Item no.18: Any other Item – Following additional items are received for

discussion/noting in the 78th CCM -

18.a. Correction of Time drift in energy meters

WRLDC vide email dated 17.07.18 (copy enclosed at Annex 18) informed that time drift

in Energy meters may result in computational errors in energy accounts. As per the

technical specifications of SEM, the DCD could be used to carry out corrections in SEM

clock by accelerating /retarding the SEM clock by 1min / week. The list of meters where

time drift has been reported / observed is enclosed as Annex-18.a

Concerned utilities to check the meter clock every week and

retard/advance the clock if required. The procedure for time drift correction

through DCD in L&T, Secure and Elster Meters is enclosed.

POWERGRID is carrying out testing of SEMs which are more than 5 years

old. Time drift correction in the SEM could be done along with the testing

of meters.

Committee may like to discuss

18.b. Submission of Test Reports of Special Energy Meters in Western

Region

WRLDC vide email dated 17.07.18 (copy enclosed at Annex 18) informed that WRTS-II

vide its letter ref. no. WRTS-II/VDR/AM/SK/260/1002 informed that testing of SEMs

more than 10 years old has already taken up. It was understood that the testing has

already completed at various locations in WR-2. POWERGRID to share the Meter Test

Report with the concerned beneficiaries as well as with WRPC and WRLDC.


18.c. Relocation of Check meters for ISGS evacuated through dedicated

lines

WRLDC vide email dated 17.07.18 (copy enclosed at Annex 18) informed that the

redundancy of interface energy metering of ISGS evacuating through dedicated lines

was reviewed. It was observed that even after removal of interim LILO of ISTS lines /

commissioning of dedicated lines, the check meters are yet to be shifted from the

Generating station to the interface points (at POWERGRID substation). Vide letter ref.

no. WRLDC/SO/Metering/774-90 dtd. 03.07.2018, WRLDC has advised relocation of

meters for twelve generating stations (IPPs). The list is enclosed as Annex-18.c. This

relocation is essential for ensuring redundancy of measurement and for better validation

of main meter data (at the interface point) used in energy accounting.

Concerned Utilities to update the progress.


18.d. Revision in metering points at Solapur (PG) for computation of

MSEDCL drawal


present metering philosophy at Solapur (PG) is as below:

At present, active energy drawal of Maharashtra from Solapur (PG) is computed through the

summation of ISTS elements (10 in nos.) at the 400 kV bus (i.e.

M1+M2+M3+M4+M5+M6+M7+M8+M9+M10) (total 10 meters)

It is proposed that Maharashtra active energy drawal at Solapur (PG) may be computed from

the summation of drawal through ICT-1, ICT-2, ICT-3, 400 kV Solapur-Solapur (Lamboti) line

and Statcom auxiliary drawal (i.e. = S17+S11+S12+S13+S18) (Total – 5 meters). As total no. of

meters will be half as that in present scenario, the meter error will be minimized. Commercial

Committee to endorse

1. Installation of one standby SEM on 400 kV Solapur-Lamboti line at Lamboti end

2. Revision in the formula for computing MSEDCL drawal (Active & Reactive) from

Solapur (PG)


18.e. Inclusion of SEMs on tertiary winding for computation of reactive

Energy drawal

WRLDC vide email dated 17.07.18 (copy enclosed at Annex 18) informed that back up

station supply at several POWERGRID substations is through the tertiary winding of

765/400 kV. The discom of the host State has also installed their energy meters for billing.

The SEMs installed on the tertiary side of the ICT are already added in the active energy

reports of the respective state. Committee may deliberate on the inclusion of SEMs

installed on tertiary side in computation of Reactive Energy Drawal.

18.f. Re-installation of SEM meter at tertiary side of 765/400/33 kV ICT-2 at

Warora (PG)

WRLDC vide email dated 17.07.18 (copy enclosed at Annex 18) informed that SEM

(NP-8976-A) installed at the 33 kV side of the 765/400/33 kV ICT-2 (used in

Maharashtra drawal) was removed by MSEDCL/Warora(PG) on 19.06.18 without taking

permission from WRLDC metering department. After removal of SEM, the energy drawn

from tertiary at Warora could not be added to Maharashtra drawal due to non-availability

of data.

It is required that SEM shall be reinstalled so that energy drawn by Warora (PG) for

meeting local substation demand may be added to Maharashtra drawal. MSEDCL has

already installed their own meter to bill Warora (PG) for this drawal.

MSEDCL / POWERGRID to take corrective action.


18.g. Installation of standby energy meters at Seoni, Kanhan and Mansar

WRLDC vide email dated 17.07.18 (copy enclosed at Annex 18) informed that WRLDC

vide its letter dated 03.01.18 had advised for installation of check meter at Pench HPS

and Standby meter at remote end. The check meters had been installed at Pench statin

by POWERGRID and main meters have been replaced with new meters as per the

following details.

POWERGRID to apprise the CCM regarding the plan for installation of standby

energy meters at Seoni, Kanhan and Mansar end.


18.h. Interface Energy Meter Data Discrepancies


discrepancy report of SEMs is being forwarded to WRPC secretariat every week along with

the processed energy meter readings. These details are also posted on the WRLDC

website. The summary of these discrepancies is provided below:

a. 400kV side of ICT-2 at Aurangabad(PG)

The energy meter (NP-8716-A) data of 400kV side of ICT-2 at Aurangabad(PG) was corrupt

for the period 02.04.18 to 30.05.18. Therefore, 400 kV side data was replaced with the 220

kV side standby meter data.

b. 400kV Kansari Line-1 at Veloda

The energy meter (GJ-2971-A) data of 400kV Kansari Line-1 at Veloda was under recording

for the period 26.03.18 to 21.04.18. Therefore, Veloda end data was replaced with the

standby meter data at Kansari end.

c. 400kV Shujalpur line-1 at Nagda

The energy meter (NP-4229-A) of 400kV Shujalpur line-1 at Nagda, was under-recording for

the period 09.04.18 to 07.06.18. Therefore, Nagda end data was replaced with the standby

meter data at Shujalpur end.

d. 400kV GMR Warora line-1 at Bhadrawati

The energy meter (NP-2648-A) of 400kV GMR Warora line-1 at Bhadrawati was under-

recording for the period 26.04.18 to 25.05.18. Therefore, Bhadrawati end data was replaced

with the standby meter data at GMR Warora.

e. 400kV side of 400/220kV ICT-2 at ITARSI(PG)

The energy meter (NP-6222-A) data of 400kV side 400/220kV ICT-2 at ITARSI(PG) was

under-recording for the period 30.04.18 to 06.05.18. Therefore, 400kV side data was

replaced with the standby meter data at 220kV side of Itarsi ICT-2.

f. 400kV side of ICT-4 at Boisar(PG)

The date in the energy meter (NP-5511-A) of 400kV side 400/220kV ICT-4 at Boisar(PG)

was wrong for the period 04.05.18 to 21.05.18. Therefore, 400kV side data was replaced

with the standby meter data at 220kV side of Boisar ICT-4.

g. 400kV Bhadravati line-1 at Chandrapur

The energy meter (NP-2412-A) of 400kV Bhadravati line-1 at Chandrapur was under-

recording for the period 21.05.18 to 27.05.18. Therefore, Chandrapur end data was replaced

with the standby meter data at Bhadrawati end.

h. 220kV Korba line-3 at Budhipadar

The energy meter (NP-5944-A) of 400kV Korba line-3 at Budhipadar was under-recording

for the period 28.05.18 to 05.06.18. Therefore, Budhipadar end data was replaced with the

standby meter data at Korba end.

18.i. SEM Data discrepancy at Bhadrawti station

GMR Warora vide their email dated 17.07.18 informed that there was discrepancy in SEM

data (SEM Sr no-2648A) at PGCIL Bhadrawati end which has resulted into variations in

their weekly DSM settlement. Further they informed that from 46th time block of 26thApr’18,

there was sudden variation in the readings which continued till 46th block of 25thMay’18.

Total Line Loss has increased from 0.3% to 1.6% from 26th Apr’18 leading to loss in

injection quantum in DSM calculations.

GMR Warora have intimated to WRLDC vide mail dated 25th May’18. Followed by letter

dated 1st June’18 & reply letter on 29th June’18 (copy enclosed at Annex 18.i).

GMR Warora informed that they have dedicated 400KV D/C line of 33Kms length

connected to bhadrawati & considering generally adopted practice is penalizing us when

actual line losses are coming in the range of 0.16 to 0.30%. Since check meter are not

installed at PGCIL end, as per adopted procedure injection readings were computed based on

the notional loss of 2% by WRLDC.

GMR Warora have request CCM to kindly consider this as special case and evaluate the

readings as per actual line losses and accordingly modify the DSM bills of the said period.
