5月(yue)12日，榆橫(heng)(heng)(heng)-濰(wei)坊1000千伏特(te)(te)高(gao)壓交流(liu)輸變電(dian)工(gong)程(cheng)（以下簡(jian)稱“榆橫(heng)(heng)(heng)—濰(wei)坊工(gong)程(cheng)”）開工(gong)動員大(da)會(hui)在京召開。榆橫(heng)(heng)(heng)-濰(wei)坊工(gong)程(cheng)是國家大(da)氣污染防治行動計劃“四交四直”特(te)(te)高(gao)壓工(gong)程(cheng)中(zhong)第5條獲得核(he)準開工(gong)的(de)輸電(dian)通道(dao)，是華北特(te)(te)高(gao)壓交直流(liu)主網架的(de)重(zhong)要組成(cheng)部(bu)分，將促進(jin)陜西(xi)與(yu)山西(xi)能(neng)源(yuan)基地(di)開發與(yu)外(wai)送，有效(xiao)緩解中(zhong)東部(bu)電(dian)力緊張(zhang)局面。
黨中央(yang)、國(guo)務院領導高(gao)度重視特(te)高(gao)壓(ya)發(fa)展，多次做(zuo)出重要指(zhi)示，提出明確要求。去年，國(guo)家將“四交四直”特(te)高(gao)壓(ya)工(gong)(gong)程(cheng)納入(ru)大氣污(wu)染防治(zhi)行(xing)動(dong)計劃。榆(yu)橫—濰坊工(gong)(gong)程(cheng)的(de)開(kai)工(gong)(gong)，標(biao)志著(zhu)列入(ru)國(guo)家大氣污(wu)染防治(zhi)行(xing)動(dong)計劃的(de)四條(tiao)特(te)高(gao)壓(ya)交流工(gong)(gong)程(cheng)已經全部開(kai)工(gong)(gong)，也標(biao)志著(zhu)特(te)高(gao)壓(ya)電網進(jin)入(ru)全面提速、大規模(mo)建設(she)的(de)新階段(duan)。
榆橫(heng)-濰(wei)(wei)坊(fang)工(gong)程(cheng)途經陜西(xi)、山西(xi)、河北省、山東4省，新建(jian)晉中、石家(jia)莊、濰(wei)(wei)坊(fang)3座變電(dian)站和榆橫(heng)開關站，變電(dian)容(rong)量(liang)1500萬(wan)千伏安(an)，擴建(jian)濟南變電(dian)站出線(xian)間隔，全線(xian)雙回路架設，全長2×1048.5千米(mi)。工(gong)程(cheng)投資241.8億(yi)元，于2015年5月獲(huo)得(de)國(guo)家(jia)發(fa)改委核(he)準，計劃于2017年建(jian)成投運。榆橫(heng)—濰(wei)(wei)坊(fang)工(gong)程(cheng)是(shi)迄今為止(zhi)輸電(dian)距離最(zui)長的特高(gao)壓(ya)交流工(gong)程(cheng)，工(gong)程(cheng)將首(shou)次采用解體運輸變壓(ya)器，降低(di)大件運輸風險，減少工(gong)程(cheng)費(fei)用。工(gong)程(cheng)還將全面采用我國(guo)自主(zhu)開發(fa)的特高(gao)壓(ya)交流輸電(dian)技術和裝備(bei)(bei)。榆橫(heng)—濰(wei)(wei)坊(fang)工(gong)程(cheng)對于促(cu)進陜西(xi)與山西(xi)能源基(ji)地開發(fa)，加快(kuai)資源優勢向經濟優勢轉化，拉(la)動內需和經濟增長，帶動裝備(bei)(bei)制造業轉型升(sheng)級，提高(gao)華北地區電(dian)網(wang)承載(zai)能力，落(luo)實國(guo)家(jia)大氣(qi)污(wu)染(ran)防(fang)治行動計劃，改善大氣(qi)環境質量(liang)等均(jun)具(ju)有十(shi)分重要的意義。
