Intelligent Heat Load Dispatch for Multiple CHP Units
Processing plant operating data and optimizing heat load allocation across two 330 MW and two 660 MW CHP units over a wide operating range.
- Measurement points
- 300+
- Coal consumption reduction
- 1.2 g/kWh
- Plant configuration
- 2 × 330 + 2 × 660 MW
Background
The plant comprises two 330 MW units and two 660 MW units. Heat load allocation must simultaneously satisfy heating demand, power generation schedules, and equipment operating limits.
Methods
- Cleaned and synchronized operating data from more than 300 measurement points, standardizing timestamps and interface fields.
- Translated heating demand, power generation schedules, and unit output limits into heat load allocation constraints.
- Calculated the allocation across four units for each operating condition and validated the results against historical plant data.
Results
- The average net coal consumption rate during the heating season decreased by 1.2 g/kWh.
- The system calculates heat load allocation in real time and delivers the results to plant operators as decision support.
