1月18日(ri)，遼寧(ning)(ning)省“十(shi)二五”農(nong)(nong)(nong)村(cun)電(dian)網(wang)(wang)規(gui)劃(hua)評(ping)審會結束，至此，遼寧(ning)(ning)省電(dian)力有(you)限(xian)公司(si)14個市級供電(dian)企業全部完成(cheng)了農(nong)(nong)(nong)網(wang)(wang)“十(shi)二五”規(gui)劃(hua)編(bian)制工作。國家電(dian)網(wang)(wang)遼寧(ning)(ning)公司(si)組織專家對沈陽、大連、鞍山等(deng)14個地市的“十(shi)二五”農(nong)(nong)(nong)網(wang)(wang)規(gui)劃(hua)進行(xing)了評(ping)審。
據(ju)了解，各地(di)市供(gong)電企(qi)業(ye)的規劃設(she)計從調查和分析現狀(zhuang)入手，分析區(qu)域(yu)內負荷增長趨勢，立足(zu)于(yu)解決現有農(nong)村電網(wang)薄(bo)弱環節，優化農(nong)網(wang)結構，提高農(nong)網(wang)供(gong)電能力和適應性。根據(ju)規劃，“十二五”期間，遼寧公司將(jiang)完善電力負荷集中地(di)區(qu)農(nong)網(wang)，加快建設(she)沿海地(di)區(qu)農(nong)網(wang)，改造設(she)備老(lao)舊(jiu)農(nong)網(wang)。
目前，遼(liao)寧農(nong)(nong)網(wang)(wang)(wang)電(dian)(dian)(dian)力負荷(he)(he)主要集(ji)中(zhong)在沈陽、大連、遼(liao)陽、朝陽、鞍山、營口、錦州，這7個地區農(nong)(nong)網(wang)(wang)(wang)的用電(dian)(dian)(dian)量達186億千(qian)(qian)瓦時，接近整個農(nong)(nong)網(wang)(wang)(wang)負荷(he)(he)的70%。然而(er)，上述電(dian)(dian)(dian)力負荷(he)(he)集(ji)中(zhong)地區的農(nong)(nong)網(wang)(wang)(wang)普遍存在著線(xian)路(lu)滿(man)負荷(he)(he)運行的情況。以沈陽農(nong)(nong)網(wang)(wang)(wang)為(wei)例，現有66千(qian)(qian)伏線(xian)路(lu)93條，其中(zhong)12條干(gan)線(xian)接近滿(man)載運行狀態。“十二五”期間，沈陽市(shi)農(nong)(nong)村(cun)電(dian)(dian)(dian)網(wang)(wang)(wang)規劃建(jian)設66千(qian)(qian)伏項(xiang)目14個，預計到2015年年底，沈陽農(nong)(nong)網(wang)(wang)(wang)將有66千(qian)(qian)伏變(bian)電(dian)(dian)(dian)站(zhan)101座，變(bian)電(dian)(dian)(dian)容量323萬(wan)千(qian)(qian)伏安，66千(qian)(qian)伏線(xian)路(lu)143條，總長1286.7千(qian)(qian)米(mi)。
近年(nian)來，遼寧(ning)沿海地區(qu)、大(da)(da)城市郊區(qu)（縣）招商引(yin)資力(li)度不(bu)斷加大(da)(da)，工業企業開(kai)始向這些地區(qu)轉移(yi)。然而(er)，由于(yu)缺少電(dian)(dian)源點(dian)，一次變(bian)容量不(bu)足，供電(dian)(dian)能力(li)不(bu)足問題日(ri)益突出。位于(yu)遼東灣的營口市就(jiu)面臨著(zhu)這種尷尬(ga)局面。營口農網承擔著(zhu)為老邊區(qu)、蓋州(zhou)市、大(da)(da)石橋(qiao)市共45個(ge)鎮(zhen)區(qu)供電(dian)(dian)的任務，但大(da)(da)部分變(bian)電(dian)(dian)站容量小，主變(bian)年(nian)均負(fu)載率達52%，負(fu)荷(he)高峰時最高負(fu)載率達113%左右。針對(dui)這種情況，“十二(er)五(wu)”期(qi)間，營口地區(qu)農網規劃投(tou)資建設66千(qian)伏(fu)(fu)項目36個(ge)，新增(zeng)變(bian)電(dian)(dian)容量62.3萬千(qian)伏(fu)(fu)安，新建66千(qian)伏(fu)(fu)線路(lu)106.75千(qian)米。
阜(fu)新(xin)市位于遼寧西北部，素有“煤電(dian)(dian)之(zhi)城”之(zhi)稱(cheng)。目前，阜(fu)新(xin)農(nong)網(wang)無發電(dian)(dian)電(dian)(dian)源，農(nong)網(wang)66千伏(fu)(fu)(fu)供(gong)電(dian)(dian)系統主要(yao)以4座220千伏(fu)(fu)(fu)變電(dian)(dian)站作為電(dian)(dian)源點。尤為突出(chu)的是，農(nong)網(wang)設(she)備老(lao)舊，受資金限制，部分線(xian)路為瓷擔線(xian)路，且運行多年(nian)，亟(ji)待改(gai)(gai)造。根(gen)據規劃，阜(fu)新(xin)農(nong)網(wang)“十二五”期間將建設(she)66千伏(fu)(fu)(fu)項目29個，以改(gai)(gai)善網(wang)架結構，降低網(wang)損，提(ti)高(gao)供(gong)電(dian)(dian)可(ke)靠性(xing)。
