2014 to December 2014) have not been received from some of the constituents.

The Sub-Committee may like to note and furnish details in respect of above.

ITEM NO. 8.3 UNRESONABLE SCHEDULING OF NTPC VINDHYACHALGM(OS), NTPC Mumbai vide letter no WR-I HQ/OS-COMML/GM/2015 dated 08th January, 2015

requested to discuss the unreasonable schedule at NTPC Vindhyachal station.

1. NTPC units are being given unreasonable schedules for operation. In spite of

repeated requests by NTPC, the schedules are observed to be very low during

night hours and exceeding the capacity of On-Bar units during day hours.

Constituents are giving requisitions ranging from 0 to 100% of their entitlements

resulting into a huge gap between maximum and minimum generation levels.

Because of such un-reasonable schedules, unintentional over-injection as well

12

467th OCCM AGENDA

as under-injection is taking place (the trend did not improve even after the

withdrawal of 2 units of Vindhyachal St-I of 6 x 210 MW).

2. Considering such operational difficulties, the decision was already taken in 24th,

25th & 26th WRPC meetings regarding Technical Minimum scheduling and

methodology for declaration of RSD. The same needs to be ensured.

3. Operationally reasonable schedules and ratio between minimum and maximum

generation levels are required to be ensured as envisaged in IEGC (cl. 6.5.14

of IEGC regulation). This will ensure the integrated operation of the power

system as envisaged in regulation 2.3.1 of IEGC.CE9SLDC), GETCO vide letter dated 06.01.2015(copy enclosed at Annexure-8.3) submitted their

view.


ITEM NO. 8.4 CONVERSION OF NON SWITCHABLE 50 MVAR LINE REACTOROF BINA CKT. 1&2 WITH SWITCHABLE LINE REACTORS AT SHUJALPUR SS

Chief Manager, WR-II, PGCIL vide email dated 07.01.2015 requested for conversion

of non switchable 50 MVAr line reactor of Bina ckt. 1&2 with switchable line reactors

at Shujalpur S/s.

He informed that in the recent trippings of 400kV Bina Shujalpur 1&2 D/C line, it is

observed that during the Dead Time of Auto Reclose cycle, heavy voltage of

magnitude almost equal to normal phase voltage is getting induced in the de-

energised phase. This line is having fixed 50MVAR line reactors at 400Kv Shujalpur

end, whereas at Bina end, 63MVAR switchable reactors are available.

400kV Bina - Shujalpur D/C Line has been commissioned after LILO of 400kV Bina-

Nagda D/C Line at Shujalpur S/s. It appears that after LILO resonance/ over

compensation is taking place. In this regard, it is required to convert 50MVAR line

reactor at Shujalpur end into switchable reactor. The same shall be taken up for

approval of WRPC separately. However, till such time, it is proposed to keep the

50MVAR Line reactors of 400kV Bina Shujalpur#1&2 out of service at Shujalpur end,

as resonance may cause damage to the reactor.

467th OCCM AGENDA

2. Western Region Recovery Procedure-2015

WRLDC informed that a workshop on System Restoration Procedure of Western

Region was organized on 15-Dec-2014 in Mumbai. Around 125 representatives from

Generating Stations, Transmission Utilities, State Utilities, SLDCs, RLDCs, WRPC

and Railways attended the workshop. The healthiness of black start facilities in

Western Region as well as the restoration procedure of the State and WR Regional

power system was reviewed. The summary and action points that emerged from the

workshop are as under:

a. In Gujarat the generating units of AECo and Korba (E) in Chattisgarh

have been de-commissioned. In Maharashtra RGPPL units are under

long outage. SLDC Kalwa representative stated that Koyna Dam Power

House also is not capable of blackstart. Thus AECo, Korba (E), RGPPL

and KDPH may be deleted from the list of stations capable of supplying

black start power supply. (Action: WRLDC / SLDC-Gotri/SLDC-

Kalwa/SLDC-Raipur)

b. In Gujarat, the Mini hydro plant located at lower bank canal (LBC) ofUkai would not be capable of extending start up supply to other thermal

power station in Gujarat. However, the hydro m/c can self-start and feed

auxiliaries of Ukai (H) if the black start DG set of Ukai (H) fails to start

during restoration. Thus Mini Hydro would be designated as a back-up of

Ukai (Hy) hence may be retained in the list of stations identified for

supplying Black start power supply. (Action: WRLDC / SLDC-Gotri)c. Black start Diesel Generator is the most critical equipment for System

Restoration. Therefore, reliability and redundancy of the DG set at the

power stations identified for black start is of extremely important. Even

the existing DG sets may be very old or are unhealthy and may fail at the

time of black start. Thus the respective utilities shall initiate actions to

ensure at least two DG sets at the stations identified for black start.

(Action: All WR utilities)

d. In Mumbai system, Tata Power reported that the black start mock drill of

with an islanded separate sub-system could not be conducted because

of non-availability of permission for bus shut down and power supply

interruption (that may be required for a short duration during the drill).

17

467th OCCM AGENDA

However Tata Power confirmed that the healthiness of the DG sets are

regularly checked on weekly basis. SLDC Maharashtra may coordinate

with ALDC TPC to conduct black start mock drill at the earliest

opportunity, when the shut-down of the bus is taken for maintenance.

(Action: SLDC Maharashtra/ALDC TPC)

e. CGPL_UMPP (830 MW units) is connected only at 400 kV level. CGPL

may explore the possibility of drawing auxiliary power supply through

220 kV Nanikhakar s/s of GETCO. Similarly, the new IPP thermal

generating stations located in Chattisgarh are mostly at EHV level. In the

absence of connectivity at lower voltage level and large distance from

the black start sources, severe high voltage constraints may be

experienced while extension of start-up supply to these stations over the

400 kV lines or 765 kV lines. These power stations may explore the

possibility of having a contingency connection at lower voltage level that

could be used to avail power supply for unit auxiliary under system

restoration. The concerned generators may also explore possibility of

availing black start supply from with Captive Power Stations (in their

vicinity) having islanding scheme or Black start generator. (Action:

CGPL/IPPs in Chhattigarh area/SLDC-Gotri/SLDC-Raipur/WRLDC)

f. Several generating station having black start facility are Gas based

stations availing Gas feed from Gas pipelines of GAIL/ONGC/Others.

During a total blackout the availability of gas at appropriate pressure

may be a constraint which may delay/stall the system restoration

process. The respective Gas Stations shall therefore examine this

aspect in coordination with the gas supplier. (Action:

Kawas/Jhanor/Uran/GIPCL/Sugen/ SLDC-Gotri/SLDC-Kalwa)

g. Railway traction was identified as priority load during SystemRestoration. Traction supply being single phase 25 kV AC may pose achallenge due to unbalancing/Negative Phase Sequence Currents. Aseparate discussion shall be initiated with representatives of CentralRailways, Western Railways and South-east Central Railways and Stateutilities/SLDCs/WRLDC/WRPC to deliberate on this issue. (Action: AllWR constituents/WRLDC/WRPC).The revised Recovery Procedure forWestern Region is available on the WRLDC website.

467th OCCM AGENDA

3. Mock Black Start Exercise in Western Region

As mandated by IEGC the black start capable units need to conduct mock blackstart exercises once in every 6 months. Western Region has 29 generatingstations with black start capability. As per the information available with WRLDConly 10 stations have completed the Mock exercise in the full year 2014. Tentativeschedule for all stations have been made for the period Jan’15 to June’15 which isenclosed at Annexure- 9.4


4. Extension of start-up supply to power stations located in remote areas

During the 465th OCC meeting contingency arrangement for availing start up power byCGPL Mundra from 220 kV Nanikhakar was discussed. It was decided that a jointteam of GETCO, WRTS-II and CGPL officials would visit the site and assess thefeasibility of connectivity between CGPL Mundra and 220kV Nanikhakar line fordrawing start-up supply under contingency situation.It was again emphasized in 466th OCC to have a visit by joint team of GETCO, WRTS-II and CGPL officials and find the feasibility of connectivity between CGPL Mundraand 220kV Nanikhakar line.Further in 465th and 466th OCCM, the SLDCs were advised to identify captive powerplants which could extend the start-up supply during blackout.The required format was shared by WRLDC with all SLDCs. The details of captivepower plants in Gujarat and Chhattisgarh are received but the same is pending fromMadhya Pradesh and Maharashtra.


5. Revival of Pump Storage Plants in Western Region

Western region has Pump storage plants in following places.

4 Ghatghar 2x125=250 working

19

467th OCCM AGENDA

Though Western region has substantial potential of total1840 MW of capacity, only

Ghatghar of 250 MW pump storage plants are operating. Since the energy gained

from Pumped Storage Plants is less than the energy input, it is necessary that off-

peak power to be used as input may be available at reasonable tariff for making the

Pumped Storage Plant commercially viable.


6. Review of Limiting constraints for Import from Grid by Western RegionStates

During the past OCC meetings it was decided to have joint study with other SLDCs to

identifying measures to enhance import/export limits from the grid. Study of

Maharashtra system was conducted by WRLDC and forwarded to SLDC, Kalwa.

Likewise WRLDC has also forwarded a preliminary study report on 11th November

2014 to SLDC, MPPTCL regarding Import Capability of Madhya Pradesh control area.

The need for assessment of import ATC was also emphasized in a meeting taken by

Member (GO&D), CEA on 29th Oct 2014. Relevant extracts are as under:

The need for assessing the TTC/ATC was also emphasized in 13th FOLD meeting

held on 11-Dec-14. Wherein all SLDC members of FOLD and member from RPC were

present. The relevant extract from Minutes of meeting given below:-

Quote

“After deliberations, it was agreed that all SLDCs would make efforts to assess

TTC of their control area as well as provide periodic feedback regarding intra-

state congestion. It was also suggested that TTC/ATC of each state control areacan be discussed in the respective OCC meeting so that the constraints in any

transmission corridor are identified and highlighted so that its mitigation

receives due attention.”

20

467th OCCM AGENDA

Unquote

Consequently, one day workshop on TTC/ATC was conducted with nominated

representatives from SLDCs and WRPC on 17-Dec-14 at WRLDC, where

methodology of TTC/ATC computation was explained and the need for computing

TTC for each state control area was emphasized. A hands on training was given to all

participants on the study cases prepared for ATC computation of Maharashtra and

Madhya Pradesh.

It was proposed that nominated persons would compile the data required and conduct

the simulations for computing TTC/ATC for each state control area and may approach

WRLDC on suitable dates for joint sessions and finalizing the ATC.


7. Real time security desk at SLDC.

Enquiry Committee on Grid Disturbance on 30th and 31st July 2014 had

recommended for one real-time security desk in all the shifts at each RLDC and

NLDC. Subsequently, the task force on Power System Analysis under Contingencies

had also recommended load despatchers at regional and national level to carry out

load flow, contingency and stability studies corresponding to real time network

conditions. Accordingly, a real time security desk has been made operational at NLDC

and each RLDC with following functions:

i. Offline simulations in real time

ii. Steady State and Dynamics

iii. Assessment of real time transfer capability under normal conditions and

under contingencies

iv. Tuning of state estimator and topology correction in Energy Management

System (EMS)

v. Real Time Contingency Analysis

It was suggested in 13th FOLD held on 11-Dec-14, that each SLDC shall also make

real time security desk operational in each shift. PSS/E simulation software is

available with each SLDC which should facilitate both operational planning and

studies in real time.

21

467th OCCM AGENDA

Subsequently, One day workshop on Tuning of state estimator and topology

correction in Energy Management System (EMS) was conducted on 8-Jan-15 at

WRLDC by Dr NDR Sarma, ERCOT. SLDC,GETCO representatives attended at

WRLDC and SLDC, MP and Chhattisgarh representatives attended through VC.


8. Testing of SPS envisaged for SR-NEW grid operation

The matter regarding inadequate participation of generators envisaged for SPS

related with SR-NEW grid synchronization was discussed in previous OCC as well as

in PCM. POWERGRID representative intimated in 27th TCC/WRPC that the signal had

been extended to the envisaged generators in Chattisgarh. A mock trial of SPS was

conducted on 01st December 2014 wherein signal was sent from 400 kV Raipur and

result was shared with the members in 466 th OCC.
