDC, MPPTCL, JBP 29

34 on 40 MVA transformer in February The complete black start mock exercise was conducted successfully at Bargi HPS between 10:25 Hrs to Hrs on 10 th February The performance as recorded in the SCADA system is given below : 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 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 Annual Report , SLDC, MPPTCL, JBP 30

35 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. 5 System Operators Training Organised by PSTI, Bangalore As per recommendation of Pradhan Committee on Man Power Certification, Incentive and ring fencing Load Despatch Centre, the Load Despatch personals are required to undergo basic level System Operator Training.

Total load interrupted was 865 MW. Annual Report , SLDC, MPPTCL, JBP 82

87 Restoration was started by charging ICT-I at 400Kv S/s Nagda by Hrs. and the system fully normalized by Hrs. 9. Tripping around Nagda, Jetpura & Badnagar area on The 400 KV Indore- Nagda lines tripped from both ends on at about 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 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 ( = 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 : (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 I (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 hrs and 400 KV ISP-Nagda Ckt hrs. 10. Tripping of 400 KV feeders at Indira Sagar Pow er Station on On at about hrs, due to prevailing high voltages at Nagda and Indira Sagar, SLDC had given instructions to open 400 KV ISP-Nagda line. However as per SCADA archieved data, at 22:27:30 hrs 400 KV ISP-Indore Line-II and at 22:28:22 hrs 400 KV ISP-Indore Line-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 hrs after charging of 400 KV ISP-Indore Ckt. II and subsequently other 400 KV Ckts. From ISP have been restored. 11. System occurrence at 400 KV S/s, Bhopal on at Hrs 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 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 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 hrs by charging 220 KV side of 315 MVA ICT-I with 220 KV Bus-I. At hrs 220 KV Bus-tie charged. The restoration of the feeders and transformers done sequentially and by hrs the complete system was normalized. There was no interruption to any area due to this tripping. Annual Report , SLDC, MPPTCL, JBP 83

88 12. System occurrence at 400KV S/s Indore on At about Hours 220KV South Zone ckt-ii tripped on B-ph, Zone-1 indication, simultaneously 220KV Bus-II Busbar protection operated hance all connected feeder to 220KV Bus-II tripped at 4ooKV S/s Indore. Same was charged by availing supply through Barwaha Ckt-II at hrs. and there after system normalized. Due to this occurrence 10 to 20 Min interruption occurred in 220KV s/s Indore SZ and 132KV s/s Chamble, Satya-Sai, Mangliya, Indore- West & Ghatabillod. 13 Tripping of 220 KV lines on at around hrs: - On dated at hrs, MP system was running normal at frequency 49.9 Hz. At around hrs, it has been reported that 220 KV Birsinghpur-Jabalpur line II was tripped and auto-reclosed at Jabalpur end and tripped from Birsinghpur end on ABC phase, Zone I & II indications. Further to the tripping mentioned as above, 220 KV IC No. 1, 2 & 4 between Birsinghpur Power House and 220 KV sub-stations also tripped from Power House end. The line fault of 220 KV Birsinghpur-Jabalpur II was cleared from Birsinghpur 220 KV sub-station end, hence the tripping of 220 KV IC No. 1, 2 & 4 appears to be due to over reach of protection. It is therefore necessary that DPR settings provided on 220 KV Birsinghpur- Birsinghpur inter connectors may be checked and corrected at SGTPS Birsinghpur end so that the unwanted trippings of lines could be avoided. Results of the DPR testing may also be intimated by the SGTPS, Birsinghpur to this office at an earliest. 14 System disturbance on at hrs at 220 KV Satna, S/s :- On dated at hrs, M.P. system was running normal at frequency Hz. At around hrs, it has been reported that at 220 KV Satna sub-station R-phase over head conductor between gantry to gantry of 220 KV Satna-Chhatarpur line snapped and fall on 220 KV Main bus-i. There was a bus fault occurred due to snapping of conductor as detailed above. All 220 KV & 132 KV line emanating from 220 KV Satna sub-station tripped, hence total supply failed. 105 MW Tons machine No. 1 & 2 also tripped. There is provision of Bus-bar protection scheme which is under commissioning, hence total supply was failed on both the bus. Annual Report , SLDC, MPPTCL, JBP 84
