水电站引水系统取消尾水调压室过渡过程计算研究

Computation Research of the Transition Process of the Diversion System at Hydropower Station

对洪家渡水电站引水系统在设置尾水调压室和取消尾水调压室两种情况下的过渡过程进行了计算研究 .计算表明 ,通过考虑机组特性、优化机组导叶关闭规律及合理整定调速器参数 ,该水电站取消尾水调压室的方案是可行的 ,其各设计参数控制值基本上能满足设计要求 .

This paper presents the main results of the research on the transition process of the diversion system at the Hongjiadu hydropower station in the presence or absence of the tailwater surge chamber. The results show that it is feasible to remove the tailwater surge chamber at the station in consideration of the optimized closing of the guide blades and the properties of the units. The governing values of parameters can basically satisfy the requirement for design. The present achievements have been used as one of the important bases for comparision of alternatives of the station.
