Abstract

Variable-speed fans are employed to support cold source for direct air-cooled units, and their speed regulation can ensure continuous control of condenser pressure and turbine power. The condenser pressure closed-loop control system is, on the basis of safe regulation, designed to ensure the unit changing its load with a rapid speed when it is in a load-change condition. The dynamic model of fan speed to condenser pressure is set up by identification method and a novel load-change strategy based on the condenser pressure regulation is proposed. The simulation on a 300MW unit has proved it improves the load-change capability significantly.
