5月12日，榆橫(heng)-濰坊1000千伏特(te)高(gao)(gao)(gao)壓(ya)交(jiao)流輸變電(dian)工程(cheng)(cheng)（以下簡稱“榆橫(heng)—濰坊工程(cheng)(cheng)”）開(kai)工動員大(da)會在京召開(kai)。榆橫(heng)-濰坊工程(cheng)(cheng)是國(guo)家大(da)氣(qi)污染防(fang)治(zhi)行動計劃“四交(jiao)四直”特(te)高(gao)(gao)(gao)壓(ya)工程(cheng)(cheng)中第5條(tiao)獲得核準開(kai)工的輸電(dian)通(tong)道，是華北特(te)高(gao)(gao)(gao)壓(ya)交(jiao)直流主網架(jia)的重(zhong)要組成部分，將促進陜西與山西能(neng)源(yuan)基(ji)地開(kai)發與外送，有效(xiao)緩解中東部電(dian)力緊張局面。
黨中央、國務院領(ling)導高(gao)度(du)重視(shi)特(te)高(gao)壓發展(zhan)，多次做出重要指示，提(ti)出明確(que)要求(qiu)。去年(nian)，國家將“四(si)交四(si)直”特(te)高(gao)壓工程(cheng)(cheng)納入大氣(qi)(qi)污染(ran)防治行動(dong)(dong)計劃。榆(yu)橫—濰(wei)坊工程(cheng)(cheng)的開(kai)工，標志著列入國家大氣(qi)(qi)污染(ran)防治行動(dong)(dong)計劃的四(si)條特(te)高(gao)壓交流工程(cheng)(cheng)已經全(quan)部開(kai)工，也標志著特(te)高(gao)壓電(dian)網進入全(quan)面(mian)提(ti)速、大規模建設(she)的新(xin)階段。
榆(yu)橫(heng)(heng)-濰坊工(gong)程(cheng)(cheng)途(tu)經(jing)(jing)陜(shan)(shan)西(xi)、山西(xi)、河北(bei)省(sheng)、山東4省(sheng)，新(xin)建(jian)(jian)晉中、石家莊、濰坊3座變電(dian)站(zhan)(zhan)和(he)榆(yu)橫(heng)(heng)開關站(zhan)(zhan)，變電(dian)容量1500萬千伏安，擴建(jian)(jian)濟南變電(dian)站(zhan)(zhan)出線間隔(ge)，全線雙回路(lu)架設，全長2×1048.5千米。工(gong)程(cheng)(cheng)投(tou)資(zi)241.8億元(yuan)，于2015年(nian)5月(yue)獲(huo)得國家發改委核準(zhun)，計劃于2017年(nian)建(jian)(jian)成(cheng)投(tou)運。榆(yu)橫(heng)(heng)—濰坊工(gong)程(cheng)(cheng)是迄今為止輸電(dian)距離(li)最長的(de)特高壓(ya)交(jiao)流工(gong)程(cheng)(cheng)，工(gong)程(cheng)(cheng)將(jiang)(jiang)首次(ci)采(cai)(cai)用解體運輸變壓(ya)器，降低(di)大(da)(da)件運輸風(feng)險，減(jian)少工(gong)程(cheng)(cheng)費用。工(gong)程(cheng)(cheng)還將(jiang)(jiang)全面采(cai)(cai)用我國自(zi)主開發的(de)特高壓(ya)交(jiao)流輸電(dian)技術和(he)裝(zhuang)備。榆(yu)橫(heng)(heng)—濰坊工(gong)程(cheng)(cheng)對于促進陜(shan)(shan)西(xi)與山西(xi)能源基地開發，加快資(zi)源優勢(shi)向(xiang)經(jing)(jing)濟優勢(shi)轉(zhuan)化，拉(la)動內需和(he)經(jing)(jing)濟增(zeng)長，帶(dai)動裝(zhuang)備制(zhi)造業轉(zhuan)型(xing)升(sheng)級，提(ti)高華北(bei)地區電(dian)網(wang)承載(zai)能力，落實國家大(da)(da)氣污染防(fang)治行動計劃，改善大(da)(da)氣環境質(zhi)量等均具有十(shi)分重要(yao)的(de)意義。
目前，國家電(dian)(dian)(dian)網已(yi)累(lei)計建成(cheng)“三交(jiao)四直(zhi)”特(te)(te)高(gao)壓(ya)工程，在(zai)(zai)(zai)建“四交(jiao)一直(zhi)”特(te)(te)高(gao)壓(ya)工程，在(zai)(zai)(zai)運(yun)在(zai)(zai)(zai)建特(te)(te)高(gao)壓(ya)輸電(dian)(dian)(dian)線路長度超(chao)(chao)過(guo)(guo)1.9萬(wan)公(gong)里，變電(dian)(dian)(dian)（換流）容量(liang)超(chao)(chao)過(guo)(guo)1.9億千伏安（千瓦(wa)），累(lei)計送電(dian)(dian)(dian)超(chao)(chao)過(guo)(guo)3000億千瓦(wa)時(shi)。依托大電(dian)(dian)(dian)網發展新(xin)能(neng)(neng)(neng)源，國家電(dian)(dian)(dian)網新(xin)能(neng)(neng)(neng)源并(bing)網裝機已(yi)突破1.2億千瓦(wa)，成(cheng)為世界風電(dian)(dian)(dian)并(bing)網規(gui)模最大、太陽(yang)能(neng)(neng)(neng)發電(dian)(dian)(dian)增(zeng)(zeng)長最快的電(dian)(dian)(dian)網。特(te)(te)高(gao)壓(ya)在(zai)(zai)(zai)大范圍優化(hua)(hua)能(neng)(neng)(neng)源配置，保障我國能(neng)(neng)(neng)源安全、經濟、清潔、高(gao)效(xiao)發展等(deng)(deng)方面，發揮著日益(yi)重要的作(zuo)用。隨(sui)著后續“五交(jiao)八直(zhi)”特(te)(te)高(gao)壓(ya)工程的加快推進，新(xin)增(zeng)(zeng)特(te)(te)高(gao)壓(ya)電(dian)(dian)(dian)網投(tou)資(zi)(zi)將達到4500億元，加上(shang)各級(ji)電(dian)(dian)(dian)網共投(tou)資(zi)(zi)1.5萬(wan)億元，帶動(dong)電(dian)(dian)(dian)源和相(xiang)關(guan)產業投(tou)資(zi)(zi)1.7萬(wan)億元，可(ke)年均拉動(dong)GDP增(zeng)(zeng)長0.8個百分點以(yi)上(shang)，同(tong)時(shi)還能(neng)(neng)(neng)消化(hua)(hua)鋼鐵、水泥(ni)等(deng)(deng)過(guo)(guo)剩產能(neng)(neng)(neng)，經濟、社會、環境(jing)效(xiao)益(yi)巨大。
