11月23日，由河南送變電建設(she)(she)公司參與建設(she)(she)的(de)鄂豫第四回500千伏聯(lian)絡線一次送電成功，正(zheng)式投運。
鄂豫第(di)四回500千伏聯絡線起于500千伏孝感(gan)變(bian)電站，途經500千伏信(xin)陽(yang)變(bian)電站、駐馬店開關站，止于500千伏邵(shao)陵(ling)變(bian)電站，全(quan)長309千米。該線路共分6個施工標(biao)段，其(qi)中河南送變(bian)電建設(she)公司(si)承建的6標(biao)段在全(quan)線第(di)一個開工。
鄂豫(yu)第四回500千(qian)(qian)(qian)伏(fu)(fu)聯絡(luo)線(xian)的(de)投(tou)(tou)運，使鄂豫(yu)之間電(dian)(dian)(dian)力(li)(li)交(jiao)換能力(li)(li)由200萬(wan)千(qian)(qian)(qian)瓦(wa)(wa)提(ti)(ti)高(gao)至(zhi)280萬(wan)千(qian)(qian)(qian)瓦(wa)(wa)，豫(yu)中至(zhi)豫(yu)南(nan)(nan)斷(duan)面南(nan)(nan)送(song)電(dian)(dian)(dian)力(li)(li)由220萬(wan)千(qian)(qian)(qian)瓦(wa)(wa)提(ti)(ti)高(gao)至(zhi)250萬(wan)千(qian)(qian)(qian)瓦(wa)(wa)，豫(yu)西北外送(song)電(dian)(dian)(dian)力(li)(li)由320萬(wan)千(qian)(qian)(qian)瓦(wa)(wa)提(ti)(ti)高(gao)至(zhi)330萬(wan)千(qian)(qian)(qian)瓦(wa)(wa)，為河南(nan)(nan)電(dian)(dian)(dian)網(wang)，特別是(shi)缺(que)電(dian)(dian)(dian)的(de)開封和商丘地(di)區吸納三(san)峽電(dian)(dian)(dian)力(li)(li)提(ti)(ti)供了必(bi)要(yao)的(de)物質基(ji)礎。同時，還將(jiang)提(ti)(ti)高(gao)河南(nan)(nan)電(dian)(dian)(dian)網(wang)的(de)電(dian)(dian)(dian)力(li)(li)外送(song)能力(li)(li)，進一步鞏(gong)固和加強河南(nan)(nan)全(quan)國(guo)(guo)重要(yao)火電(dian)(dian)(dian)基(ji)地(di)的(de)地(di)位和作用。鄂豫(yu)第四回500千(qian)(qian)(qian)伏(fu)(fu)聯絡(luo)線(xian)的(de)投(tou)(tou)運，對提(ti)(ti)高(gao)全(quan)國(guo)(guo)聯網(wang)及河南(nan)(nan)電(dian)(dian)(dian)網(wang)的(de)穩(wen)定性、可靠性，形(xing)成(cheng)湖北至(zhi)河南(nan)(nan)堅強的(de)500千(qian)(qian)(qian)伏(fu)(fu)電(dian)(dian)(dian)網(wang)網(wang)架(jia)，實現湖北、河南(nan)(nan)電(dian)(dian)(dian)網(wang)相(xiang)互支撐(cheng)，滿(man)足全(quan)國(guo)(guo)聯網(wang)“南(nan)(nan)北互供”具有重要(yao)意義。
據了解，該工(gong)程于(yu)3月(yue)8日開工(gong)，11月(yue)9日完(wan)成竣工(gong)驗(yan)收。從驗(yan)收情況看，該工(gong)程質量良好，基本(ben)做到零(ling)缺陷移(yi)交。施(shi)工(gong)期(qi)間(jian)，駐馬店等地(di)遭(zao)遇50年來最大(da)的(de)洪澇災害，部(bu)分地(di)段洪水泛濫，齊(qi)腰深的(de)水到處都(dou)是，在此情況下，參與(yu)工(gong)程施(shi)工(gong)的(de)河南送變電建設公(gong)司等單位(wei)，采(cai)取各種得(de)力措施(shi)，克服(fu)困難(nan)，確保工(gong)程按期(qi)竣工(gong)。
