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.
