6月18日，寧夏自(zi)治區(qu)發改(gai)(gai)委牽頭組(zu)成(cheng)驗收組(zu)，一致通過2013-2014年寧夏農網改(gai)(gai)造升級工程整體驗收。
國網寧夏(xia)電(dian)(dian)力(li)投資(zi)10億(yi)元實(shi)施2013-2014年寧夏(xia)農網改造(zao)升級工程。截至5月底(di)，該公司新(xin)建(jian)(jian)、改造(zao)35千伏(fu)(fu)(fu)變(bian)(bian)電(dian)(dian)站(zhan)11座，增容5.04萬(wan)千伏(fu)(fu)(fu)安，其中9座變(bian)(bian)電(dian)(dian)站(zhan)實(shi)現雙電(dian)(dian)源供(gong)電(dian)(dian)，8座變(bian)(bian)電(dian)(dian)站(zhan)實(shi)現雙主(zhu)變(bian)(bian)供(gong)電(dian)(dian)；新(xin)建(jian)(jian)及(ji)改造(zao)35千伏(fu)(fu)(fu)線(xian)路(lu)224.52千米(mi)、10千伏(fu)(fu)(fu)線(xian)路(lu)3073.06千米(mi)、低壓線(xian)路(lu)3397.54千米(mi)；接(jie)進戶(hu)線(xian)1358.54千米(mi)；新(xin)建(jian)(jian)及(ji)更換10千伏(fu)(fu)(fu)配電(dian)(dian)變(bian)(bian)壓器1893臺，戶(hu)表改造(zao)6.82萬(wan)戶(hu)。通過(guo)改造(zao)升級，寧夏(xia)農村(cun)(cun)電(dian)(dian)網網架結構(gou)和供(gong)電(dian)(dian)能力(li)得到進一步增強，電(dian)(dian)網運行方式(shi)更加靈活(huo)，供(gong)電(dian)(dian)可靠性大幅提升，為寧夏(xia)農村(cun)(cun)經濟提速和產業結構(gou)調整(zheng)打下良好基礎。
在工(gong)(gong)(gong)程(cheng)實施過程(cheng)中(zhong)，國網(wang)寧夏電(dian)(dian)力按照“五制”管理和(he)工(gong)(gong)(gong)程(cheng)質(zhi)量責(ze)任(ren)制要求，發揮“三集五大”體系優勢(shi)，突出各層級責(ze)任(ren)落實，建(jian)立(li)發展(zhan)(zhan)、建(jian)設、運檢(jian)、營銷、物資等(deng)多部門協同管控(kong)(kong)機(ji)制，每周通(tong)報(bao)工(gong)(gong)(gong)程(cheng)進展(zhan)(zhan)、存(cun)在問題和(he)解(jie)決(jue)措施，全(quan)(quan)面加大工(gong)(gong)(gong)程(cheng)管控(kong)(kong)力度。該(gai)公(gong)司(si)結(jie)合自(zi)治(zhi)區空間發展(zhan)(zhan)戰(zhan)略規(gui)劃和(he)美(mei)麗鄉村建(jian)設，積極推廣農網(wang)新技術、新產品、新材料、新工(gong)(gong)(gong)藝，應用農網(wang)典型供電(dian)(dian)模式，實施全(quan)(quan)網(wang)無功(gong)優化和(he)功(gong)率因數自(zi)動補(bu)償等(deng)，新建(jian)及改(gai)造的(de)35千伏變電(dian)(dian)站主變全(quan)(quan)部為有載(zai)調(diao)壓(ya)變壓(ya)器，配(pei)備(bei)無功(gong)補(bu)償裝置，并利用“四遙”功(gong)能實現遠程(cheng)有載(zai)調(diao)壓(ya)和(he)無功(gong)補(bu)償裝置投切(qie)操作。
國網寧夏電力堅持“改(gai)一條線(xian)(xian)成一條線(xian)(xian)，改(gai)一個(ge)(ge)臺區(qu)成一個(ge)(ge)臺區(qu)”的(de)建設原(yuan)(yuan)則，同步(bu)改(gai)造升級饋線(xian)(xian)覆(fu)蓋區(qu)域(yu)的(de)分支及臺區(qu)低(di)壓線(xian)(xian)路。升級后的(de)供(gong)電設施均達到或超過了國家《農網改(gai)造升級工(gong)(gong)程技術原(yuan)(yuan)則》標準，避免了重復(fu)建設和重復(fu)停(ting)電。該公司加(jia)強(qiang)過程管控，全(quan)方位(wei)、全(quan)過程監理工(gong)(gong)程實(shi)(shi)施情況，并對(dui)關鍵工(gong)(gong)序(xu)、部位(wei)、階段實(shi)(shi)施旁站監理；每周通報(bao)所屬(shu)各單位(wei)工(gong)(gong)程投資完成率(lv)(lv)、項目完工(gong)(gong)率(lv)(lv)、驗收率(lv)(lv)、結(jie)算率(lv)(lv)、決(jue)算率(lv)(lv)、審計率(lv)(lv)、資料歸(gui)檔率(lv)(lv)，確保工(gong)(gong)程安全(quan)質量。
改造升級后，寧(ning)夏農(nong)(nong)網(wang)年度故障(zhang)跳閘(zha)次數減(jian)少12%，農(nong)(nong)村(cun)用(yong)電(dian)(dian)量由24.32億千瓦時(shi)增加到(dao)32.24億千瓦時(shi)，農(nong)(nong)網(wang)10千伏線損(sun)率(lv)下降了(le)2.64個百(bai)分(fen)點，低壓線損(sun)率(lv)下降了(le)2.78個百(bai)分(fen)點；供電(dian)(dian)可(ke)靠(kao)率(lv)提(ti)升至99.937%，居(ju)民(min)端電(dian)(dian)壓合格率(lv)提(ti)升至97.831%。同時(shi)，寧(ning)夏農(nong)(nong)村(cun)電(dian)(dian)網(wang)科技(ji)支(zhi)撐能力得到(dao)進一步提(ti)升，實現(xian)故障(zhang)快(kuai)速定位，縮短故障(zhang)搶修時(shi)間，農(nong)(nong)村(cun)客戶由“一表(biao)一戶”向智能電(dian)(dian)表(biao)全(quan)覆蓋、全(quan)采集、全(quan)應(ying)用(yong)轉變(bian)。
