為促進全國范圍(wei)內(nei)能源資(zi)源優化配置(zhi)，近日，國家發改委批復(fu)核準建(jian)設西(xi)北(bei)(bei)（陜西(xi)寶雞(ji)）至華(hua)中(zhong)（四川德陽）直流聯(lian)網(wang)(wang)工程，這(zhe)是西(xi)北(bei)(bei)電(dian)網(wang)(wang)與華(hua)中(zhong)電(dian)網(wang)(wang)實現聯(lian)網(wang)(wang)的第二條輸(shu)變電(dian)線路，標(biao)志著西(xi)北(bei)(bei)電(dian)力外送通(tong)道建(jian)設又取得重大(da)進展。
西(xi)北(bei)(bei)(bei)地(di)區擁有(you)豐富的火電(dian)(dian)(dian)(dian)(dian)、水電(dian)(dian)(dian)(dian)(dian)、風電(dian)(dian)(dian)(dian)(dian)等資源(yuan)。自2005年(nian)始西(xi)北(bei)(bei)(bei)地(di)區電(dian)(dian)(dian)(dian)(dian)力已出現富余，去年(nian)富余電(dian)(dian)(dian)(dian)(dian)量300多億千瓦時，西(xi)北(bei)(bei)(bei)地(di)區迫切需要電(dian)(dian)(dian)(dian)(dian)力外(wai)送。為此，國家電(dian)(dian)(dian)(dian)(dian)網公(gong)司提(ti)出加(jia)快規(gui)劃(hua)建(jian)設(she)西(xi)北(bei)(bei)(bei)送端電(dian)(dian)(dian)(dian)(dian)網。西(xi)北(bei)(bei)(bei)（陜西(xi)寶雞）至華(hua)(hua)中（四川(chuan)德陽）直流聯網工程(cheng)，是西(xi)北(bei)(bei)(bei)電(dian)(dian)(dian)(dian)(dian)網“十一(yi)五”期(qi)(qi)間規(gui)劃(hua)建(jian)設(she)的4條外(wai)送電(dian)(dian)(dian)(dian)(dian)聯網工程(cheng)之一(yi)。2007年(nian)9月國家發改委批復(fu)同意西(xi)北(bei)(bei)(bei)（銀川(chuan)東(dong)(dong)）與華(hua)(hua)北(bei)(bei)(bei)（山東(dong)(dong)）聯網工程(cheng)開(kai)展前期(qi)(qi)工作(zuo)，同年(nian)12月國家發改委核準(zhun)了(le)西(xi)北(bei)(bei)(bei)（陜西(xi)羅夫）與華(hua)(hua)中（河南(nan)靈寶）背靠背輸(shu)電(dian)(dian)(dian)(dian)(dian)擴建(jian)工程(cheng)。西(xi)北(bei)(bei)(bei)（青海格爾木）至西(xi)藏直流聯網輸(shu)變(bian)電(dian)(dian)(dian)(dian)(dian)工程(cheng)前期(qi)(qi)工作(zuo)正在加(jia)緊(jin)開(kai)展。
這次核(he)準的西北至華中(zhong)聯網(wang)(wang)工(gong)程在(zai)陜西電(dian)網(wang)(wang)及西北電(dian)網(wang)(wang)中(zhong)處于重要(yao)位置，是西北送(song)端(duan)電(dian)網(wang)(wang)建設的重要(yao)通道。該工(gong)程由國家電(dian)網(wang)(wang)公司直(zhi)接投(tou)資，主要(yao)包(bao)括新建寶(bao)雞、德陽(yang)換流(liu)站，容量300萬千瓦；建設寶(bao)雞換流(liu)站至德陽(yang)換流(liu)站1回±500千伏(fu)直(zhi)流(liu)線路，線路長度約574千米。
工程建成后，將(jiang)進一步加強西北與(yu)(yu)華中電(dian)網之間(jian)的聯系，有利于陜西電(dian)網與(yu)(yu)四川電(dian)網之間(jian)的相互備用(yong)和(he)事故(gu)支援，并促進能源資(zi)源在(zai)更大范圍(wei)內優化配置(zhi)，對于推動(dong)西部經濟社(she)會全面(mian)發展將(jiang)發揮(hui)重要作用(yong)。
目前(qian)(qian)，西北電網(wang)有(you)限(xian)公司正(zheng)在加快750千伏電網(wang)配套工(gong)程建設和陜西寶(bao)雞換(huan)流站的前(qian)(qian)期建設準備(bei)，積極(ji)做好相(xiang)關配合工(gong)作，力爭該直流聯網(wang)工(gong)程早日開工(gong)建設。
