河口村水电站水轮机选型设计

Type Selection of Hydraulic Turbine for Hekoucun Hydropower Station

河口村水电站设置大电站和小电站,两个电站的运行水头范围、机组安装高程、机组布置型式等均不同。根据电站的布置特点和运行水头范围,通过模型参数比较分析,确定了水轮机机型及主要参数;结合经济和技术性能、运行灵活性等因素,合理选择了机组台数和机组装置型式。

There are two hydropower stations in Hekoucun hydropower project. The operation range of water head,setting elevation,unit layout of these two stations are different. According to the characteristics of layout and water head,through comprehensive comparisons and analysis of model parameter,the turbine type and main parameter were determined;combining with the factors of performance of economy and technology,operation flexible and etc. ,the number and type of units were selected rationally,which guaranteed the station operation steady and safety.
