近日，廣東電網汕頭供電局和南澳縣政府舉行國家“863”計劃“柔性多端直流輸電工程”項目啟動暨簽字儀式，標志著南方電網公司首個柔性多端直流輸電工程落戶廣東汕頭南澳縣。
汕(shan)頭(tou)南澳島(dao)域風能(neng)資(zi)源(yuan)豐富，且風能(neng)發電(dian)(dian)(dian)(dian)(dian)項(xiang)目開(kai)發較早，現已(yi)初具(ju)規(gui)模，但因風電(dian)(dian)(dian)(dian)(dian)波動(dong)性、間隙性較強(qiang)的特點，采用傳統交(jiao)流并網(wang)存在一(yi)定技(ji)(ji)術瓶頸(jing)。該項(xiang)目計劃建成(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)壓等(deng)級為±160千伏，輸(shu)送(song)容(rong)量為20萬千瓦的多端柔(rou)性直流輸(shu)電(dian)(dian)(dian)(dian)(dian)系統，可有效解(jie)決上述問(wen)題，實現大型(xing)風電(dian)(dian)(dian)(dian)(dian)場柔(rou)性直流接(jie)入，保障大規(gui)模風電(dian)(dian)(dian)(dian)(dian)的穩定、可靠送(song)出。目前，工程項(xiang)目投(tou)資(zi)規(gui)模初步估算已(yi)超過7.4億元，由南方電(dian)(dian)(dian)(dian)(dian)網(wang)科學研究院牽(qian)頭(tou)實施，廣東電(dian)(dian)(dian)(dian)(dian)網(wang)公司及汕(shan)頭(tou)供(gong)電(dian)(dian)(dian)(dian)(dian)局負(fu)責(ze)工程建設，計劃于2013年12月底前建成(cheng)(cheng)投(tou)產。投(tou)產后將在分布式(shi)可再生能(neng)源(yuan)、孤島(dao)供(gong)電(dian)(dian)(dian)(dian)(dian)、城市電(dian)(dian)(dian)(dian)(dian)網(wang)供(gong)電(dian)(dian)(dian)(dian)(dian)等(deng)領域實現突破，提升電(dian)(dian)(dian)(dian)(dian)網(wang)整體科技(ji)(ji)及裝備水平(ping)。
