2月21日，我國首條公(gong)里級高溫超(chao)導電纜示范工程(cheng)在上海啟(qi)動建設，標志著我國超(chao)導電纜工程(cheng)化(hua)應用正式(shi)起步(bu)。當天(tian)，國網上海市(shi)電力公(gong)司(si)與承擔超(chao)導電纜研制的上海電纜研究所簽訂了戰略合(he)作協議。
示范工程綜合考慮了我(wo)國當前高溫(wen)超(chao)導(dao)(dao)電(dian)(dian)(dian)(dian)(dian)纜技術能力，充分發揮超(chao)導(dao)(dao)電(dian)(dian)(dian)(dian)(dian)纜的大容量(liang)輸送能力及可靠性，將在(zai)220千(qian)(qian)伏長春變電(dian)(dian)(dian)(dian)(dian)站至35千(qian)(qian)伏漕溪變電(dian)(dian)(dian)(dian)(dian)站間建設一條35千(qian)(qian)伏高溫(wen)超(chao)導(dao)(dao)電(dian)(dian)(dian)(dian)(dian)纜互饋(kui)線(xian)，最(zui)大設計電(dian)(dian)(dian)(dian)(dian)流2200安(an)，代(dai)替(ti)現有4回35千(qian)(qian)伏常規電(dian)(dian)(dian)(dian)(dian)纜互饋(kui)線(xian)。正(zheng)常運行方式(shi)下，超(chao)導(dao)(dao)電(dian)(dian)(dian)(dian)(dian)纜供電(dian)(dian)(dian)(dian)(dian)負荷約(yue)6萬(wan)千(qian)(qian)瓦、負載率50%；特殊運行方式(shi)下，供電(dian)(dian)(dian)(dian)(dian)負荷約(yue)12萬(wan)千(qian)(qian)瓦、負載率100%。
高溫超導電(dian)(dian)纜(lan)在城(cheng)市(shi)電(dian)(dian)網中的(de)實際應用(yong)將成(cheng)為(wei)我(wo)國電(dian)(dian)網發(fa)展(zhan)建(jian)設的(de)重要里(li)程碑(bei)。示范工(gong)程將為(wei)城(cheng)市(shi)電(dian)(dian)網建(jian)設提供(gong)強大的(de)技術支撐(cheng)，可(ke)有效(xiao)解決負(fu)荷(he)密(mi)集城(cheng)市(shi)電(dian)(dian)纜(lan)通道資源緊張難題。
自2016年(nian)起，國(guo)網上(shang)(shang)(shang)海(hai)電(dian)力在上(shang)(shang)(shang)海(hai)市經(jing)信委(wei)指(zhi)導(dao)(dao)下，與上(shang)(shang)(shang)海(hai)電(dian)纜(lan)(lan)研(yan)究所(suo)及帶材企業開展合作，研(yan)究高溫(wen)超導(dao)(dao)電(dian)纜(lan)(lan)工程(cheng)(cheng)化(hua)應用技(ji)術。去年(nian)，國(guo)網上(shang)(shang)(shang)海(hai)電(dian)力正式啟動高溫(wen)超導(dao)(dao)電(dian)纜(lan)(lan)示范建設研(yan)究，為(wei)示范工程(cheng)(cheng)建設奠定重要(yao)基礎。項目前期(qi)，國(guo)網上(shang)(shang)(shang)海(hai)電(dian)力攜手中國(guo)電(dian)科院、國(guo)網經(jing)研(yan)院、上(shang)(shang)(shang)海(hai)電(dian)纜(lan)(lan)研(yan)究所(suo)等單位開展技(ji)術攻關，在超導(dao)(dao)電(dian)纜(lan)(lan)在城(cheng)市電(dian)網中的規劃技(ji)術及運行方(fang)(fang)式研(yan)究、公里級超導(dao)(dao)電(dian)纜(lan)(lan)關鍵技(ji)術研(yan)究等方(fang)(fang)面取得創新成果。
