4月14日23時20分(fen)，青海拉西(xi)瓦(wa)水電(dian)站(zhan)兩項750千(qian)伏(fu)送出工程(cheng)(cheng)正(zheng)式投(tou)入運行。西(xi)北750千(qian)伏(fu)電(dian)網工程(cheng)(cheng)也由此迎來(lai)大規模(mo)投(tou)產高峰，今明(ming)兩年(nian)，西(xi)北750千(qian)伏(fu)電(dian)網將有“18站(zhan)53線(xian)”輸變(bian)電(dian)工程(cheng)(cheng)投(tou)產。
拉(la)西(xi)瓦(wa)水電(dian)(dian)站裝機6×70萬千瓦(wa)，建(jian)成后，不僅(jin)可(ke)承擔西(xi)北電(dian)(dian)網調(diao)峰和(he)事故(gu)備用(yong)任務，而(er)且將在支撐西(xi)北千萬千瓦(wa)級(ji)風電(dian)(dian)運行、實(shi)現(xian)西(xi)北電(dian)(dian)力(li)大規模外送中發揮重要(yao)作用(yong)。
拉西瓦(wa)水電站兩項750千伏送(song)出工(gong)(gong)程啟動臨時方式多，操(cao)作(zuo)復雜，測(ce)試(shi)難度大(da)。為(wei)保證送(song)出工(gong)(gong)程一次投運(yun)成功，西北電網有限(xian)公司(si)周(zhou)密組(zu)織，做好各項準備工(gong)(gong)作(zuo)，合理調整電網運(yun)行方式，控制相關線(xian)路潮流，圓滿完成了啟動、投運(yun)工(gong)(gong)作(zuo)。
近(jin)年(nian)來，西(xi)北公司堅(jian)(jian)持以(yi)科學(xue)發展(zhan)觀指(zhi)導電(dian)(dian)網建設(she)，加快(kuai)電(dian)(dian)網發展(zhan)方(fang)式轉變(bian)，大力實施“外向型、送(song)(song)出型、規(gui)(gui)模型”發展(zhan)戰略，提高電(dian)(dian)網發展(zhan)質量，加快(kuai)西(xi)北750千(qian)伏送(song)(song)端電(dian)(dian)網建設(she)，推動西(xi)北大規(gui)(gui)模電(dian)(dian)力外送(song)(song)。目前，規(gui)(gui)劃中的西(xi)北750千(qian)伏電(dian)(dian)網項目已核準過半，在(zai)建項目達到(dao)(dao)“24站47線(xian)”。到(dao)(dao)明年(nian)年(nian)底(di)，750千(qian)伏電(dian)(dian)網規(gui)(gui)模將(jiang)(jiang)達到(dao)(dao)“26站61線(xian)”，變(bian)電(dian)(dian)容量5320萬千(qian)伏安(an)，線(xian)路10152千(qian)米，覆蓋西(xi)北五(wu)省（自(zi)治區）的堅(jian)(jian)強750千(qian)伏送(song)(song)端電(dian)(dian)網將(jiang)(jiang)基(ji)本形(xing)成。
