(1) CM, WRLDC informed that there was a planned bi-polar outage of Talcher-Kolar HVDC (ER-SR) on 18.12.2011 and single pole outage of the same on 17th and 19th December 2011. As such 18.12.2011 WR shall not plan any major line outage from security point of view.
(2) SE, SLDC,MSETCL had planned 220 kV TAPS-Borivali presently D/c outage for two hours on 27.12.2011 to attend to work at Borivali in the early morning hours (0400 – 0600). OS, TAPS 1 & 2 requested to take this outage subsequent to the restoration of 220 kV TAPS-Boisar, otherwise both circuits from TAPS towards Maharashtra would be out and this would cause an avoidable alert in plant operation at TAPS. MSETCL stated that the restoration of 220 kV TAPS-Boisar was expected around 25th December 2011 and agreed to plan the outage of TAPS-Borivali afterwards.
(3) SE(WRPC) stated that the line maintenance plan from some of the utilities is received late and sometimes change in the plan arising due to some constraints requires some time to properly work out the suitability for outage, which can be avoided if the plan is received by WRPC early. Further certain utilities propose outages more than one month in advance but in the next month most of these outages are deferred or even cancelled. CM, WRLDC stated that some utilities' requests for line outages in real time which are not of emergency nature but routine in nature or even crossing related work ( but not proposed in OCC). Member Secretary, WRPC stated that as per IEGC Transmission Line Outages must planned Annually and reviewed during the year on

quarterly and monthly basis. All concerned utilities are aware of the plans and should attempt to follow the same so that the grid operates in a secure manner. CM, WRLDC stated that with the expansion the grid, emergence of Power Exchanges, Inter Regional Transfer Capacity etc must be planned and stated in advance which cannot be unilaterally cancelled by any utility. If any deviation in the same is required the same shall be with prior permission of RPC and RLDC. As such the OCC members after discussion decided and agreed to the following:
(a) Considering that the OCC meeting is called in the second week of a month the Planning of outages pertaining to Transmission elements (lines/ICT) in the OCC shall be done from 20th of the current month to the 19th of the next month.
(b) The utilities proposing to avail line maintenance shall submit their plans to WRPC by the 4th of every month and outages received later need not ordinarily be considered by WRPC for planning in that month.
(c) WRPC in consultation with WRLDC shall prepare a tentative plan for the outages which shall be discussed and finalized in the OCC.
(d) The Utilities were requested to send the plans for outages for the period January 20th to February 19th by the 4th of January 2012 to WRPC and continue the practice, henceforth.

The sub-Committee discussed and suggested that same may be discussed by NTPC with constituents in commercial committee meeting scheduled to be held in 23rd December 2011 at WRPC.
• ADDITIONAL ITEMS PROPOSED BY WRLDC
1. Workshops using REC charges GM, WRLDC stated that there is a need to provide awareness in the subjects of timely importance to engineers and the funding of the same can be availed from Reactive pool fund. It was proposed to conduct workshops in the following fashion:
a) There will be four workshops in constituent States + one at Mumbai each costing around 5 lakhs. The total cost will be around 25 lakhs. The subjects identified coverage in all the workshops: i) FGMO ii) Connectivity & other regulations iii) POC iv) Security & reliability v) Renewable vi) Interregional TTC/ATC & congestion management vii) Smart Grid viii) Demand side management ix) Workshop on reliability coordination at Mumbai x) System Studies xi) Protection Aspects xii) WAMS
b) Black start workshops in the constituent states plus one each at NTPC, ISP, SSP &
NPC totaling 8 Nos.workshops. Each work shop will cost about 1.5 lakhs. The estimates for above workshop were based on similar workshops conducted in ER & other regions. The committee discussed and recommended that the above workshops can be conducted for the benefit of the system engineers and the same can be put up for WRPC for its approval.
The sub-committee noted as above 2. Reactive capability testing of generators GM, WRLDC stated that as discussed during 429th OCC constituents may like to furnish reactive capability testing programme for their units. All generators connected to 400 KV grid are encouraged to carry out reactive capability testing – at least three in a month based on the schedule approved by OCM. In this regard, following points may be noted:
a) Gross Reactive Power Capability (of a generator or generating facility)- The maximum lagging and leading reactive capability at the generator terminals and at a specified gross Real Power output for a specific seasons capability period.
b) Net Reactive Power Capability (of a generator or generating facility) – the Gross Reactive Power Capability adjusted for any applicable losses and auxiliary loads
430th OCCM MINUTES
14
incurred up to the point of interconnection ad at a specified Gross Real Power output for a specific seasonal capability period.
c) Lagging (over excited) reactive power test should be conducted for a minimum of two hours and leading (under excited) reactive power test for at least one hour.
d) Testing should be conducted while maintaining close to scheduled voltage on the system bus and coordination with other units may be necessary to maintain schedule voltage
e) All protective relays should be in service along with limiters (OEL & UEL) and AVR in automatic voltage regulator mode.
f) Reactive capabilities of generators are often limited by tap position o generator transformer, station transformer and unit auxiliary transformer. These tap settings need optimization and WRLDC would carry out system studies for tap optimization for the generators.
g) All generating stations connected to 400 KV grid may furnish tap position data, loads on station transformer and unit auxiliary transformer and capability cures to WRLDC.
A write up on Reactive capability testing of generators is enclosed at Annexure-III. WRLDC would furnish detailed formats to those generators slated for testing. During the OCC the members discussed and initially the following generators (preferably connected to 400 kV or catering to reactive power loads) were proposed for Reactive Capability Testing NTPC: One 210 MW and /or one 500 MW unit at VSTPS MPPTCL: SGTPC 500 MW unit MSPGCL: SE(LD) stated that they shall furnish one location in discussion with MSPGCL CSPGCL: Korba(W) one unit GETCO: Shall discuss the issue and inform WRPC. 3. Low Frequency Oscillations in NEW grid GM WRLDC stated low frequency oscillations in NEW grid were noticed on 30 Nov, 2011. NLDC is analyzing the same and had requested SLDCs for data regarding system conditions at that time. Constituents were requested to furnish the same. GM, WRLDC stated that there were certain incidents like a fault and unit tripping in Northern region antecedent to the disturbance that resulted in low frequency wide area oscillation of about 0.3Hz involving WR versus NR and ER. The oscillations lasted for about 6-7 minutes and damped out. He stated that frequency jerks should be avoided as far as possible to avoid such condition. SE (Opn), WRPC informed that oscillations are noticed in power systems whenever the damping at certain modes is inadequate. The damping can be improved by tuning the PSS on generators in the vicinity so as to enhance damping component of the Torque of the generator without destabilizing synchronising torque. This would enhance damping available for inter area modes which is the principle behind PSS Tuning exercise was carried out in WR in consultation with IIT-B. The GEP ( Generator-Excitation-Power System) Transfer functions contributes to deciding the eigen values and as such a practical and economical way to avoid the oscillations is to carry out exercise of PSS Tuning in other regions similar to the way it has been carried out in
430th OCCM MINUTES
15
WR. So far in WR 24 units of (200 or 500 MW capacity) have PSS Tuned and in ER about 8 under the exercise. Further there could be more units with DVR which might have PSS Tuned on it. It was suggested to WRLDC that similar exercise in other regions could be helpful in damping out the occasional low frequency oscillation problem observed in the NEW grid as above.
8.11 RGMO Analysis:
WRLDC representative informed that they are regularly reporting the performance of
RGMO response in the OCC forum. Further he recalled the CERC order on RGMO as quoted below:
CERC IN SUO-MOTU PETITION NO- 191/2011 DATED 04-10-2011 HAS ORDERED AS BELOW FOR THE GENERATORS LISTED IN THE ORDER.
“4: All the respondents are directed to explain by 10.10.2011 the reasons for not switching over to the restricted governor mode of operation and to show cause as to why appropriate action under the Electricity Act, 2003 should not be initiated against the respondents for non-compliance of the provisions of the Grid Code”. The generators in WR are requested to go through the order and act accordingly. Out of 77 eligible units (15,956 MW), there are 35 hydro units (2,786MW) and 42 are thermal units (13,170MW). The table shows the break up of analysis of 77 units, carried out during November-2011.
RGMO (17) 4255 MW FGMO (2) 750 MW
NORESPONSE (32) 9035 MW NOT RUN (11) 1375 MW NO DATA (1) 250 MW
NO TELEMETRY (14) 291 MW WRLDC stated that 96 units (14350 MW) have informed that there are some problems in implementing RGMO. WRLDC requests SLDCs to take up with these generators for RGMO implementation. WRLDC intimated that generators were requested to approach CERC in case the problems continue to persist before the problems get cleared and RGMO made operational that generators may intimate nature of problems faced in implementing RGMO. WRLDC intimated that Out of 188 (31,346 MW) eligible units telemetry is available for 157 units (30,410 MW). The other details are enclosed in Annex 8.11. WRLDC were requested to get the telemetry availability expedited.
The Sub-Committee noted as above. ITEM NO. 9: DATE AND VENUE OF NEXT OCC MEETING
