2月19日(ri)，浙(zhe)江北春、天曉兩(liang)條500千伏輸電線(xian)路經過22晝夜的艱苦(ku)搶修(xiu)，于當晚21時11分正式投入運行。這兩(liang)條線(xian)路的恢復(fu)(fu)投運，使(shi)浙(zhe)江寧波電網(wang)(wang)500千伏網(wang)(wang)架結構恢復(fu)(fu)正常，電網(wang)(wang)穩定性得到進一步提高。
這兩條線路的(de)受損電塔海拔(ba)超過(guo)500米(mi)，位于(yu)(yu)寧(ning)波北侖地區的(de)一個常年風(feng)力很大的(de)山口，在搶(qiang)修施工(gong)(gong)過(guo)程中，連續多(duo)天遭遇7-11級大風(feng)，每班(ban)電力搶(qiang)修施工(gong)(gong)工(gong)(gong)人只能在塔上工(gong)(gong)作半小時，國家電網公司(si)(si)的(de)浙(zhe)江(jiang)送(song)變電公司(si)(si)現場施工(gong)(gong)人員(yuan)克服(fu)了重(zhong)重(zhong)困難，在加強安(an)全措施的(de)前(qian)提下，多(duo)班(ban)次輪流(liu)上塔搶(qiang)修，終于(yu)(yu)在正(zheng)月十五大負荷來臨之前(qian)，將線路搶(qiang)通投(tou)運。
該線路的恢(hui)(hui)復(fu)投運，使失(shi)去達22日(ri)之久的浙江春曉變(bian)(bian)恢(hui)(hui)復(fu)500千(qian)(qian)伏(fu)聯絡，寧(ning)波(bo)電(dian)網(wang)500千(qian)(qian)伏(fu)網(wang)架結構恢(hui)(hui)復(fu)正(zheng)常(chang)，電(dian)網(wang)穩定性得到進一(yi)步提(ti)高(gao)(gao)。春曉變(bian)(bian)供(gong)(gong)區供(gong)(gong)電(dian)能(neng)力提(ti)高(gao)(gao)60萬(wan)(wan)千(qian)(qian)瓦(wa)(wa)(wa)(wa)，目前(qian)已限電(dian)20萬(wan)(wan)千(qian)(qian)瓦(wa)(wa)(wa)(wa)全(quan)部解(jie)放。寧(ning)波(bo)電(dian)網(wang)供(gong)(gong)電(dian)能(neng)力提(ti)高(gao)(gao)100萬(wan)(wan)千(qian)(qian)瓦(wa)(wa)(wa)(wa)以上，其中(zhong)天一(yi)主變(bian)(bian)下送(song)(song)限額由125萬(wan)(wan)千(qian)(qian)瓦(wa)(wa)(wa)(wa)提(ti)高(gao)(gao)到180萬(wan)(wan)千(qian)(qian)瓦(wa)(wa)(wa)(wa)，春曉變(bian)(bian)下送(song)(song)限額提(ti)高(gao)(gao)到60萬(wan)(wan)千(qian)(qian)瓦(wa)(wa)(wa)(wa)。北(bei)侖電(dian)廠電(dian)力送(song)(song)出能(neng)力增(zeng)加(jia)50萬(wan)(wan)千(qian)(qian)瓦(wa)(wa)(wa)(wa)，除滿足寧(ning)波(bo)地區供(gong)(gong)電(dian)外，還可支援全(quan)省(sheng)發用電(dian)平衡。
目(mu)前，國家(jia)電(dian)(dian)網營業區域內，停(ting)(ting)運變電(dian)(dian)站已(yi)(yi)恢(hui)(hui)(hui)復(fu)(fu)813座，停(ting)(ting)運輸電(dian)(dian)線路已(yi)(yi)恢(hui)(hui)(hui)復(fu)(fu)14531條，損毀桿塔(ta)已(yi)(yi)恢(hui)(hui)(hui)復(fu)(fu)165838基(ji)，恢(hui)(hui)(hui)復(fu)(fu)率全部(bu)超過(guo)90%。國家(jia)電(dian)(dian)網公司已(yi)(yi)累(lei)計恢(hui)(hui)(hui)復(fu)(fu)停(ting)(ting)電(dian)(dian)用(yong)(yong)戶(hu)(hu)2609萬戶(hu)(hu)，占累(lei)計停(ting)(ting)電(dian)(dian)用(yong)(yong)戶(hu)(hu)的96.44%，其中城市停(ting)(ting)電(dian)(dian)用(yong)(yong)戶(hu)(hu)已(yi)(yi)恢(hui)(hui)(hui)復(fu)(fu)595.24萬戶(hu)(hu)，恢(hui)(hui)(hui)復(fu)(fu)率達到99.96%，已(yi)(yi)逼近完(wan)勝。
