近日，我國首(shou)個(ge)同(tong)時也是亞洲首(shou)個(ge)采(cai)用柔性直流輸(shu)電技術(shu)送(song)出的海上風電項(xiang)目(mu)——三峽(xia)集團(tuan)江蘇如(ru)東(dong)800兆(zhao)瓦（H6、H10）海上風電項(xiang)目(mu)（以下簡稱(cheng)“三峽(xia)如(ru)東(dong)項(xiang)目(mu)”），累計生產清潔電能突(tu)破(po)50億千瓦時，相當于減少標準煤消耗約(yue)150萬(wan)噸，二(er)氧化碳(tan)排(pai)放約(yue)375萬(wan)噸。

柔性直流(liu)(liu)輸(shu)電(dian)(dian)(dian)(dian)技(ji)術是目前世界上最前沿(yan)的輸(shu)電(dian)(dian)(dian)(dian)技(ji)術，特別適用于長距離的跨(kua)海(hai)電(dian)(dian)(dian)(dian)纜送電(dian)(dian)(dian)(dian)、可(ke)再(zai)生(sheng)能(neng)源并(bing)網(wang)(wang)(wang)、分布式發電(dian)(dian)(dian)(dian)并(bing)網(wang)(wang)(wang)、孤島供電(dian)(dian)(dian)(dian)（黑啟動）、異(yi)步交流(liu)(liu)電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)互聯等領域。如果(guo)把電(dian)(dian)(dian)(dian)流(liu)(liu)比(bi)喻成水(shui)(shui)流(liu)(liu)，那么柔性直流(liu)(liu)技(ji)術就相當(dang)于一個精(jing)(jing)準(zhun)的“攔(lan)水(shui)(shui)壩”，能(neng)夠精(jing)(jing)準(zhun)控制水(shui)(shui)流(liu)(liu)的方向、速度(du)和流(liu)(liu)量，使(shi)水(shui)(shui)庫水(shui)(shui)位更(geng)(geng)加平穩。除此(ci)之(zhi)外(wai)，柔性直流(liu)(liu)輸(shu)電(dian)(dian)(dian)(dian)技(ji)術還可(ke)以將遠海(hai)的電(dian)(dian)(dian)(dian)能(neng)轉換為損耗更(geng)(geng)低(di)的直流(liu)(liu)電(dian)(dian)(dian)(dian)，相比(bi)傳統輸(shu)電(dian)(dian)(dian)(dian)方式具有更(geng)(geng)好(hao)的經濟性優勢。

三(san)峽如東項目(mu)(mu)(mu)建成亞洲首座海(hai)(hai)上(shang)換流站，總重(zhong)量(liang)達到(dao)22000噸，采(cai)用(yong)(yong)浮(fu)托(tuo)法安裝(zhuang)，這也是國內(nei)首次采(cai)用(yong)(yong)浮(fu)托(tuo)法安裝(zhuang)的(de)海(hai)(hai)上(shang)換流站。項目(mu)(mu)(mu)直流海(hai)(hai)纜使用(yong)(yong)±400千伏(fu)電(dian)壓等(deng)級(ji)，海(hai)(hai)纜長度達到(dao)99公里，為(wei)目(mu)(mu)(mu)前國內(nei)最長的(de)柔(rou)性(xing)直流輸(shu)電(dian)電(dian)纜。項目(mu)(mu)(mu)多個首次的(de)集(ji)合運用(yong)(yong)，為(wei)海(hai)(hai)上(shang)風電(dian)深遠海(hai)(hai)大規模(mo)開發(fa)提(ti)供了關鍵解決方(fang)案。
