日前，南方電網建成投運海南三沙永興島電網升壓改造工程，實現電力專業化運營管理，進一步提升了三沙永興島供電可靠性和供電服務水平。
三(san)沙永興島原(yuan)來由2臺500千(qian)瓦柴油發電(dian)(dian)機(ji)組(zu)供(gong)(gong)電(dian)(dian)，可靠性差。該工程是南方電(dian)(dian)網(wang)(wang)(wang)三(san)沙供(gong)(gong)電(dian)(dian)局(ju)成立以來第一個電(dian)(dian)網(wang)(wang)(wang)改造項目。此次改造將原(yuan)機(ji)房(fang)已(yi)損壞的200千(qian)瓦發電(dian)(dian)機(ji)拆除，新(xin)(xin)增1臺500千(qian)瓦柴油發電(dian)(dian)機(ji)，總裝機(ji)容量達到1500千(qian)瓦。同時，新(xin)(xin)建(jian)(jian)1座預裝箱式10千(qian)伏(fu)升壓(ya)站(zhan)；新(xin)(xin)增4臺環網(wang)(wang)(wang)柜和4臺箱變及相(xiang)關配套設備；從升壓(ya)站(zhan)新(xin)(xin)建(jian)(jian)兩回10千(qian)伏(fu)電(dian)(dian)纜線(xian)路，形(xing)成“2-1”單環網(wang)(wang)(wang)接線(xian)；新(xin)(xin)建(jian)(jian)10千(qian)伏(fu)電(dian)(dian)纜線(xian)路3公里，新(xin)(xin)建(jian)(jian)400伏(fu)電(dian)(dian)纜線(xian)路2.8公里。
