經過湖南(nan)(nan)省電(dian)(dian)力(li)公司(si)電(dian)(dian)網建(jian)(jian)設運行分公司(si)、湖南(nan)(nan)省電(dian)(dian)網建(jian)(jian)設公司(si)、湖南(nan)(nan)省電(dian)(dian)力(li)設計院等參(can)建(jian)(jian)單位一(yi)年多的共同努力(li)，2009年12月28日，湖南(nan)(nan)省首座“兩型(xing)一(yi)化”500千伏(fu)永(yong)州南(nan)(nan)（紫霞）變電(dian)(dian)站建(jian)(jian)成投運，標(biao)志著湖南(nan)(nan)500千伏(fu)“三橫(heng)”“兩縱(zong)”“兩環網”主網架(jia)基本形成。
500千(qian)(qian)伏永州南變電(dian)站位于永州市(shi)寧遠(yuan)縣舜陵鎮紫霞街，本期建設規模為(wei)一臺75萬千(qian)(qian)伏安主變壓(ya)器，配套(tao)建設500千(qian)(qian)伏線路(lu)2回、221千(qian)(qian)米，220千(qian)(qian)伏線路(lu)5回、80千(qian)(qian)米，輸(shu)變電(dian)工程共計(ji)投資(zi)近10億元。工程于2008年10月(yue)底開工，2009年4月(yue)開始基礎施工，12月(yue)28日正(zheng)式投運。
該(gai)變(bian)(bian)電(dian)(dian)(dian)(dian)(dian)站的投運，大(da)大(da)加(jia)強了湘南(nan)(nan)電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)結構和永州(zhou)南(nan)(nan)部電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)供電(dian)(dian)(dian)(dian)(dian)能力(li)，解決了永州(zhou)電(dian)(dian)(dian)(dian)(dian)力(li)供應瓶(ping)頸問題；改寫了永州(zhou)電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)通過2條220千伏線(xian)路(lu)供帶4座(zuo)220千伏變(bian)(bian)電(dian)(dian)(dian)(dian)(dian)站的歷史，對(dui)永州(zhou)電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)的穩定起著重要作用；有利于(yu)西部電(dian)(dian)(dian)(dian)(dian)力(li)在(zai)永州(zhou)電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)的消納并轉送(song)至郴州(zhou)電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)。該(gai)工程是(shi)湖(hu)南(nan)(nan)公司(si)標(biao)準(zhun)化建設示(shi)范項(xiang)目，也(ye)是(shi)湖(hu)南(nan)(nan)公司(si)2009年電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)建設的收官之作。據悉，截至2009年12月底(di)，湖(hu)南(nan)(nan)超高(gao)壓電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)投運500千伏變(bian)(bian)電(dian)(dian)(dian)(dian)(dian)站15座(zuo)、開關(guan)站1座(zuo)，投運輸電(dian)(dian)(dian)(dian)(dian)線(xian)路(lu)40條4326千米。
該變電(dian)(dian)站(zhan)作為湖南省首座資源節約型、環境友好型、工(gong)業化(hua)的(de)500千伏變電(dian)(dian)站(zhan)，按(an)照“三通一(yi)標”原則建(jian)設(she)。變電(dian)(dian)站(zhan)內各設(she)備區(qu)除(chu)了由混凝土路(lu)面(mian)相連，其余(yu)所有空地覆蓋著(zhu)拇(mu)指(zhi)大(da)小的(de)白色(se)碎石，不(bu)再(zai)種植花(hua)草，這樣可減(jian)(jian)少(shao)后期(qi)維(wei)護(hu)、節約水(shui)資源。此外，變電(dian)(dian)站(zhan)內的(de)建(jian)筑數(shu)量顯著(zhu)減(jian)(jian)少(shao)，主控(kong)樓只(zhi)有兩(liang)層，裝修簡單。室內設(she)計理念是從少(shao)人值守到無人值守過渡，體(ti)現了“工(gong)業化(hua)”建(jian)筑的(de)特點。據悉(xi)，僅變電(dian)(dian)站(zhan)主控(kong)樓的(de)建(jian)筑面(mian)積就比舊式主控(kong)樓減(jian)(jian)少(shao)50%。該變電(dian)(dian)站(zhan)顯著(zhu)降(jiang)低了工(gong)程成本，方便(bian)了運行維(wei)護(hu)，節約了土地和水(shui)資源。
