2019年(nian)(nian)12月27日，2022年(nian)(nian)北(bei)京冬奧會重點配套工程，也(ye)是世界首個柔(rou)(rou)性直(zhi)流(liu)電網——國家電網張北(bei)柔(rou)(rou)性直(zhi)流(liu)電網試(shi)驗示(shi)范工程（以下(xia)簡(jian)稱(cheng)“張北(bei)柔(rou)(rou)直(zhi)工程”）全(quan)面啟(qi)動調試(shi)，預計(ji)2020年(nian)(nian)上半年(nian)(nian)投產運行。

張(zhang)(zhang)北(bei)柔直工(gong)程(cheng)(cheng)為匯集和輸(shu)送(song)大(da)(da)規模風電(dian)(dian)、光伏、儲能(neng)(neng)、抽蓄等(deng)多種(zhong)形態能(neng)(neng)源(yuan)(yuan)的四端柔性直流電(dian)(dian)網。工(gong)程(cheng)(cheng)正式(shi)投運后(hou)，將依托666千(qian)(qian)米±500千(qian)(qian)伏直流輸(shu)電(dian)(dian)線(xian)路及張(zhang)(zhang)北(bei)、康(kang)保、豐寧(ning)、北(bei)京(jing)(jing)4座換(huan)流站，實現最大(da)(da)輸(shu)送(song)能(neng)(neng)力450萬千(qian)(qian)瓦、總換(huan)流容量(liang)900萬千(qian)(qian)瓦，大(da)(da)幅(fu)提升張(zhang)(zhang)家口(kou)清(qing)(qing)潔(jie)(jie)能(neng)(neng)源(yuan)(yuan)的輸(shu)送(song)能(neng)(neng)力，有效化解張(zhang)(zhang)北(bei)地(di)區(qu)(qu)(qu)千(qian)(qian)萬千(qian)(qian)瓦級清(qing)(qing)潔(jie)(jie)能(neng)(neng)源(yuan)(yuan)消(xiao)納難題(ti)；同(tong)時，每年可向北(bei)京(jing)(jing)地(di)區(qu)(qu)(qu)輸(shu)送(song)清(qing)(qing)潔(jie)(jie)電(dian)(dian)量(liang)約140億千(qian)(qian)瓦時，超(chao)過北(bei)京(jing)(jing)市年用(yong)電(dian)(dian)量(liang)的十分(fen)之(zhi)一，減(jian)少標(biao)煤消(xiao)耗448萬噸、減(jian)排二氧化碳(tan)1165萬噸，大(da)(da)幅(fu)提升北(bei)京(jing)(jing)地(di)區(qu)(qu)(qu)清(qing)(qing)潔(jie)(jie)能(neng)(neng)源(yuan)(yuan)消(xiao)費比重(zhong)。

張(zhang)北柔(rou)直(zhi)工程(cheng)在世(shi)(shi)界(jie)上(shang)首次提(ti)出(chu)了(le)(le)(le)多點匯(hui)集、多點送出(chu)、柔(rou)直(zhi)組(zu)網(wang)、多能(neng)互補的直(zhi)流(liu)(liu)電網(wang)基本概念(nian)與(yu)工程(cheng)方案，示(shi)范了(le)(le)(le)世(shi)(shi)界(jie)上(shang)最(zui)先進的電力(li)生(sheng)產、傳輸、存(cun)儲、利用和運行控制技術，創造(zao)了(le)(le)(le)世(shi)(shi)界(jie)上(shang)最(zui)大功率(lv)全控可關斷(duan)(duan)器件、世(shi)(shi)界(jie)上(shang)最(zui)高電壓等級(ji)最(zui)大換流(liu)(liu)容量柔(rou)性直(zhi)流(liu)(liu)換流(liu)(liu)閥(fa)、世(shi)(shi)界(jie)上(shang)最(zui)高電壓等級(ji)最(zui)大開斷(duan)(duan)能(neng)力(li)直(zhi)流(liu)(liu)斷(duan)(duan)路器等12項世(shi)(shi)界(jie)第一，為(wei)解(jie)決電網(wang)薄弱導致(zhi)的大規模可再生(sheng)能(neng)源匯(hui)集與(yu)送出(chu)困難問題樹立了(le)(le)(le)典范，提(ti)升(sheng)了(le)(le)(le)我國電力(li)科技和電工裝備(bei)制造(zao)的國際(ji)領先地位。
