【摘要】 大流量、中低水头水电站引水发电系统的水力过渡过程及水工模型试验研究是一个新课题。结合泸定水电站引水系统布置及调压室方案选择,进行了模型试验研究。根据水电站引水系统非恒定流模型相似率,导出了模型各物理量之间的比尺关系,对调压室方案进行比选,论证了泸定水电站引水系统布置形式的合理性。为工程设计提供了依据。更多还原

【Abstract】 The study on transient process and the hydraulic model test of headrace-generation system of hydropower stations with large discharge and low-to-medium head is a new topic in recent years.For determining the layout of headrace system and the type of surge chamber of Luding Hydropower Station,the hydraulic model tests are conducted for the headrace-generation system.Based on the similarity law of unsteady flow in pressure diversion systems,the similarity conditions for the hydraulic model and the prototype are derived.The surge chamber designs are compared by the tests,and the tests also demonstrate that the layout of headrace-generation system is reasonable.These tests provide a basis for engineering design.更多还原
