2.1.4 SEM : Technical Specification

The energy metering system is used for region, inter-regional energy metering for

bulk, inter-utility power exchanges. Static type composite meter is installed for each EHV

circuit, as a self-contained device for measurement of active energy (MWh) transmittals

in each successive 15-minutes time block and certain other functions, as described in the

following paragraphs.

Special energy meter of a uniform technical specification is provided on the electrical

periphery of each regional constituent to determine its actual net interchange with the

regional grid. Each interconnection shall have one (1) main meter. In addition one

check/standby has been provided such that the correct computation of net interchange of a

constituent is possible even when a main meter, a CT, or a VT has a problem.

The special energy meters is static type, composite meters installed circuit-wise,

as a self-contained device for measurement of active and reactive energy and certain

other parameters as described in following paragraphs. The meter is suitable to be

connected directly to voltage transformers (VTs) having rated secondary line-to- line

voltage of 110 V and to current transformer (CTs) having a rated secondary current of 1A

(model-A) or 5A (model-B). The reference frequency shall be 50 Hz.

The active energy (Wh) measurement is being carried out on 3-phase, 4 wire

principle, with an accuracy as per class 0.2 S of IEC-687/IEC-62053-22. In model-A,

energy is being computed directly in CT and VT secondary quantities and indicated in

Watt-hours. In model-B the energy display and recording is one fifth of Wh computed in

CT or VT secondary quantities.

Further the meter continuously integrate and display on demand the net

cumulative active energy sent out from the station bus bars up to that time. The

cumulative Wh reading at each midnight is stored in the meter's memory. The register

moves backward when active power flow back to station bus bars.



The three line-to-neutral voltages are continuously monitored, and in case any of

these voltages falls below 70%, the condition is suitably indicated and recorded. The

meters operate with the power drawn from the secondary circuits, without the need of any

auxiliary power supply.

The VAr and reactive energy measurement is also be on 3-phase, 4-wire principle,

with an accuracy as per class 2 of IEC-62053-23 or better. In Model-A, the VAr and

VArh computation is directly in CT or VT secondary quantities. In Model-B these are

displayed and recorded as one fifth of those in CT and VT secondary quantities.

There are two reactive energy registers, one for the period when average RMS

voltage is above 103% and the other for the period the voltage is below 97%.

The meters fully comply with the stipulations of IEC Publication 687 for 0.2S class

Static watt-hour meters, except those specifically modified here. The reference

ambient temperature is taken to be 30'C.

Errors are reasonable for all power factor angles from 0' to 360'.

The 15 min Wh have a +ve sign when there is a net Wh export from a substation bus

bars and –ve sign when there is a net Wh import. The integrating (cumulative)

registers for Wh and VArh move forward when there is Wh/VArh export from

substation bus bars and backward when there is an import.

The meters store all the above listed data in the memories for a period of 10 days. The

data older than 10 days get erased automatically. Each meter has an optical port on its

front for tapping all data stored in its memory using a hand held data collecting device.

The meters normally operate with the power drawn from the VT secondary circuits

without the need of any auxiliary power supply. Each meter have a built in calendar and

clock having an accuracy of 30 seconds per month or better.

Each meter has an electronic panel for display, on demand, the metered

information/data as specified by CTU.



Each meter has a non-volatile memory in which the followings are automatically

stored:

i) Average frequency for each successive 15-minute time block, as a two- digit code.

ii) Net Wh transmittal during each successive 15-minute time block.

iii) Cumulative Wh transmittal at each midnight.

iv) Cumulative VARH transmittal for voltage high condition, at each midnight.

v) Cumulative V.Arh transmittal for voltage low condition, at each midnight.

vi) Date and time blocks of failure of VT supply on any phase, as a star Mark.

The harmonics are filtered out while measuring Wh, VAR and VARH, and only

fundamental frequency quantities shall be measured/computed.

Each meter has an optical port on its front for tapping all data stored in its memory.

Portable or hand held data collection devices are used to serve as the interface

between the meters and the local personal computers (PC). The overall intention is to

tap the data stored in the meter's memories once a week, and transmit the same to a

remote central computer through a local PC. It is also possible to obtain a print out

(Hard copy) of all data collected from the meters, using the local PC.

2.1.6 Data storage

This 0.2 class accuracy static energy meter can record integrated average frequency and

active energy over every 15 min blocks. The SEM also stores the daily reactive energy

flows in low voltage & high voltage conditions. SEM can store data for 10 days. The text

file (*.NPC) made from coded files (*.MRI,*.DAT, *.DCD) etc includes data of one

complete day corresponding to the day on which reading is taken and 9 days of complete

data for the previous days.



2.2 Data Collecting Device (DCD)

It is basically data collecting device and used to transfer the tapped data from SEM to

PC. It has bi -communication with special energy meter along with personnel computer.

all these is done with communication cable one at DCD end and other at PC.





3.0 Metering Configuration

3.1 General

Meters have been installed so as to enable the measurement/computation of electrical

energy and other specified parameters. Additional 'check / standby' meters have been

provided at appropriate locations so as to facilitate the preparation of weekly regional

energy accounts in case any of the 'main' meters become unsuitable for the purpose.

3.2 Types of Meters

I) Interface Meter: Interface Meter is connected at the point of interconnection

with inter-state transmission system (ISTS) for the purpose of electricity accounting and

billing. Meter shall be owned by CTU.

II) Consumer Meter: Consumer meter means a meter used for accounting and

billing of electricity supplied to the consumer. Meter shall be owned by Licensee.

III) Energy Accounting Meter:Energy Accounting and Audit Meter means Meter

used for accounting of electricity to various segments of electrical system. Meter shall be

owned by generating company or Licensee.

3.3 Metering Arrangement

3.3.1 Metering arrangement for NTPC stations

Three sets of energy meter i.e. Main, Check and Stand-by energy meters are provided to

calculate the energy sent-out. One set each of Main & Check Meters is provided on all

outgoing feeders and stand-by meters are provided on the EHV side of the generator

transformer (GT) and station supply transformers

3.3.2 Metering arrangement for ICTs

For measurement of energy supply to a constituent/agency through an ICT, the Main

meter is provided on the HV side of the ICT and the Standby meter on the LV side of the

same ICT.



3.3.3 Metering arrangement for inter-State transmission lines.

In case of SEB-owned Inter-State transmission lines, say between State 'A' and State ‘B.',

the energy meters are provided at both the ends of the lines. The meter installed at end 'A'

is the Main meter for working out net drawal of SEB 'A' and that installed at other end 'B'

acts as check meter for SEB 'A', and vice-versa.

3.3.4 Metering arrangement for POWERGRID lines

On POWERGRID lines, unless an end is a regional energy accounting point, an Energy

Meter is provided only at one end of each line. The readings recorded by these meters are

being used for information and analysis only, and not for the energy accounting purposes.

3.4 Maintenance of Special Energy Meters

3.4.1 Testing and Calibration

All equipments are duly tested. In particular, each and every meter is being subjected to

acceptance tests as specified by CTU, at the manufacturer's works, before dispatch.

3.4.2 Periodic testing of accuracy

i) In-situ functional checking and rough testing of accuracy are being carried out for allmeters once a year by the CTU, with portable test equipment complying with IEC-60736,

for type and acceptance testing of energy meters of 1.0 class.

ii) Full testing for accuracy for every meter is being carried out by the CTU at an

accredited laboratory once every five (5) yrs.

The constituents/agencies may depute one authorized representative to witness the tests.

3.4.3 Meter Calibration

The meters normally need not to be recalibrated. However in case a meter is found to

violate any of its accuracy , functional requirements during the above periodic accuracy

checks, the same is replaced by CTU by a duly tested/certified meter, and the defective

meter is sent back to the manufacturer for appropriate recalibration and re-certification

3.6 PAIRS.DAT file

This file gives the LOC-ID of main meter and standby meter and the permitted

pair tolerance for each pair. Main meters are those which are connected on 400 kV side

of ICT or generator side of power station or sending end of inter state lines. The

standby/check meters are on the other end. Standby meters are connected in reverse

polarity so that sum of both MWh is zero in ideal condition. Suppose the power flow is

from main meter to standby meter, the main meter gives a +ve value and standby meter

gives a –ve value and vice versa. Tolerance value in MWh for a 15 min block in +ve

direction & -ve direction is given in this PAIRS.DAT, depending upon transformer /Line

loses & CT/PT errors.

The given tolerance value towards +ve side is called X value. The tolerance valuetowards –ve side is called Y value.

3.7 FICTITIOUS METERS

Sometimes it is required to treat a combination of METERS as a single entity. e.g.

(i) Total drawal of an SEB

(ii) Total relief from a generating station

(iii) Total transaction of energy between two regions.

In this case, these items can be treated as just like a single meter, we call it as

FICTITIOUS METER (FICTMTRS). The following listed meters are called

FICTMTRS used to simplify the calculation process. Every fictitious meter consists

and basically summation of certain no of Real meters. Real meters are the actualmeters which are placed at different location and store the raw data. E.g.

START

01 (FK-92) M9

+(FK-08) +(FK-09) +(FK-10) +(FK-11)

+(FK-12) +(FK-13) +(FK-17) +(FK-15) +(FK-16)

………………………..

100 (RN-97) M2

+(RN-95) -(RN-96)

101 (RN-99) M1

(RN-95)*3.8/100

END

------------------------------------------------------------------------------------------------------------

The detail list of FICTITIOUS METERS are given in ANNEXURE-B



4.0 Scheme for collection and dissemination of data

4.1 General

While CTU has the overall responsibility for supplying the meter data to ERLDC

on a weekly basis, the respective constituent’s agencies, in whose premises the energy

meters are installed, normally down-load the metered data from each of the meters on a

weekly basis or as and when requested by the ERLDC. The respective constituent’s

agency ensures that the data is down loaded in the specified time schedule. ERLDC, in

consultation with the constituents, prepares a scheme for the timely collection of the

metered data from each meter location and its further transmission to the ERLDC. The

constituent/agency shall also ensure the security of the metered data up to its delivery to

the ERLDC and seven days thereafter. All constituents shall provide the required

assistance/co-operation to ERLDC. Each station is also requested to keep back up of all

data systematically that are sent to ERLDC.

4.2 Data Collection from different location

At each metering locations data is to be collected from SEM once in a week. With

one data collecting device, data of about ten SEM can be collected sequentially and at

once dumped into PC. For dumping into PC the software given by supplier of SEM has to

be used. After downloading the metered data of seven days from each meter location, the

respective constituent’s agencies send the data normally through e-mail from specific

location to ERLDC. These data should reach ERLDC latest by Tuesday so that it doesn’t

cause any delay in processing. Special energy meters are either SECURE METERS

LIMITED (SML) or L&T Make. These raw metered data are non readable type (non

editable and naturally tamperproof). SML make meters have *.MRI or *.AMR file and

L&T make metres have *.DAT file. Since these files are non readable files, so these files

have to be converted to *.NPC file which is readable and editable. It is better to make

NPC file at RLDC to reduce human error.



4.3 Saving of Raw Data

Data after downloading attachments is saved in computer in a folder (e.g.

SEM_DATA). Since these data are in MRI or DAT file these files need conversion into

TEXT file (although some location sends NPC files along with both MRI and DAT files).But it is better to convert MRI and DAT file into NPC file at ERLDC to reduce human

error. After converting into NPC file these are stored in a folder called as ‘READINGS’.





5.0 PROCESSING & COMPUTATION OF DATA

5.1 Conversion into Text File/Software for Data Viewing

After receiving the data, MRI file and DAT file is converted into TEXT file called NPC.

This conversion is done with the help of respective software. MRI file is converted into

NPC with the software called SMARTGRID supplied by the Manufacturers and DAT file

is converted into NPC with the help of VINCOM software.

For Secure Meter: SMARTGRID

For L&T Meter: VINCOM

A) SECURE METER (SMARTGRID Software): All mri files are

transferred to SEM_DATA folder in C: drive before converting to text file(i.e

NPC file). Following are the steps to convert mri file into text file

.Step-I : Login the SMARTGRID software after click on SMARTGRID icon on desktop.

Step-II: Go to Data option on menu & click to Convert for conversion of mri file into

npc file.



Step-III: Select all mri file to be converted into text file



After conversion mri files along with npc files are transferred into respective location

wise folder in C:\READINGS\Mmyy\....

A) L&T METER (VINCOM Software): All *.DAT files are transferred

to SEM_DATA folder in C: drive before converting to text file (i.e NPC file).

Following are the steps to convert dat file into text file.

Step-I : Login the VINCOM software after click on VINCOM icon on desktop



Step-II: Click on Import from Data option on menu.

Step-III: Browse button to select the file and import one selected dat file at a time.



Step-IV: After importing convert into text file.



Step V: Finally conversion takes place. And click on ok and after each import and

conversion finally close the application software.

After conversion dat files along with npc files are transferred into respective location

wise folder in C:\READINGS\Mmyy\....

5.2 Viewing of npc file/structure of npc file

(i) There is one week heading for each meter data which gives the start date and end

date for which data is available e.g.

WEEK FROM 0000 HRS OF 12-10-07 TO 1230 HRS OF 22-10-07

(ii) For every day data there is a day heading that gives METER NO, three register

readings at 0000 HRS of the day, and date of the day e.g.

NP-4201-A 63895.0 97845.8 74358.6 12-10-07



Three cumulative registers are (i) WH register (ii) VAR register at high voltage (>103%)

(iii) VAR register at low voltage (<97%).

METER NO is of 9 characters, usually starting with NP (e.g. NP-0139-A). Character A

or B depending upon whether the meter is with 1 AMP CT or 5 Amp CT

(iii) One day data consists of 96 blocks. Each for 15 min is organised in 6 lines e.g.

WEEK FROM 0000 HRS OF 12-10-07 TO 1230 HRS OF 22-10-07

NP-4201-A 63895.0 97845.8 74358.6

00 14 +11.50 00 +11.10 08 +10.89 04 +10.34 01 +10

+10.56 00 +10.48 06 +10.20 11 +10.33 00 +10.05

+10.68 02 +10.66 12 +10.65 05 +11.01

………. …….. ……….. ………….. ………………….

Each line contains 16 blocks i.e. data for 4 hours. Time is followed by 16 blocks and

starting Time is in HOURS (2 digits) is given at the start of each line. Each block

contains a frequency code and WH for the 15 min. Freq code is of 2 digits and range is

from 00 to 99.

In between frequency code and WH there may be a “*” mark if there is any voltage

problem (V<70% during any instant in the 15 min). If any correction is done during the

15 min, there may be a “aa” or “rr” corresponding to advance or retard of the clock.

There may also be a case of voltage problem and time correction occurring in the same

15 min block.

At the end of 96 blocks the algebraic SUM of WH of all block is also given. One NPC

file may consist of data for one meter or more than one meter. Data for each meter startswith a week heading. After receiving the data from all locations for a week, they can be

combined to make a complete file for the week. A program APPEND.EXE is given for

that purpose.



5.3 Modification/Editing in Text file

After conversion into Text file (NPC file) every file is renamed as ddmm.NPC

where dd and mm correspond to the week for which data is being processed. Also extra

meter readings to be deleted from the text file which is not required and if somecorrection of date etc is required it is done in the text file and saved into corresponding

folder from where data have been received. These are normally saved in folder named as

“READINGS”.

5.4 Availability Checking

This is done to ensure whether data from all location has received or not. This is

checked by running software called REA2006 and we check for location from where data

has received or not received, if the data has not received, then the concerned agency or

person is contacted telephonically to send the data.

5.5 Methods used in case of Non availability of data

In case of non availability of data from any location, there are different alternative

methods to evaluate the data.

I. If Main meter reading is not available then check meter reading is used as

substitute for any particular location in FICTMTRS.CFG file.

II. Another alternative is to use other end data in case of non availability of data.

III. There is another approach to evaluate data by applying Kirchhof’s law at BUS

from where data is not available but this approach is not always valid..

Sometimes data are sent from different location by email attachment but required

proper data is not found in attachment. In that case the concerned agency or person is

asked to resend the data again.





(iv) Energy in MWH and MVARH is computed from WH and VARH using

corresponding CTR and PTRs. Wherever a pair is available (e.g. 400 KV and 220

kV side of ICT) computed energy is compared and data correction is done,

accordingly (for “*” marked blocks). Load curve can be plotted if required,

Drawal, share and overdrawal/underdrawal are computed using the FICTMTRS

(fictitious meters) concept.

(v) Output file can be made as desired by the user by making appropriate

configuration file.

(vi) Option is made available to change the freq code tolerance (temporarily) for

frequency analysis and to modify temporarily each pairs to get approximate pairs

tolerance value for analysis of each pair.

Following are the activities before creating data base.

First it is checked for the location from where data has not been received. If data is not

received from some location then it is asked to send the data. After receiving all the data

from each and every location, again all NPC file is combined together by

APPEND.EXE command and SREA file is created. After that it is gone through data

correctness stage. If status is not found ok then corresponding data file is edited that hascaused the error. Then Data base is created.

So finally by running REA2006 software we go through final processing with the

following steps.

I. Location of data not received

II. Data Correctness

III. Create Data base

IV. Compute ENERGY

V. Compute FICTMTRS

VI. MWH output





5.8 Discrepancies

If there is any discrepancy in the week’s data processing, it is listed out in register

for every week and these are used during final processing of data. These discrepancies

are forwarded to ERPC (Eastern Regional Power Committee) along with Raw andprocessed data. These discrepancies are also uploaded on ERLDC web along with ISGS

injection and Constituent’s drawl.

5.9 Data forwarding to ERPC

Processed data of the week along with raw data and discrepancies is forwarded to

Eastern regional Power committee (ERPC). Contents of the data which is forwarded to

ERPC are:

1) Raw data of each location

2) Constituent wise processed data

3) Processed MWH data

4) Day wise meter data

5) Configuration file of the week

6) Discrepancies, if any

7) Any other information, if required

6.8 Uploading of data on ERLDC web

Constituent wise net drawl and central sector Net generation along with region

loss and discrepancies if any, is uploaded on the ERLDC web site (http://www.erldc.org)

for the concerned week. Weekly UI calculations are being done by ERPC. As requested

by constituents, processed meter data as per calculations of ERLDC are being uploaded

just for the sake of gross comparison only.



6.9 Data Archives

A data archive for processed data along with raw data of every week is

maintained on PC to take care of any future dispute. Back up for Data Archive is also

maintained either on CD or Hard disc. The data archive structure is as follows:

Meter Archive
