摘　　要：循环水系统最优化运行方式 ,主要是依靠计算机确定循环水泵最佳运行台数和每台泵的最佳循环水量 ,以获得机组运行最佳经济性。以单台机组多台可调节叶片角度的循环水泵组为例 ,建立动态规划模型 ,给出合适的计算过程 ,从而得到最佳的泵组合及最佳循环水量。运行人员可根据计算机运算的结果进行调整 。By means of computer,the most optimized operating mode of a circulating water system confirms mainly the running pump number and the most optimized circular flux,and achieves the best operation economy.For the example of one unit and many circulating water pumps with adjustable vane,dynamic classified model was established.By using appropriate calculating process,the most optimized running pump number and circular flux would be found.According to the results,operators can adjust the operating mode that can lay the foundation for energy saving and cost decreasing.
