摘　　要：通过对甘肃电投九甸峡水电开发有限责任公司负责开发和经营的洮河流域段九甸峡～三甲水电站发电量的分析,得出九甸峡水利枢纽建成后,下游梯级电站年发电量增加2.27%,引洮工程一、二期引水后,对下游电站发电量减少起到补偿作用;对入库洪水进行调节后,能够对下游电站起到滞洪和消减洪峰的作用。The impacts on the power generation of the downstream five cascade hydropower stations in Taohe River caused by the construction of Jiudianxia Water Project were analyzed,and the conclusion shows that the annual generation will have an increase of 2.27% and the increase will be able to compensate the generating losses caused by the water diversion of Taohe Diversion Project I and II.The Jiudianxia Project can also delay and reduce the flood peak for downstream stations.
