水轮发电机组甩负荷过渡过程的安全控制

Safe Control in Hydraulic Transients Caused by Turbo generator Load Shedding

对水轮发电机组甩负荷过渡过程运行工况、水压力变化值、转速变化值等进行了分析，对一般不低水头但引水系统较长水电站，提出用减压阀取代调压井的安全措施以及导水机构两段关闭规律的简化计算。

This paper analyses operating condition,pressure variety and turbine speed variety in transients caused by turbo generator load shedding. For water power station having long diversion system, middle and low water head, the safe measures of “replacing surge tank by pressure regulating valve”, and the simplified computation in turbine wicket gate 2 stage closing are presented in the paper.
