“tobu8-HDvideo”超90%在沙tobu8-HDvideo漠 我国沙漠线路最长的750千伏输变电工程建成投运

  12月1tobu8-HDvideo4日12时55分,国网新tobu8-HDvideo疆电力若羌变电站两台750千伏主变压器顺利完成五次全压冲击试验后正式带电运行,标志着我国“十四五”期间单体投资规模最大的750千伏输变电工程建成投运,这也是我国沙漠线路路径最长的750千伏输变电工程。

  新疆巴州—铁干里克—若羌750千伏输变电工程自新疆巴州750千伏变电站起,途经焉耆县、库尔勒市、铁门关市等地到达若羌750千伏变电站。动态投资46.13亿元,新建750千伏线路长度880公里、变电站两座、铁塔1873基。

  作为我国沙漠线路路径最长的750千伏输变电工程,工程超过90%的线路都在塔克拉玛干沙漠南部,有近400公里线路从沙漠中穿过,还有近二百公里从博斯腾湖景区、台特玛湖湿地及大片胡杨林中穿过。建设人员增加1000多万元投资,通过优化路径、增加塔高、减少塔数及搭建作业平台等方式,确保工程与生态和谐共处。建设人员还在新疆巴州若羌县建成南疆首个750千伏GIS变电站,即气体绝缘变电站。

  据了解,新疆巴州—铁干里克—若羌750千伏输变电工程投运后,将大幅提升南疆光伏等新能源汇集送出能力,满足全国单体最大的光伏新能源电厂并网条件,有力支撑新疆第三条交流、第四条直流外送通道的建设,推进新疆和青海大电网互联。工程后期还将与若羌至且末、且末至民丰等750千伏输变电工程相连接,形成环塔里木750千伏大环网,进一步优化新疆南部地区主网架,为塔里木盆地煤电油气风光储资源开发提供网架支撑。

  截至12月14日,新疆电网共建成750千伏变电站30座,变电容量8750.4万千伏安,线路91条12037千米,形成“内供五环网、外送四通道”主网架格局。按照规划,“十四五”末,新疆电网将形成“内供七环网、外送五通道”的主网架格局,为新疆能源优势转换为经济优势提供强大动能。
