“椒小BBWBBWBBWBBW”我国沙漠线路路椒小BBWBBWBBWBBW径最长750千伏输变电工程投运

  中新椒小BBWBBWBBWBBW网新疆若羌12月14日电 (闫椒小BBWBBWBBWBBW文陆 党睿 吴涛)14日中午,随着新疆若羌750千伏变电站两台主变压器完成5次全压冲击试验,巴州—铁干里克—若羌750千伏输变电工程正式竣工投运,新疆巴州地区供电能力提升100万千瓦,新能源通道容量增加170万千瓦。

  据了解,该工程是我国“十四五”期间建成投运单体投资规模最大的750千伏输变电工程,也是我国沙漠线路路径最长的750千伏输变电工程。

  近年来,新疆围绕国家“三基地一通道”定位,大力发展可再生能源,着力构建清洁低碳、安全高效现代能源体系,推动优势资源转换,加快打造煤电油气风光储一体化示范项目和环塔里木千万千瓦级清洁能源供应保障区。

  巴州—铁干里克—若羌750千伏输变电工程作为新疆推进电气化新疆、服务丝绸之路经济带核心区建设的重点工程,是构建新疆环塔里木750千伏环网工程的重要一环。工程起自巴州750千伏变电站,止于若羌750千伏变电站,动态投资46.13亿元,于2023年3月25日开工建设,历经21个月建成投运。

  国网新疆电力有限公司建设分公司项目经理李俊说,工程有近400千米线路需要在塔克拉玛干沙漠架设。沙漠流动性大、风力强,导致沙漠铁塔基础开挖成型率极低。建设者采用垒沙袋、挡沙板等办法预防基础开挖过程出现的塌方问题,并提出“三快”施工方法(快速开挖、快速准备、快速浇筑)。这一方法大大节省了沙漠地区施工时间,也降低了施工安全风险。

  工程有176.9千米线路穿越博斯腾湖景区、台特玛湖湿地公园及胡杨林。“建设中我们将生态保护理念贯穿工程建设全过程,增加1000余万元投资,采取优化路径、增加塔高、调节档距、减少湖区塔数及搭建作业平台等方式确保电网与生态和谐相处。”李俊说。

  工程投运后,巴州若羌将形成“北接南延西连东送”的750千伏枢纽型骨干电网格局,提升疆电外送能力。在把新疆能源优势转换成经济优势的同时,有力支撑服务全国电力保供大局。同时,工程后期与若羌至且末、且末至民丰等750千伏输变电工程相连接,将形成环塔里木750千伏大环网,进一步优化新疆南部地区主网架,为塔里木盆地风光水资源开发提供网架支撑。

  据统计,截至目前,新疆电网共有750千伏变电站30座,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。(完)
