The 64TH meeting of Operation & Coordination Committee of MP was held on 09th July 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 64th OCCM of M.P. Chairman OCC stated that during last two months the voltage, frequency and grid parameters were well within limit and grid operated in smooth, safe & secure manner. He also informed that during the second fortnight of May 2018 there was an abrupt/unexpected increase in demand and at that instant the thermal generators were under maintenance, but fortunately increase in wind generation of about 1400-1500MW supported in managing the increase demand. He also stated that Hydel power stations also helped TO mitigate the increase demand and he appreciated the efforts of MPPGCL, MPPMCL & NHDC for managing the Demand.
Further chairman OCC informed the committee that CERC has notified a draft regulation on “Deviation Settlement Mechanism and related matters-Fourth Amendment Regulations, 2018” & requested all the entities to review it & provide their comments if any. He informed the committee that at present UI rate at 50 Hz is fixed and has been decided according to the coal rate of pit head generating stations in 2014. In this draft regulation it has been proposed that UI rates will be market driven and UI rate at 50 Hz will be the daily average rate of the exchanges which has traded, more that 80% for the previous day and if the there are no exchange having trading of more than 80% then the UI rate will be calculated by taking the weighted average of all the exchange rate. Also, at 50.05 Hz rate will be zero, at 50.00 Hz rate will be according to the exchange and at 49.85 Hz rate will be Rs8.24/kwh. Secondly, at present the provision for sign reversal of deviation is in every 12 time block and there is no penalty for it, but as per the draft regulation the sign reversal of deviation shall be required to be done in every 6 time block by each entity and entity failing to do so will be penalized by 20% of daily DSM as additional charges. Further if there is deviation (O/D, U/D) of more than 3% in Discom energy in a day then 20% of daily DSM will also be imposed/penalized as additional charges on Discom. Similarly, in case of generators if the variation or deviation is more than 1% then they will also be penalized by 20% of daily DSM. Also at present the cap rate for generating stations is fixed i.e., 3.034paisa/kwh, but according to draft regulation it is proposed that the cap rate for generating stations will also be variable as per the draft regulation. He requested all the Discoms, Generating Companies & MPPMCL to furnish their comments if any.
Shri R.A.Sharma Member Secretary OCC & Addl. Chief Engineer, SLDC welcomed all the guests and
participants for 64th OCCM and requested all the participants for formal introduction. He has appreciated the contribution of all the entities in safe, secure and economical grid operation.

Minutes of 64th OCC of MP 8
implementing grid connected roof top power programme. As a sequel to above roof top power plant have
been installed in government building as well as other prominent buildings. Presently the amount of roof top
generation is not available with SLDC. It is felt that the installed capacity of solar roof top plant, be
considered for modeling of power system network in PSS system. It is intimated that now a days PSS
software are being used for study purpose of power system network for future planning and operation of grid. It is therefore desired that region-wise-District wise quantum of grid connected solar roof top plant
(Region-wise) installed in your Discom may please be provided to SLDC so that the above quantum of
solar roof top installed in the system may be accounted for and updated in PSS power system network.
Monthly region-wise-District wise updation of roof top solar, in each Discom jurisdiction may also be
provided regularly to SLDC in the first week of every month, for keeping the PSS update.
The management has desired that the compliance on the above matter may please be adhered to.
Member Secretary OCC stated letter have been issued to all the Discom for providing desired
information and therein it is is requested to submit the required details. Further it was also requested that the

The members have noted the points.
6.4 One Hour 20 minutes interruption to 220 KV substation Shahdol on dtd 01.06.2018 and non-reporting thereof: - It was apprised to the committee that at 16:53 hrs on dtd 01.06.2018, AE 220 KV
substation Shahdol had forwarded shutdown proposal on 40 MVA 132/33 KV transformer to attend hot point
on 33 KV main bus R-phase isolator jaw. Subsequently it was gathered that 40 MVA 132/33 KV transformer
had already been hand tripped at 16:30 hrs without obtaining code from SLDC. The Executive Engineer
(Testing) MPPTCL Shahdol was requested to furnish the details of incidence took place. However, Shahdol
substation was trying to hide the facts and 40 MVA transformer was charged without obtaining code from
SLDC. Thereafter at late night hours it was gathered that 20 MVA 132/33 KV transformer at 220 KV
substation Shahdol was also hand tripped at 16:30 hrs (01.06.2018) along with 40 MVA transformer.
Therefore, this caused one hours 10 minutes interruption to Shahdol substation. Nevertheless, long duration
interruption to Commissioner Head Quarter is not desirable, moreover the facts were concealed. It was aso mentioned in the meeting that keeping the EHV elements out of service without permission
of SLDC is violation of grid code. Obviously, the EHV Elements could be hand tripped without obtaining
code from SLDC in case of exigency but it should be informed immediately to SLDC and Elements should
have charged after obtaining code from SLDC. It was also informed to the representative of MPPTCL that it
is generally observed that the EE (Testing) Shahdol is intended to indulge in disputes rather than addressing
the real issue. It is therefore MPPTCL was requested to address the issue and suitable directives may be
issued to concerned official to adhere with provisions of grid code.
Representative from MPPTCL informed the committee that the explanation has been call from Shahdol
and the details will be submitted shortly.

Sarni – B Ph. Zone-1, Location – 16.08 KM
The line could be normalized at 16:05 hrs on 09.06.2018 after 01 hour 15 minutes of tripping. The
committee was informed that that abnormal delay had been done for normalization of above line. In the
above context, it have been pointed out that it is generally observed that whenever any tripping took place at
Sarni Power House, abnormal delays were noticed for normalizing the lines, on plea of yard checking/
testing etc.
Accordingly MPPGCL representatives were requested that the concerned officials may please be
instructed 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 and system
should be normalized promptly in due course of time so that undesired delay in restoration of EHV elements
could be avoided. The prolong outage of EHV elements also involved commercial issues therefore it is
desired to arrange to ensure timely restoration of tripped EHV elements.
Representative from MPPGCL stated that the control room for 400 KV STPS – Ashta ckt – I & II is
separate and is situated at a distance from the existing control room and there are no staff posted at Asha
control room. Hence on occurrence of trappings generally delay took place , as staff rushed from main
control room for taking further course of action.
The MPPGCL was requested to arrange availability of staff at separate control room of 400 KV STPS-
Ashta ckt - I & II at STPS so that such occurrence could be avoided. .
