Important design consideration

• Meters installed for Industrial & commercial consumers are of different makes. It was decided not to replace existing meters for the purpose of AMR.

• The meters are read using API provided by meter manufactures as per MIOS standards.

• The modems installed for AMR are designed to have bidirectional communication and remote configuration features and work on GPRS technology.

• To manage large amount of meter data ,a Meter Data Management System (MDM) is installed. The MDM system generates many MIS reports which help in faster detection of metering abnormalities /theft /tamper etc .

MDAS

Meter Data Acquisition System (MDAS) :

• • A common Meter Data Acquisition System is deployed to read all makes of meters. MDA system acquires meter raw data stored in the Modem memory. • Raw files received from different types of meters are processed through the respective API utility tools and converted into XML file.

• A Web Interface is provided for the MDA system. A client can access instantaneous data collected from meter at 15 minute intervals. • Also, health status of all the installed modems, communication logs and events can be seen on the web portal.

AMR equipment - MDMS

Meter Data Management System (MDMS) :

• Itron Enterprise Edition (IEE) is used as Meter Data Management (MDM) System.

• MDM is the central repository for meter data and maintains interval data, event logs , register data & outage history for all the connected meters.

• The MDM system has a facility to upload meter data read through CMRI. This facility is used to manage the data of meters not covered under AMR.

• MDM validates meter data as per predefined validation rules to ensure that only correct data is sent for billing.

• The MDM system provides many useful MIS reports

Middleware

Middleware :

• The SAP PI middleware is used for integrating MDAS, MDM and SAP billing system for seamless exchange of data.

• The SAP PI system maps the meter CDF file with MDM system. • New meter creation or deletion is done in SAP system which is communicated to the MDM through the middleware.

RPS Focuses on Commercial Losses

Administrative Loss Commercial Loss Technical Loss Profitability Taxes Financial Costs Energy Purchased Depreciation O&M Theft from known accounts: Commercial Losses

Theft Mis-metered Un-metered / Unbilled Purposeful diversion of consumption to avoid accurate Billing by customers known to the utility, which includes:    Unauthorized consumption Self-reconnect Stopped meters

IEE Revenue Protection

Analytics application that helps utility Revenue Assurance teams identify tamper and theft

 Correlates tamper events, field work orders, weather data, and customer usage to identify suspects  Includes workflow to trigger field work and track investigation status  Includes robust statistical model to compute customer baseline usage levels

The expected benefits of RPS are:

 Quicker investigation and recovery of abnormal metering cases  Increases revenue recovery for unbilled electricity.

 Improves operational efficiency of revenue investigation / Vigilance teams.

 Reduces dependence on field staff to visually inspect meters.
