4月14日23時20分，青海拉西瓦(wa)水電站(zhan)兩項750千(qian)伏送出工程(cheng)正式投入運行(xing)。西北750千(qian)伏電網工程(cheng)也由此迎(ying)來大規模投產高峰，今(jin)明兩年，西北750千(qian)伏電網將有“18站(zhan)53線”輸變(bian)電工程(cheng)投產。
拉西(xi)(xi)瓦水電(dian)站裝(zhuang)機6×70萬(wan)千(qian)瓦，建成后，不僅可承擔西(xi)(xi)北電(dian)網(wang)調峰和事故備用(yong)任務，而且將(jiang)在支(zhi)撐西(xi)(xi)北千(qian)萬(wan)千(qian)瓦級風(feng)電(dian)運行、實現西(xi)(xi)北電(dian)力大規(gui)模外(wai)送中發揮重要作(zuo)用(yong)。
拉西瓦水電(dian)(dian)站兩項750千伏(fu)送出工(gong)程啟(qi)動臨時方(fang)式多，操作(zuo)(zuo)復雜(za)，測試難度大。為保(bao)證送出工(gong)程一次投運成功(gong)，西北電(dian)(dian)網有(you)限公司周密組織，做(zuo)好各項準(zhun)備工(gong)作(zuo)(zuo)，合(he)理調整電(dian)(dian)網運行方(fang)式，控制相(xiang)關(guan)線路潮(chao)流，圓滿完(wan)成了(le)啟(qi)動、投運工(gong)作(zuo)(zuo)。
近年(nian)來，西(xi)北(bei)公(gong)司堅持以科學發(fa)(fa)展觀指(zhi)導電(dian)(dian)網(wang)(wang)(wang)建設，加快電(dian)(dian)網(wang)(wang)(wang)發(fa)(fa)展方式轉變(bian)，大力(li)實施“外向型、送(song)出(chu)型、規(gui)模型”發(fa)(fa)展戰(zhan)略，提高電(dian)(dian)網(wang)(wang)(wang)發(fa)(fa)展質量，加快西(xi)北(bei)750千伏(fu)送(song)端電(dian)(dian)網(wang)(wang)(wang)建設，推動西(xi)北(bei)大規(gui)模電(dian)(dian)力(li)外送(song)。目(mu)(mu)前(qian)，規(gui)劃中的(de)(de)西(xi)北(bei)750千伏(fu)電(dian)(dian)網(wang)(wang)(wang)項目(mu)(mu)已(yi)核準過(guo)半，在(zai)建項目(mu)(mu)達到(dao)(dao)“24站47線(xian)(xian)(xian)”。到(dao)(dao)明年(nian)年(nian)底，750千伏(fu)電(dian)(dian)網(wang)(wang)(wang)規(gui)模將達到(dao)(dao)“26站61線(xian)(xian)(xian)”，變(bian)電(dian)(dian)容量5320萬千伏(fu)安，線(xian)(xian)(xian)路10152千米，覆(fu)蓋西(xi)北(bei)五省(sheng)（自治區）的(de)(de)堅強750千伏(fu)送(song)端電(dian)(dian)網(wang)(wang)(wang)將基本形成。
