摘　　要：姚河坝电站为日调节水库 ,采用汛期降低水位进行沉沙及定期停机排沙的运行方式 ,用以取代常规沉沙池 ,是具有创新性的新成果。水库的日调节特性 ,使本电站电能质量优良 ,也使已建成的下游两个径流式电站基荷运行能转化为同步调峰运行 。In the daily storage plant , desilting by lowering water level during flood season and regular sediment discharging during shutdown period are carried out instead of common silt basin. The daily reservoir results in high quality power energy and conversion of base load operation into synchronous peak load operation in the existing two run-of-river power stations downstream , therefore, high operation efficiency .
