向家坝水电站是金沙江下游梯级电站开发中的最末一个梯级电站,位于四川省宜宾县、云南省水富县境内。电站的开发任务以发电为主,同时改善上下游通航条件,结合防洪和拦沙,兼顾灌溉和漂木,并且具有为上游梯级电站进行反调节作用。电站为混凝土重力坝,最大坝高162m,总装机容量6400MW,正常蓄水位380.00m,总库容51.63亿m~3,调节库容9.03亿m~3。
Xiangjiaba Hydropower Station is the last cascade power station in the development of cascade hydropower stations in the lower reaches of the Jinsha River. It is located in Yibin County, Sichuan Province and Shuifu County, Yunnan Province. Power station development tasks to power generation, while improving upstream and downstream navigation conditions, combined with flood control and sediment blocking, taking into account the irrigation and drift wood, and for the upstream cascade power plant anti-regulatory role. The power station is a concrete gravity dam with a maximum dam height of 162m, a total installed capacity of 6400MW, a normal water storage level of 380.00m and a total storage capacity of 5.163 billion m 3, with a total storage capacity of 903 million m 3.
