11月23日，由河南送變電(dian)建設公司(si)參與建設的(de)鄂豫第(di)四回500千伏聯絡(luo)線一(yi)次(ci)送電(dian)成功，正式投運。
鄂豫第四回500千(qian)伏(fu)聯(lian)絡(luo)線起于(yu)500千(qian)伏(fu)孝(xiao)感變電站，途經(jing)500千(qian)伏(fu)信陽變電站、駐馬店(dian)開關站，止于(yu)500千(qian)伏(fu)邵陵變電站，全(quan)長309千(qian)米(mi)。該線路共分6個(ge)(ge)施工標段(duan)，其中河南送變電建設公司承建的6標段(duan)在全(quan)線第一個(ge)(ge)開工。
鄂(e)(e)豫(yu)第四回(hui)500千(qian)(qian)伏聯絡(luo)線的(de)(de)投運，使(shi)鄂(e)(e)豫(yu)之(zhi)間電(dian)(dian)(dian)(dian)力交換能(neng)力由200萬千(qian)(qian)瓦(wa)提(ti)高(gao)至280萬千(qian)(qian)瓦(wa)，豫(yu)中至豫(yu)南(nan)(nan)斷面南(nan)(nan)送電(dian)(dian)(dian)(dian)力由220萬千(qian)(qian)瓦(wa)提(ti)高(gao)至250萬千(qian)(qian)瓦(wa)，豫(yu)西北外(wai)送電(dian)(dian)(dian)(dian)力由320萬千(qian)(qian)瓦(wa)提(ti)高(gao)至330萬千(qian)(qian)瓦(wa)，為河(he)南(nan)(nan)電(dian)(dian)(dian)(dian)網(wang)(wang)，特別是缺電(dian)(dian)(dian)(dian)的(de)(de)開封(feng)和(he)商丘地區吸(xi)納(na)三峽(xia)電(dian)(dian)(dian)(dian)力提(ti)供(gong)了必要的(de)(de)物質基礎。同時，還(huan)將提(ti)高(gao)河(he)南(nan)(nan)電(dian)(dian)(dian)(dian)網(wang)(wang)的(de)(de)電(dian)(dian)(dian)(dian)力外(wai)送能(neng)力，進一(yi)步(bu)鞏固和(he)加(jia)強(qiang)河(he)南(nan)(nan)全(quan)國(guo)重要火電(dian)(dian)(dian)(dian)基地的(de)(de)地位和(he)作用。鄂(e)(e)豫(yu)第四回(hui)500千(qian)(qian)伏聯絡(luo)線的(de)(de)投運，對提(ti)高(gao)全(quan)國(guo)聯網(wang)(wang)及河(he)南(nan)(nan)電(dian)(dian)(dian)(dian)網(wang)(wang)的(de)(de)穩定性、可靠性，形成湖(hu)北至河(he)南(nan)(nan)堅強(qiang)的(de)(de)500千(qian)(qian)伏電(dian)(dian)(dian)(dian)網(wang)(wang)網(wang)(wang)架，實(shi)現(xian)湖(hu)北、河(he)南(nan)(nan)電(dian)(dian)(dian)(dian)網(wang)(wang)相互支撐(cheng)，滿足全(quan)國(guo)聯網(wang)(wang)“南(nan)(nan)北互供(gong)”具(ju)有重要意(yi)義。
據了解，該工(gong)程(cheng)(cheng)于3月8日開(kai)工(gong)，11月9日完成(cheng)竣工(gong)驗(yan)收。從驗(yan)收情況看，該工(gong)程(cheng)(cheng)質量良(liang)好，基(ji)本做到(dao)零缺陷移交(jiao)。施工(gong)期(qi)(qi)間，駐馬店等地遭遇(yu)50年來最大的洪澇(lao)災害，部(bu)分地段(duan)洪水泛濫，齊腰深的水到(dao)處都是，在此情況下(xia)，參與工(gong)程(cheng)(cheng)施工(gong)的河南送變(bian)電建(jian)設公司(si)等單位，采取各種得力措(cuo)施，克服困難，確保工(gong)程(cheng)(cheng)按期(qi)(qi)竣工(gong)。
