經過湖(hu)南(nan)省(sheng)電(dian)力公(gong)(gong)司電(dian)網(wang)建(jian)設運行分公(gong)(gong)司、湖(hu)南(nan)省(sheng)電(dian)網(wang)建(jian)設公(gong)(gong)司、湖(hu)南(nan)省(sheng)電(dian)力設計院等參建(jian)單(dan)位一(yi)(yi)年(nian)多的共(gong)同努力，2009年(nian)12月28日，湖(hu)南(nan)省(sheng)首(shou)座“兩型(xing)一(yi)(yi)化”500千伏永(yong)州(zhou)南(nan)（紫霞(xia)）變電(dian)站建(jian)成(cheng)投(tou)運，標志著湖(hu)南(nan)500千伏“三(san)橫(heng)”“兩縱”“兩環網(wang)”主網(wang)架基本形成(cheng)。
500千伏(fu)永(yong)州南變(bian)電(dian)站位于(yu)永(yong)州市寧遠(yuan)縣舜陵鎮(zhen)紫霞街，本期建(jian)設(she)規模(mo)為一臺75萬千伏(fu)安(an)主(zhu)變(bian)壓器(qi)，配套建(jian)設(she)500千伏(fu)線(xian)(xian)路2回、221千米，220千伏(fu)線(xian)(xian)路5回、80千米，輸變(bian)電(dian)工(gong)程共計投資近(jin)10億元。工(gong)程于(yu)2008年10月底開(kai)工(gong)，2009年4月開(kai)始基礎施工(gong)，12月28日正(zheng)式投運。
該變(bian)電(dian)(dian)(dian)站(zhan)的(de)(de)投運(yun)(yun)，大(da)大(da)加(jia)強(qiang)了湘南(nan)電(dian)(dian)(dian)網(wang)(wang)(wang)結構和永(yong)州(zhou)(zhou)南(nan)部電(dian)(dian)(dian)網(wang)(wang)(wang)供(gong)電(dian)(dian)(dian)能力(li)，解決了永(yong)州(zhou)(zhou)電(dian)(dian)(dian)力(li)供(gong)應瓶頸問題；改(gai)寫了永(yong)州(zhou)(zhou)電(dian)(dian)(dian)網(wang)(wang)(wang)通(tong)過2條(tiao)220千(qian)伏線(xian)路供(gong)帶4座220千(qian)伏變(bian)電(dian)(dian)(dian)站(zhan)的(de)(de)歷史，對永(yong)州(zhou)(zhou)電(dian)(dian)(dian)網(wang)(wang)(wang)的(de)(de)穩定起著重要作(zuo)用；有利于西部電(dian)(dian)(dian)力(li)在永(yong)州(zhou)(zhou)電(dian)(dian)(dian)網(wang)(wang)(wang)的(de)(de)消納并(bing)轉送至(zhi)郴州(zhou)(zhou)電(dian)(dian)(dian)網(wang)(wang)(wang)。該工程(cheng)是湖(hu)南(nan)公(gong)司標準(zhun)化建設(she)示范項目(mu)，也是湖(hu)南(nan)公(gong)司2009年電(dian)(dian)(dian)網(wang)(wang)(wang)建設(she)的(de)(de)收官之(zhi)作(zuo)。據悉，截至(zhi)2009年12月底(di)，湖(hu)南(nan)超(chao)高壓電(dian)(dian)(dian)網(wang)(wang)(wang)投運(yun)(yun)500千(qian)伏變(bian)電(dian)(dian)(dian)站(zhan)15座、開關站(zhan)1座，投運(yun)(yun)輸電(dian)(dian)(dian)線(xian)路40條(tiao)4326千(qian)米。
該變(bian)電(dian)(dian)站(zhan)(zhan)作為湖南(nan)省首座資源(yuan)節(jie)約(yue)型(xing)、環境友(you)好(hao)型(xing)、工業化的(de)500千伏(fu)變(bian)電(dian)(dian)站(zhan)(zhan)，按照“三通一標”原則建設(she)。變(bian)電(dian)(dian)站(zhan)(zhan)內各(ge)設(she)備區(qu)除(chu)了(le)由混凝(ning)土路面相連，其余所有(you)空地覆蓋(gai)著(zhu)拇(mu)指大小(xiao)的(de)白色碎石，不再種植花草，這樣(yang)可減(jian)少后期(qi)維護(hu)、節(jie)約(yue)水資源(yuan)。此外，變(bian)電(dian)(dian)站(zhan)(zhan)內的(de)建筑(zhu)數量顯著(zhu)減(jian)少，主控樓只有(you)兩層，裝修簡單。室(shi)內設(she)計(ji)理(li)念(nian)是從少人值守到無(wu)人值守過渡，體現了(le)“工業化”建筑(zhu)的(de)特點。據悉，僅變(bian)電(dian)(dian)站(zhan)(zhan)主控樓的(de)建筑(zhu)面積就比(bi)舊式主控樓減(jian)少50%。該變(bian)電(dian)(dian)站(zhan)(zhan)顯著(zhu)降低了(le)工程成本，方便了(le)運行維護(hu)，節(jie)約(yue)了(le)土地和水資源(yuan)。
