9月13日，南方電網公司負責建設的國內首條±160千伏海底直流電纜在廣東汕頭南澳海域開始敷設。該海底電纜起點位于汕頭市澄海區萊蕪終端場，終點位于汕頭南澳島長山尾終端場，線路全長約9.3公里，整個海纜敷設工程預計9月21日完成。
該海底電(dian)(dian)(dian)(dian)纜(lan)是世界首個多(duo)端(duan)柔性(xing)直(zhi)流(liu)輸(shu)(shu)電(dian)(dian)(dian)(dian)系統項目——廣東(dong)南(nan)澳島柔性(xing)多(duo)端(duan)直(zhi)流(liu)輸(shu)(shu)電(dian)(dian)(dian)(dian)示范(fan)工(gong)程(cheng)（電(dian)(dian)(dian)(dian)壓等(deng)級(ji)±160千(qian)伏，輸(shu)(shu)送容(rong)量(liang)20萬千(qian)瓦(wa)）的(de)重(zhong)要組成部(bu)分。該項目是國家“863計劃”先進能(neng)源技術領域智能(neng)電(dian)(dian)(dian)(dian)網(wang)關(guan)鍵(jian)技術研發(一期)重(zhong)大(da)項目“大(da)型風電(dian)(dian)(dian)(dian)場柔性(xing)直(zhi)流(liu)輸(shu)(shu)電(dian)(dian)(dian)(dian)接入技術研究(jiu)與開發”課題的(de)示范(fan)工(gong)程(cheng)。采用柔性(xing)直(zhi)流(liu)輸(shu)(shu)電(dian)(dian)(dian)(dian)技術，可(ke)攜帶(dai)來自多(duo)個站點的(de)風能(neng)、太陽(yang)能(neng)、地熱(re)能(neng)等(deng)清潔能(neng)源，通過一個大(da)容(rong)量(liang)、長距離的(de)電(dian)(dian)(dian)(dian)力(li)傳輸(shu)(shu)通道，到達多(duo)個城(cheng)(cheng)市的(de)負荷中心。這為新(xin)能(neng)源并網(wang)、大(da)型城(cheng)(cheng)市供(gong)電(dian)(dian)(dian)(dian)以(yi)及(ji)孤島供(gong)電(dian)(dian)(dian)(dian)等(deng)場合(he)提供(gong)了一種(zhong)有效的(de)解決方案。
