摘　　要：机组在实际运行中处于某些出力范围时会产生振动,这给厂内经济运行方法研究增加了难度。通过引入惩罚因子,对处于空蚀振动区的流量特性曲线进行变换处理,在此基础上应用动态规划方法得到水电站厂内最佳运行方式。并以三峡左岸电站为实例,制定了考虑空蚀振动区的最佳负荷分配方案。The units will vibrate in some output areas in actual operation.which makes a study of hydropower stations＇ economic operation methods more difficult.This paper transforms the flow characteristic curves in cavitation and vibration areas by leading in penalty factor and on this basis uses dynamic programming to get optimal operating conditions.This method is applied to the leftbank of Three Gorges Power Station,and the best load distribution is formulated by considering cavitation and vibration areas.
