經過湖(hu)南(nan)(nan)省(sheng)電力公司電網(wang)建(jian)(jian)設運行(xing)分公司、湖(hu)南(nan)(nan)省(sheng)電網(wang)建(jian)(jian)設公司、湖(hu)南(nan)(nan)省(sheng)電力設計院等參建(jian)(jian)單位一(yi)年(nian)多的共同努力，2009年(nian)12月(yue)28日，湖(hu)南(nan)(nan)省(sheng)首座(zuo)“兩型(xing)一(yi)化”500千(qian)伏永州南(nan)(nan)（紫霞）變電站(zhan)建(jian)(jian)成投運，標(biao)志著湖(hu)南(nan)(nan)500千(qian)伏“三橫”“兩縱”“兩環網(wang)”主網(wang)架基(ji)本形成。
500千(qian)伏(fu)永州(zhou)南變電站(zhan)位(wei)于永州(zhou)市(shi)寧(ning)遠縣舜陵(ling)鎮(zhen)紫霞街，本(ben)期建設規模為一臺75萬千(qian)伏(fu)安主變壓器，配套建設500千(qian)伏(fu)線(xian)路2回、221千(qian)米，220千(qian)伏(fu)線(xian)路5回、80千(qian)米，輸變電工(gong)程共計投資近10億元。工(gong)程于2008年10月(yue)底開工(gong)，2009年4月(yue)開始基(ji)礎施工(gong)，12月(yue)28日正式(shi)投運。
該變(bian)電(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)的投運，大(da)大(da)加強(qiang)了湘南電(dian)(dian)(dian)(dian)(dian)網結構(gou)和永(yong)州(zhou)(zhou)南部電(dian)(dian)(dian)(dian)(dian)網供電(dian)(dian)(dian)(dian)(dian)能力，解決了永(yong)州(zhou)(zhou)電(dian)(dian)(dian)(dian)(dian)力供應瓶頸(jing)問題；改寫(xie)了永(yong)州(zhou)(zhou)電(dian)(dian)(dian)(dian)(dian)網通過2條(tiao)220千(qian)伏(fu)線路供帶(dai)4座220千(qian)伏(fu)變(bian)電(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)的歷史，對永(yong)州(zhou)(zhou)電(dian)(dian)(dian)(dian)(dian)網的穩定(ding)起著(zhu)重要(yao)作用；有利于(yu)西部電(dian)(dian)(dian)(dian)(dian)力在永(yong)州(zhou)(zhou)電(dian)(dian)(dian)(dian)(dian)網的消納(na)并轉(zhuan)送(song)至郴州(zhou)(zhou)電(dian)(dian)(dian)(dian)(dian)網。該工程是(shi)湖南公司標(biao)準化建設(she)示范項目(mu)，也是(shi)湖南公司2009年(nian)電(dian)(dian)(dian)(dian)(dian)網建設(she)的收官之作。據悉，截至2009年(nian)12月底，湖南超(chao)高壓電(dian)(dian)(dian)(dian)(dian)網投運500千(qian)伏(fu)變(bian)電(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)15座、開(kai)關站(zhan)(zhan)1座，投運輸電(dian)(dian)(dian)(dian)(dian)線路40條(tiao)4326千(qian)米(mi)。
該變電(dian)站(zhan)作為湖(hu)南(nan)省首座資源節(jie)約型、環境(jing)友好(hao)型、工(gong)(gong)業(ye)化(hua)的(de)500千(qian)伏變電(dian)站(zhan)，按照“三通一(yi)標”原則建(jian)設(she)。變電(dian)站(zhan)內各(ge)設(she)備區除了(le)由混凝土路面(mian)相連，其余所有空地覆蓋著拇指(zhi)大小的(de)白(bai)色碎石(shi)，不再種植花草，這樣可減(jian)少(shao)后(hou)期維護、節(jie)約水資源。此外，變電(dian)站(zhan)內的(de)建(jian)筑數量(liang)顯著減(jian)少(shao)，主(zhu)控(kong)樓(lou)只有兩層，裝修(xiu)簡單。室內設(she)計理念是從(cong)少(shao)人值守到(dao)無人值守過渡(du)，體現了(le)“工(gong)(gong)業(ye)化(hua)”建(jian)筑的(de)特點。據(ju)悉，僅變電(dian)站(zhan)主(zhu)控(kong)樓(lou)的(de)建(jian)筑面(mian)積就比舊(jiu)式主(zhu)控(kong)樓(lou)減(jian)少(shao)50%。該變電(dian)站(zhan)顯著降(jiang)低了(le)工(gong)(gong)程(cheng)成本，方便了(le)運(yun)行維護，節(jie)約了(le)土地和(he)水資源。
