金沙江是我国规划的具有重要战略地位最大水电基地,开发金沙江水能资源对实现西电东送,优化和改善华中和华东地区能源结构,发展西南地区的经济,充分发挥三峡工程的效益,减少三峡水库的泥沙淤积,都具有重要的意义。 向家坝水电站是金江江梯级现划最末一级,位于宜宾市上游33公里,在四川省屏山县和云南省水富县交界处。正常蓄水位380米,最大坝高151米,总库容54.2亿立方米,装机容量600万千瓦,年发电量307.4亿千瓦时。 溪落渡水电站是金沙江规划自下而上第二级,位于宜宾市上游184公里,在四川省雷波县和云南省永善县交界处。正常蓄水位610米,最大坝高295米,总库容140.2亿立方米,装机容量1440万千瓦,年发电量621.6亿千瓦时。 向家坝和溪落渡两座水电站,共计装机容量2040万千瓦,年
The Jinsha River is the largest strategic hydropower station in China that is strategically planned. The development of the Jinsha River hydropower resources will help realize the West-to-East power transmission, optimize and improve the energy structure in Central and East China, develop the economy of the Southwest, and give full play to the benefits of the Three Gorges Project. The sedimentation of the Three Gorges Reservoir is of great significance. The Xiangjiaba Hydropower Station is the lowest level of the Jinjiang River cascade. It is located 33 kilometers upstream of Yibin City, at the junction of Pingshan County in Sichuan Province and Shuifu County in Yunnan Province. The normal water level is 380 meters, the maximum dam height is 151 meters, the total storage capacity is 5.42 billion cubic meters, the installed capacity is 6 million kilowatts, and the annual power generation capacity is 30.74 billion kwh. Xiludu Hydropower Station is the second level from the bottom of the Jinsha River planning, located 184 kilometers upstream of Yibin City, at the junction of Leibo County of Sichuan Province and Yongshan County of Yunnan Province. The normal water level of 610 meters, the maximum dam height of 295 meters, the total capacity of 14.02 billion cubic meters, installed capacity of 14.4 million kilowatts, annual power generation capacity of 62.16 billion kwh. Two hydropower stations were connected to Xiangjiaba and Xixi, with a total installed capacity of 20.4 million kilowatts.
