　　2月20日23時25分(fen)，隨著220千伏(fu)玉屏至凱里雙回輸電(dian)(dian)(dian)線路的搶險修復完成(cheng)，貴州銅(tong)仁(ren)、凱里、都勻(yun)三地區(qu)電(dian)(dian)(dian)網并(bing)網成(cheng)功，貴州電(dian)(dian)(dian)網恢復向電(dian)(dian)(dian)氣化(hua)鐵(tie)路牽引變電(dian)(dian)(dian)站正常(chang)供(gong)(gong)電(dian)(dian)(dian)，貴州境內(nei)的電(dian)(dian)(dian)氣化(hua)鐵(tie)路全部開通。至此，南方電(dian)(dian)(dian)網供(gong)(gong)電(dian)(dian)(dian)區(qu)域內(nei)受災的廣東、廣西、云(yun)南、貴州四省區(qu)電(dian)(dian)(dian)氣化(hua)鐵(tie)路全部恢復正常(chang)供(gong)(gong)電(dian)(dian)(dian)。

　　貴州境(jing)(jing)內共有39座電氣(qi)化鐵(tie)路(lu)牽(qian)引變(bian)(bian)電站(zhan)(zhan)，向貴州境(jing)(jing)內的(de)湘黔、川黔、貴昆、南(nan)昆、渝懷(huai)共5條電氣(qi)化鐵(tie)路(lu)提供牽(qian)引電力。此次(ci)罕見的(de)凝凍災害(hai)，使(shi)貴州東(dong)部和南(nan)部的(de)銅(tong)仁、凱里、都(dou)勻3地(di)電網與主網解列(lie)，由(you)于獨(du)立運行后裝機容量(liang)有限(xian)，承受不(bu)了電氣(qi)化鐵(tie)路(lu)運行時(shi)、特別是(shi)頻繁啟動時(shi)產(chan)生的(de)沖擊(ji)負(fu)荷(he)，大(da)(da)龍電廠、凱里電廠雖多(duo)次(ci)帶本地(di)負(fu)荷(he)運行，但不(bu)斷出現停(ting)機、電網供電全停(ting)的(de)狀況。所以，雖然貴州東(dong)部的(de)11座電氣(qi)化鐵(tie)牽(qian)引變(bian)(bian)電站(zhan)(zhan)大(da)(da)多(duo)帶電，但僅可解決照明電力，仍不(bu)具備(bei)向鐵(tie)路(lu)機車牽(qian)引變(bian)(bian)電站(zhan)(zhan)供電的(de)條件。

　　經過貴州電(dian)(dian)網(wang)公司的連(lian)日搶(qiang)修，220千伏凱玉雙回(hui)輸電(dian)(dian)線(xian)路(lu)(lu)倒(dao)塔斷(duan)線(xian)處全部(bu)(bu)處理完成，貴州東(dong)(dong)部(bu)(bu)和(he)南部(bu)(bu)8臺機(ji)組（130萬千瓦(wa)）開始聯網(wang)運行(xing)(xing)，已(yi)經具備(bei)了(le)(le)滿(man)足電(dian)(dian)氣(qi)化鐵牽引用電(dian)(dian)需要的能力，可以保證在電(dian)(dian)力機(ji)車牽引運行(xing)(xing)時(shi)，鐵路(lu)(lu)機(ji)車運行(xing)(xing)的穩定(ding)，以及(ji)電(dian)(dian)網(wang)和(he)發(fa)電(dian)(dian)機(ji)組運行(xing)(xing)的穩定(ding)。從2月21日起(qi)，貴州東(dong)(dong)部(bu)(bu)、南部(bu)(bu)的電(dian)(dian)氣(qi)化鐵路(lu)(lu)和(he)大部(bu)(bu)分企(qi)業，具備(bei)了(le)(le)開工生產的條件。此前廣東(dong)(dong)、廣西、云南電(dian)(dian)氣(qi)化鐵路(lu)(lu)牽引變電(dian)(dian)站都已(yi)恢復(fu)了(le)(le)供(gong)電(dian)(dian)正常。

　　南(nan)方(fang)電(dian)網(wang)公(gong)司將繼(ji)續舉全網(wang)之力加(jia)快(kuai)搶修復電(dian)進度(du)，確保(bao)實現3月(yue)底(di)前恢復電(dian)網(wang)正常運行(xing)的(de)目標，為(wei)四省區經濟社(she)會發展提供更加(jia)穩定(ding)可靠(kao)的(de)電(dian)力供應。
