白鹤滩水电站引领水电开发跨进“双百”时代

  ◎ 溪洛渡、向家坝、乌东德、白鹤滩等4座水电站全部建成后,金沙江流域将形成一道巨大的清洁能源走廊

  ◎ 虽然按装机量和工程数量、大小来看,我国已经是世界水电第一大国,但是我国水电开发程度和发达国家相比仍有差距,还有较广阔的发展前景

继世纪工程三峡水电站之后,又一个重大水电工程走进人们视野。8月3日,世界第二大水电站——白鹤滩水电站主体工程全面开工建设。专家表示,白鹤滩水电站不仅是世界首个单机容量机组突破100万千瓦的水电站,而且是国内首个100%国产机组的大型水电站。这意味着,我国水电建设能力又跨上了一个全新的台阶。在世界能源变革和中国企业走出去的背景下,意义重大。

技术跨越实现两个“100”

云南省昆明市向北300公里,水流澎湃的金沙江下游,一片沿江绵延10余公里的区域正在紧张有序施工。超过1.3万名工人、300余公里的巨大洞室群、随处可见的高大吊塔……预示着我国又一个重大工程——白鹤滩水电站的诞生,这是世界水电在建的第一大工程,装机规模仅次于三峡,位居世界第二。

白鹤滩水电站坐落于四川省宁南县和云南省巧家县域内,是三峡集团在金沙江下游开发的4个水电梯级——乌东德、白鹤滩、溪洛渡、向家坝中的第二个梯级电站。其中,溪洛渡和向家坝电站已于2014年投产发电,乌东德电站仍在紧张施工中。

国际大坝委员会荣誉主席、中国大坝工程学会副理事长贾金生告诉记者,乌东德、溪洛渡、向家坝的水轮发电机组均有外资公司参与设计制造,而白鹤滩将成为国内首个纯国产机组的大型水电站。100万千瓦水电机组也将是世界上最大容量的高端产品,超出现有技术水平和规范,“世界范围内都无现成经验可借鉴”。

白鹤滩水电站总装机容量1600万千瓦,位列世界第二,其每一项指标都被业内认为是“世界级规模”,这个工程所要解决的难题,在世界水电工程建设史上都极具挑战性。
