2月20日23時(shi)25分，隨著(zhu)220千伏玉屏至(zhi)凱里(li)雙回輸(shu)電(dian)(dian)線路(lu)的搶險修復(fu)完成，貴州(zhou)(zhou)銅(tong)仁、凱里(li)、都勻三地區(qu)電(dian)(dian)網(wang)并網(wang)成功，貴州(zhou)(zhou)電(dian)(dian)網(wang)恢復(fu)向(xiang)電(dian)(dian)氣化鐵(tie)路(lu)牽(qian)引變(bian)電(dian)(dian)站正(zheng)(zheng)常供(gong)電(dian)(dian)，貴州(zhou)(zhou)境內的電(dian)(dian)氣化鐵(tie)路(lu)全部(bu)開通。至(zhi)此，南方電(dian)(dian)網(wang)供(gong)電(dian)(dian)區(qu)域內受(shou)災的廣東、廣西、云南、貴州(zhou)(zhou)四省(sheng)區(qu)電(dian)(dian)氣化鐵(tie)路(lu)全部(bu)恢復(fu)正(zheng)(zheng)常供(gong)電(dian)(dian)。
貴州境內共有39座電(dian)(dian)(dian)氣化(hua)鐵(tie)路牽引(yin)變電(dian)(dian)(dian)站(zhan)(zhan)，向貴州境內的(de)湘(xiang)黔(qian)、川(chuan)黔(qian)、貴昆、南昆、渝(yu)懷共5條電(dian)(dian)(dian)氣化(hua)鐵(tie)路提供(gong)牽引(yin)電(dian)(dian)(dian)力。此次罕見(jian)的(de)凝凍災(zai)害，使(shi)貴州東部和南部的(de)銅(tong)仁、凱(kai)里(li)、都勻(yun)3地電(dian)(dian)(dian)網與主網解(jie)(jie)列，由于(yu)獨立運行后裝機(ji)容量(liang)有限，承(cheng)受不了電(dian)(dian)(dian)氣化(hua)鐵(tie)路運行時、特別是頻繁(fan)啟動(dong)時產(chan)生的(de)沖(chong)擊負荷，大(da)(da)龍電(dian)(dian)(dian)廠、凱(kai)里(li)電(dian)(dian)(dian)廠雖(sui)多次帶本地負荷運行，但(dan)不斷出現停機(ji)、電(dian)(dian)(dian)網供(gong)電(dian)(dian)(dian)全停的(de)狀況(kuang)。所以，雖(sui)然貴州東部的(de)11座電(dian)(dian)(dian)氣化(hua)鐵(tie)牽引(yin)變電(dian)(dian)(dian)站(zhan)(zhan)大(da)(da)多帶電(dian)(dian)(dian)，但(dan)僅可(ke)解(jie)(jie)決照明電(dian)(dian)(dian)力，仍不具備向鐵(tie)路機(ji)車牽引(yin)變電(dian)(dian)(dian)站(zhan)(zhan)供(gong)電(dian)(dian)(dian)的(de)條件。
經(jing)過(guo)貴州電(dian)(dian)網公司的(de)連日搶修(xiu)，220千伏凱玉雙(shuang)回輸電(dian)(dian)線(xian)路倒塔斷(duan)線(xian)處全部處理完成，貴州東部和南部8臺機組（130萬千瓦）開始聯網運行，已經(jing)具備(bei)了滿足電(dian)(dian)氣化鐵牽(qian)引(yin)用電(dian)(dian)需要的(de)能力，可(ke)以保證在電(dian)(dian)力機車牽(qian)引(yin)運行時(shi)，鐵路機車運行的(de)穩(wen)定(ding)，以及(ji)電(dian)(dian)網和發電(dian)(dian)機組運行的(de)穩(wen)定(ding)。從2月21日起，貴州東部、南部的(de)電(dian)(dian)氣化鐵路和大部分企業(ye)，具備(bei)了開工生產的(de)條(tiao)件。此前廣(guang)東、廣(guang)西、云(yun)南電(dian)(dian)氣化鐵路牽(qian)引(yin)變電(dian)(dian)站都已恢(hui)復了供電(dian)(dian)正常。
南方電(dian)(dian)(dian)網公(gong)司將繼續舉全網之力加快搶修(xiu)復電(dian)(dian)(dian)進(jin)度，確保(bao)實(shi)現(xian)3月(yue)底前恢(hui)復電(dian)(dian)(dian)網正常(chang)運行的目標，為四省區經濟社會(hui)發展提供(gong)更加穩定(ding)可靠的電(dian)(dian)(dian)力供(gong)應。
