四川多水,水电资源更是富甲天下。我国规划的十三大水电基地,最大的金沙江、第三的雅砻江、第五的大渡河都在四川境内。溪洛渡、向家坝、二滩这些公众耳熟能详的水电站正像江河上璀璨的明珠熠熠生辉,为我国的经济发展贡献源源不断的清洁能源。经历了十年高速发展的四川水电,正将迎来更为辉煌的十年大跨越。目前四川已经获得核准(在建)和取得路条的1亿千瓦水电项目,大部分都将在“十二五”和“十三五”期间投产,2020年四川水电装机规模将达1.16亿千瓦。水电的高速发展使得四川电网在丰水期电力外送问题尤为显著。与之毗邻的如湖北等省份同样存在丰余枯缺的问题,而华东地区一些负荷中心距离四川水电集散地最近也超过2000公里,一般的输电线路根本无法完成如此远距离大规模的电力输送。
Sichuan more water, hydropower resources is rich in the world. The 13 major hydropower bases planned in China, the largest Jinsha River, the third Yalong River, and the fifth Dadu River are all in Sichuan. Xiluodu, Xiangjiaba, Ertan These public familiar with the hydropower station is just like bright shining pearl on the river, contributing to the continuous development of China’s economic development, clean energy. After a decade of rapid development, Sichuan Hydropower will usher in a glorious decade of leaps and bounds. At present, the 100 million-kilowatt hydropower projects in Sichuan that have been approved (under construction) and access roads, most of which will be put into operation during the “12th Five-Year Plan” and “13th Five-Year Plan” period. The installed capacity of hydropower in Sichuan in 2020 Up to 116 million kilowatts. The rapid development of hydropower makes Sichuan Power Grid in the wet period of electricity delivery problems are particularly significant. Neighboring provinces such as Hubei Province also suffer from the same shortage of power supply, while some load centers in East China have recently exceeded 2,000 kilometers from Sichuan Hydro Power Distribution Center. Transmission lines of ordinary type can not accomplish such large-scale power transmission over long distances.
