為有效緩解四(si)川(chuan)枯(ku)水(shui)(shui)期電(dian)力(li)供(gong)應緊張和(he)豐水(shui)(shui)期棄水(shui)(shui)損失(shi)問題，支援四(si)川(chuan)災區恢復重(zhong)建(jian)，按照國家電(dian)網(wang)(wang)公司的統一(yi)部署，國家電(dian)網(wang)(wang)直流公司全力(li)加(jia)快西北－華中（四(si)川(chuan)）直流聯網(wang)(wang)工程建(jian)設(she)步伐，力(li)爭2009年底建(jian)成投(tou)運，較原計劃工期提前四(si)個月。
西(xi)北－華中(zhong)（四川）直流聯網(wang)(wang)工(gong)(gong)程(cheng)是國(guo)家跨區電(dian)(dian)(dian)網(wang)(wang)建(jian)(jian)設重點工(gong)(gong)程(cheng)，也是我國(guo)首個實現(xian)100％國(guo)產(chan)化的±500千(qian)伏(fu)輸(shu)電(dian)(dian)(dian)工(gong)(gong)程(cheng)，對于提高我國(guo)輸(shu)變電(dian)(dian)(dian)設備自(zi)主創新和制造能力具有(you)(you)重要意義。工(gong)(gong)程(cheng)起點為(wei)陜西(xi)寶雞(ji)，落點為(wei)四川德陽，計劃(hua)新建(jian)(jian)±500千(qian)伏(fu)換流站(zhan)兩座，直流線路一條，全長約(yue)574公里，途經(jing)四川、甘肅、陜西(xi)3省12個市縣，工(gong)(gong)程(cheng)額(e)定輸(shu)送容量300萬千(qian)瓦，靜態投(tou)資(zi)約(yue)54億元。工(gong)(gong)程(cheng)建(jian)(jian)成(cheng)后，將為(wei)四川災(zai)后重建(jian)(jian)及經(jing)濟(ji)發展提供有(you)(you)力支持(chi)。枯水(shui)(shui)(shui)期(qi)，西(xi)北電(dian)(dian)(dian)網(wang)(wang)向四川電(dian)(dian)(dian)網(wang)(wang)輸(shu)送火電(dian)(dian)(dian)電(dian)(dian)(dian)量，可(ke)(ke)極(ji)大(da)地緩(huan)解四川由于煤(mei)炭(tan)產(chan)量不足(zu)造成(cheng)的缺電(dian)(dian)(dian)問題(ti)，并減輕西(xi)北地區鐵路運輸(shu)壓力；豐水(shui)(shui)(shui)期(qi)，將四川富余水(shui)(shui)(shui)電(dian)(dian)(dian)送至西(xi)北地區，推動(dong)四川資(zi)源優(you)勢轉化為(wei)經(jing)濟(ji)優(you)勢。工(gong)(gong)程(cheng)在實現(xian)水(shui)(shui)(shui)電(dian)(dian)(dian)跨流域(yu)補(bu)償調(diao)節(jie)、水(shui)(shui)(shui)火電(dian)(dian)(dian)互補(bu)調(diao)節(jie)、減少電(dian)(dian)(dian)網(wang)(wang)備用容量，以及有(you)(you)效提高電(dian)(dian)(dian)網(wang)(wang)抵御(yu)自(zi)然災(zai)害能力和可(ke)(ke)靠供電(dian)(dian)(dian)水(shui)(shui)(shui)平等(deng)方面，具有(you)(you)顯著(zhu)的經(jing)濟(ji)效益和社會效益。
國家(jia)電(dian)網直(zhi)流(liu)公司積極(ji)組織(zhi)各(ge)參建(jian)(jian)方力(li)量(liang)，克服施工條件艱苦、余震(zhen)不斷，以及因地震(zhen)造成的(de)建(jian)(jian)筑材料(liao)供(gong)應緊張、價格(ge)上漲等不利因素，在確保安(an)全、質量(liang)前提下，強化(hua)施工管(guan)理，加強設(she)備制造協調，優化(hua)工期計(ji)劃，全面加快工程建(jian)(jian)設(she)進度。
截至3月(yue)7日(ri)，已完成換流站主控樓(lou)建筑(zhu)封頂，交(jiao)(jiao)流場、交(jiao)(jiao)流濾波器場構架吊裝等重要工程節(jie)點，工程建設(she)進(jin)度總體順(shun)利。
