ABT(Availability based Teriff) System
ABT Software is package for power plant including Energy meters, hardware and software required to monitor ABT tariff plan for power plants. This software provides target about generation set points to make maximum profit based on current grid situation and plant power running cost. Software handles various inputs directly from Energy meters, can handle multiple fuels for power plant and provides various reports.
Needs of ABT Regime
- ABT made our conventional monitoring systems obsolete.
- Increasing emphasis on commercial aspects of plant operation.
- Need to respond to needs of Operation Engineers in block-to-block decision making.
- Running average frequency of a block
- Running average ex-bus energy sent for a block
- Asking rate / Target Generation based on cut-off frequency
- Net Gain
- Declaration based on trending.
Provide the Solutions for :
- Need for more Accuracy of metering
- Bifurcation of Gas/Liquid
- Cut-off frequencies on Gas/Liquid
- Scalability
- Configurability
- Time Synchronization with GPS
- Ambient temperature acquisition
- Dynamic changes in MIS reports
- Connectivity with various meters on heterogeneous networks.
Features of ABT-RTMST
- Displays all ABT parameters in real-time in Control Room.
- Immensely useful to Desk Engineers in making commercial judgment in real-time operation.
- Displays “Ex-bus generationâ€, “Net gain†and break-up of generation on Gas / Liquid fuels.
- These inputs were earlier not available to Desk Engineers at Kawas.
- Generates audio / visual alarms. E.g. when
- Ex-bus Generation > DC
- Grid frequency > Cut-off Frequency
- Accuracy of 0.5% in MW (Based on meter accuracy)
- Expandable: Can be accessed from any PC on LAN.
- Low cost:
- Cost of similar system is more than Rs. 45 to 50 lakhs approx.
- Utilizes existing energy meters impulses
- Generates daily MIS report on Station performance under ABT regime
