2月20日23時(shi)25分，隨著220千伏玉(yu)屏(ping)至凱里(li)(li)雙回輸電(dian)(dian)線路的(de)搶險修復完成，貴州銅仁、凱里(li)(li)、都勻三地區電(dian)(dian)網(wang)(wang)并網(wang)(wang)成功，貴州電(dian)(dian)網(wang)(wang)恢復向電(dian)(dian)氣化鐵(tie)路牽引變(bian)電(dian)(dian)站(zhan)正(zheng)常(chang)供(gong)(gong)電(dian)(dian)，貴州境內的(de)電(dian)(dian)氣化鐵(tie)路全部開通。至此(ci)，南(nan)方電(dian)(dian)網(wang)(wang)供(gong)(gong)電(dian)(dian)區域內受災的(de)廣東、廣西、云南(nan)、貴州四(si)省區電(dian)(dian)氣化鐵(tie)路全部恢復正(zheng)常(chang)供(gong)(gong)電(dian)(dian)。
貴(gui)州(zhou)境(jing)內(nei)共(gong)有(you)39座電(dian)(dian)(dian)氣(qi)(qi)(qi)化(hua)鐵(tie)路牽(qian)引變電(dian)(dian)(dian)站，向貴(gui)州(zhou)境(jing)內(nei)的(de)(de)(de)湘黔、川黔、貴(gui)昆、南昆、渝懷(huai)共(gong)5條(tiao)電(dian)(dian)(dian)氣(qi)(qi)(qi)化(hua)鐵(tie)路提供(gong)牽(qian)引電(dian)(dian)(dian)力。此次罕(han)見的(de)(de)(de)凝(ning)凍災害(hai)，使貴(gui)州(zhou)東(dong)部(bu)和南部(bu)的(de)(de)(de)銅仁、凱里、都(dou)勻3地電(dian)(dian)(dian)網與(yu)主網解列，由于(yu)獨立運行后裝機容量(liang)有(you)限，承(cheng)受不了電(dian)(dian)(dian)氣(qi)(qi)(qi)化(hua)鐵(tie)路運行時、特別是頻(pin)繁啟動(dong)時產生的(de)(de)(de)沖擊負荷，大(da)龍電(dian)(dian)(dian)廠、凱里電(dian)(dian)(dian)廠雖多次帶(dai)本地負荷運行，但不斷出現停機、電(dian)(dian)(dian)網供(gong)電(dian)(dian)(dian)全停的(de)(de)(de)狀況。所以，雖然貴(gui)州(zhou)東(dong)部(bu)的(de)(de)(de)11座電(dian)(dian)(dian)氣(qi)(qi)(qi)化(hua)鐵(tie)牽(qian)引變電(dian)(dian)(dian)站大(da)多帶(dai)電(dian)(dian)(dian)，但僅可解決照明電(dian)(dian)(dian)力，仍不具(ju)備(bei)向鐵(tie)路機車牽(qian)引變電(dian)(dian)(dian)站供(gong)電(dian)(dian)(dian)的(de)(de)(de)條(tiao)件。
經過(guo)貴州(zhou)電(dian)網(wang)公(gong)司的(de)(de)連日(ri)搶修，220千伏凱玉雙回輸電(dian)線路(lu)倒塔斷(duan)線處全部處理完成，貴州(zhou)東部和南(nan)部8臺機組(zu)（130萬(wan)千瓦）開(kai)始聯網(wang)運(yun)行(xing)，已經具備(bei)了(le)滿足電(dian)氣化鐵牽(qian)引(yin)用電(dian)需(xu)要的(de)(de)能力，可以保證在電(dian)力機車牽(qian)引(yin)運(yun)行(xing)時，鐵路(lu)機車運(yun)行(xing)的(de)(de)穩定(ding)，以及電(dian)網(wang)和發(fa)電(dian)機組(zu)運(yun)行(xing)的(de)(de)穩定(ding)。從2月(yue)21日(ri)起(qi)，貴州(zhou)東部、南(nan)部的(de)(de)電(dian)氣化鐵路(lu)和大部分企(qi)業，具備(bei)了(le)開(kai)工生產的(de)(de)條件。此前(qian)廣東、廣西、云(yun)南(nan)電(dian)氣化鐵路(lu)牽(qian)引(yin)變電(dian)站都已恢復(fu)了(le)供(gong)電(dian)正常。
南方電(dian)網公司(si)將繼續舉全網之力加(jia)(jia)快(kuai)搶修(xiu)復(fu)電(dian)進(jin)度，確(que)保實現3月底前恢復(fu)電(dian)網正(zheng)常(chang)運行的目標(biao)，為四(si)省區經濟社會發展提供更加(jia)(jia)穩定可靠的電(dian)力供應。
