近日，國家“十一(yi)五(wu)”重點建設項(xiang)目、南方(fang)電網重點工(gong)程——500千伏(fu)(fu)賢令山變(bian)電站和500千伏(fu)(fu)山花甲乙線(xian)一(yi)次投運(yun)成功，標志著清遠市首座500千伏(fu)(fu)變(bian)電站竣工(gong)，這是南方(fang)電網西(xi)電東送通(tong)道的一(yi)個支撐點。
賢令山輸(shu)變(bian)電(dian)工程(cheng)是(shi)清(qing)遠第一(yi)個500千(qian)伏(fu)(fu)(fu)輸(shu)變(bian)電(dian)工程(cheng)，也是(shi)清(qing)遠建(jian)市以來(lai)投(tou)資(zi)最大(da)、電(dian)壓(ya)等級最高的一(yi)項輸(shu)變(bian)電(dian)工程(cheng)。該(gai)工程(cheng)最終建(jian)設(she)規模為：建(jian)設(she)3組75萬(wan)千(qian)伏(fu)(fu)(fu)安主變(bian)壓(ya)器，500千(qian)伏(fu)(fu)(fu)出線9回，220千(qian)伏(fu)(fu)(fu)出線14回。
該(gai)工程投運后，形(xing)成500千伏(fu)貴州(zhou)施秉—廣西桂林—清(qing)(qing)遠(yuan)賢令山—廣州(zhou)花都(dou)交流通道(dao)，進(jin)一步增(zeng)強廣東500千伏(fu)骨干電(dian)(dian)(dian)(dian)網覆蓋(gai)面，滿足“十一五(wu)”西電(dian)(dian)(dian)(dian)東送需要，提高南方電(dian)(dian)(dian)(dian)網的(de)輸電(dian)(dian)(dian)(dian)能(neng)力及安(an)全穩定(ding)運行。同時能(neng)滿足近期及遠(yuan)期清(qing)(qing)遠(yuan)電(dian)(dian)(dian)(dian)力送出(chu)，有效解(jie)決(jue)“三連一陽(yang)”小(xiao)水電(dian)(dian)(dian)(dian)送網“卡(ka)脖(bo)子”的(de)問(wen)題，提高了清(qing)(qing)遠(yuan)電(dian)(dian)(dian)(dian)網供電(dian)(dian)(dian)(dian)能(neng)力和安(an)全可靠性。
