“白鹤”亮“翅”,带来哪些看点?

2017-08-04 07:48:56   中国青年网

三峡集团开发建设的金沙江下游四个巨型水电梯级电站,溪洛渡、向家坝水电站已建成投产;乌东德、白鹤滩也将以“姐妹花”的方式亮相,装机规模达2620万千瓦,相当于“再造一个三峡工程”。

“金沙江下游四座巨型水电站形成两组电源组合。”三峡集团白鹤滩工程建设部相关负责人介绍。

乌东德、白鹤滩这对“姐妹花”,位置相距182公里,相当于成都到内江的距离。装机规模,一个世界第七,一个世界第二,加起来可以跟世界第一的三峡电站有得一拼。两座电站多年平均发电量逾1000亿千瓦时,超过三峡电站设计发电量。

“形成电源组合有很多好处。”三峡集团建设管理公司相关负责人介绍,首先是联合发电的效益,乌东德建成后可增加下游三个梯级年发电量2亿千瓦时,白鹤滩建成后可增加下游梯级电站年发电量24.3亿千瓦时。

“姐妹花”可联合防洪。两个电站水库防洪库容99.4亿立方米,是三峡防洪库容的45%。可与金沙江下游溪洛渡、向家坝水库联合运用,使宜宾、泸州、重庆等城市的防洪标准进一步提高。中国工程院院士王浩告诉记者,金沙江下游的四座巨型水电站建成后,防洪库容达到200多亿立方米,可以进一步减轻三峡水库的防洪压力。

还有联合经济社会效益。乌东德、白鹤滩动态总投资加起来近3000亿元,能拉动数千亿社会投资,创造数万个就业岗位,推动约13万水库移民实现脱贫致富。

按照规划,乌东德水电站2021年全部机组投产发电,白鹤滩水电站2022年全部机组投产。届时,这对“姐妹花”将联手“再造一个三峡工程”。
