6月(yue)18日，寧(ning)夏自治區發改委牽(qian)頭(tou)組(zu)成驗(yan)收(shou)組(zu)，一致(zhi)通過2013-2014年寧(ning)夏農網改造升級工程(cheng)整體驗(yan)收(shou)。
國網(wang)(wang)寧夏(xia)(xia)電(dian)(dian)(dian)力(li)投(tou)資10億元實施2013-2014年寧夏(xia)(xia)農網(wang)(wang)改(gai)造升(sheng)(sheng)級(ji)工(gong)程。截至(zhi)5月底，該公(gong)司新(xin)建、改(gai)造35千(qian)(qian)(qian)(qian)伏(fu)(fu)變電(dian)(dian)(dian)站(zhan)11座，增容5.04萬(wan)千(qian)(qian)(qian)(qian)伏(fu)(fu)安，其中9座變電(dian)(dian)(dian)站(zhan)實現(xian)雙電(dian)(dian)(dian)源供(gong)電(dian)(dian)(dian)，8座變電(dian)(dian)(dian)站(zhan)實現(xian)雙主變供(gong)電(dian)(dian)(dian)；新(xin)建及(ji)改(gai)造35千(qian)(qian)(qian)(qian)伏(fu)(fu)線(xian)路224.52千(qian)(qian)(qian)(qian)米、10千(qian)(qian)(qian)(qian)伏(fu)(fu)線(xian)路3073.06千(qian)(qian)(qian)(qian)米、低壓線(xian)路3397.54千(qian)(qian)(qian)(qian)米；接進(jin)戶(hu)線(xian)1358.54千(qian)(qian)(qian)(qian)米；新(xin)建及(ji)更換10千(qian)(qian)(qian)(qian)伏(fu)(fu)配電(dian)(dian)(dian)變壓器1893臺，戶(hu)表改(gai)造6.82萬(wan)戶(hu)。通過(guo)改(gai)造升(sheng)(sheng)級(ji)，寧夏(xia)(xia)農村(cun)(cun)電(dian)(dian)(dian)網(wang)(wang)網(wang)(wang)架結(jie)構和供(gong)電(dian)(dian)(dian)能(neng)力(li)得(de)到(dao)進(jin)一步(bu)增強，電(dian)(dian)(dian)網(wang)(wang)運(yun)行方式(shi)更加靈活，供(gong)電(dian)(dian)(dian)可(ke)靠性大幅提升(sheng)(sheng)，為寧夏(xia)(xia)農村(cun)(cun)經濟提速和產業(ye)結(jie)構調整打下良好基礎。
在(zai)工(gong)程(cheng)實施過(guo)程(cheng)中，國網(wang)(wang)寧夏電(dian)力按照(zhao)“五(wu)(wu)制(zhi)”管理和(he)工(gong)程(cheng)質量責任制(zhi)要求，發揮“三集五(wu)(wu)大”體(ti)系(xi)優勢，突(tu)出各層(ceng)級(ji)責任落實，建(jian)立發展、建(jian)設、運檢、營(ying)銷(xiao)、物(wu)資等多(duo)部門協同管控機制(zhi)，每(mei)周通報工(gong)程(cheng)進(jin)展、存在(zai)問題和(he)解決措施，全面加大工(gong)程(cheng)管控力度(du)。該公司結合(he)自治區空間發展戰略規劃和(he)美麗鄉村(cun)建(jian)設，積極推廣農網(wang)(wang)新技(ji)術、新產品、新材(cai)料、新工(gong)藝(yi)，應用農網(wang)(wang)典型(xing)供電(dian)模式(shi)，實施全網(wang)(wang)無(wu)功(gong)(gong)(gong)優化和(he)功(gong)(gong)(gong)率(lv)因數自動補(bu)償等，新建(jian)及改造(zao)的35千伏變電(dian)站主變全部為有(you)載調壓(ya)變壓(ya)器，配備無(wu)功(gong)(gong)(gong)補(bu)償裝置(zhi)，并(bing)利用“四遙”功(gong)(gong)(gong)能實現遠程(cheng)有(you)載調壓(ya)和(he)無(wu)功(gong)(gong)(gong)補(bu)償裝置(zhi)投切(qie)操作。
國(guo)網寧(ning)夏電力堅(jian)持“改一(yi)(yi)條線(xian)成一(yi)(yi)條線(xian)，改一(yi)(yi)個(ge)臺(tai)區(qu)成一(yi)(yi)個(ge)臺(tai)區(qu)”的建設原則，同步(bu)改造升級(ji)(ji)饋線(xian)覆蓋(gai)區(qu)域的分支及臺(tai)區(qu)低(di)壓線(xian)路。升級(ji)(ji)后(hou)的供(gong)電設施均達(da)到(dao)或超過(guo)(guo)了國(guo)家(jia)《農網改造升級(ji)(ji)工(gong)程技術(shu)原則》標準，避(bi)免了重復(fu)建設和重復(fu)停電。該(gai)公司(si)加(jia)強過(guo)(guo)程管控，全(quan)方(fang)位(wei)(wei)、全(quan)過(guo)(guo)程監(jian)(jian)理工(gong)程實(shi)施情況，并對關鍵工(gong)序、部位(wei)(wei)、階段實(shi)施旁站(zhan)監(jian)(jian)理；每周(zhou)通報所屬各單位(wei)(wei)工(gong)程投資完成率(lv)、項目完工(gong)率(lv)、驗收(shou)率(lv)、結算率(lv)、決(jue)算率(lv)、審計率(lv)、資料(liao)歸檔率(lv)，確保(bao)工(gong)程安全(quan)質量。
改造升(sheng)級后(hou)，寧夏農(nong)(nong)網年度故(gu)障跳閘次數減(jian)少12%，農(nong)(nong)村用(yong)(yong)電量由24.32億千(qian)瓦時增加到(dao)32.24億千(qian)瓦時，農(nong)(nong)網10千(qian)伏線損(sun)率(lv)下降(jiang)了(le)(le)2.64個(ge)百分點，低(di)壓線損(sun)率(lv)下降(jiang)了(le)(le)2.78個(ge)百分點；供電可靠率(lv)提升(sheng)至99.937%，居民端(duan)電壓合格率(lv)提升(sheng)至97.831%。同時，寧夏農(nong)(nong)村電網科技支撐能力得(de)到(dao)進一(yi)步(bu)提升(sheng)，實現故(gu)障快(kuai)速(su)定位，縮短故(gu)障搶修時間，農(nong)(nong)村客戶(hu)(hu)由“一(yi)表一(yi)戶(hu)(hu)”向智(zhi)能電表全(quan)覆蓋(gai)、全(quan)采集、全(quan)應(ying)用(yong)(yong)轉變。
