Hydraulic Characteristics Test of the Large-Flow-Rate Pressure Forepool under Load Rejection at Xinjiang Zangao Hydropower Station
摘要
Abstract
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.关键词
