2月20日23時25分，隨(sui)著220千伏玉屏至(zhi)凱里雙回輸電(dian)(dian)線路(lu)的(de)(de)搶險(xian)修復(fu)完成，貴(gui)州(zhou)銅仁、凱里、都勻三地區(qu)電(dian)(dian)網(wang)(wang)并網(wang)(wang)成功，貴(gui)州(zhou)電(dian)(dian)網(wang)(wang)恢(hui)復(fu)向電(dian)(dian)氣(qi)化(hua)(hua)鐵(tie)路(lu)牽引變電(dian)(dian)站正常供電(dian)(dian)，貴(gui)州(zhou)境(jing)內的(de)(de)電(dian)(dian)氣(qi)化(hua)(hua)鐵(tie)路(lu)全(quan)部(bu)開通。至(zhi)此，南方電(dian)(dian)網(wang)(wang)供電(dian)(dian)區(qu)域內受災的(de)(de)廣東(dong)、廣西、云南、貴(gui)州(zhou)四省區(qu)電(dian)(dian)氣(qi)化(hua)(hua)鐵(tie)路(lu)全(quan)部(bu)恢(hui)復(fu)正常供電(dian)(dian)。
貴州境內(nei)(nei)共有39座(zuo)電(dian)(dian)(dian)(dian)氣化鐵路牽(qian)(qian)引(yin)變電(dian)(dian)(dian)(dian)站(zhan)，向貴州境內(nei)(nei)的湘黔(qian)、川黔(qian)、貴昆、南昆、渝懷共5條(tiao)電(dian)(dian)(dian)(dian)氣化鐵路提供(gong)(gong)牽(qian)(qian)引(yin)電(dian)(dian)(dian)(dian)力。此(ci)次罕見的凝凍災(zai)害，使貴州東(dong)(dong)部和南部的銅仁、凱(kai)里、都勻3地(di)電(dian)(dian)(dian)(dian)網(wang)與(yu)主網(wang)解列，由于獨立(li)運(yun)行(xing)后(hou)裝機容量有限，承受不(bu)了電(dian)(dian)(dian)(dian)氣化鐵路運(yun)行(xing)時、特別(bie)是(shi)頻繁啟動時產(chan)生的沖擊負荷，大(da)龍電(dian)(dian)(dian)(dian)廠(chang)、凱(kai)里電(dian)(dian)(dian)(dian)廠(chang)雖(sui)多次帶本地(di)負荷運(yun)行(xing)，但不(bu)斷(duan)出(chu)現停(ting)(ting)機、電(dian)(dian)(dian)(dian)網(wang)供(gong)(gong)電(dian)(dian)(dian)(dian)全停(ting)(ting)的狀況。所(suo)以，雖(sui)然貴州東(dong)(dong)部的11座(zuo)電(dian)(dian)(dian)(dian)氣化鐵牽(qian)(qian)引(yin)變電(dian)(dian)(dian)(dian)站(zhan)大(da)多帶電(dian)(dian)(dian)(dian)，但僅可解決照明電(dian)(dian)(dian)(dian)力，仍不(bu)具備(bei)向鐵路機車牽(qian)(qian)引(yin)變電(dian)(dian)(dian)(dian)站(zhan)供(gong)(gong)電(dian)(dian)(dian)(dian)的條(tiao)件。
經過貴州(zhou)(zhou)電(dian)(dian)(dian)網(wang)公司的(de)連日(ri)搶修(xiu)，220千伏凱玉雙回輸電(dian)(dian)(dian)線路(lu)倒塔斷線處全部(bu)(bu)處理完成(cheng)，貴州(zhou)(zhou)東部(bu)(bu)和(he)南部(bu)(bu)8臺(tai)機組（130萬千瓦）開始聯網(wang)運(yun)行(xing)(xing)，已(yi)經具備了(le)滿足電(dian)(dian)(dian)氣(qi)化(hua)鐵牽引用電(dian)(dian)(dian)需要的(de)能力，可以保證在電(dian)(dian)(dian)力機車牽引運(yun)行(xing)(xing)時，鐵路(lu)機車運(yun)行(xing)(xing)的(de)穩(wen)定，以及電(dian)(dian)(dian)網(wang)和(he)發電(dian)(dian)(dian)機組運(yun)行(xing)(xing)的(de)穩(wen)定。從2月21日(ri)起，貴州(zhou)(zhou)東部(bu)(bu)、南部(bu)(bu)的(de)電(dian)(dian)(dian)氣(qi)化(hua)鐵路(lu)和(he)大部(bu)(bu)分企業，具備了(le)開工生產(chan)的(de)條件。此前廣(guang)東、廣(guang)西、云南電(dian)(dian)(dian)氣(qi)化(hua)鐵路(lu)牽引變電(dian)(dian)(dian)站都已(yi)恢復了(le)供(gong)電(dian)(dian)(dian)正常。
南方電網公司將繼續舉(ju)全網之(zhi)力加快搶(qiang)修復電進度(du)，確保實現3月底(di)前(qian)恢復電網正常運行的目標，為(wei)四(si)省區經濟(ji)社會(hui)發展提供更加穩(wen)定可靠的電力供應。
