4月14日(ri)23時(shi)20分，青海拉西(xi)瓦水電站(zhan)兩(liang)項750千(qian)(qian)(qian)伏(fu)送出工(gong)程正式投入(ru)運行。西(xi)北750千(qian)(qian)(qian)伏(fu)電網工(gong)程也(ye)由此迎來大規模投產高峰，今明兩(liang)年(nian)，西(xi)北750千(qian)(qian)(qian)伏(fu)電網將有(you)“18站(zhan)53線”輸變電工(gong)程投產。
拉(la)西瓦水電站裝機6×70萬千瓦，建成后，不僅可承(cheng)擔(dan)西北(bei)(bei)電網調(diao)峰和事故備(bei)用(yong)任務，而且將在支撐西北(bei)(bei)千萬千瓦級(ji)風電運(yun)行、實現西北(bei)(bei)電力大規模外送(song)中發揮(hui)重要作用(yong)。
拉西(xi)瓦水電(dian)(dian)站兩項750千伏送(song)出工(gong)程(cheng)啟動(dong)臨(lin)時方式多，操作復雜，測試難度(du)大。為保(bao)證送(song)出工(gong)程(cheng)一次投運(yun)成功，西(xi)北電(dian)(dian)網有限(xian)公(gong)司(si)周(zhou)密組(zu)織(zhi)，做好各項準備工(gong)作，合(he)理調整電(dian)(dian)網運(yun)行(xing)方式，控制相關線路潮(chao)流(liu)，圓(yuan)滿完成了啟動(dong)、投運(yun)工(gong)作。
近年來，西北公司堅持以科學發(fa)(fa)展觀指(zhi)導電(dian)(dian)(dian)網(wang)建設，加快(kuai)電(dian)(dian)(dian)網(wang)發(fa)(fa)展方式轉變，大(da)力(li)(li)實施“外向型、送(song)(song)出型、規(gui)(gui)模(mo)型”發(fa)(fa)展戰略，提高(gao)電(dian)(dian)(dian)網(wang)發(fa)(fa)展質量，加快(kuai)西北750千(qian)伏(fu)送(song)(song)端(duan)電(dian)(dian)(dian)網(wang)建設，推動西北大(da)規(gui)(gui)模(mo)電(dian)(dian)(dian)力(li)(li)外送(song)(song)。目前，規(gui)(gui)劃中的西北750千(qian)伏(fu)電(dian)(dian)(dian)網(wang)項(xiang)目已核準過半，在建項(xiang)目達(da)到(dao)“24站(zhan)47線(xian)”。到(dao)明年年底，750千(qian)伏(fu)電(dian)(dian)(dian)網(wang)規(gui)(gui)模(mo)將(jiang)達(da)到(dao)“26站(zhan)61線(xian)”，變電(dian)(dian)(dian)容(rong)量5320萬千(qian)伏(fu)安，線(xian)路10152千(qian)米，覆蓋西北五省(sheng)（自治區(qu)）的堅強750千(qian)伏(fu)送(song)(song)端(duan)電(dian)(dian)(dian)網(wang)將(jiang)基本形(xing)成(cheng)。
