摘　　要：通过对不同循环水温度下,循环水泵运行方式变化带来的耗功变化及对应300MW下由于低压缸排汽压力变化造成机组微增出力变化的定量分析,找到最优的排汽压力和循环水流量。对于实际运行中循环水泵运行方式的确定提供了理论支持,为火电机组商业运行的经济性分析提供依据。但在实际运行中,由于凝汽器运行工况较复杂,可根据排汽压力的变化对机组功率的修正,找到实际经济工况。Through quantitative analysis of power comsumption change caused by circulation water pump operation mode change and units little increasing output change caused by low pressure cylinder exhaust pressure change on the condition of below 300 MW,it finds the optimal exhaust pressure and circulation water flow rate.it provides theory support to determine circulation water pump operation way and it also provides basis for economy analysis of thermal power units commercial operation.But in the actual operation,Because condensor operating condition is complex,we can find actual economic operating condition according to exhaust pressure change to readjust units power.
