Feeder Energy Audit through CMS Software

Feeder EA through CMS:- why??

MERC Order :- MERC ,in their order on 27.04.2007 ,has directed MSEDCL to carry out Feeder wise Energy Accounting with consumer database and submit the Feeder wise information by the end of Oct-2007.Further it is stated that the commission intends to move towards Feeder wise approachfor Energy Accounting and Load Shedding purpose MERC Order

Feeder Energy Audit is already performed in FEMS software. However FEMS limitations are :- 1. Consumer Database is not available.

2. Billed consumption information DTC wise. 3. No provision to accept Feeder Meter Readings

Feeder EA through CMS:- why??

CMS system already has consumer level database.CMS has DTC energy Audit logic already available.CMS system already developed in house and easy to modify.Additionally DTC – consumer Level mapping already available in CMS.

Benefits:- 1. Consumer Level database is available 2. DTC database is available 3. Provision for accepting Feeder Readings / Feeder Photos 4. No need of maintenance of two system for Energy Audit works

Prerequisite for Feeder EA through CMS• CMS system Must have following tables :-

-- BILL_INFO-- BILL_INFO_HISTORY-- HT_DATA (HT consumer / LTIP consumption)-- FEMS_LNHTFEED ( From FEMS system) This table

has already the HT consumer / Feeder Mapping. -- FEMS_Archht ( From FEMS system) This table has

month wise HT consumption available ( for old data)-- FEMS_MSTDTC ( From FEMS system) This table has

already the DTC / Feeder Mapping -- FEEDER_INPUT_DETAILS : - Feeder Inputs received

from Field staff / Hourly data /Feeder Meter readings-- BULT

Tables in Feeder EA

• FEEDER_DTC_CONSUMER - stores consumer level information of Billed consumption • FEEDER_DTC_CONSUMPTION - DTC level grouping of Billed consumption • FEEDER_INPUT_DETAILS - Feeder wise input details• FEEDER_METER_MASTER - Feeder meter details

• FEEDER_METER_READINGS – Monthly Feeder meter readings

• AG_METERED_INDEX - computes Bu wise month wise metered AG index• SSFDR_detail – stores the hourly consumption from hourly system• Ssfdr_master – stores the feeder master information• FEMS_LNHTFeed – mapping of HT consumer to Feeder from FEMS system• FEMS_ARCHHT – Stores HT consumption for old period• FEMS_MSTDTC – Mapping of Feeder and DTC • HT Data :- CMS table storing HT consumption and LTIP consumers• RPT_FMS:- Stores Feeder wise month wise EA details

Procedures in Feeder EA

• FEEDER_DTC_CONSUMER_PROC:

This procedure extracts consumer wise information from the tables Bill_info & Bill_info_history

tables and inserts into FEEDER_DTC_CONSUMER table.• FEEDER_DTC_CONSUMPTION_PROC:

This procedure extracts DTC wise information from the table FEEDER_DTC_CONSUMER

And stores it into FEEDER_DTC_CONSUMPTION table.

• FEEDER_DTC_HT_PROC: -

This procedure extracts DTC wise information from the tables HT_DATA and

stores it into FEEDER_DTC_CONSUMPTION table for LT IP consumers.

In second part HT consumers data is extracted and stored in FEMS_HT Consumers table.

• FEMS_HT_CONS_PROC:-

This procedure extracts DTC wise information from the tables FEMS_ARCHHT and

stores it into FEEDER_DTC_CONSUMPTION table if FEMS data is available. (provision for old HT data).

• AG_METERED_INDEX_PROC:- This procedure computes bill_month, BU wise AG Load_index and stores into AG_METERED_INDEX table.

Procedures in Feeder EA

• AG_UNMETERED_PROC:

This procedure computes consumption for the unmetered AG consumers from metered AG Index and stores it into FEEDER_DTC_CONSUMPTION table.

• RPT_FMS_PROC:

This procedure computes the feeder wise information for all the consumers and stores it into RPT_FMS table.

• UPDATE_RPT_FMS:

This procedure computes feeder wise ht_billed_consumption, billed_consumption & LT loss

and updates it into RPT_FMS table.
