Generating Stations – ABT With the advent of the ABT regime, it is now mandatory for generating stations to monitor generation and supply on a continuous basis. ABT requires the generating station to comply with ABT regulations which in essence enforces commitment to deliver pre-agreed quantity and quality of power. Any defaults on quality or quantity are penalised under the ABT regime.CMS provides packaged generating station solutions comprising of 0.2s class accuracy meters from Elster along with an MDAS & ABT package to aid in implementing ABT in the generating station. The solution offered is comprehensive and covers all aspects in implementing ABT at a generating station like generation scheduling, energy auditing, meter data acquisition, online reporting of current generation (shortages / surplus), data and performance reporting, etc.

Key Features – CS-GEN-ABT

  • 0.2s class accuracy ABT meters
  • Meters comply to specifications released by CEA for ABT metering
  • In addition to meters having communication port, meters also have optical port for data reading by hand-held units.
  • Secure access: two levels of security provided (operator-level and administrator-level). Access control given to each operator based on functionality permitted for the operator. Other functionality not permitted are automatically not available to the operator.
  • Asset management: all details of meter and generator are configured – meter is associated with location ( with generator / feeder).
  • Scheduling: This provides an interface for the scheduled drawal and generation for each block on day-ahead basis – changes / modifications to the schedule are tracked. The final schedule can be mailed to SLDCs, etc. Schedules can be entered through the interface provided or through importing an excel file. Consolidation of schedule also carried out.
  • Online monitoring: Comprehensive online data from meters are displayed with live data of relevant parameters. Differences between scheduled and actual are displayed along with monetary implications. Live trending of parameters also provided. Current and previous block data are presented. Implications in terms of shortfalls / excesses are also flagged and shown on the interface.
  • Alarms: Certain alarm conditions can be defined and occurence of these conditions are visually depicted.
  • Reporting: Comprehensive reporting is provided – daily, weekly and monthly reports, UI reports, Band-wise UI reports, Incentive statement, Total export / import & plant load factor, etc. Any other reports can also be extracted from the database.

CMS provides ABT solutions to cater to the needs of the generating stations to implement ABT. The CS-GEN-ABT is a packaged solution comprising of :

ABT compliant meters (0.2s class accuracy ABT meters) are installed at various interface points from which consumption / feed data is required.The ABT meters capture all relevant ABT data and store the same in the meter.

The DCU interfaces with the meters and acquires data from the meters. The data is collated for quick, accurate and easy retrieval by the     MDAS server. The DCU is available in 4-port and 8-port versions – each port would connect to one meter or more meters.

The Meter Data Acquisition System (MDAS) server periodically polls the DCU to acquire all meters’ data. The acquired data is then     processed and stored in the respective database tables. Client HMIs then query the database for retrieving online data as well as generating reports. MS-SQL is used as     the database.

This application retrieves the data acquired from the various meters, carries out the required processing with respect to ABT and stores the processed data in      the database.

These are systems through which online data of the meters as well as reports can be viewed, generated and printed. Required ABT reports in terms of online     data as well historical would be generated. Client HMIs would have access to various parts of ABT data depending on User-level permissions. Live trending of online data     can also be seen on the Client HMIs.

 The following diagram illustrates the architecture of the system:
