对常用二种类型调压室引水系统的非恒定流进行计算，同时得出了每种类型指定断面的压力；水轮发电机组的转速变化；调压室水位波动过程，最后进行了定性分析比较。 The unsteady flow of the two types of surge chamber water diversion system is calculated and the pressure of the designated section of each type is obtained. The rotational speed variation of the hydrogenerator unit and the fluctuation process of the water level in the surge chamber are finally analyzed and compared qualitatively .
