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。
汕頭南(nan)(nan)澳島域(yu)風(feng)能(neng)資源(yuan)豐富，且風(feng)能(neng)發電(dian)(dian)(dian)(dian)項目開(kai)發較(jiao)早，現已初具規模(mo)(mo)，但因風(feng)電(dian)(dian)(dian)(dian)波(bo)動性(xing)、間(jian)隙性(xing)較(jiao)強的(de)(de)特點，采用(yong)傳統交流(liu)(liu)并(bing)網(wang)存在一(yi)定技術瓶頸。該項目計劃建(jian)成(cheng)電(dian)(dian)(dian)(dian)壓等級為±160千伏，輸(shu)送(song)容(rong)量為20萬千瓦的(de)(de)多端柔(rou)性(xing)直流(liu)(liu)輸(shu)電(dian)(dian)(dian)(dian)系統，可(ke)有效(xiao)解決上(shang)述問(wen)題，實(shi)(shi)現大型風(feng)電(dian)(dian)(dian)(dian)場柔(rou)性(xing)直流(liu)(liu)接入，保(bao)障大規模(mo)(mo)風(feng)電(dian)(dian)(dian)(dian)的(de)(de)穩定、可(ke)靠送(song)出。目前，工程(cheng)項目投(tou)資規模(mo)(mo)初步估算已超過7.4億元，由南(nan)(nan)方電(dian)(dian)(dian)(dian)網(wang)科(ke)學研究院牽頭實(shi)(shi)施，廣東(dong)電(dian)(dian)(dian)(dian)網(wang)公司及汕頭供(gong)電(dian)(dian)(dian)(dian)局負(fu)責工程(cheng)建(jian)設，計劃于2013年12月底前建(jian)成(cheng)投(tou)產(chan)。投(tou)產(chan)后將(jiang)在分(fen)布式可(ke)再生能(neng)源(yuan)、孤島供(gong)電(dian)(dian)(dian)(dian)、城市電(dian)(dian)(dian)(dian)網(wang)供(gong)電(dian)(dian)(dian)(dian)等領域(yu)實(shi)(shi)現突(tu)破，提升電(dian)(dian)(dian)(dian)網(wang)整體科(ke)技及裝備水平(ping)。
