摘　　要：受自身特点影响,抽水蓄能电站的系统倒送电启动试验存在重大隐患。在倒送电启动试验中,保护装置无法进行带负荷校验,其可靠性无法得以验证,一旦并网投运,将对电网运行及机组调试的安全产生不利影响。本文提出了一种利用试验负载校验保护装置的对策,并通过实例演算论证了其可行性。Due to the characteristic of pumped-storage power station,a big hidden trouble will occur when the inverse power supply test performed. During the inverse power supply,load test can＇t be carried out for the protection device in power station. The reliability of the protection device can＇t be verified. Once the power station incorporated into the power grid,the safety of the power grid and the generator unit＇s start-up test will be threatened. A countermeasure is provided to on-load test the protection device by using testing load,the feasibility of which is demonstrated on the case of a real pumped-storage power station.
