摘　　要：錾高水电站工程为大流量引水式电站,渠道设计流量375.6 m^(3)/s,总线路长8.6 km,工程规模大,渠道线路长。在电站甩负荷紧急关机的情况下,引水渠首的控制闸门难以实现同时关闭。因此,紧急关机产生水击波在前池形成涌浪和引水渠持续来流将使前池水位升高。若水位超过前池边墙,将威胁厂房安全。甩负荷试验的目的为:①确定前池各工况最高涌波水位;②确定连接压力前池输水系统超高,尽可能使压力前池及输水系统的设计安全可靠且经济合理。Zangao Hydropower Station project is a high flow diversion type power station,with a designed channel flow of 375.6m3/s and a total bus length of 8.6km.The project has a large scale and a long channel route.In the case of emergency shutdown due to load shedding in the power station,it is difficult to achieve simultaneous closure of the control gates at the head of the diversion canal.Therefore,the emergency shutdown generates water hammer waves that form surges in the forebay and the continuous inflow of the diversion channel will cause the water level in the forebay to rise.If the water level exceeds the front pool wall,it will threaten the safety of the factory building.The purpose of the load rejection test is to determine the highest surge water level in each working condition of the forebay,and to determine the superelevation of the connected pressure forebay water delivery system,in order to make the design of the pressure forebay and water delivery system as safe,reliable,and economically reasonable as possible.
