　　2月20日23時25分，隨著220千伏玉屏(ping)至(zhi)凱(kai)里(li)雙回輸電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線路(lu)(lu)的搶(qiang)險修(xiu)復(fu)完成(cheng)，貴(gui)(gui)州(zhou)銅仁、凱(kai)里(li)、都(dou)勻三地(di)區(qu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)網并網成(cheng)功，貴(gui)(gui)州(zhou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)網恢復(fu)向電(dian)(dian)(dian)(dian)(dian)(dian)(dian)氣化(hua)鐵路(lu)(lu)牽(qian)引(yin)變電(dian)(dian)(dian)(dian)(dian)(dian)(dian)站正常供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，貴(gui)(gui)州(zhou)境內(nei)的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)氣化(hua)鐵路(lu)(lu)全(quan)部開通(tong)。至(zhi)此，南方電(dian)(dian)(dian)(dian)(dian)(dian)(dian)網供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)區(qu)域內(nei)受災的廣東(dong)、廣西、云(yun)南、貴(gui)(gui)州(zhou)四省區(qu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)氣化(hua)鐵路(lu)(lu)全(quan)部恢復(fu)正常供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。

　　貴州(zhou)境內(nei)共有(you)39座電(dian)(dian)(dian)(dian)(dian)氣(qi)(qi)(qi)(qi)化(hua)鐵路(lu)牽(qian)(qian)引(yin)(yin)變(bian)(bian)電(dian)(dian)(dian)(dian)(dian)站(zhan)，向貴州(zhou)境內(nei)的(de)湘黔(qian)、川黔(qian)、貴昆(kun)、南昆(kun)、渝(yu)懷共5條電(dian)(dian)(dian)(dian)(dian)氣(qi)(qi)(qi)(qi)化(hua)鐵路(lu)提供牽(qian)(qian)引(yin)(yin)電(dian)(dian)(dian)(dian)(dian)力。此次罕見的(de)凝凍災害，使貴州(zhou)東(dong)部和(he)南部的(de)銅仁、凱(kai)里、都勻3地(di)電(dian)(dian)(dian)(dian)(dian)網(wang)與主網(wang)解列，由于獨立(li)運行后裝機容量有(you)限，承受不了電(dian)(dian)(dian)(dian)(dian)氣(qi)(qi)(qi)(qi)化(hua)鐵路(lu)運行時(shi)、特(te)別是(shi)頻繁啟動(dong)時(shi)產生的(de)沖擊負荷，大(da)龍電(dian)(dian)(dian)(dian)(dian)廠、凱(kai)里電(dian)(dian)(dian)(dian)(dian)廠雖(sui)多次帶本地(di)負荷運行，但(dan)不斷出現(xian)停機、電(dian)(dian)(dian)(dian)(dian)網(wang)供電(dian)(dian)(dian)(dian)(dian)全停的(de)狀況。所以，雖(sui)然貴州(zhou)東(dong)部的(de)11座電(dian)(dian)(dian)(dian)(dian)氣(qi)(qi)(qi)(qi)化(hua)鐵牽(qian)(qian)引(yin)(yin)變(bian)(bian)電(dian)(dian)(dian)(dian)(dian)站(zhan)大(da)多帶電(dian)(dian)(dian)(dian)(dian)，但(dan)僅可解決(jue)照明電(dian)(dian)(dian)(dian)(dian)力，仍不具備向鐵路(lu)機車牽(qian)(qian)引(yin)(yin)變(bian)(bian)電(dian)(dian)(dian)(dian)(dian)站(zhan)供電(dian)(dian)(dian)(dian)(dian)的(de)條件。

　　經過貴州(zhou)電網(wang)(wang)公司的(de)(de)連日搶(qiang)修(xiu)，220千(qian)伏(fu)凱玉雙回輸電線(xian)路(lu)倒(dao)塔斷線(xian)處(chu)全(quan)部(bu)(bu)處(chu)理完(wan)成，貴州(zhou)東部(bu)(bu)和(he)南部(bu)(bu)8臺機組(zu)（130萬千(qian)瓦）開始聯網(wang)(wang)運(yun)(yun)(yun)行，已(yi)經具備(bei)了滿足(zu)電氣化鐵(tie)(tie)牽引用電需要(yao)的(de)(de)能力(li)，可以保證在電力(li)機車牽引運(yun)(yun)(yun)行時，鐵(tie)(tie)路(lu)機車運(yun)(yun)(yun)行的(de)(de)穩(wen)(wen)定，以及(ji)電網(wang)(wang)和(he)發電機組(zu)運(yun)(yun)(yun)行的(de)(de)穩(wen)(wen)定。從(cong)2月21日起，貴州(zhou)東部(bu)(bu)、南部(bu)(bu)的(de)(de)電氣化鐵(tie)(tie)路(lu)和(he)大部(bu)(bu)分企業，具備(bei)了開工生產的(de)(de)條件。此前廣東、廣西、云南電氣化鐵(tie)(tie)路(lu)牽引變電站(zhan)都(dou)已(yi)恢復了供電正(zheng)常。

　　南方電(dian)網公司將(jiang)繼續舉全網之力加快(kuai)搶修復電(dian)進度，確保實現(xian)3月底前恢復電(dian)網正常運行的目標，為四省區經濟社會發展提供(gong)(gong)更加穩定可(ke)靠的電(dian)力供(gong)(gong)應。
