9月27日，賽晶(jing)科(ke)技集(ji)團旗下朗德電(dian)氣研(yan)制(zhi)的COM7010柔(rou)直(zhi)(zhi)閥直(zhi)(zhi)流支(zhi)撐電(dian)容器(qi)監測裝置(zhi)，在世界首條柔(rou)性直(zhi)(zhi)流電(dian)網工(gong)程——張(zhang)北柔(rou)性直(zhi)(zhi)流工(gong)程上(shang)掛網試運行(xing)成功，助(zhu)力柔(rou)直(zhi)(zhi)輸電(dian)核心部件(jian)（材料）高(gao)壓大容量(liang)干式直(zhi)(zhi)流電(dian)容器(qi)的國產化應用，為解決制(zhi)約(yue)我國特高(gao)壓重大裝備研(yan)發和制(zhi)造的關鍵“卡脖子(zi)”問題(ti)貢(gong)獻力量(liang)。

隨著“雙碳(tan)”目(mu)標提出，加快建設新型能(neng)(neng)源體系和構(gou)建新型電(dian)(dian)(dian)(dian)(dian)力系統(tong)已經成為廣泛共識。柔性(xing)(xing)直(zhi)流輸(shu)電(dian)(dian)(dian)(dian)(dian)是新一(yi)代(dai)先(xian)進直(zhi)流輸(shu)電(dian)(dian)(dian)(dian)(dian)技術，具(ju)有不存在換相失(shi)敗、能(neng)(neng)夠實現功率(lv)連(lian)續調節(jie)、可向電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)提供電(dian)(dian)(dian)(dian)(dian)壓(ya)和頻率(lv)支持(chi)、輸(shu)出諧(xie)波(bo)少、具(ju)備黑啟動能(neng)(neng)力等突出優(you)點。柔性(xing)(xing)直(zhi)流輸(shu)電(dian)(dian)(dian)(dian)(dian)技術是構(gou)建新型電(dian)(dian)(dian)(dian)(dian)力系統(tong)的(de)關鍵技術，在支撐送(song)端(duan)弱交(jiao)流電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)下(xia)大規模新能(neng)(neng)源送(song)出、提高多直(zhi)流集(ji)中饋(kui)入受端(duan)電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)安(an)全穩定水平、實現大區(qu)電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)異步互聯(lian)等場合具(ju)有迫切(qie)的(de)應(ying)用需(xu)求(qiu)。

直(zhi)(zhi)流(liu)(liu)(liu)支撐電(dian)容(rong)器作為柔(rou)性直(zhi)(zhi)流(liu)(liu)(liu)輸電(dian)系(xi)統中(zhong)電(dian)壓(ya)(ya)源換流(liu)(liu)(liu)器直(zhi)(zhi)流(liu)(liu)(liu)側(ce)(ce)儲(chu)能元件，可(ke)以為換流(liu)(liu)(liu)器提供平滑的直(zhi)(zhi)流(liu)(liu)(liu)電(dian)壓(ya)(ya)，同時能夠緩沖(chong)系(xi)統故障時引起的直(zhi)(zhi)流(liu)(liu)(liu)側(ce)(ce)電(dian)壓(ya)(ya)波動，減少(shao)直(zhi)(zhi)流(liu)(liu)(liu)側(ce)(ce)電(dian)壓(ya)(ya)紋波，并防(fang)止IGBT的直(zhi)(zhi)流(liu)(liu)(liu)過(guo)壓(ya)(ya)過(guo)沖(chong)。長(chang)期(qi)以來我國柔(rou)直(zhi)(zhi)干(gan)式(shi)電(dian)容(rong)器完(wan)全(quan)依賴進口，導(dao)致柔(rou)直(zhi)(zhi)工程(cheng)建設成本提高，關鍵技術和核心(xin)元件受(shou)制(zhi)于人，嚴(yan)重威脅我國電(dian)網發(fa)展和能源安全(quan)。隨著(zhu)我國裝備制(zhi)作工藝水平的提高，已經研制(zhi)出(chu)了(le)國產化(hua)柔(rou)直(zhi)(zhi)用干(gan)式(shi)電(dian)容(rong)器。

張北(bei)柔(rou)性直流電(dian)網(wang)示范(fan)工程(cheng)柔(rou)性直流輸電(dian)裝備(bei)

高(gao)電壓(ya)、大電流沖擊運(yun)行工況會加速電容器(qi)的(de)老化(hua)并最終(zhong)導(dao)致電容器(qi)失效，進而直(zhi)(zhi)接影(ying)響到高(gao)壓(ya)直(zhi)(zhi)流輸電系(xi)統的(de)運(yun)行安(an)全(quan)。朗德研制(zhi)了COM7010柔直(zhi)(zhi)換流閥(fa)直(zhi)(zhi)流支(zhi)撐電容器(qi)在線(xian)監測裝置(zhi)，實(shi)現了電容器(qi)運(yun)行狀(zhuang)態實(shi)時(shi)智能分析，為(wei)柔直(zhi)(zhi)閥(fa)國產直(zhi)(zhi)流支(zhi)撐電容器(qi)安(an)全(quan)可靠(kao)運(yun)行提(ti)供狀(zhuang)態數據支(zhi)撐。

COM7010裝置采(cai)用自(zi)取(qu)能(neng)供電和(he)(he)智能(neng)無線通訊技術，安裝維護方便，安全(quan)可靠；采(cai)用高精度傳感模(mo)塊和(he)(he)抗干擾(rao)技術，保證測量(liang)精度和(he)(he)運(yun)行(xing)穩定性。

“張北的(de)風點(dian)亮北京的(de)燈”，已成一(yi)段佳話。立(li)足(zu)(zu)我國能(neng)源資源與(yu)需求呈現逆向分(fen)布特征(zheng)，考慮新(xin)能(neng)源出力(li)的(de)隨機性(xing)、強時空相關性(xing)，仍(reng)需擴大(da)柔性(xing)直流輸(shu)電(dian)網(wang)規模才能(neng)滿足(zu)(zu)遠距離大(da)容量輸(shu)電(dian)和新(xin)能(neng)源跨(kua)(kua)省跨(kua)(kua)區消(xiao)納需求。朗(lang)德電(dian)氣將秉持采(cai)樣數值化手(shou)段守護電(dian)網(wang)安全(quan)的(de)理念，持續為新(xin)型電(dian)力(li)系統建設貢獻力(li)量。
