ITEM No. 1: CONFIRMATION OF THE MINUTES

Superintending Engineer(Opn), WRPC stated that the Minutes of 456TH meeting

of Operation & Coordination Sub-Committee of WRPC held on 13th February 2014 at

GETCO, Vadodara, were forwarded vide letter No. WRPC/OPN/OCC-Minutes/2013-

14/1741 dated 25.02.2014.

1. GM(OS & Comml), NTPC Mumbai vide letter dated 05.03.2014 commented on Item

no 1A(6) of minutes regarding Technical minimum scheduling of NTPC stations wrt to

following paragraph :

Quote:

“In view of above discussions, OCC recommended that in case of schedule is less

than 30% of MCR even after final review by WRLDC as indicated above, then NTPC

either run the NTPC units above 30% of MCR as recommended by CEA to CERC,

even after review the requisition doesn’t match TM, otherwise NTPC is at liberty to

either shut down the units or run the units more than schedule to the extent possible

without oil support, thus over injecting into the grid.”

Unquote:

He requested that the above recorded paragraph of OCC is discordant with 24th

WRPC decision as CEA vide letter dated 12.09.2013 have just sent the

recommendations to Hon’ble CERC which states that the operating capability for coal

fired units can operate at any load without any limits; and minimum load without oil

support is taken as about 30% MCR and operation below this limit need oil support

and it cannot be implemented unless approved by Hon’ble CERC. In addition, higher

forum(WRPC) decision can’t be changed in lower forum(OCC) and therefore

requested for deletion of the paragraph.


Member Secretary, WRPC intimated WRPC agrees with observation of NTPC and

WRPC decision taken in 24th WRPC meeting shall stand till it further reviewed in the

same or any guidelines/regulation issued by appropriate authorities. Therefore parawill

(A) FOLLOW-UP

8.1 QUARTERLY REVIEW OF CRISIS MANAGEMENT PLAN

All the constituents are requested to submit the CMP report for the Third quarter

(October 2013 to December 2013) for the year 2013-14.


8.2 STATUS OF PHYSICAL & CYBER SECURITY IN POWER SECTOR REGARDING

Status of physical & cyber security in Power Sector for the Third quarter (October 2013 to December 2013) have not been received from some of the constituents. Constituents were requested to furnish the latest status.

Shri Samual C. Sciacca, from SCS consulting, LLC USA who was present in IEEE seminar at Mumbai held on 10.3.2014 was specially invited by Member Secretary for giving a brief presentation on cyber security to OCC Members & participants. Shri Samual C. Sciacca expert shared his knowledge with members of OCC.

The sub-committee appreciated the exposure given by Shri Samual C. Sciacca and thanked him for his willful participation.


ITEM NO. 8.3 ADMS IMPLEMENTATION STEP BY GETCO

A pilot project in respect of ADMS have been successfully implemented by GETCO in

11 kV Sadhi feeder (MGVCL ) on 19.02.2014.

SLDC, GETCO submitted a presentation on the same, which is enclosed at annexure-8.3.

ITEMS FROM WRLDC:

ITEM NO. 9.1 : PERFORMANCE OF WR CONSTITUENTS POST THE IMPLEMENTATION OF DEVIATION SETTLEMENT MECHANISM ON 17.02.2014

The IEGC second amendment as well as the Deviation Settlement Mechanism is in

force w.e.f. 17.02.2014. The performance of WR constituents during first 10 days i.e.

from 17th to 28th Feb 2014 comprising of 960 time blocks is illustrated below. Members

may like to analyze and devise suitable measures to ensure compliance to the above

CERC regulations.


Since the decisions in real-time are based on the SCADA data it is now important to

monitor and ensure correctness of drawal / injection as seen in SCADA. The chart

below indicates the difference between the drawal of constituents as seen in SCADA

and as recorded in SEM for the period of 01st Feb 2014 to 16th February 2014. It may

be seen that the significant difference between SCADA and SEM needs to be

addressed by ensuring healthiness of telemetry and periodic validation by the SCADA

team at the respective SLDCs and WRLDC.


Following points were highlighted by the constituents regarding sticking to DSM for

curtailing over/under drawal within limits as specified in IEGC/DSM :

• SLDC are doing their best to manage load/generation as per schedule but as

the margins is very less and due to SCADA data errors, deviations would be

there.

• Persistant underdrawal by Chhattisgarh is a big problem

• In Gujarat, schedules are revised in real time but the the generation is not

controlled within time. CGPL representative expressed that many revisions are

issued to them (as good as 15 revisions a day) and it becomes difficult for them

to achieve technical minimun to full load(wet to dry mode) as per schedule.

• NTPC representative indicated that Mounda unit is under reserve shutdown but

at the same time schedule from Chhattisgarh is there.

After hearing the views of the constituents Member Secretary, WRPC stated that all

efforts for maintaining the drawal as per schedule should be made. Regarding CGPL

problem for ramping generation from wet to dry mode he requested CGPL for submit

an agenda item in ensuing OCC after getting OEM recommendations for ramping

rates.

Committee noted as above.

ITEM NO. 9.2: UNDER DRAWAL BY MAHARASHTRA AND INSECURE OPERATION IN THE GRID ON 27-28 FEB 2014

During late night of 27th Feb and early morning hours of 28th Feb-14, the grid

frequency remained above 50.2 Hz continuously for five hours from 22:52 hrs of 27-

02-2014 to 04:07 hrs of 28-02-2014. The situation was caused due to demand

reduction across the WR and NR on account of widespread rains and persistent under

drawal by Maharashtra during the above period as illustrated in figure-1 below.

Maharashtra Deviation from schedule vis‐a‐vis grid frequency21:00 hrs of 27‐02‐2014 to 08:00 hrs of 28‐02‐2014

MSEBUI FREQ

Deviation from Schedule

Frequency

MW Hz

Several messages were sent from WRLDC control room to SLDC Kalwa directing them to control their under drawal from the grid. Details of these messages is tabulated below.

Sl. No. Message sent to Ref No. Message date and

time

1 SLDC Maharashtra

56/079 27.02.2014, 22:10 hrs.

2 SLDC Maharashtra

3070 27.02.2014, 22:30 hrs.

3 SLDC Maharashtra

3078 28.02.2014, 01:25 hrs.

4 SLDC Maharashtra

3079 28.02.2014, 01:50 hrs.

Despite the above messages, the response from SLDC Kalwa was inadequate in

controlling the under drawal of Maharashtra. Consequently the frequency touched

50.69 Hz at 02:11 hrs. of 28-Feb 2014; the voltage across the grid increased sharply

and there was over injection from WR to other regions. Subsequently as a

contingency measure the drawal schedule of Maharashtra was reduced by 600 MW

by suo motu revision in the requisition of Maharashtra in Korba, Vindhyachal, Sipat

and Vidhyachal STPS w.e.f. 02:30 hrs to 05:00 hrs of 28.02.2014. This was later


extended up to 07:00 hrs of 28.02.2014. It was a near miss situation that could have

been avoided by adequate planning and commensurate actions in real-time. It is

requested that the matter may be taken up at the highest level in MSETCL and a

separate meeting may be convened on the above subject to avoid reoccurrence of

such event in future.

As indicated in opening remarks this incidence need to be studied. Hence SE(O),

WRPC requested to furnish schedule vs drawl figures for all the constituent for 27 and

28th Feb 2014.

The sub committee noted the same.

ITEM NO. 9.3: NON AVAILABILITY OF REAL-TIME TELEMETRY FROM LARGE NUMBER OF STATIONS IN MAHARASHTRA

There are 224 nodes in Maharashtra that comprising of 32 Generating stations and

192 substations. Out of these 224 nodes, 47 locations are yet to be integrated in the

System. Out of the balance 177, the data from nearly 50% nodes are not coming since

last 6 months. Thus in totality data is not available from more than 135 out of 224

stations .i.e. 60 % which is highly alarming. The extremely poor status of telemetry in

the state of Maharashtra has become a security threat. Maharashtra load is touching

17500 MW and there are large number of construction related outages that have to be

facilitated. Further with the formation of the synchronous All India grid there is a need

for close monitoring of system parameters such as the line flows, voltage and grid

frequency. Inadequate telemetry is resulting in severe constraints in real time

operation as well as outage coordination. There have been several instances of line

tripping on high voltage, and SPS operation due to sudden increase in line flows

during hour boundary, or during facilitating planned outage. These events could be

minimized with better supervision if the telemetry is available.

The telemetry issue in Maharashtra has been discussed in the various WRPC forums

wherein it was informed by MSETCL that the problem is due to failure of M/s Tulip

who was the service provider for the communication network. During the month of

August 2013 representative from MSETCL had assured that a new contract was being

awarded and the situation would improve within one month.


SE(O), WRPC requested MSETCL to provide the statistics of progress of provision of

telemetry in various nodes to WRPC/WRLDC on regular basis till its final

implementation.

SE(Tel), MSETCL intimated that work is under final stage & assured that Telemetry

data from Maharashtra stations would be available regularly by end of April 2014.


ITEM NO. 9.4: STATUS OF LINE AND BUS REACTORS AT 765 KV SASAN

The line reactor of 765 kV Sasan-Satna ckt-2 as well as the Bus reactors of 765 kV Sasan bus are yet to be commissioned at Sasan end. In the absence of these reactors, high voltage is experienced at Sasan and nearby stations. Often one circuit of 765 kV Sasan-Satna is required to be opened for voltage regulation. Consequently the reliability of evacuation of generation from two units of Sasan is affected. During 456th OCC meeting, the revised schedule of the above elements as informed by M/s Reliance was as under:

Schedule in formed in meetings

451st OCC 455th OCC 454th OCC

1 Line reactor of 765 kV Sasan-Satna ckt-2

By Dec 2013 By April 2014 By May 2014

2 765 kV Bus-1 Reactor

Jan 2014 By Mar 2014 By June 2014

CE(LD) MPPTCL intimated that visit to SASAN site to check readiness of Line and Bus reactors would be made 2nd or 3rd week of March-14 alongwith representative from NTPC.


ITEM NO. 9.5: CHARGING OF NEW TRANSMISSION ASSET IN THE GRID In order to have better coordination of the transmission utilities with RLDC/NLDC during charging / synchronization of new elements into the grid a communication has been received from NLDC (ref: POSOSCO/NLDC/System Operation/Outage Planning/1239) on 10.02.2014. It has been proposed that


a. Owner of the asset shall submit the request for expected charging/commissioning of new element for the calendar month latest by 5th day of the month to the respective RLDC & NLDC along with status of activities mentioned in the check-list.

b. RLDC shall study the impact of the new element commissioning and based on its assessment of the preparedness of the utility may recommend to NLDC who in turn would examine the issue independently considering pan India grid scenario.

c. After the above, the owner of the new asset shall give its readiness to charge the new element at least three days in advance with current status of activities mentioned in the check list.

Check list is as under

1. List of elements to be charged along with the details of approval of the transmission scheme from the Standing Committee/CTU/STU

12. Output of EL and DR after charging Each document mentioned in check list from Sl. No. 1 to 10 must be attached for sake of completeness and emailed as a consolidated document to the nodal RLDC well before the new element charging date.


Member Secretary, WRPC suggested members (particularly ISTS licensees) to go through the proposal submitted by NLDC, and discuss & revert with suggestions in next OCCM.

The sub-committee noted the same.

ITEM NO. 9.6: OPENING FEEDERS WITHOUT PRIOR INTIMATION TO WRLDC

It was gathered based on the observation from WRLDC SCADA data and subsequent

discussion with MPPTCL that 220 kV Bina (MP)-Gwalior(MP) D/C were taken under

shut down for LILO works at Datia at 09:10hrs on 23/02/2014 for 4 days. The outage

of these lines was neither discussed in OCC and neither was there any intimation to

WRLDC before availing the outage. These lines are included in the important grid

elements list of Western region and prior concurrence of WRLDC is required for

switching these lines. Further these lines form the parallel path to 765 kV Bina-Gwalior

D/C and with the shutdown of these lines the network upstream of WR-NR inter

regional corridor was depleted.

OCC suggested that WRLDC shall circulate list of important STU lines for which

WRLDC concurrence required. WRLDC agreed.


ITEM NO. 9.7 TRIPPING OF 765 KV LINES ON OVER VOLTAGE

Recently several tripping of 765 kV lines have been reported on over voltage. These are indicated below:

1) 765 kV Bina-Gwalior I at 23:58 hrs of 16.02.2014 2) 765 kV Bina-Gwalior I at 20:11 hrs of 14.02.2014 3) 765 kV Satna-Gwalior at 13:00 hrs of 06.02.2014 4) 765 kV Sasan-Satna II at 00:13 hrs of 18.01.2014 5) 765 kV Jabalpur-Bina I at 23:50 hrs of 10.01.2014 6) 765 kV Jabalpur-Bina II at 04:05 hrs of 06.01.2014

PGCIL intimated that as the equipments for 765 kV are rated for 108 %, adopted Stage-I O/V setting for the above lines vary from 106 % to 108 %. As per SCADA data the bus voltage at any of the substations mentioned above had not reached 826 kV during the above incidents.


POWERGRID may examine the above tripping in detail and apprise the OCC regarding the above. In case of issues related with protective relays /field equipment are detected, these may be addressed at the earliest.

Member Secretary WRPC directed WRTS-II(PGCIL), to submit the DR status & complete report including settings to WRPC/WRLDC for further analysis.

PGCIL, WRTS-II representative agreed for the same.

The sub-committee noted as above.

ITEM NO. 9.8: RGMO / FGMO OF MANDATED GENERATORS IN WESTERN REGION
