向家坝水电站左右岸共安装8台机组,单机容量80万千瓦,总装机640万千瓦,就单机容量而言,为世界之首,就装机容量而言,是目前我国在建和已建水电站中的第三大水电站,仅次于三峡水电站、溪洛渡水电站。向家坝水电站是一座以发电为主,同时改善航运条件,兼有防洪、灌溉,并具有拦沙和对溪洛渡水电站进行反调节等综合效益的巨型电站。电站控制流域面积45.88万平方公里,占金沙江流域的97%,正常蓄水位380米,总库容51.6亿立方米,调节库容9亿立方米,为不完全季调节水库。
There are 8 generating units installed around Xiangjiaba Hydropower Station. The unit capacity is 800,000 kilowatts and the total installed capacity is 6.4 million kilowatts. In terms of stand-alone capacity, it is the first in the world. As far as installed capacity is concerned, In the third largest hydropower station, second only to the Three Gorges Hydropower Station, Xiluodu Hydropower Station. Xiangjiaba Hydropower Station is a giant power plant with comprehensive benefits such as power generation and improved shipping conditions, flood control and irrigation, anti-sediment control and anti-adjustment to Xiluodu Hydropower Station. The power control basin covers an area of 458,800 square kilometers, accounting for 97% of the Jinsha River Basin. The normal water level is 380 meters and the total storage capacity is 5.16 billion cubic meters. The reservoir capacity is adjusted to 900 million cubic meters to regulate the reservoir.
