2月20日(ri)23時25分，隨著220千伏玉屏至凱里雙回(hui)輸電(dian)(dian)線路(lu)的搶險(xian)修(xiu)復完成(cheng)(cheng)，貴州(zhou)(zhou)(zhou)銅仁、凱里、都勻三地區電(dian)(dian)網并網成(cheng)(cheng)功，貴州(zhou)(zhou)(zhou)電(dian)(dian)網恢(hui)復向電(dian)(dian)氣化鐵路(lu)牽引(yin)變電(dian)(dian)站正(zheng)常供電(dian)(dian)，貴州(zhou)(zhou)(zhou)境內的電(dian)(dian)氣化鐵路(lu)全部開通。至此，南方電(dian)(dian)網供電(dian)(dian)區域(yu)內受(shou)災(zai)的廣東(dong)、廣西、云南、貴州(zhou)(zhou)(zhou)四省區電(dian)(dian)氣化鐵路(lu)全部恢(hui)復正(zheng)常供電(dian)(dian)。
貴(gui)(gui)州(zhou)(zhou)境內共有(you)39座電(dian)(dian)(dian)(dian)氣化(hua)鐵(tie)路牽(qian)(qian)引變(bian)電(dian)(dian)(dian)(dian)站，向(xiang)貴(gui)(gui)州(zhou)(zhou)境內的(de)湘(xiang)黔、川(chuan)黔、貴(gui)(gui)昆(kun)、南昆(kun)、渝懷共5條電(dian)(dian)(dian)(dian)氣化(hua)鐵(tie)路提(ti)供(gong)牽(qian)(qian)引電(dian)(dian)(dian)(dian)力。此次罕見的(de)凝凍災害，使(shi)貴(gui)(gui)州(zhou)(zhou)東部和南部的(de)銅仁、凱里、都勻3地(di)(di)電(dian)(dian)(dian)(dian)網(wang)與主網(wang)解列，由于獨立運行后裝機容(rong)量有(you)限，承受不了電(dian)(dian)(dian)(dian)氣化(hua)鐵(tie)路運行時、特別(bie)是(shi)頻繁(fan)啟動(dong)時產生的(de)沖擊負荷，大(da)龍電(dian)(dian)(dian)(dian)廠、凱里電(dian)(dian)(dian)(dian)廠雖多次帶本地(di)(di)負荷運行，但不斷出現停機、電(dian)(dian)(dian)(dian)網(wang)供(gong)電(dian)(dian)(dian)(dian)全停的(de)狀況。所以，雖然貴(gui)(gui)州(zhou)(zhou)東部的(de)11座電(dian)(dian)(dian)(dian)氣化(hua)鐵(tie)牽(qian)(qian)引變(bian)電(dian)(dian)(dian)(dian)站大(da)多帶電(dian)(dian)(dian)(dian)，但僅(jin)可解決照明(ming)電(dian)(dian)(dian)(dian)力，仍不具備向(xiang)鐵(tie)路機車牽(qian)(qian)引變(bian)電(dian)(dian)(dian)(dian)站供(gong)電(dian)(dian)(dian)(dian)的(de)條件。
經(jing)過(guo)貴州(zhou)(zhou)電(dian)網(wang)公司的(de)連日搶修，220千(qian)伏凱玉(yu)雙(shuang)回輸電(dian)線(xian)路(lu)(lu)倒塔(ta)斷線(xian)處全部(bu)處理完(wan)成，貴州(zhou)(zhou)東部(bu)和(he)南(nan)部(bu)8臺機(ji)組（130萬千(qian)瓦）開始聯網(wang)運(yun)行，已(yi)經(jing)具備(bei)了滿足(zu)電(dian)氣化(hua)鐵(tie)牽引(yin)用電(dian)需要的(de)能力(li)，可(ke)以保證在電(dian)力(li)機(ji)車(che)牽引(yin)運(yun)行時(shi)，鐵(tie)路(lu)(lu)機(ji)車(che)運(yun)行的(de)穩定(ding)，以及電(dian)網(wang)和(he)發電(dian)機(ji)組運(yun)行的(de)穩定(ding)。從(cong)2月21日起，貴州(zhou)(zhou)東部(bu)、南(nan)部(bu)的(de)電(dian)氣化(hua)鐵(tie)路(lu)(lu)和(he)大(da)部(bu)分企業，具備(bei)了開工(gong)生產的(de)條件。此前廣東、廣西、云南(nan)電(dian)氣化(hua)鐵(tie)路(lu)(lu)牽引(yin)變電(dian)站都已(yi)恢復(fu)了供(gong)電(dian)正(zheng)常。
南(nan)方電(dian)(dian)網公司將(jiang)繼續舉(ju)全網之力加(jia)快(kuai)搶修復電(dian)(dian)進度，確保實現3月底前恢復電(dian)(dian)網正常運行的(de)目標，為四省區經濟(ji)社會發展提供更加(jia)穩定(ding)可靠的(de)電(dian)(dian)力供應。
