(SOAP) held at SLDC, Raipur on 28.01.2016

The 13th meeting of Chhattisgarh State Operation and Protection Sub

Committee of SGCC was held on 28th January 2016 at SLDC Conference Hall.

The list of participants is enclosed in Annexure-I.

Shri. W.R Wankhede, Chief Engineer (SLDC) welcomed all the

participants of 13th

SOAP meeting. He further congratulated all the participants,

on successful completion of first year of SOAP Meetings.

Item no. 1 Confirmation of minutes:-

minutes of 12th SOAP meeting are hereby confirmed.

Sub Committee agreed and noted.

Item no. 2 Review of system operation during the month of December

2015:-

Presentation and the performance of Thermal Stations and

Transmission System by SLDC is enclosed in Annexure-II.

Sub Committee noted.

Item no.3 State Energy Audit (SEA) Data:-

The data related to SEA report were already submitted by the

concern offices before the meeting was held.


Item no. 4 Outage planning for the month of February 2016 & March

2016:-

Outage planning of Transmission feeders, Power transformers for

the month February 2016 & March 2016 submitted by O/o CE

(T&C) is enclosed in Annexure III.

Once again the representatives were requested to submit the

planned outages for next 2 months by 26th of every month so that


the intra-state outages are discussed & finalize in the SOAP

meeting on 28th

of every month.


Item no.5 Real Time Telemetry:

As intimated by the representative of CE (T&C) CSPTCL, the Real

Time Telemetry of 220 KV Churi & Bishrampur is not available

due to non availability of communication and could not give any

time line for its availability. Representative of CE (T&C) has been

once again asked to look into this issue on priority. The committee

felt that the telemetry of 220KV Churi & Bishrampur cannot be

ignored more from the point of view of secured grid operation.

As per the requirement of Grid Code the Voltages of Most

of the 220 KV substations are out from long time hence its

complete Voltage profile report could not be submitted to CSERC

& STU. Both the offices of CE(T&C),CSPTCL & ED(O&M:Gen)

CSPGCL are requested to arrange the telemetry of Bus voltages on

priority.

Further the MVAR telemetry of 400 KV & 220 KV needs

to be verified & made available to SLDC for maintaining the

Voltages in limits in day to day operation and system study

purpose.

This issue is being intimated to the representative from

O/o CE(T&C), in all previous meetings but there is no change in

the status of Real Time Telemetry as mentioned above.


ACTION: CE (O&M: Gen), CSPGCL, Raipur & CE (T&C) CSPTCL,

Raipur


Item no. 6 Status of FGMO {Free Govern Mode Operation } in thermal

units as on 28.01.2016:
