4月14日23時(shi)20分，青(qing)海拉(la)西瓦水(shui)電站兩項750千(qian)(qian)伏(fu)送出工(gong)程(cheng)正(zheng)式投入運行。西北750千(qian)(qian)伏(fu)電網(wang)工(gong)程(cheng)也(ye)由此迎來大(da)規模投產(chan)高峰，今明兩年，西北750千(qian)(qian)伏(fu)電網(wang)將有“18站53線”輸變電工(gong)程(cheng)投產(chan)。
拉(la)西(xi)瓦水電(dian)站(zhan)裝機6×70萬(wan)千(qian)瓦，建成后，不僅可(ke)承(cheng)擔西(xi)北電(dian)網調(diao)峰和(he)事故備(bei)用任務，而且(qie)將在(zai)支撐西(xi)北千(qian)萬(wan)千(qian)瓦級(ji)風電(dian)運行、實現(xian)西(xi)北電(dian)力大(da)規模外送中發(fa)揮重要作用。
拉西瓦水(shui)電站兩(liang)項750千伏送出工(gong)(gong)程啟(qi)動臨(lin)時方(fang)式多，操作復雜，測試難(nan)度大。為保(bao)證送出工(gong)(gong)程一次投運(yun)成功，西北電網(wang)有(you)限(xian)公司周密組織，做好(hao)各項準備工(gong)(gong)作，合理調整電網(wang)運(yun)行方(fang)式，控制相關線路潮流，圓滿(man)完成了啟(qi)動、投運(yun)工(gong)(gong)作。
近年來，西北(bei)(bei)公司堅持以科學(xue)發(fa)展(zhan)觀指導電(dian)(dian)(dian)網(wang)(wang)建設(she)，加(jia)快電(dian)(dian)(dian)網(wang)(wang)發(fa)展(zhan)方式轉變，大力(li)(li)實施“外(wai)向型、送(song)(song)出型、規模型”發(fa)展(zhan)戰(zhan)略，提(ti)高電(dian)(dian)(dian)網(wang)(wang)發(fa)展(zhan)質量(liang)，加(jia)快西北(bei)(bei)750千(qian)(qian)伏送(song)(song)端(duan)電(dian)(dian)(dian)網(wang)(wang)建設(she)，推(tui)動西北(bei)(bei)大規模電(dian)(dian)(dian)力(li)(li)外(wai)送(song)(song)。目(mu)前(qian)，規劃中的(de)西北(bei)(bei)750千(qian)(qian)伏電(dian)(dian)(dian)網(wang)(wang)項(xiang)目(mu)已核(he)準過(guo)半，在(zai)建項(xiang)目(mu)達到(dao)“24站(zhan)47線(xian)”。到(dao)明年年底，750千(qian)(qian)伏電(dian)(dian)(dian)網(wang)(wang)規模將達到(dao)“26站(zhan)61線(xian)”，變電(dian)(dian)(dian)容量(liang)5320萬千(qian)(qian)伏安，線(xian)路10152千(qian)(qian)米，覆蓋西北(bei)(bei)五省（自(zi)治(zhi)區）的(de)堅強750千(qian)(qian)伏送(song)(song)端(duan)電(dian)(dian)(dian)網(wang)(wang)將基本形成。
