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。
三沙永興(xing)島原來(lai)由(you)2臺500千(qian)瓦柴油(you)發電(dian)(dian)(dian)機(ji)(ji)組供電(dian)(dian)(dian)，可靠性差。該工(gong)程是南(nan)方電(dian)(dian)(dian)網(wang)三沙供電(dian)(dian)(dian)局成立以來(lai)第一(yi)個(ge)電(dian)(dian)(dian)網(wang)改造(zao)項(xiang)目。此次(ci)改造(zao)將原機(ji)(ji)房已損壞的200千(qian)瓦發電(dian)(dian)(dian)機(ji)(ji)拆除，新增(zeng)(zeng)1臺500千(qian)瓦柴油(you)發電(dian)(dian)(dian)機(ji)(ji)，總裝機(ji)(ji)容量(liang)達到1500千(qian)瓦。同(tong)時(shi)，新建1座預裝箱式10千(qian)伏升壓站；新增(zeng)(zeng)4臺環網(wang)柜和4臺箱變及相關配(pei)套設備(bei)；從升壓站新建兩回10千(qian)伏電(dian)(dian)(dian)纜(lan)(lan)線(xian)路(lu)，形成“2-1”單環網(wang)接線(xian)；新建10千(qian)伏電(dian)(dian)(dian)纜(lan)(lan)線(xian)路(lu)3公里，新建400伏電(dian)(dian)(dian)纜(lan)(lan)線(xian)路(lu)2.8公里。
