近日，我(wo)國首個同時也是亞洲首個采用柔性直(zhi)流輸電(dian)技(ji)術(shu)送出的海上(shang)風(feng)電(dian)項(xiang)目(mu)——三(san)峽集團江蘇如(ru)東800兆(zhao)瓦（H6、H10）海上(shang)風(feng)電(dian)項(xiang)目(mu)（以下簡稱“三(san)峽如(ru)東項(xiang)目(mu)”），累計生(sheng)產清(qing)潔電(dian)能突破50億千瓦時，相當于減(jian)少標準煤消耗約150萬噸，二氧化碳排放約375萬噸。

柔(rou)性(xing)直(zhi)流(liu)輸(shu)電(dian)(dian)(dian)(dian)技(ji)術(shu)是目前(qian)世界上最前(qian)沿的(de)(de)輸(shu)電(dian)(dian)(dian)(dian)技(ji)術(shu)，特別適用于長距離的(de)(de)跨海電(dian)(dian)(dian)(dian)纜送(song)電(dian)(dian)(dian)(dian)、可(ke)再生能源并(bing)網、分布式(shi)發(fa)電(dian)(dian)(dian)(dian)并(bing)網、孤島供電(dian)(dian)(dian)(dian)（黑啟動）、異步交流(liu)電(dian)(dian)(dian)(dian)網互聯等領域。如果把電(dian)(dian)(dian)(dian)流(liu)比(bi)喻(yu)成水(shui)(shui)流(liu)，那(nei)么柔(rou)性(xing)直(zhi)流(liu)技(ji)術(shu)就相當于一個(ge)精準(zhun)的(de)(de)“攔(lan)水(shui)(shui)壩”，能夠精準(zhun)控制水(shui)(shui)流(liu)的(de)(de)方(fang)向、速(su)度和流(liu)量(liang)，使(shi)水(shui)(shui)庫水(shui)(shui)位(wei)更(geng)加(jia)平穩。除(chu)此之外，柔(rou)性(xing)直(zhi)流(liu)輸(shu)電(dian)(dian)(dian)(dian)技(ji)術(shu)還(huan)可(ke)以將遠海的(de)(de)電(dian)(dian)(dian)(dian)能轉換(huan)為損耗(hao)更(geng)低的(de)(de)直(zhi)流(liu)電(dian)(dian)(dian)(dian)，相比(bi)傳統(tong)輸(shu)電(dian)(dian)(dian)(dian)方(fang)式(shi)具有更(geng)好的(de)(de)經濟(ji)性(xing)優勢。

三峽如東項目(mu)建成(cheng)亞洲(zhou)首(shou)座(zuo)海(hai)上(shang)換(huan)流站(zhan)，總重量達到(dao)22000噸，采(cai)用(yong)(yong)浮托法(fa)安(an)裝(zhuang)(zhuang)，這(zhe)也是(shi)國(guo)內首(shou)次采(cai)用(yong)(yong)浮托法(fa)安(an)裝(zhuang)(zhuang)的海(hai)上(shang)換(huan)流站(zhan)。項目(mu)直流海(hai)纜(lan)使用(yong)(yong)±400千伏電(dian)壓等(deng)級，海(hai)纜(lan)長(chang)度達到(dao)99公里，為(wei)目(mu)前國(guo)內最(zui)長(chang)的柔性直流輸(shu)電(dian)電(dian)纜(lan)。項目(mu)多個首(shou)次的集(ji)合運用(yong)(yong)，為(wei)海(hai)上(shang)風電(dian)深遠海(hai)大規模開(kai)發提供了關鍵解決方案。
