1 …Message Box ( Arial, Font size 18 Bold) ` Presentation Title ( Arial, Font size 28 ) Date, Venue, etc..( Arial, Font size 18 ) AMI experience of Tata Power

2 …Message Box ( Arial, Font size 18 Bold) Introduction Tata Power is engaged in Supply of Electricity across Mumbai Licensed area. The total spread of licensed area is 485 sq. km. and houses a population of approximately 1.45 crores Customer base in the Mumbai licensed area is around three lakh. Tata Power has recently installed an Automatic Meter Reading system for high value customers in Industrial & commercial segment.

3 …Message Box ( Arial, Font size 18 Bold) Objective of AMR system To fully automate the process of meter reading and billing without any human intervention. Faster detection of metering abnormalities, theft and network faults. Monitoring and profiling energy consumption of consumers. Provide load profile data to key customers on Tata Power Customer Portal. Facilitate accurate Load forecasting. Facilitate Demand Response Initiatives.

5 …Message Box ( Arial, Font size 18 Bold) 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. Also, health status of all the installed modems, communication logs and events are captured in MDAS.

6 …Message Box ( Arial, Font size 18 Bold) MDMS Meter Data Management System (MDMS) : 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

7 …Message Box ( Arial, Font size 18 Bold) MDMS The MDM system has following functional elements - Data collection, aggregation and analysis - Validation, Editing & Estimation - Report generation and status reporting - Event list - Customer Care Itron Enterprise Edition Platform Meter Data Management Customer Care Curtailment Manager Revenue Protection Suite Multiple Data Collection Systems Handheld AMR Solutions C&I Meter and Collection Systems AMI Utility Operational and Back-office Systems

8 …Message Box ( Arial, Font size 18 Bold) 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.

9 …Message Box ( Arial, Font size 18 Bold) Communication -Last mile connectivity & related issues Selection of communication technology < Speed < Reliability < Data Security < Cost ( Capex + Opex ) GPRS was selected as the best option on the above parameters for high value commercial and industrial consumers. Meter protocols Intelligent Modems are deployed which collect meter data using API API are provided by Meter suppliers as per MIOS. Modems collect data from meter at 30 minute interval & stores the same in its memory. The data is pushed every midnight to MDAS.

15 …Message Box ( Arial, Font size 18 Bold) Last mile connectivity in AMR The capital & operational cost per meter is relatively high for GPRS. Hence, GPRS is not viable for low end consumers. It is necessary to explore technological option suitable for deployment of AMR for low end consumers. In many Residential / Commercial complexes, large number of meters are installed in close vicinity and form a cluster. RS-485 Modbus seems attractive and viable option for covering cluster meters under AMR.TPC has installed one pilot based on RS-485 technology and the performance is under observation. Physical looping of meter communication ports is cumbersome and tamper prone. RF Mesh seems to be an option. TPC is planning to set up a pilot based on RF Mesh technology for cluster metering installations. For Residential consumers, PLC may be a viable option. TPC is planning to set up a pilot project to explore this option.

17 …Message Box ( Arial, Font size 18 Bold) Pilot project on RS-485 Around 40 number three phase WC meters installed in a commercial complex are covered under pilot. All meters are L & T make with inbuilt RS-485 port The RS-485 terminals of all meters are connected in a daisy chain and are looped to a data concentrator. The data concentrator collects meter data once every fifteen minutes and stores the same in its memory. The data concentrator has inbuilt GPRS Modem which pushes meter data to Head end system at scheduled interval( Once a day)

22 …Message Box ( Arial, Font size 18 Bold) Pilot with RF Mesh technology A pilot project based on RF Mesh technology is planned to be set up covering about 200 meters. The meter data will be collected in a data concentrator using RF. The DCU will push the data to Head end system using GPRS. The proposed system architecture is as below 22

24 …Message Box ( Arial, Font size 18 Bold) Pilot with PLC technology A pilot project based on PLC technology is planned to be set up covering about 100 meters in residential segment. The meter data will be collected in a data concentrator using power line as a communication media. The DCU will push the data to Head end system using GPRS. The proposed system architecture is as below

27 …Message Box ( Arial, Font size 18 Bold) Pilot on Smart Metering solution It is proposed to install one pilot towards implementation of Smart Grid initiatives. This would include smart metering & Home area network. Smart metering will include < Remote disconnection /reconnection < Load control / Device control Home Area Network (HAN) with energy gateway < Demand Response Signaling. < Provision of Customer Energy Usage Information to In-Home Displays. < Control Activation/Deactivation of HAN Appliances. < Real time pricing signals
