Sumy's Intellectual Meter Data Management System (SiMDMs)

High level Architecture of Sumy SiMDMs

Sumy designs the intellectual Meter Data Management System (SiMDMs) based on the requirements of Indian Utilities. This single, unified system consolidates metering data management business processes. Its comprehensive set of tools enables utilities to address traditional utility use cases, such as meter-to-cash billing data. Additionally, it also addresses emerging use cases that leverage register, interval, and time-of-use IoT device data to support a variety of mission-critical enterprise applications. In addition, SiMDMs offers an analytics environment based on state-of-the-art technologyand advanced analytics applications to leverage more value from the existing data.

SiMDMs is data repository aggregation and analytical tool.

Dashboard of SiMDMs can be customised as per the needs of Utility

Modules of SiMDMs:

  • Head End System to collect the Meter data at pre-defined intervals.
  • Data Repository
  • Calculations, Aggregations and Analytics.
    • Load forecasting
    • Load Control and Load Limitation
  • Remote Disconnection/ Reconnection
  • Reports:
    • Ad-Hoc or Self-Service Reports
    • Predefined reports
  • Event/Alarms
  • Load Management
  • SMDM Dashboard

SMDAs:

Sumy’s Meter Data Acquisition system (SMDAs) of SiMDMs facilitates the following meter parameters:

  • Load profile capture period
  • Demand integration period
  • Setting of parameters for time of day (TOD/TOU) billing
  • Prepaid function
  • Net metering
  • Billing date
  • Clock setting/time synchronization.
  • Load curtailment limit
  • Event setting for connect/disconnect
  • Number of auto reconnection attempt
  • Time interval between auto reconnection attempt
  • Lock out period for relay
  • Remote firmware upgrade
  • Password setting
  • Push schedule
  • Setting threshold limits for monitored parameters
  • Provision for adding more programming features in future

Reports:

Sumy has designed the standard reports as per the major utility’s requirement such as:

  • Daily data collection report
  • Usage exceptions
  • VEE validation failures
  • Missing interval Read date and times (on hourly, daily, weekly & monthly basis)
  • Physical meter events (install, remove, connect, disconnect) & meter reset report
  • Meter flags
  • Meter inventory
  • defective meters
  • AMI performance measurements
  • Threshold Exception
  • Any Customized report as per need

Events /Alarms:

SiMDMs can list the tampering events as per Zone, DT and individual meters.Following are the list of events along with date and time stamp that are supported by SiMDMs:

  • Terminal Cover
  • Case Open Detection
  • Natural Disturbance
  • Magnetic Interference
  • Injecting AC/DC High Frequency / Current Signal in Neutral
  • Under/Over Voltage and Over Current.

Analytics:

SiMDMs supports following Analytic reports by default, however more can be customised as per the Utilities Requirement.

  • Display consumption/load profiles by configurable period (15/30 min, hour, day, month, year etc.) day type (weekday, weekend, holiday, festival wise etc.) and by tariff, customer type, or any user specified collection of meters.
  • Generate peak and off-peak load patterns by aggregating all loads of DT/feeder/consumer group.
  • Performs DT/feeder wise energy audit. Performs load analysis for different groups and categories of consumers.
  • Has ability to provide the data to load forecasting, load research or demand response applications. Also performs error management like – missed reads and intermittent meter reads before taking into forecasting, load research or demand response.
  • Has ability to configure the system to effectively visualize consumption trends, identify unusual patterns and visualize load analysis to understand which assets are being over utilized.
  • Analyses data to identify new patterns of usage, setting fraud alert / transformer overload alerts / demand – supply gap alert, etc.
  • Has ability to receive and store outage and restoration event data from smart meters and outage systems and to log all such events for analysis.

SiMDMs to Head End System

There are two interfaces between SiMDMs to SMDAS /HES

Sumy Provides following SAP Services to Utilities:

  • On Demand & Event Data:

    • This is a bidirectional interface wherein event data is pushed by SMDAS / HES to SiMDMs and on-demand data like instantaneous meter reading is initiated by the SiMDMs. Connection and disconnection commands can be initiated by SiMDMs and furthermore processed using this interface.

  • Interval Data:
  • SAP AMI implementation.
  • SAP Training to utility users.
Interface between SiMDMs and CIS, Billing System , Analytics

SiMDMs to CIS, Billing System and Analytics Interfaces are bidirectional. Please refer below functional architecture:

Interface between Consumer Portal and SiMDMs

Following interfaces are required to integrate the Proposed SiMDMs system to Consumer Portal:

Consumer Portal to SiMDMs:

This will be bidirectional Interface:

  • To access the consumption, billing, payment, meter events, load profiles etc information.
  • To request the temporary connection / disconnection, load enhancement / change, address change etc.

SiMDMs to CIS / BILLING SYSTEM:

This will be bidirectional Interface:

  • To share the consumption, billing, payment, meter events, load profiles etc information to SiMDMs for consumer portal.
  • To process the request of temporary connection / disconnection, load enhancement / change, address change etc. to billing System.
Interface between SiMDMs and SMS / e-Mail

Purpose of this interface is to send the high priority alerts to notify the utility personnel to take an action on top priority.

Demand Response/Peak Load Management System

Sumy provides the demand response or Peak Load Management (PLM) Software with minimum follow-up reports after integration with SiMDMs and other legacy Systems.

  • Consumer category wise Time of Use (ToU) tariff on daily/weekly/monthly/ quarterly, etc., shall be made available on the consumer portal.
  • Daily load forecasting for the project area on hourly basis.
  • Import hourly drawl schedule (to be made available by the utility) for the project area.
  • Analysis of surplus/ deficit situation in daily drawl schedule.

a) Based on the above analysis design demand response (DR) and demand side management programs.
b) Command to be given to SiMDMs for reduction of drawl limit for identified group of consumers.
c) Notification for the modification in drawl limit to be sent to the consumers via SMS, email, etc., as well as made available on the consumer portal.
d) On completion of demand response event drawl limit of the above consumers to be restored.
