When upstream and downstream water regime changed in long-distance pressurized water delivery pipeline of cascade pump stations, it is easy to cause the change of water pressure in pipeline and hydraulic parameters such as flow velocity, and results in water hammer. In order to meet the water delivery requirements of the pipeline and ensure its safe operation under various working conditions, one-dimensional characteristics method and 3D VOF coupled methods were used to simulate. The mathematical model for transient process analysis of long-distance water delivery system of cascade pump stations was established to analyze the change and law of pipeline internal pressure and water level in outlet pool during long-distance water delivery system in Chuhe Level Ⅳ station of Simashan River Diversion Project under working conditions, such as suspending period and power losing period. It also shows that the safety of the entire pipeline system can be better guaranteed though the reasonable open-close laws of the terminal gate and side gate.

梯级泵站长距离有压输水管道上下游水情发生变化,易导致管道内水压、流速等水力参数变化,进而引起水锤。为满足管道的输水要求,保障其在各工况下安全运行,采用一维特征线法和三维VOF相耦合的方法对其进行数值模拟,建立梯级泵站长距离输水系统过渡过程分析的数学模型。分析了驷马山引江工程的滁河四级站长距离输水系统在泵站停机、失电等工况条件下管道内压力、出水池水位的变化规律,得出通过末闸和侧闸的合理启闭可以更好地保障整个管道系统的安全。

梯级泵站长距离有压输水管道上下游水情发生变化,易导致管道内水压、流速等水力参数变化,进而引起水锤。为满足管道的输水要求,保障其在各工况下安全运行,采用一维特征线法和三维VOF相耦合的方法对其进行数值模拟,建立梯级泵站长距离输水系统过渡过程分析的数学模型。分析了驷马山引江工程的滁河四级站长距离输水系统在泵站停机、失电等工况条件下管道内压力、出水池水位的变化规律,得出通过末闸和侧闸的合理启闭可以更好地保障整个管道系统的安全。

When upstream and downstream water regime changed in long-distance pressurized water delivery pipeline of cascade pump stations, it is easy to cause the change of water pressure in pipeline and hydraulic parameters such as flow velocity, and results in water hammer. In order to meet the water delivery requirements of the pipeline and ensure its safe operation under various working conditions, one-dimensional characteristics method and 3D VOF coupled methods were used to simulate. The mathematical model for transient process analysis of long-distance water delivery system of cascade pump stations was established to analyze the change and law of pipeline internal pressure and water level in outlet pool during long-distance water delivery system in Chuhe Level Ⅳ station of Simashan River Diversion Project under working conditions, such as suspending period and power losing period. It also shows that the safety of the entire pipeline system can be better guaranteed though the reasonable open-close laws of the terminal gate and side gate.
