為促進全國范圍內能源資源優化(hua)配置，近日，國家(jia)發改委批復核準建(jian)設西北（陜(shan)西寶(bao)雞）至(zhi)華(hua)中(zhong)（四川(chuan)德陽）直(zhi)流聯網工程，這是西北電(dian)(dian)網與(yu)華(hua)中(zhong)電(dian)(dian)網實現聯網的第二條輸變電(dian)(dian)線(xian)路，標志著西北電(dian)(dian)力外送通道建(jian)設又(you)取得(de)重大(da)進展。
西(xi)(xi)(xi)(xi)北(bei)地區(qu)(qu)擁有豐(feng)富(fu)的火電(dian)(dian)(dian)(dian)、水(shui)電(dian)(dian)(dian)(dian)、風電(dian)(dian)(dian)(dian)等資源。自2005年(nian)始(shi)西(xi)(xi)(xi)(xi)北(bei)地區(qu)(qu)電(dian)(dian)(dian)(dian)力(li)已出(chu)現富(fu)余，去年(nian)富(fu)余電(dian)(dian)(dian)(dian)量300多(duo)億(yi)千(qian)瓦時，西(xi)(xi)(xi)(xi)北(bei)地區(qu)(qu)迫切需要電(dian)(dian)(dian)(dian)力(li)外送。為(wei)此，國(guo)家(jia)電(dian)(dian)(dian)(dian)網(wang)(wang)公司(si)提出(chu)加快規劃建設(she)西(xi)(xi)(xi)(xi)北(bei)送端電(dian)(dian)(dian)(dian)網(wang)(wang)。西(xi)(xi)(xi)(xi)北(bei)（陜西(xi)(xi)(xi)(xi)寶雞）至華(hua)中(zhong)（四川德陽(yang)）直(zhi)流聯網(wang)(wang)工(gong)程(cheng)，是西(xi)(xi)(xi)(xi)北(bei)電(dian)(dian)(dian)(dian)網(wang)(wang)“十一(yi)(yi)五”期間規劃建設(she)的4條外送電(dian)(dian)(dian)(dian)聯網(wang)(wang)工(gong)程(cheng)之(zhi)一(yi)(yi)。2007年(nian)9月國(guo)家(jia)發改委(wei)批復同(tong)意西(xi)(xi)(xi)(xi)北(bei)（銀川東(dong)）與(yu)華(hua)北(bei)（山(shan)東(dong)）聯網(wang)(wang)工(gong)程(cheng)開(kai)展前(qian)期工(gong)作，同(tong)年(nian)12月國(guo)家(jia)發改委(wei)核準了西(xi)(xi)(xi)(xi)北(bei)（陜西(xi)(xi)(xi)(xi)羅(luo)夫）與(yu)華(hua)中(zhong)（河南靈(ling)寶）背靠背輸電(dian)(dian)(dian)(dian)擴(kuo)建工(gong)程(cheng)。西(xi)(xi)(xi)(xi)北(bei)（青海格爾木）至西(xi)(xi)(xi)(xi)藏直(zhi)流聯網(wang)(wang)輸變電(dian)(dian)(dian)(dian)工(gong)程(cheng)前(qian)期工(gong)作正在加緊開(kai)展。
這(zhe)次核(he)準(zhun)的(de)西(xi)北至華中聯網(wang)工(gong)程在(zai)陜西(xi)電(dian)(dian)網(wang)及西(xi)北電(dian)(dian)網(wang)中處(chu)于(yu)重(zhong)要位置，是西(xi)北送端電(dian)(dian)網(wang)建(jian)設的(de)重(zhong)要通道。該工(gong)程由國家電(dian)(dian)網(wang)公司直(zhi)接投資，主要包括(kuo)新建(jian)寶雞(ji)、德陽(yang)換(huan)(huan)流站，容(rong)量300萬千瓦；建(jian)設寶雞(ji)換(huan)(huan)流站至德陽(yang)換(huan)(huan)流站1回(hui)±500千伏直(zhi)流線路，線路長(chang)度約574千米。
工(gong)程建成后，將進一(yi)步(bu)加強西北(bei)與華中電(dian)網之間的聯(lian)系，有利于陜西電(dian)網與四(si)川電(dian)網之間的相互備用(yong)和事故(gu)支援，并(bing)促(cu)進能(neng)源資源在更(geng)大范圍內優化配置，對于推動西部經濟(ji)社(she)會全面發展(zhan)將發揮(hui)重要作用(yong)。
目前(qian)，西北(bei)電網(wang)有限(xian)公司正在(zai)加快750千伏(fu)電網(wang)配套工(gong)(gong)程建(jian)(jian)設和陜西寶雞(ji)換流站的(de)前(qian)期建(jian)(jian)設準備(bei)，積極做好相關配合工(gong)(gong)作，力爭該直(zhi)流聯網(wang)工(gong)(gong)程早日開工(gong)(gong)建(jian)(jian)設。
