The action taken in this regard may intimated.

5.2 Over voltage settings of 400 kV lines

In earlier OCC/PCCSC Meetings the matter regarding over voltage settings of 400 kV lines in the Region was discussed.

5.8 NPC/Implementation of Enquiry Committee The second meeting was held on 16th July 2013. The following issues had been deliberated in the NPC meeting.

5.8.1 Implementation of measures to prevent Grid Disturbance

A. Third party Protection Audit:

In the Second NPC Meeting, the following was deliberated:

CEA would be seeking supplementary information from the States shortly on the DPRs submitted by them to bring some uniformity therein.

It was agreed that the DPRs received from the States would be treated as approved from their respective managements.

As per the consolidated DPR submitted to MoP funding from PSDF has been proposed as 20% keeping in view the amount parked in PSDF. This may vary depending upon the amount approved by MoP/PSDF Management Committee and CERC Regulations for PSDF were also in the process of review.

It was decided that the States would immediately take up renovation and up gradation of protection system including switchgears at their substations as mentioned in their respective DPRs without waiting for the funds from the Centre. As the funds become available from PSDF, the same would be distributed to the States as per the guidelines /regulations in force.

In the Special TCC meeting held on 21st August 2013, it was noted that 20% funding proposed from PSDF was felt to be inadequate by the states. States also brought to attention the acute resource crunch being faced by them. The amounts required for renovation and up gradation works had not been factored in the ARR projections furnished to the respective SERCs. The utilities thus requested that the 20% funding proposed be kindly reviewed by CEA and requested that the same be modified to 100% funding. This would ensure completion of the schemes and ensure grid security in shortest possible time. SRPC & SRLDC stated that renovation and up gradation works should be taken up immediately by the utilities without linking the same to any funding etc, since they were required functionally.

B. Reactive Power Planning

In the Second NPC Meeting, it was decided that all States would carry out reactive power planning not only transmission level but also at distribution level and prepare schemes to maintain voltage profile as per relevant Regulations/Standards. The schemes would be forwarded by the States to the Power System Wing of CEA under intimation to the NPC Secretariat at the earliest. Further, execution of the approved schemes would be taken up by the States without waiting for funds from PSDF.

Agenda Notes for the 87th OCC Meeting to be held on 11.09.2013 Page 4

In the Special TCC meeting held on 21st August 2013, it was noted that all the constituents observed that they would rework the scheme including distribution level and would apprise their management in this regard. They stated that full funding should be made through the PSDF.SRLDC and SRPC stated that the schemes should be taken up without linking it to any funding etc.

C. Ensuring proper functioning of UFRs and df/dt relays In the Second NPC Meeting, it had been decided that all SLDCs and RLDCs would upload the details of feeders to be tripped through the UFRs and the expected load relief at different frequency levels in their respective States/Regions on operations of UFRs. It was also decided that RPCs would send inspection report of healthiness of UFR and df/dt regularly on a quarterly basis to NPC Secretariat.

D. Islanding schemes In the Second NPC Meeting, CEA had requested all the RPCs to submit the details of progress of preparation/approval/execution of islanding schemes to NPC Secretariat regularly on fortnightly basis.

In the Special TCC Meeting held on 21st August 2013, it was noted that S1-S2 islanding scheme was to be completed by August 2013. Other islanding schemes would be completed by October 2013.

5.8.2 Reporting the Status of implementation of the recommendations of the Enquiry Committee

Status as on last day of the month to be forwarded by 3rd day of the following month, and that as on 15th of the month to be forwarded by 17th of the month All the constituents were requested to furnish timely status updates.

5.8.3 Review of Zone 3 Philosophy In the Special TCC meeting held on 21st August 2013, it was noted that PGCIL had reviewed and implemented revised Zone-III settings for inter-state lines wherever required. MS I/c, SRPC had informed that complete information had been communicated to PGCIL.

5.8.4 Ring Fencing of Load Despatch Centers

In the Second NPC Meeting, it was decided that inputs in regard to status of implementation of Pradhan Committee Recommendations for ring fencing of the SLDCs would be collected by the RPCs from the States and forwarded by the RPCs to NPC Secretariat every month.

In the Special Meeting held on 21st August 2013, this issue was discussed and constituents expressed their views on the same. It was noted that ring fencing had to be adopted in totality so as to achieve desired autonomy.

5.8.5 Implementation of CEA Regulations

In the Second NPC Meeting, it had been decided that as a first step, all the power utilities be sensitized on CEA Regulations through workshops in regional fora. After completion of awareness phase, the violations of CEA Regulations could be discussed and minuted in RPC meetings and persistent violations could be reported to Hon’ble CERC by CEA/RPC for perusal/reference :

In the Special TCC Meeting held on 21st August 2013, all the constituent States agreed to implement AUFLS with four stages of frequency viz. 49.2, 49.0, 48.8 & 48.6 Hz. As a first step towards the same, setting on feeders of current stage – I & II would be changed to 49.2Hz and 49.0Hz within two weeks. The setting of Stage – III will remain as it is till the procurement of additional relays required to adopt four stages of setting.

5.8.7 Methodology for determination of quantum of load for AUFLS in different regions

In the Second NPC Meeting, all the Members of NPC as well as POSOCO agreed that the quantum of load shedding for NEW grid under AUFLS as worked out in the agenda was in order and the same could be communicated by NPC Secretariat to all the RPCs for implementation with load shedding quantum rounded off to the nearest ten. Same methodology could be adopted to determine the quantum of load shedding at four stages of frequency based on the power number for SR grid and communicated to SRPC for implementation. It had also been agreed that the entire AUFLS scheme would implemented in a maximum period of three months by all the RPCs.

Based on the communication received from CEA vide letter dated 6th August 2013 (Annexure-V B), State-wise Break-up of the UFR quantum (Annexure-V C) to be provided at each stage was presented. It was decided to implement the first two stages by 7th September 2013 and the balance stages would be implemented by 15th October 2013. It was also noted that the balance feeders would be kept intact at the original set points.
