AI Technical Summary

Technical Problem

During load changes, the differences in operating characteristics between the boiler and turbine equipment in supercritical carbon dioxide coal-fired power generation units make coordination difficult. Existing control systems cannot efficiently coordinate the boiler, compressor, and turbine equipment, affecting the unit's peak shaving and load change capabilities.

Method used

A load management and operation control system for a supercritical carbon dioxide coal-fired power generation unit was designed, including an instruction formation and decomposition system, a control loop system, and an actuator system. The system dynamically compensates for the power instruction on the turbine side by using the pressure deviation signal on the boiler side, intelligently decomposes the grid instruction into independent master control instructions for the boiler, turbine, and compressor, and achieves precise control of the equipment through the control loop system and the actuator system.

Benefits of technology

It has achieved deep peak shaving and rapid load change capabilities for supercritical carbon dioxide coal-fired power generating units, reduced interference between equipment and frequent adjustment losses, and improved the stability and economy of the units.
