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(wei)批復核準建(jian)(jian)設西北（陜西寶雞）至華中（四(si)川德(de)陽）直流聯網(wang)(wang)工(gong)程，這是西北電(dian)網(wang)(wang)與華中電(dian)網(wang)(wang)實現聯網(wang)(wang)的第二條輸(shu)變電(dian)線路，標(biao)志著西北電(dian)力(li)外(wai)送通(tong)道建(jian)(jian)設又取(qu)得重大進展。
西(xi)(xi)(xi)北(bei)地(di)區擁有豐富(fu)的(de)火(huo)電(dian)(dian)(dian)、水(shui)電(dian)(dian)(dian)、風(feng)電(dian)(dian)(dian)等資(zi)源。自2005年(nian)始西(xi)(xi)(xi)北(bei)地(di)區電(dian)(dian)(dian)力已出現富(fu)余，去(qu)年(nian)富(fu)余電(dian)(dian)(dian)量300多(duo)億(yi)千(qian)瓦(wa)時，西(xi)(xi)(xi)北(bei)地(di)區迫切(qie)需要電(dian)(dian)(dian)力外送。為此(ci)，國(guo)家電(dian)(dian)(dian)網(wang)(wang)(wang)公司提出加快(kuai)規劃建(jian)(jian)設西(xi)(xi)(xi)北(bei)送端電(dian)(dian)(dian)網(wang)(wang)(wang)。西(xi)(xi)(xi)北(bei)（陜西(xi)(xi)(xi)寶雞）至華(hua)中（四川德陽）直流聯網(wang)(wang)(wang)工(gong)(gong)程，是西(xi)(xi)(xi)北(bei)電(dian)(dian)(dian)網(wang)(wang)(wang)“十一五(wu)”期(qi)間規劃建(jian)(jian)設的(de)4條外送電(dian)(dian)(dian)聯網(wang)(wang)(wang)工(gong)(gong)程之一。2007年(nian)9月國(guo)家發改(gai)委(wei)批(pi)復同意西(xi)(xi)(xi)北(bei)（銀川東）與華(hua)北(bei)（山東）聯網(wang)(wang)(wang)工(gong)(gong)程開展前期(qi)工(gong)(gong)作，同年(nian)12月國(guo)家發改(gai)委(wei)核準(zhun)了西(xi)(xi)(xi)北(bei)（陜西(xi)(xi)(xi)羅夫）與華(hua)中（河南(nan)靈寶）背靠(kao)背輸(shu)電(dian)(dian)(dian)擴建(jian)(jian)工(gong)(gong)程。西(xi)(xi)(xi)北(bei)（青海格爾木）至西(xi)(xi)(xi)藏直流聯網(wang)(wang)(wang)輸(shu)變電(dian)(dian)(dian)工(gong)(gong)程前期(qi)工(gong)(gong)作正在加緊開展。
這(zhe)次核準的西北(bei)至華中(zhong)(zhong)聯網(wang)(wang)工程(cheng)在陜西電(dian)網(wang)(wang)及(ji)西北(bei)電(dian)網(wang)(wang)中(zhong)(zhong)處于重(zhong)要(yao)位(wei)置，是(shi)西北(bei)送端電(dian)網(wang)(wang)建設的重(zhong)要(yao)通(tong)道。該工程(cheng)由國(guo)家電(dian)網(wang)(wang)公司直(zhi)接投資，主要(yao)包(bao)括新建寶雞(ji)、德陽換流(liu)站，容(rong)量300萬千瓦；建設寶雞(ji)換流(liu)站至德陽換流(liu)站1回±500千伏直(zhi)流(liu)線路(lu)，線路(lu)長(chang)度約574千米。
工程建成后，將進一步加(jia)強西北與華中電(dian)(dian)網(wang)之間的聯(lian)系(xi)，有(you)利(li)于陜西電(dian)(dian)網(wang)與四川電(dian)(dian)網(wang)之間的相互備用和事故支援(yuan)，并促進能源資源在更大范(fan)圍內優(you)化配置，對于推(tui)動西部經(jing)濟社會全面(mian)發展將發揮重要(yao)作用。
目前，西北電網(wang)有限公(gong)司正在加快750千(qian)伏電網(wang)配(pei)(pei)套工(gong)程(cheng)建設(she)和陜西寶雞(ji)換流站的前期建設(she)準備，積極做好相(xiang)關(guan)配(pei)(pei)合工(gong)作，力爭該直(zhi)流聯網(wang)工(gong)程(cheng)早日(ri)開(kai)工(gong)建設(she)。
