摘　　要：随着我国对水电资源开发水平不断提高,水电站渐渐向高水头大容量的冲击式水轮发电机组过渡。以往子沟水电站为例,研究冲击式水轮发电机组水力过渡过程的负压问题,从理论到仿真进行了深入的研究。结合实际对冲击式水轮发电机组的运行原理进行了分析,对有压管道非恒定流和引水发电系统建立数学模型,利用坐标变换方法,对运行特性进行了理论分析,并总结出冲击式机组在设计中仍应考虑存在负压问题,为水电站的实际安装工程奠定了理论基础。With the continuous improvement of hydropower resources development in China, hydropower stations are gradually transitioning to high head and large capacity impact hydro-generator sets. The Wangzigou hydropower station was took as an example to study the negative pressure problem in the hydraulic transition process of an impingement hydro-generator set. Combined with the actual operation of the hydroelectric generating set for consolidation, the principle was analyzed, and a mathematical model of the pressure pipeline unsteady flow and water power generation system was established, by using coordinate transformation method, the theoretical of operation characteristics were analyzed, and it was summed up that the impact turbine was still negative pressure problems should be considered in the design, which laid a theoretical foundation for the actual installation.
