2019年(nian)(nian)12月27日(ri)，2022年(nian)(nian)北京冬奧(ao)會重點配套工(gong)程，也是世界首個柔性直(zhi)流電網(wang)——國(guo)家電網(wang)張北柔性直(zhi)流電網(wang)試驗示范工(gong)程（以下簡(jian)稱“張北柔直(zhi)工(gong)程”）全面啟動調試，預計2020年(nian)(nian)上(shang)半年(nian)(nian)投(tou)產運行。

張(zhang)(zhang)北柔(rou)(rou)直工程為匯集和(he)輸(shu)(shu)(shu)送大(da)(da)(da)規(gui)模風電(dian)(dian)、光伏、儲(chu)能、抽蓄等多種形態能源(yuan)(yuan)的四端柔(rou)(rou)性直流電(dian)(dian)網。工程正式投運后，將依托666千(qian)(qian)米±500千(qian)(qian)伏直流輸(shu)(shu)(shu)電(dian)(dian)線路及張(zhang)(zhang)北、康保、豐寧(ning)、北京(jing)4座換(huan)流站，實(shi)現最大(da)(da)(da)輸(shu)(shu)(shu)送能力450萬(wan)(wan)千(qian)(qian)瓦(wa)、總換(huan)流容量900萬(wan)(wan)千(qian)(qian)瓦(wa)，大(da)(da)(da)幅提升張(zhang)(zhang)家(jia)口清(qing)潔能源(yuan)(yuan)的輸(shu)(shu)(shu)送能力，有效(xiao)化解(jie)張(zhang)(zhang)北地(di)區千(qian)(qian)萬(wan)(wan)千(qian)(qian)瓦(wa)級清(qing)潔能源(yuan)(yuan)消(xiao)納難題；同時(shi)，每(mei)年可向北京(jing)地(di)區輸(shu)(shu)(shu)送清(qing)潔電(dian)(dian)量約140億千(qian)(qian)瓦(wa)時(shi)，超過北京(jing)市年用電(dian)(dian)量的十分(fen)之一(yi)，減少標煤消(xiao)耗448萬(wan)(wan)噸、減排二氧化碳1165萬(wan)(wan)噸，大(da)(da)(da)幅提升北京(jing)地(di)區清(qing)潔能源(yuan)(yuan)消(xiao)費比重。

張北柔直(zhi)工(gong)程在世(shi)(shi)界(jie)(jie)上首次提出(chu)了(le)(le)多點匯集、多點送(song)出(chu)、柔直(zhi)組網(wang)、多能(neng)互(hu)補的(de)直(zhi)流(liu)電網(wang)基本概念(nian)與(yu)(yu)工(gong)程方案，示(shi)范(fan)了(le)(le)世(shi)(shi)界(jie)(jie)上最(zui)先(xian)進的(de)電力(li)生(sheng)產、傳輸、存儲、利(li)用和運行(xing)控(kong)制技術(shu)，創(chuang)造(zao)了(le)(le)世(shi)(shi)界(jie)(jie)上最(zui)大(da)(da)功率全控(kong)可關斷器(qi)件、世(shi)(shi)界(jie)(jie)上最(zui)高電壓等(deng)(deng)級最(zui)大(da)(da)換流(liu)容量柔性(xing)直(zhi)流(liu)換流(liu)閥、世(shi)(shi)界(jie)(jie)上最(zui)高電壓等(deng)(deng)級最(zui)大(da)(da)開斷能(neng)力(li)直(zhi)流(liu)斷路器(qi)等(deng)(deng)12項世(shi)(shi)界(jie)(jie)第一，為解決電網(wang)薄弱導致的(de)大(da)(da)規模可再生(sheng)能(neng)源匯集與(yu)(yu)送(song)出(chu)困難問題樹立了(le)(le)典(dian)范(fan)，提升了(le)(le)我國電力(li)科技和電工(gong)裝備制造(zao)的(de)國際領先(xian)地位。
