MINUTES OF 39TH MEETING OF OPERATION & COORDINATION COMMITTEE OF MP HELD ON 28TH APRIL 2014 AT 11.00 AM AT CONFERENCE HALL OF MD, BHOPAL
39th meeting of Operation & Co-ordination Committee of MP was held on 28th April 2014 at Conference Hall of MD, Bhopal. The list of participants is enclosed at Ann.-1.0.
Shri Rajeev Agrawal, GM(DCC), MPPMKVVCL, Bhopal welcomed all the participants attending
39th Operation and Coordination Committee Meeting. He wished for qualitative and fruitful discussion during the meeting and requested Shri PAR Bende, Chairman, OCC to commence the 39th OCC meeting. Shri P.A.R. Bende, Chairman, OCC welcomed all the participants attending 39th Operation and Coordination Committee Meeting. He informed the committee that this is the 25th OCC meeting organised by SLDC. He further stated that the issues discussed during these last 25 OCC meetings helped all the state grid entities for better operation of the grid and also various operational issues were resolved in the meetings. He stated that CERC is now very active and recently issued the notice to all SLDCs under section 142 of EA 2003 for non implementation of Automatic Demand Management Scheme in the state. SLDC has filed the review petition before the Hon’ble CERC by mentioning that the work of implementation of ADMS in the state is already in progress and SLDC is continuously taking up the matter with DISCOMS by arranging several meetings.
He further informed that as per recommendation made by grid enquiry committee, third party
protection audit of sub-stations and power stations has to be carried out. SLDC had constituted a group of engineers from MPPTCL, MPPGCL, NHDC and SLDC for performing Internal Protection Audit of various important sub-stations and Power Stations. These groups had completed the protection audit of 37 sub-stations and Power Stations. He requested all the entities to rectify the problems/ discrepancies observed during the Internal Protection Audit within the timeline specified by the CERC. SLDC has to compile report of action taken on discrepancies observed during the Internal Protection Audit and submit to the WRPC for onward submission to the CEA. It is observed from the report submitted to the SLDC that some of the deficiencies are not resolved by the entities. SLDC is continuously pursuing all the entities to carry out third party protection audit. The CERC vide order dated 21.02.2014 has made SLDC responsible to monitor the action taken by State entities and if the deficiency in the state system in regard to category A is not corrected after 3 months of issue of CERC order, the SLDC is to approach the State Commission for appropriate action against defaulting state entity. He further informed the status of third party protection audit of each entity as below:
1. M/s BLA- completed 2. M/s JP Bina Work order issued 3. MPPTCL Work order of 8 nos. 400 KV Substation has been issued 4. NHDC Under progress 5. MPPGCL Under Progress
Chairman, OCC requested MPPTCL to arrange third party protection audit of remaining sub-stations of MPPTCL and also requested NHDC and MPPGCL to take immediate action in this regard. As per CERC order the frequency response has to be computed by RLDC/SLDC if the load/Generation loss is more than 1000 MW. He further informed that in November 2013 there was a grid disturbance of GD-1 category occurred in Western MP with load loss around 1200 MW. The FRC was
39th Minutes of OCC of MP 1
computed by SLDC and it is observed that no primary response has been given by any of the eligible generator in the state. It indicates that RGMO/FGMO is not properly implemented in the generators. He further stated that since last year there is almost zero load shedding, hence the anticipated demand for next year can be computed most effectively as the actual unrestricted demand of the Discom/state is available now. The deviation settlement mechanism has been implemented w.e.f 17.02.2014 and SLDC in co-ordination with MPPMCL has been able to maintain the deviation generally within specified volume limits by regulating Hydel generation/surrendering power in ISGS/SSGS but it is observed that Discoms do not take any action for keeping their deviation within limits. The violations of deviation limits by MP is very less as compared to other constituents of WR. He further stated that Central DISCOM has intimated that the entitlement given by SLDC is not as per their load forecasting. In this regard Chairman OCC informed that the anticipated load forecasting of DISCOMs cannot be treated as their entitlement. The entitlement of DISCOMs is computed based on the share allocated by GoMP and weighted average allocation of power to MPPMCL. Now MPPMCL has started reallocating the share from the power stations allocated to MPPMCL, to three DISCOMs as per their load forecasting on day ahead basis and SLDC may start issuing the entitlement to DISCOMs by considering day ahead allocation of MPPMCL power to DISCOMs, shortly as modification in ABT software is under progress.
Thereafter, Chairman, OCC requested Shri K.K.Parbhakar, Member Secretary (OCC) to take up the agenda items for discussion. ITEM NO. 1 : CONFIRMATION OF MINUTES : Member Secretary stated that minutes of 38th meeting of Operation & coordination committee of MP held on 25 February 2014 at State Load Despatch Centre were forwarded to the committee members vide No. 07-05/SG-9B-II/1234 dated 01.04.2014.

ITEM NO. 3 : OPERATIONAL PLANNNING 3.1 Generating Units under planned outage and proposed maintenance programme : Member Secretary informed the committee that there is no planned outages of MPPGCL thermal units during April 2014 and May 2014. The Annual Maintenance programme of Thermal and Hydel unit of MPPGCL and NHDC is enclosed at Annexure 3.1.
Chairman OCC stated that the capacity of 1040 MW, 1320 MW and 840 MW of Thermal units
shall remain under planned outage during the months of July, August & September 2014 respectively which is also not in line with the tentative maintenance programme of MPPGCL Thermal units submitted for preparation of LGBR of Western Region for the year 2014-15. The outage of such a large capacity of thermal units during the month of July & August is not desirable for safe & secure operation of the state grid. Further, barring one unit at Gandhisagar HPS, none of the hydel machines at other HPS have been taken for AOH as per schedule given by MPPGCL, which will result in unavailability of hydel units during monsoon season if scheduled AOH of hydel machine is delayed. He requested MPPGCL to submit the revised schedule of AOH of Thermal & Hydel machines to SLDC at the earliest.
Member Secretary informed that Indira Sagar has started AOH of their machines as per plan
submitted by NHDC whereas Omkareshwar has not taken any of their machines for AOH. He requested OSP representative to complete the AOH programme in such a way so that all the machines shall be available during rainy season.

39th Minutes of OCC of MP 9
The Southern Regional Load Despatch Centre, Bangalore has filed a petition no. 302/MP/2013 before the Hon’ble CERC in the matter of endangering the secured gird operation through inadequate / non-performance of RGMO / FGMO with manual intervention and non-compliance of regulation 5.2(f), (g), (h), (i) of CERC (IEGC) regulation 2010 read along with regulation 5(2) of CERC (IEGC) (first amendment) regulation 2012 by the generators in Southern Region. Petition was listed for hearing on 18.03.2014 and decision / Record of proceeding of CERC is awaited. Further as discussed in the 38th OCC meeting all the eligible generators were requested to revise the setting of RGMO as per CERC (IEGC Second amendment) regulation 2014 implemented wef 17.02.2014. Only JP Bina has confirmed compliance of the same.
Chairman OCC stated that since last three years the matter has been taken up with MPPGCL by SLDC to install the RGMO in their Thermal and Hydel units where RGMO has not been provided so far. MPPGCL has submitted information on 09/5/2014 indicating the details of units where installation of RGMO is in progress and units for which exemption will be sought from CERC. 6.4 Response of FGMO/RGMO installed at generating stations during the incident at 400 KV S/s Nagda on 18.11.2013 : Member Secretary informed the committee that the CERC in the petition No. 47/MP/2012 has issued directives that all generating stations shall comply with the regulations 5.2 (f) of the Grid Code and failing which appropriate proceedings shall be initiated against them for non-compliance with the provisions of the Grid Code and directions of the Commission. The CERC has approved the procedure for Assessment of Frequency Response Characteristic (FRC) of control system of Indian power system. The FRC will be computed for all events involving a sudden 1000 MW or more load/generation loss or a steep change in frequency by 0.50 Hz. The same (FRC) shall be worked out by NLDC, RLDCs and SLDCs to compute each interconnection/region/control area’s FRC. Accordingly, MP SLDC has computed the FRC of the incidence occurred at 400 kV Nagda sub-station at 07.32 Hrs on 18.11.2013 in which supply was interrupted at 40 nos. EHV sub-stations in Western MP. There was load loss of around 1195 MW and generation loss of 92.68 MW. The frequency increased from 49.993 Hz to 50.233 Hz i.e. 0.24 Hz increase in frequency was observed. The data for FRC calculations is taken from the real time telemetered data recorded by the SCADA systems installed at MP SLDC. In the study of FRC, it is observed that FGMO/RGMO schemes installed at various eligible generating stations have not given any primary response, the copy of the report of FRC is enclosed as Annexure 6.4. The details of the load of generators on which RGMO is installed on bar, before and after the above incident are as follows:- S.No. Utility Generator Generation
This indicates that the RGMO/FGMO had not given adequate response rather most of the units have shown reverse response which is violation of IEGC. It is therefore requested that the matter should be taken up seriously and ensure that the RGMO/FGMO shall always remain in service. The FRC has been submitted to WRLDC for onward submission to CERC. NHDC has informed the committee that the matter has been taken up with M/s BHEL for carrying out the study for non-operation of RGMO in their units. Member Secretary requested MPPGCL to revise the frequency setting as per IEGC amendment and also to investigate the reason for the generators not given response under RGMO. He further informed that JP Bina has confirmed that they have revised the setting as per IEGC. 6.5 IMPLEMENTATION OF AUTOMATIC DEMAND MANAGEMENT SYSTEM : Member Secretary informed the committee that Hon’ble CERC in the Suo Motu Petition No. 208/SM/2011 in the matter of implementation of Automatic Demand Management Schemes have issued an order on 18.12.2013 and point No. 37 of this order is reproduced as under;
Quote 37. We had directed in our order dated 1.12.2011 to all SLDCs to file the current status of the Automatic Load Management Scheme, reasons for not implementing the scheme and status of contingency procedures.

System Disturbance / System Incidence :
1. System Disturbance on 12.03.14 at 220KV S/s Pandhurna: On dated 12.03.2014 at around 15:15 Hrs MP System was normal and frequency of National Grid was 50.01 Hz. At 15:17 Hrs, 220 KV Sarni – Pandhurna Ckt. tripped at 220 KV S/s Pandhurna end, simultaneously LBB protection operated due to wiring problem in breaker from manufacturing side resulting remaining 220 KV Pandhurna – Kalmeshwar Ckt. and 220 KV Pandhurna – Chhindwara Ckt. tripped. Consequently total supply failed at following S/s’s 220 KV S/s Pandhurna, 132 KV S/s Multai and 132 KV Rly. Traction – I & II at 220 KV S/s Pandhurna were also interrupted.There was a consumer load loss of about 34 MWH due to above tripping. There was no generation loss and System was normalized in due course of time.
2. System Disturbance on 13.03.14 at 220KV S/s South Zone, Indore: On dated 13.03.2014 at around
09:15 Hrs. MP System was normal and frequency of National Grid was 49.96 Hz. At around 09:20 Hrs. ‘R’- Phase PT of 132 KV Bus – I at 220 KV S/s SZ Indore burst due to which 220/132 KV, 160 MVA X’mer – III & IV, 132/33 KV, 3X40 MVA X’mer – I, 132 KV Incomming – II (i.e., 132 KV side breaker of 220/132 KV, 3X40 MVA X’mer – II) at 220 KV S/s SZ Indore, 220 KV SZ Indore – Indore Ckt. – II, 132 KV SZ Indore – Satya Sai Ckt, 132 KV SZ Indore – Chambal Ckt tripped and remaining 132 KV feeders were hand tripped as bus fault occurred at 220 KV S/s SZ Indore.

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.
Following data shall be transferred from SLCD SCADA to Transco SCADA system on ICCP for ADMS purpose.
(i) MP Schedule, MP Drawal and MP Deviation (+ OD, - UD) and Local Frequency. (ii) EZ, WZ, CZ DISCOM Schedule , Drawal and Deviation (+ OD, - UD)

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 “FirstOperated” “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.
39th Minutes of OCC of MP 56
(11) In case of underdrawal more than 150 MW below 50.05 Hz or any Under drawal above 50.05 Hz, the DISCOMs should immediately check if any ADMS group is under operated condition and restore the same. Also ensure addition of more loads by normalizing irrigation feeders and rescheduling of power.
