摘　　要：三峡电站具有不同于其它水电站的动能特性，其特殊性表现在高、低两段水头是获得电量的主要水头区间，同时也存在着各自的特殊问题，即高水头、部分开度的稳定性；低水头、大开度的泥沙磨损。这一特殊性将对三峡机组参数选择及水轮机水力设计产生重大影响。The Three Gorges Hydropower Station is of the kinetic energy characteristics not the same asother hydropower stations. Its specific characteristics show that the two sections of low and high water headsis the main interval to generate electric energy. However these two heads have their own specific problemsrespectively, i. e. low stability as part opening under high water heads, while serious wear due to moresediments as full opening under low water heads. Such a specific characteristic greatly affects the parameterselection and the hydraulic design of generating sets of turbines for the Three Gorges.
