2月20日23時25分，隨(sui)著220千伏玉屏至(zhi)凱(kai)里雙回輸電(dian)(dian)線路的搶險修復完成，貴州(zhou)銅(tong)仁、凱(kai)里、都(dou)勻三地區電(dian)(dian)網并(bing)網成功，貴州(zhou)電(dian)(dian)網恢復向電(dian)(dian)氣(qi)化(hua)(hua)鐵(tie)路牽引變電(dian)(dian)站正(zheng)常供(gong)電(dian)(dian)，貴州(zhou)境內(nei)的電(dian)(dian)氣(qi)化(hua)(hua)鐵(tie)路全部開通。至(zhi)此，南方電(dian)(dian)網供(gong)電(dian)(dian)區域內(nei)受災的廣(guang)東、廣(guang)西、云南、貴州(zhou)四省區電(dian)(dian)氣(qi)化(hua)(hua)鐵(tie)路全部恢復正(zheng)常供(gong)電(dian)(dian)。
貴(gui)州境(jing)內共有39座(zuo)電(dian)(dian)(dian)(dian)氣(qi)化(hua)鐵(tie)路(lu)牽(qian)引變電(dian)(dian)(dian)(dian)站(zhan)，向(xiang)(xiang)貴(gui)州境(jing)內的(de)湘黔(qian)、川(chuan)黔(qian)、貴(gui)昆(kun)、南昆(kun)、渝懷(huai)共5條電(dian)(dian)(dian)(dian)氣(qi)化(hua)鐵(tie)路(lu)提供(gong)牽(qian)引電(dian)(dian)(dian)(dian)力。此次罕見的(de)凝凍(dong)災害，使貴(gui)州東部和南部的(de)銅仁(ren)、凱(kai)里、都勻3地電(dian)(dian)(dian)(dian)網(wang)與主(zhu)網(wang)解列，由于獨立(li)運行(xing)后裝機容量有限，承受不了(le)電(dian)(dian)(dian)(dian)氣(qi)化(hua)鐵(tie)路(lu)運行(xing)時(shi)、特別是頻繁(fan)啟動時(shi)產生的(de)沖(chong)擊負(fu)(fu)荷，大龍電(dian)(dian)(dian)(dian)廠、凱(kai)里電(dian)(dian)(dian)(dian)廠雖多次帶(dai)本(ben)地負(fu)(fu)荷運行(xing)，但不斷(duan)出現停(ting)機、電(dian)(dian)(dian)(dian)網(wang)供(gong)電(dian)(dian)(dian)(dian)全停(ting)的(de)狀況。所以，雖然(ran)貴(gui)州東部的(de)11座(zuo)電(dian)(dian)(dian)(dian)氣(qi)化(hua)鐵(tie)牽(qian)引變電(dian)(dian)(dian)(dian)站(zhan)大多帶(dai)電(dian)(dian)(dian)(dian)，但僅(jin)可解決照明電(dian)(dian)(dian)(dian)力，仍不具備向(xiang)(xiang)鐵(tie)路(lu)機車牽(qian)引變電(dian)(dian)(dian)(dian)站(zhan)供(gong)電(dian)(dian)(dian)(dian)的(de)條件(jian)。
經過貴州電(dian)網(wang)公司(si)的(de)連日搶(qiang)修，220千伏凱玉雙回輸電(dian)線路倒塔斷線處(chu)全部(bu)處(chu)理(li)完成(cheng)，貴州東(dong)部(bu)和南(nan)部(bu)8臺機(ji)組（130萬千瓦）開始(shi)聯網(wang)運(yun)行(xing)，已經具(ju)(ju)備(bei)了(le)滿足電(dian)氣(qi)化(hua)鐵牽(qian)引用電(dian)需要(yao)的(de)能力(li)，可以(yi)保證在(zai)電(dian)力(li)機(ji)車牽(qian)引運(yun)行(xing)時，鐵路機(ji)車運(yun)行(xing)的(de)穩(wen)定，以(yi)及電(dian)網(wang)和發(fa)電(dian)機(ji)組運(yun)行(xing)的(de)穩(wen)定。從2月(yue)21日起，貴州東(dong)部(bu)、南(nan)部(bu)的(de)電(dian)氣(qi)化(hua)鐵路和大部(bu)分企業(ye)，具(ju)(ju)備(bei)了(le)開工(gong)生(sheng)產的(de)條件。此前(qian)廣(guang)東(dong)、廣(guang)西、云(yun)南(nan)電(dian)氣(qi)化(hua)鐵路牽(qian)引變電(dian)站都(dou)已恢(hui)復(fu)了(le)供電(dian)正常(chang)。
南方電(dian)網公司將繼續舉全網之力加快(kuai)搶修復電(dian)進度，確保實(shi)現(xian)3月底前(qian)恢(hui)復電(dian)網正常(chang)運行的目標，為四省區經(jing)濟社(she)會發(fa)展(zhan)提供(gong)更加穩定可靠的電(dian)力供(gong)應。
