文摘Systematical analysis on factors affecting the cold end system in power plants was conducted.The optimization model was obtained,which regarded the minimum net coal consumption rate as the objectivefunction,used several objective conditions as the variables,such as flow rate and temperature of the circu-lating water,supercooling degree of the condenser,fouling and air leakage in the condenser.Genetic algo-rithm was employed to optimize the multiple factors affecting the cold end system,and the optimizationconditions for the minimum net coal consumption rate and the corresponding parameters were obtained.Comparison indicated that this genetic algorithm not only can optimize the cold end system quickly and ac-curately,but also can compensate the economic efficiency drop that caused by defects of some parametersthrough automatic adjustment of the parameters.
