經過湖(hu)南省(sheng)電(dian)力(li)公(gong)(gong)司(si)電(dian)網(wang)建設(she)(she)運行分公(gong)(gong)司(si)、湖(hu)南省(sheng)電(dian)網(wang)建設(she)(she)公(gong)(gong)司(si)、湖(hu)南省(sheng)電(dian)力(li)設(she)(she)計院(yuan)等(deng)參建單位(wei)一年(nian)多的共同努力(li)，2009年(nian)12月28日，湖(hu)南省(sheng)首座“兩型(xing)一化”500千(qian)伏永州南（紫霞）變電(dian)站建成(cheng)投運，標志著(zhu)湖(hu)南500千(qian)伏“三橫”“兩縱”“兩環網(wang)”主(zhu)網(wang)架基本形成(cheng)。
500千(qian)伏(fu)永州南變電站(zhan)位于(yu)永州市寧遠縣舜陵(ling)鎮紫霞街(jie)，本期建(jian)設規模為一臺75萬千(qian)伏(fu)安主變壓器，配套建(jian)設500千(qian)伏(fu)線(xian)路(lu)2回、221千(qian)米，220千(qian)伏(fu)線(xian)路(lu)5回、80千(qian)米，輸變電工(gong)(gong)程(cheng)共計(ji)投(tou)(tou)資近10億元。工(gong)(gong)程(cheng)于(yu)2008年10月底(di)開工(gong)(gong)，2009年4月開始基礎施工(gong)(gong)，12月28日正(zheng)式投(tou)(tou)運。
該(gai)變(bian)電(dian)(dian)(dian)站(zhan)(zhan)的(de)投(tou)(tou)運，大(da)大(da)加強了湘(xiang)南(nan)(nan)(nan)電(dian)(dian)(dian)網(wang)結構和(he)永州南(nan)(nan)(nan)部電(dian)(dian)(dian)網(wang)供(gong)電(dian)(dian)(dian)能力(li)，解(jie)決了永州電(dian)(dian)(dian)力(li)供(gong)應瓶頸問題；改(gai)寫了永州電(dian)(dian)(dian)網(wang)通(tong)過(guo)2條(tiao)220千(qian)伏線(xian)路(lu)供(gong)帶4座220千(qian)伏變(bian)電(dian)(dian)(dian)站(zhan)(zhan)的(de)歷史(shi)，對永州電(dian)(dian)(dian)網(wang)的(de)穩定起(qi)著重要(yao)作用；有利于西(xi)部電(dian)(dian)(dian)力(li)在永州電(dian)(dian)(dian)網(wang)的(de)消納并轉(zhuan)送至(zhi)郴州電(dian)(dian)(dian)網(wang)。該(gai)工程是湖(hu)南(nan)(nan)(nan)公司(si)標準化建設示范項目，也是湖(hu)南(nan)(nan)(nan)公司(si)2009年(nian)電(dian)(dian)(dian)網(wang)建設的(de)收官之(zhi)作。據悉，截至(zhi)2009年(nian)12月底，湖(hu)南(nan)(nan)(nan)超高(gao)壓電(dian)(dian)(dian)網(wang)投(tou)(tou)運500千(qian)伏變(bian)電(dian)(dian)(dian)站(zhan)(zhan)15座、開關站(zhan)(zhan)1座，投(tou)(tou)運輸電(dian)(dian)(dian)線(xian)路(lu)40條(tiao)4326千(qian)米。
該(gai)變電(dian)站(zhan)作(zuo)為湖南省首座資(zi)源節約(yue)型(xing)、環境友好型(xing)、工(gong)業化的(de)500千伏變電(dian)站(zhan)，按照“三通一標”原則建設。變電(dian)站(zhan)內各設備區除了(le)由混凝土(tu)路面相連(lian)，其余所有空(kong)地覆蓋(gai)著拇(mu)指大小(xiao)的(de)白色碎石(shi)，不再種植花(hua)草，這樣可減少(shao)(shao)(shao)后期維(wei)護(hu)、節約(yue)水資(zi)源。此外，變電(dian)站(zhan)內的(de)建筑數量顯(xian)著減少(shao)(shao)(shao)，主(zhu)控(kong)樓(lou)只有兩(liang)層(ceng)，裝修簡(jian)單。室內設計理念(nian)是從少(shao)(shao)(shao)人值守(shou)到無人值守(shou)過(guo)渡(du)，體現(xian)了(le)“工(gong)業化”建筑的(de)特點。據悉，僅變電(dian)站(zhan)主(zhu)控(kong)樓(lou)的(de)建筑面積就比(bi)舊式主(zhu)控(kong)樓(lou)減少(shao)(shao)(shao)50%。該(gai)變電(dian)站(zhan)顯(xian)著降低了(le)工(gong)程成本，方便了(le)運行維(wei)護(hu)，節約(yue)了(le)土(tu)地和水資(zi)源。
