水电站水头

河床式水电站水头比较低，而单机流量通常较大，这样水电站厂房的进水口、蜗壳和尾水管等尺寸较大。

In general , the head pressure of power station in river channel is lower comparatively , but the unit discharge is always greater , in this way , the dimension of the hydropower house is usually larger .

作者根据设计实践将水电站的水头（Ht）与出力（Nt）的关系归纳为三种情况：①同步；②异步；

Based on his own design practice , the author sums up three cases between head and output at hydropower stations : ① Synchronous , ② asynchronous , ③ partially synchronous or asynchronous .
