Abstract: Due to the hydraulic characteristics of the runner, the hydraulic transition process of pumped storage power station is more complicated, and it also has a great impact on the safe operation of waterway system, which requires analysis. Based on the four-quadrant characteristic curve of the pump-turbine runner of a pumped storage power station with high head and long diversion pipes as well as the layout of the water diversion system, simulation and analysis on the hydraulic transition process of the water diversion system are carried out. The results show that the indexes of the hydraulic transition process can meet the control requirements which provides a reference for similar projects.

摘要: 由于水泵水轮机转轮特殊的水力特性,抽水蓄能电站水力过渡过程较复杂,对水道系统的安全运行影响较大,需要专门对其水力过渡过程进行分析。根据某高水头长压力管道抽水蓄能电站水泵水轮机的转轮四象限特性曲线及输水系统布置,对电站输水发电系统的水力过渡过程进行计算机仿真模拟和分析。结果表明,该抽水蓄能电站水力过渡过程中大波动的各项指标均满足控制要求,其研究思路可为类似工程提供参考。
