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(sha)永興島原(yuan)來(lai)由2臺(tai)(tai)500千(qian)瓦柴油發電(dian)(dian)(dian)機(ji)組供(gong)電(dian)(dian)(dian)，可靠性差。該工程是南(nan)方電(dian)(dian)(dian)網(wang)(wang)三沙(sha)供(gong)電(dian)(dian)(dian)局成立以(yi)來(lai)第一個(ge)電(dian)(dian)(dian)網(wang)(wang)改造項目。此次改造將原(yuan)機(ji)房已損壞(huai)的200千(qian)瓦發電(dian)(dian)(dian)機(ji)拆除，新增1臺(tai)(tai)500千(qian)瓦柴油發電(dian)(dian)(dian)機(ji)，總裝(zhuang)機(ji)容(rong)量(liang)達到1500千(qian)瓦。同時，新建1座預裝(zhuang)箱(xiang)式(shi)10千(qian)伏(fu)升壓站；新增4臺(tai)(tai)環(huan)(huan)網(wang)(wang)柜和4臺(tai)(tai)箱(xiang)變(bian)及相關配套(tao)設備；從升壓站新建兩回10千(qian)伏(fu)電(dian)(dian)(dian)纜(lan)線路，形成“2-1”單環(huan)(huan)網(wang)(wang)接線；新建10千(qian)伏(fu)電(dian)(dian)(dian)纜(lan)線路3公里(li)，新建400伏(fu)電(dian)(dian)(dian)纜(lan)線路2.8公里(li)。
