4月14日23時20分，青(qing)海拉西瓦水(shui)電站(zhan)兩項750千伏送出工程正(zheng)式(shi)投(tou)入運行。西北750千伏電網工程也由(you)此迎來大規模投(tou)產(chan)高(gao)峰，今明(ming)兩年(nian)，西北750千伏電網將有“18站(zhan)53線”輸變電工程投(tou)產(chan)。
拉西(xi)瓦(wa)水電站裝機6×70萬(wan)千瓦(wa)，建成后，不僅可承擔(dan)西(xi)北電網調峰(feng)和事故(gu)備用任務，而(er)且將(jiang)在支(zhi)撐(cheng)西(xi)北千萬(wan)千瓦(wa)級(ji)風(feng)電運行(xing)、實現(xian)西(xi)北電力大規模外送中發揮(hui)重要作用。
拉(la)西瓦水電(dian)(dian)站兩(liang)項(xiang)750千伏(fu)送出工(gong)(gong)程啟動(dong)臨(lin)時(shi)方式多，操(cao)作復雜，測試難度大。為保證送出工(gong)(gong)程一(yi)次投(tou)運成(cheng)功，西北(bei)電(dian)(dian)網(wang)有限(xian)公司(si)周密組織，做好各項(xiang)準(zhun)備工(gong)(gong)作，合理調整(zheng)電(dian)(dian)網(wang)運行方式，控制相關線路(lu)潮流，圓滿完成(cheng)了啟動(dong)、投(tou)運工(gong)(gong)作。
近年來(lai)，西北(bei)公(gong)司堅持(chi)以科(ke)學發(fa)展(zhan)觀指(zhi)導電(dian)網(wang)(wang)建設，加快電(dian)網(wang)(wang)發(fa)展(zhan)方式轉變，大力實施(shi)“外向型(xing)(xing)、送(song)(song)出型(xing)(xing)、規(gui)模(mo)(mo)型(xing)(xing)”發(fa)展(zhan)戰(zhan)略，提高電(dian)網(wang)(wang)發(fa)展(zhan)質量，加快西北(bei)750千(qian)(qian)伏(fu)送(song)(song)端電(dian)網(wang)(wang)建設，推(tui)動(dong)西北(bei)大規(gui)模(mo)(mo)電(dian)力外送(song)(song)。目(mu)前，規(gui)劃中(zhong)的西北(bei)750千(qian)(qian)伏(fu)電(dian)網(wang)(wang)項目(mu)已核(he)準過半，在建項目(mu)達到(dao)“24站(zhan)47線”。到(dao)明年年底，750千(qian)(qian)伏(fu)電(dian)網(wang)(wang)規(gui)模(mo)(mo)將達到(dao)“26站(zhan)61線”，變電(dian)容量5320萬千(qian)(qian)伏(fu)安，線路(lu)10152千(qian)(qian)米(mi)，覆(fu)蓋西北(bei)五省（自治(zhi)區）的堅強750千(qian)(qian)伏(fu)送(song)(song)端電(dian)網(wang)(wang)將基本形(xing)成。
