4月14日(ri)23時20分，青(qing)海拉西瓦(wa)水(shui)電站(zhan)(zhan)兩項(xiang)750千伏送出工程正式投入運行。西北750千伏電網工程也由(you)此(ci)迎來大(da)規模投產高(gao)峰(feng)，今(jin)明兩年，西北750千伏電網將有(you)“18站(zhan)(zhan)53線”輸變(bian)電工程投產。
拉西(xi)瓦水電(dian)站裝機6×70萬千瓦，建(jian)成后，不(bu)僅(jin)可承(cheng)擔西(xi)北電(dian)網調峰(feng)和事故備用任務，而且將在支(zhi)撐西(xi)北千萬千瓦級風(feng)電(dian)運行、實現西(xi)北電(dian)力大規模外送(song)中發(fa)揮重要作用。
拉西瓦水電站兩項(xiang)750千(qian)伏送出工程啟動臨時方式(shi)(shi)多，操(cao)作復(fu)雜，測試(shi)難度大。為保(bao)證送出工程一次(ci)投運成功，西北電網(wang)有限公司(si)周密組織，做好各項(xiang)準(zhun)備工作，合理調(diao)整(zheng)電網(wang)運行方式(shi)(shi)，控制(zhi)相關線(xian)路潮流，圓滿完成了(le)啟動、投運工作。
近年(nian)來，西北公(gong)司堅(jian)持以科學發(fa)展(zhan)觀指導電(dian)(dian)(dian)(dian)網建(jian)設，加快電(dian)(dian)(dian)(dian)網發(fa)展(zhan)方式轉變(bian)，大(da)力(li)實施“外(wai)向型、送(song)出型、規模(mo)型”發(fa)展(zhan)戰略，提高(gao)電(dian)(dian)(dian)(dian)網發(fa)展(zhan)質量，加快西北750千(qian)(qian)(qian)伏(fu)送(song)端電(dian)(dian)(dian)(dian)網建(jian)設，推動西北大(da)規模(mo)電(dian)(dian)(dian)(dian)力(li)外(wai)送(song)。目(mu)(mu)前(qian)，規劃中的西北750千(qian)(qian)(qian)伏(fu)電(dian)(dian)(dian)(dian)網項目(mu)(mu)已核準過半(ban)，在建(jian)項目(mu)(mu)達到“24站47線(xian)”。到明年(nian)年(nian)底，750千(qian)(qian)(qian)伏(fu)電(dian)(dian)(dian)(dian)網規模(mo)將達到“26站61線(xian)”，變(bian)電(dian)(dian)(dian)(dian)容(rong)量5320萬千(qian)(qian)(qian)伏(fu)安，線(xian)路10152千(qian)(qian)(qian)米(mi)，覆蓋(gai)西北五省（自治區）的堅(jian)強750千(qian)(qian)(qian)伏(fu)送(song)端電(dian)(dian)(dian)(dian)網將基本形成(cheng)。
