11月23日，由(you)河南(nan)送變(bian)電(dian)(dian)建設(she)公(gong)司參與(yu)建設(she)的鄂豫第四回(hui)500千伏聯絡線一次(ci)送電(dian)(dian)成(cheng)功，正式投運。
鄂豫第四回500千(qian)伏(fu)(fu)聯絡(luo)線(xian)(xian)起于500千(qian)伏(fu)(fu)孝(xiao)感(gan)變(bian)(bian)電站，途經(jing)500千(qian)伏(fu)(fu)信陽變(bian)(bian)電站、駐馬店開關站，止于500千(qian)伏(fu)(fu)邵陵變(bian)(bian)電站，全(quan)長309千(qian)米。該線(xian)(xian)路(lu)共分6個施(shi)工(gong)(gong)標(biao)(biao)段，其中河南送(song)變(bian)(bian)電建設公(gong)司承建的(de)6標(biao)(biao)段在(zai)全(quan)線(xian)(xian)第一個開工(gong)(gong)。
鄂(e)(e)豫(yu)第四(si)回(hui)500千(qian)伏聯(lian)絡線(xian)的投運(yun)(yun)，使鄂(e)(e)豫(yu)之間(jian)電(dian)(dian)(dian)(dian)(dian)力(li)交換能(neng)力(li)由200萬千(qian)瓦(wa)(wa)提(ti)高(gao)至280萬千(qian)瓦(wa)(wa)，豫(yu)中至豫(yu)南(nan)斷面南(nan)送電(dian)(dian)(dian)(dian)(dian)力(li)由220萬千(qian)瓦(wa)(wa)提(ti)高(gao)至250萬千(qian)瓦(wa)(wa)，豫(yu)西北(bei)外送電(dian)(dian)(dian)(dian)(dian)力(li)由320萬千(qian)瓦(wa)(wa)提(ti)高(gao)至330萬千(qian)瓦(wa)(wa)，為河(he)南(nan)電(dian)(dian)(dian)(dian)(dian)網，特別是(shi)缺電(dian)(dian)(dian)(dian)(dian)的開封(feng)和(he)商丘地區吸(xi)納(na)三峽(xia)電(dian)(dian)(dian)(dian)(dian)力(li)提(ti)供(gong)了必要的物質基礎(chu)。同(tong)時，還將提(ti)高(gao)河(he)南(nan)電(dian)(dian)(dian)(dian)(dian)網的電(dian)(dian)(dian)(dian)(dian)力(li)外送能(neng)力(li)，進一步鞏固和(he)加強河(he)南(nan)全國重(zhong)(zhong)要火電(dian)(dian)(dian)(dian)(dian)基地的地位和(he)作用。鄂(e)(e)豫(yu)第四(si)回(hui)500千(qian)伏聯(lian)絡線(xian)的投運(yun)(yun)，對提(ti)高(gao)全國聯(lian)網及河(he)南(nan)電(dian)(dian)(dian)(dian)(dian)網的穩定性(xing)、可靠性(xing)，形成湖北(bei)至河(he)南(nan)堅強的500千(qian)伏電(dian)(dian)(dian)(dian)(dian)網網架，實現湖北(bei)、河(he)南(nan)電(dian)(dian)(dian)(dian)(dian)網相互(hu)支(zhi)撐(cheng)，滿足全國聯(lian)網“南(nan)北(bei)互(hu)供(gong)”具有重(zhong)(zhong)要意(yi)義。
據(ju)了解，該工(gong)程(cheng)于3月8日開工(gong)，11月9日完(wan)成竣(jun)工(gong)驗(yan)收。從驗(yan)收情況看，該工(gong)程(cheng)質(zhi)量良好，基本做到零缺陷移(yi)交。施工(gong)期(qi)間(jian)，駐馬店(dian)等地遭遇(yu)50年(nian)來最大的洪澇災害，部分地段洪水(shui)泛濫，齊腰深(shen)的水(shui)到處都是，在此(ci)情況下(xia)，參與工(gong)程(cheng)施工(gong)的河(he)南送變電建設公司等單位，采取各(ge)種得力(li)措施，克服(fu)困(kun)難，確保工(gong)程(cheng)按期(qi)竣(jun)工(gong)。
