2月20日23時25分，隨著220千伏玉屏至(zhi)凱(kai)里(li)雙回輸電(dian)線路(lu)的(de)搶險修復完成(cheng)(cheng)，貴(gui)州(zhou)銅仁、凱(kai)里(li)、都(dou)勻三地區電(dian)網(wang)(wang)并網(wang)(wang)成(cheng)(cheng)功，貴(gui)州(zhou)電(dian)網(wang)(wang)恢復向電(dian)氣(qi)化鐵路(lu)牽(qian)引變電(dian)站(zhan)正常(chang)供(gong)電(dian)，貴(gui)州(zhou)境(jing)內的(de)電(dian)氣(qi)化鐵路(lu)全(quan)部開通。至(zhi)此，南方電(dian)網(wang)(wang)供(gong)電(dian)區域內受災的(de)廣東(dong)、廣西、云南、貴(gui)州(zhou)四省區電(dian)氣(qi)化鐵路(lu)全(quan)部恢復正常(chang)供(gong)電(dian)。
貴州境內共有(you)39座電(dian)(dian)氣(qi)化(hua)鐵路(lu)牽引變(bian)電(dian)(dian)站，向(xiang)貴州境內的湘黔、川(chuan)黔、貴昆、南昆、渝懷共5條電(dian)(dian)氣(qi)化(hua)鐵路(lu)提(ti)供牽引電(dian)(dian)力(li)。此次(ci)罕(han)見(jian)的凝凍(dong)災害，使貴州東部(bu)和(he)南部(bu)的銅仁、凱里、都(dou)勻3地電(dian)(dian)網與(yu)主網解(jie)列，由于獨立運(yun)行后(hou)裝機容量有(you)限，承受不(bu)(bu)了電(dian)(dian)氣(qi)化(hua)鐵路(lu)運(yun)行時、特別是頻繁啟動時產生的沖擊負荷(he)，大龍(long)電(dian)(dian)廠(chang)、凱里電(dian)(dian)廠(chang)雖(sui)多(duo)次(ci)帶(dai)(dai)本地負荷(he)運(yun)行，但不(bu)(bu)斷(duan)出現停機、電(dian)(dian)網供電(dian)(dian)全停的狀況。所(suo)以，雖(sui)然貴州東部(bu)的11座電(dian)(dian)氣(qi)化(hua)鐵牽引變(bian)電(dian)(dian)站大多(duo)帶(dai)(dai)電(dian)(dian)，但僅可解(jie)決照(zhao)明電(dian)(dian)力(li)，仍不(bu)(bu)具備向(xiang)鐵路(lu)機車(che)牽引變(bian)電(dian)(dian)站供電(dian)(dian)的條件(jian)。
經(jing)過(guo)貴(gui)州(zhou)電(dian)(dian)網公司(si)的(de)(de)(de)連日(ri)搶修，220千伏凱玉雙回輸(shu)電(dian)(dian)線(xian)路(lu)倒塔斷線(xian)處全部(bu)(bu)(bu)(bu)(bu)處理完成，貴(gui)州(zhou)東部(bu)(bu)(bu)(bu)(bu)和南部(bu)(bu)(bu)(bu)(bu)8臺(tai)機(ji)組（130萬(wan)千瓦）開始聯網運(yun)(yun)行(xing)，已經(jing)具(ju)備了滿(man)足電(dian)(dian)氣(qi)(qi)化鐵(tie)牽引用電(dian)(dian)需要的(de)(de)(de)能力，可以(yi)保證在電(dian)(dian)力機(ji)車牽引運(yun)(yun)行(xing)時(shi)，鐵(tie)路(lu)機(ji)車運(yun)(yun)行(xing)的(de)(de)(de)穩定，以(yi)及電(dian)(dian)網和發(fa)電(dian)(dian)機(ji)組運(yun)(yun)行(xing)的(de)(de)(de)穩定。從2月21日(ri)起，貴(gui)州(zhou)東部(bu)(bu)(bu)(bu)(bu)、南部(bu)(bu)(bu)(bu)(bu)的(de)(de)(de)電(dian)(dian)氣(qi)(qi)化鐵(tie)路(lu)和大部(bu)(bu)(bu)(bu)(bu)分企業，具(ju)備了開工生產(chan)的(de)(de)(de)條(tiao)件。此前廣東、廣西、云南電(dian)(dian)氣(qi)(qi)化鐵(tie)路(lu)牽引變電(dian)(dian)站都已恢(hui)復了供電(dian)(dian)正(zheng)常。
南方電(dian)網公司將繼續舉全網之力加(jia)快搶修復電(dian)進度，確保實(shi)現3月底前恢復電(dian)網正常運(yun)行的(de)目標，為(wei)四省(sheng)區經濟(ji)社會發(fa)展(zhan)提供更加(jia)穩(wen)定(ding)可(ke)靠(kao)的(de)電(dian)力供應。
