The 63rd meeting of Operation & Coordination Committee of MP was held on 26th April 2018 at 11:00 AM at Conference Hall, SLDC, MPPTCL, Nayagaon, Jabalpur. The list of participants is enclosed at Annexure -1.0.
Shri K.K.Parbhakar Chairman OCC & Chief Engineer SLDC welcomed all the guests and participants for 63rd OCCM. Chairman OCC stated that the Stated OCCM of MP is conducted bi-monthly, it is a platform where operational issues related to grid and all the entities are discussed and resolved amicably for safe & secure grid operation. Presently there are no major issues faced in grid operation due to development and strengthening of transmission network. He also stated that no feedback is received or no issues are raised in MP OCC by the entities connected to the Grid. Thereafter he requested all the entities that if they are facing any problems related to grid operation, it should have raised in the meeting for discussion.
Further he informed the committee that on 20th April 2018, MERC has issued the Forecasting,
Scheduling, DSM & Related matters of Wind & Solar Generating Stations Regulations 2018, where in the complete procedure and calculations for deviation & settlement for RE Generators (Wind & Solar) are defined/explained. Creation of separate pool account is also defined for RE Generators (Wind & Solar). Further he also informed the committee that Forecasting, Scheduling & DSM for RE generation connected on 33 KV is to be done by respective Discoms for which procedure is being prepared by SLDC as per the directives of MPERC Regulation. As per the existing practice of MPERC for DEZ by Discom, similarly for DSM of RE generators the capacity building, software development & creation of virtual pool account in the existing pool account has to be done by Discoms. He also stated that the Regulation is applicable w.e.f 20.04.18, hence Discoms will require forecasting data to issue DSM account and can get the initial forcasting data from SLDC if it is not available with the Discoms.
Chairman OCC also informed the committee that one of the major issues to be addressed at present is
the DC revision/ reducing the DC by thermal generators in last minute/real time due to coal shortage. He stated that intimation of DC revision due to coal shortage/tube leakage, delay in intimation to SLDC/MPPMCL creates difficulties in maintaining the load and generation balance resulting O/D. Looking to the present scenario where Hydel Generation is being scheduled as per Administrative and irrigational requirement of NVDA/WRD to fulfill the irrigation/water supply requirements in various regions and also no load shedding is allowed or being done, hence it is difficult to operate the grid in safe, secure and balanced manner with these restrictions. He informed the committee about the tube leakage incident at STPS#11, which was known to the officials at STPS one day prior taking the M/C Off-Bar but was intimated on last minute to SLDC/MPPMCL. The Chairman OCC requested MPPGCL & other thermal Power Stations to intimate SLDC/MPPMCL well in advance about DC revision/reduction in DC due to Coal Shortage, tube leakage, reasons well known in advance so that power can be arranged and planning can be done in advance to mitigate the demand & restrict O/D for safe and secure Grid Operation. Thereafter Chairman OCC apprised the committee & congratulated MPPGCL for Lit-Up of SSTPS Phase-II Unit-3. After brief deliberation of Chairman, he requested Member Secretary OCC to take up the agenda points.

6.2 Load Dropping Scheme at 400 KV substations to handle emergency condition: - It was
apprised to the committee that on dtd. 17.04.2018 at 12:15 hrs 315 MVA 400/220 KV ICT No.-II at 400 KV
substation (PG) Gwalior tripped and caught fire. The fire was rapidly spread nearby area. Therefore 315
MVA 400/220 KV ICT No-I was also hand tripped at 13:32 hrs. to safeguard the ICT. Thereafter the loading
of 315 MVA ICT No.III rushed dangerous level of 390 MW. The contingency arrangements were made to
handle the emergency situation immediately as detailed below: - 1. The load of 220 KV Mehgaon substation shifted to Auriya supply of NR BY by opening of 220 KV
Malanpur-Mehgaon and 132 KV Malanpur-Mehgaon lines. The load of Mehgaon, Bhind, Ron, Lahar,
Seondha, Gormi, Porsa, Ambha met from Auraiya supply.
2. 220 KV supply extended to Datia substation from 400 KV substation Bina . This supply also extended up
to 220 KV substation Mahalgaon . 220 KV Gwalior (PG) Mahalgaon circuit were kept off.
3. The load of Sheyopur & Sabalgarh substations were fed from 400 KV substation Bina (PG). The 132
KV link from Motizeel substation to Sabalgarh substation kept off.
4. The load of Guna, Ashoknagar and 220 KV substation Bina were fed from 220 KV Sagar supply. This
supply was also kept parallel with Vidisha supply.
5. The 220 KV Malanpur and Morena substation were made available supply from 315 MVA 400/220 KV
ICTNO.I at Gwalior (PG).
At around 22.00Hrs ICT No I at PG Gwalior restored and supply arrangement made as per
original scheme except at Mehgaon S/S .
Further on dtd. 18.04.2018, the emergency situation again arise at Gwalior area as 315 MVA
ICT No.II which was under breakdown and the PG Gwalior has requested for availing emergency
shutdown on ICT No.I as Tan Delta of B-Ph. 220 KV bushing was found high and the same bushing of
the ICT required to be replaced immediately. To manage the emergency condition again contingency
arrangements were made to handle the load of Gwalior Region. As the shut down was requested for
three days on continuous basis therefore extra arrangement felt needed in order to ensure uninterrupted
supply to Gwalior area, therefore following arrangements were made.
i. 220 KV Bina had been fed from Bhopal supply through 220 KV Vidisha and Ganjbosoda feeder.
The 220 KV Bina interconnector No. I & II kept off.
ii. 220 KV Sagar supply was extended to Datia substation through split bus arrangement at 400
KV substation Bina. The Ashoknagar and Guna substation were also kept on Sagar supply.
iii. The supply of 400 KV substation Bina extended to Mehalgaon substation. Thus Mehalgaon
substation was made available, Bina supply as well as Sagar supply (through Datia substation).
6. The load of 220 KV Mehgaon substation was already on Auriya supply and 220 KV Malanpur-Mehgaon
and 132 KV Malanpur-Mehgaon lines were off. The load of Mehgaon, Bhind, Ron, Lahar, Seondha,
Gormi, Pursa, Amba met from Auraiya supply.
i. The load of Sheopur , Sabalgarh substations were fed from 400 KV substation Bina (PG) . The
132 KV link from Motizeel substation to Sabalgarh substations were kept off.
ii. The 220 KV Malanpur and Morena substation were made available supply from 315 MVA
400/220 KV ICTNO.I at Gwalior (PG). Nevertheless, the MP Demand was minimum at time of
incidence, therefore situation could be possible to control. Obviously, in case of high Demand
Minutes of 63rd OCCM of MP 8
period, such situation may adversely affect the system and it may not have possible to maintain
uninterrupted supply during such situation.
In view of above it was elaborated that it becomes necessary that in every 400 KV 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 therefore, MPPTCL is requested to
review the load dropping schemes and furnish details of scheme available with all important substations at
least upto 400 KV level. 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.
Member Secretary OCC stated that in spite of such critical contingency the system was managed
without interrupting any area, by the combined efforts of SLDC/MPPTCL/WRLDC and congratulated all the
concerned entities for the same. He further stated that during such alert condition the system is difficult to
manage and a proper load drop scheme shall be implemented. Hence it is requested to MPPTCL to review
the existing load drop scheme and to implement new load drop scheme as per requirement as per undated
network and submit to SLDC
6.3 Frequent Tripping Of 132 KV VSTPS- Waidhan Ckt –I & II:- The committee was informed that on
11.04.2018 following lines tripped at 21:10 Hrs :- 1. 132 KV VSTPS- Waidhan Ckt-I (through auxiliary bus at Waidhan substation feeding to Morwa
substation). 2. 132 KV VSTPS-Waidhan Ckt-II. 3. 132 KV Morwa –Jayant Ckt- I & II .
The supply was resumed from Annupur substation, this caused 23 minutes interruption to Waidhan, 20
minutes to Rajmilan substation and 26 minutes interruption to Morwa s/s & Jayant feeders. It is mentioned
that when 132 KV Morwa-Jayant Ckt-II charged, after 3 minutes this line again tripped alongwith 132 KV
Morwa-Rajmilan and 132 KV Annupur-Rajmilan Ckt. This caused 22 minutes interruption to Morwa
substation and 27 minutes interruption to Jayant feeders .
It was pointed out that 132 KV VSTPS –Waidhan Ckt-I &II along with other EHV lines radiating from
Waidhan / Morwa substation are being tripped frequently during recent past , resulting interruption to
mines area. The frequent interruption to mines area is not desirable. The details of trippings on EHV
elements at Waidhan Morwa area are annexed. The EHT M& I representative was requested to look into
the matter and asked to arrange thorough.
It was also pointed out that whenever any line from Waidhan substation got tripped, tripping on other
EHV lines radiating from Waidhan / Morwa substation are also taking place. As Waidhan substation is
adjacent to Vindhayachal Super Power Station, therefore multiple tripping on EHV elements at these area
is not desirable, looking to system security and reliability of integrated system. The (T&C) representative
was requested that relay coordination at Morwa / Waidhan and Rajmilan substations may please be
examined and remedial action may kindly be ensured. Further frequent tripping at Morwa/ Waidhan area
Minutes of 63rd OCCM of MP 9
may please be analyzed and report thereon may please be provided so that same may be appraised to
WRLDC Mumbai. The tripping details were also apprised as Annexure-6.3. The (T&C) representative has
informed that there is some relay coordination issue with VSTS. Therefore it was also decided that the
matter shall be put up before state level relay setting review group of wrpc.
6.4 Formation of State Level Relay setting group- Review and Coordination of relay setting in state of MP:- The committee was apprised that s decided in 128th Protection Committee meeting of
WRPC held on 06th & 07th Dec. 2016 , relay review group for state of MP has been constituted vide this
officer letter No.07-05/RPC-14/596 Jabalpur dtd 22.05.2017. All entities have been requested to provide
relay settings of all important nodes & all other nodes where relay settings are required to be examined
considering protection issues. As desired by WRLDC important nodes like Indore PG, Bhopal etc. required
to be examined first, which have huge effect on reliability and security of Grid.
It was infoThe first meeting of State Level Relay Setting Group convened on 18th August 2017 at SLDC
for review the existing relay settings of critical state network and state network incidental to ISTS and to
provide necessary interface between utilities/entities.
All the members were requested to make arrangement to furnish details of relay settings of all important
nodes, so that same may be communicated to all members and existing setting of critical nodes could be
reviewed & corrective measures may be taken. Attention was also invited to members that SLDC have
made multiple correspondences in this regard, however except MPPGCL, no any other utility has provided
the desired data. It is accordingly desired that the data may please be provided immediately to SLDC.
During discussions, it was envisaged that relay setting of ISPs, OSP nodes required to be examined
first, as in recent past, frequent undesirable trappings were observed due to probable mismatch of relay
coordination issue. Accordingly, ISP, OSP representatives were requested to provide relay setting of ISP,
OSP nodes so that same could be validated by the committee in the next meeting. The consolidated relay
setting data has not been received by the entities. The desired data may kindly be submitted in the meeting
by all the entities. It has now been decided that the meeting of the State Level Relay Setting Group of MP
shall be organized on 10th May 2018 to discuss relay coordination issue at Omkareshware and Damoh
node therefore MPPTCL. NHDC, PGCIL may furnish the desired details of relay settings provided at these
nodes so that the matter may be discussed on 15th May 2018 and needed action on the matter may be
initiated.
6.5 Procedure for availing outage on ISTS EHV elements and OCC approval thereof: - The
committee was briefed that as per standard procedure of WRPC, all EHV elements which have been listed
under the list of important grid elements of Western Region, the outages for such elements required OCCM
approval. All such proposed outages of interstate and 400 KV transmission elements of next months should
be got approved in the OCCM of WRPC in the current month. All the constituents of WR shall inform to the
WRPC for readiness for availing outage of transmission elements on D-3 basis. Further, as decided non-
Minutes of 63rd OCCM of MP 10
OCCM outages should be discouraged. Only under exceptional cases, the request for transmission outage
after issue of OCCM minutes must be posted through email for concurrence of WRPC Member at least
three days in advance. The matter has also been discussed in various OCC meetings of MP and it is observed that the
standard procedure for availing outages on interstate and 400 KV elements is not followed by the utilities. It
is observed that routine maintenance shutdown proposal and the shutdown proposal of construction
activities are being sent to SLDC on D-3 basis, whereas such proposal should have been incorporated in
OCCM proposal. Such practice should be strictly avoided. It is worthwhile to mention here that WRPC
/WRLDC are reluctant to entertain non-OCCM outages for maintenance / construction activities. Only
emergency outages are considered on D-3 basis. It is therefore desired that all utilities may please ensure
that all maintenance/ construction activities may be planned well in advance and such proposal should have
invariably incorporated in OCCM proposal. It is also mentioned that due to any reason if any OCC approved
outage could not be availed, in that case such proposed outages could be rescheduled and approval of
WRPC/WRLDC could be obtained. However, no any outages could be considered which has not been
incorporated in OCCM proposal. It was pointed out that the aforesaid instruction be complied by EHT-Const
wing also as WRLDC/WRPC is reluctant to accord approval on D-3 basis for construction activities. The
Committee may discuss the matter.
T&C, EHT-Maintenance and EHT-Construction, MPPTCL was requested to submit the compiled shut
down list to be submitted timely to SLDC for submission in WRPC OCCM.
6.6 Integration of Satna-Satna (PG) Inter-connector After LILO of 220 KV Satna-Chhatarpur Line From Satna (PG) S/s:- The committee was apprised that the 220 KV Satna-Chhatarpur line which was
initially radiating from Satna S/s, now has been LILO at 400 KV Satna (PG). Thereafter, 220 KV Satna (PG)-
Chhatarpur line and 220 KV Satna-Satna(PG) Inter connector are integrated in the system. It is also
mentioned that 220 KV Satna-Katni line as a stop gap arrangement, is being utilized as 220 KV Satna-
Satna(PG) Inter-connector-III. Now after integration of Satna-Satna (PG) Inter connector consequent of
LILO of Satna-Chhatarpur line, 220 KV Satna-Katni line required to be restored as per approved
configuration. It is also mentioned that newly connected Satna-Satna(PG) Inter connector is carrying less
than half load in comparison to other three no. inter connector. After conversion of Satna-Satna Inter
connector No.3 as 220 KV Satna-Katni line, only 2 & half carrying capacity will be available between Satna-
Satna( PG). Looking to prevailed load pattern reduced capacity inter connector will create over loading
problem. On dtd. 28.11.2017 at 12:54 Hrs, loading recorded between inter connector Satna-Satna(PG) are
indicated below-
220 KV Satna-Satna (PG) Ckt.I - 141 MW (approximate line length is about 1 KM)
220 KV Satna-Satna (PG) CktI.II - 139 MW (approximate line length is about 1 KM)
220 KV Satna-Satna (PG) Ckt-III - 129 MW (approximate line length is about 1 KM)
(This Ckt. No.III shall be converted as 220 KV Satna-Katni line.)
220 KV Satna-Satna (PG) Ckt-.IV - 56 MW (approximate line length is about 4 KM)
Minutes of 63rd OCCM of MP 11
Considering loading of EHV elements at Satna-Rewa area, it would not be appropriate to run one inter
connector with half capacity. It is therefore felt that some modifications are required in 220 KV Satna-Satna
inter connectors. It may please be verified whether newly constructed Satna-Satna(PG) ckt. (having half
load capacity as inter connector due to higher line length) could be utilized for connecting Satna(PG) - Katni
line, so that existing arrangement of 220 KV Satna-Satna(PG) Ckt. III could be continued and uniform
loading on all 3 Nos. inter connector could be ensured.
The committee was informed that the matter have been discussed during 59th meeting of OCCM,
however the fruitful response from MPPTCL still have not been received. It is therefore desired that the
matter may be discussed and suitable result on the matter may be evolved so that system constrained at
Satna area may be addressed.
Representative from MPPTCL informed the committee that it is being proposed to connect one of the
interconnectors from Satna PGCIL to 220 KV S/s Kotar which will relieve the loading of other
interconnectors, but it is under discussion/planning stage and will be intimated to all the concerned entities
once the proposal is approved.

6.8 Delay In Conveying Information of Tripping /Disturbance At Sarni End:- it was informed to the
committee that 220 KV Sarni –Handia line tripped at 17:10 hrs on 15.04.2018 from Sarni Power House. The
line could be normalized at 18:07 hrs on 15.04.2018 after 57 minutes of tripping. The abnormal delay in
normalization of the line was due to delay in conveying the tripping details to Handia substation as well as to
MP SLDC.
The indications of aforesaid lines were received at SLDC after repeated pursuance by SLDC. It is
pointed out that generally observed that whenever tripping/disturbance took place at Sarni Power House,
the details are not conveyed timely, resulting delay in process of normalization. Thus, outage of lines is
increased unnecessarily and hampers grid security.
It is requested that the concerned officials may please be instructed suitably that whenever any tripping
or disturbance occurred on EHV elements, the same should be conveyed with relay indications and all
relevant details to SLDC within reasonable time slot so that remedial action could be taken in due course of
time and could be avoided undesired delay in restoration of EHV elements. As prolong outage of EHV
elements also involved commercial issue therefore MPPTCL / MPPGCL and all utilities are requested to
ensure timely restoration of tripped EHV elements.
Member Secretary OCC requested MPPGCL to instruct the site officials accordingly for fast restoration
of the system.

of officers at each power house looking after telemetry work & also provide the list of spares (PLCC/RTU/MFM etc.)
MPPGCL representative agreed to resolve the above issue at the earliest.
9.5 NON AVAILABLITY OF SOE AT SLDC SCADA SYSTEM
SLDC informed that the problem in receipt of SOE from field is observed. WRLDC vide letters
dtd. 03.05.17 & 15.05.17 intimated that SOE of grid disturbance at 220 KV S/s Mahalgaon & 400 KV S/s Indore is not received in Back-up LDC SCADA/Sub-LDC SCADA system respectively. SLDC is carrying out data validation of various substations periodically & it is observed that SOE from various substations like 400 KV S/s Satpura, 400 KV S/s Astha, 220 KV S/s Damoh, 220 KV Itarsi, 220 KV Barwaha, 220 KV Chhindwara, 220 KV Pandhurna, 220 KV Sabalgarh, 220 KV Shivpuri, 220 KV S/s Tikamgarh, 220 KV S/s Mahalgaon, 220 KV S/s Hoshangabad, 220 KV Shujalpur, 220 KV S/s Badod was not received at SLDC SCADA system. Subsequently SLDC vide letter SE/LD:E&T/200 dtd. 14-06-17 requested MPPTCL to arrange simulation testing for SOE of all RTUs.
Receiving of SOE is very essential for analysis & investigation of major tripping in the grid. SLDC
requested MPPTCL to arrange simulation testing for SOE of all RTU’s in coordination with SLDC
