某电站变顶高尾水洞水力工作特性模型试验研究

Research on hydraulic characteristics of tail tunnel with sloping ceiling for hydropower station by model test

通过水力学模型试验,研究一种新型尾水洞变顶高尾水洞在各种下游水位时的水力工作特性.试验结果表明,变顶高尾水洞能够取代尾水调压室,且保证调保参数满足规范要求.

The hydraulic characteristics of a new type tail tunnel with sloping ceiling for hydropower station is studied by hydraulic model test. The test results indicate that this kind of tail tunnel can replace a tail surge tank and makes the parameters of regulation guaranteed meet the standards′ demands.
