董箐水电站高尾水变幅水轮机选型设计

Type Selection for Turbine with High Tailwater Variation of Dongqing Hydropower Station

针对北盘江董箐水电站尾水位变幅大的特点进行水轮机选型设计,分析尾水位变幅大对水轮机特征参数选择及稳定性的影响,并提出合理的运行区域,为后续尾水位变幅较大水电站水轮机的选型设计提供了参考。

For the type selection of turbine with high tail-water variation of Dongqing Hydropower Station in Beipan River,the influences of high tail-water variation on steady running of turbine are analyzed and a reasonable operating range is put forward.The result can be as reference for following type selection of turbine with high tail-water variation.
