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. 1

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 . 1

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. 1

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 1
11
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. 1

RPS Application Architecture
IEE Monthly Consumption Baseline Model Deviations Actual / Predicted Consumptions Other Estimation Models Average Demand Tamper Counts Coincident Tamper Flags Service Orders Investigation Information RPS Data Mart - Readings Data - Interval Data - SIC/NAICS - Tamper Events - Service Orders - User Defined Attributes - Account Status - Meter Status - Daily Consumption - Occupancy Change - Meter Change-out AMI, AMR Data Collection Systems Daily feed Weather Data Utility In-House Data All of external info (three buckets to the left) feed into the IEE platform and are extracted daily to the RPS Data Mart, from which all of the RPS calculations and analyses are run. As part of the overnight batch process in the RPS datamart, we run analytics which calculate an estimated consumption for each account based on weather data and individual consumption history. Besides this estimated consumption many other useful metrics are calculated as you will be able to see during the demo. You will see in the demo that there are many other important The most powerful part of the RPS is the application is the RPS functionality which allows the RI to apply wide range of filters and thresholds for just about any data element in the RPS datamart. Once a final suspect list is created it can be exported for further analysis or an investigation can be initiated. Once an investigation has started and as part of the investigation the status changes for instance from “Assigned to the field” to “Tamper found” then this new status can be uploaded to RPS and this additional information gets linked to the specific account. In this way the RI can track the status of actions taken on each suspect account. Suspect List RPS Application Initiate Investigation 26

Usage Score How Baseline Consumption is Calculated
Each account is evaluated differently depending on its own consumption patterns over several months. The mean is different for each customer. In this scenario, a consistent traveler standard deviation is much broader than the homebody’s. Note that the baseline model calculates when someone is outside their standard usages, and this is calculated uniquely for each account. Traveler’s Billed Consumption Traveler’s Standard Deviation: 17.54 Homebody’s Standard Deviation: 4.62 Homebody’s Billed Consumption
28
Detailed View The RPS Data mart stores only monthly consumption data. IEE stores all the data. RPS can calculate weekly and daily consumption values on-the-fly. These values can be calculated for the drill down. Daily and Weekly Consumption for Interval and Daily Register Reads End of Month consumption for Monthly Register Reads Weekly Daily If the data was collected from an interval channel the customer can drill down and look at the data on a weekly or daily resolution levels. Normally this step is only taken ones an account is considered suspect. 28
29
Suspect Account Consumption dropped and tamper flags occur. No explanation for this behavior Suspect account . Consumption drop co-insides with tamper flags. No Service order, occupancy change, account or meter status or any other of the available information can explain the tamper flags or the consumption drop. This is a suspect account and should be investigated in the field. 29

Asset Management – Better Data Means Better Results
How do actual rather than estimated loads affect distribution asset analysis and design? How do automated design tools impact design quality and enforcement of engineering standards? Are my transformers over-loaded? Under-loaded? Can I reduce O&M expense and / or capital expenditures? Distribution Asset Analysis & Design Distribution Asset Monitoring & Control Can I use the AMI infrastructure to monitor distribution circuits and automate distribution operations? What are my distribution circuit loads Can I remotely monitor and control capacitor banks? Can I monitor power quality? Asset Management Portal Sample Asset management using IEE Provide simple Transformer Load Management overloaded tx calculations Aggregate usage to transformer Compare against transformer name plate rating Calculate overload % Provide list, sorted by % overloaded, color coded

Future is in modularity
2 “Plug & Play” Field Swappable Modules (FSM) Extended options for communication to the host (LAN/WAN): GPRS, 3G, Ethernet, PLC, Mesh RF etc... Wireless communication in the home (HAN): Zigbee, Mbus Wireless, RF433MHz etc... Modularity is key to ensuring that the utility will not be tied down to one specific communication type Itron’s new metering and communication platform is designed on a modular architecture, accommodating not one but two external, field swappable modules affording various communication technologies (PLC, GPRS, UMTS/3G, Ethernet, Mesh RF, Zigbee, MBus wireless, etc.). This translates into easy adaptability of communications to both the local area network (LAN) and the home area network (HAN), as requirements and technologies evolve. Remarks: The FSM2, for the HAN Can support two interfaces simultaneously (e.g. ZigBee + M-Bus) Optional fixed communication port: Mbus wire
54
FSM 1: communication to the head end system
GPRS, 3G, Ethernet, … First version/release of the meter platform will cover PLC SFSK, GPRS, 3G UMTS & Ethernet The next releases will be PLC OFDM PRIME or Mesh RF depending on market opportunity PLC OFDM PRIME vs PRIME G3: what is the best? => no specific advice. We are involved in both alliances. Once we have return from experience (PRIME Meter from itron Q3 2012, Linky G3 pilot expected in 2012), we will be in better position to compare. => We will integrate whatever market is requiring (provision has been made to be able to manage both) IPV6 with PLC OFDM G3 IPV6 ready with 3G/UMTS (network operator dependant) Mesh RF: - already expertise from the US (Openway Cisco IPV6) - also other technology under evalution - selection under discussion - mainly depend on customer requirement - no new meter development, just FSM development needed - will be based on open standard Remark: of course Data concentrator, or gateway, will be part of end to end offering. Supporting any communication media choosen, or protocol PLC S-FSK G1 PLC OFDM PRIME PLC OFDM G3 Mesh RF
55
FSM 2: COMMUNICATION IN THE HOME
