摘　　要：通过特性曲线交点的方法对发电机组循环水系统进行计算分析,在此基础上分析了动叶开度可调式循环水泵运行方式对凝汽器端差和真空度的影响,并用试验数据进行了模型验证。最后运用基于最佳真空的优化准则对机组循环水系统进行了优化,提出了优化方案,可有效降低发电成本。The circulating water system was calculated and analyzed by the method of intersection of characteristic curve. On this basis,the effect of the adjustable pump running mode on the end difference and vacuum degree of the condenser was analyzed,and the model was validated by the test data. Finally,the optimization criterion based on the best vacuum was conducted,and the optimization scheme of the circulating water system was put forward,which could effectively reduce the power generation cost.
