Abstract
The operation state of cold end system of thermal power units directly affects the safety and economy of unit operation.A typical cold end system with a closed cycle water system was taken as the research objective,and optimization scheduling models for circulating water pumps,low pressure cylinder exhaust models,condenser performance calculation models,cooling tower performance calculation models as well as performance calculation models for each subsystem of the cold end system were established.The operation of the above models was studied,and the optimal economic operation of the cold end system was achieved.Taking the cold end system of a 1 000 MW ultra-supercritical thermal power unit as the research objective,the optimal operation model of the unit's circulating water system under different loads and ambient temperatures was studied based on the cold end optimization model,and the effectiveness of the method was verified.The research results can provide reference for the scheduling of circulating water pumps in cold end systems.关键词
