2月21日(ri)，我國首條公(gong)里級高溫超導電(dian)(dian)纜示范工(gong)程在上海啟動建(jian)設，標志著我國超導電(dian)(dian)纜工(gong)程化應用正式起步。當天，國網上海市電(dian)(dian)力公(gong)司與承擔超導電(dian)(dian)纜研制的上海電(dian)(dian)纜研究所(suo)簽訂了戰略合作協議(yi)。
示范工程綜合(he)考(kao)慮了我國當前高溫(wen)超導(dao)電(dian)(dian)纜(lan)技(ji)術能力，充分發揮超導(dao)電(dian)(dian)纜(lan)的大容(rong)量輸送能力及(ji)可靠性(xing)，將在220千(qian)(qian)伏(fu)長春變電(dian)(dian)站至35千(qian)(qian)伏(fu)漕溪變電(dian)(dian)站間建(jian)設一條35千(qian)(qian)伏(fu)高溫(wen)超導(dao)電(dian)(dian)纜(lan)互饋線(xian)，最(zui)大設計電(dian)(dian)流(liu)2200安，代替現有4回(hui)35千(qian)(qian)伏(fu)常規電(dian)(dian)纜(lan)互饋線(xian)。正常運行方(fang)式下，超導(dao)電(dian)(dian)纜(lan)供電(dian)(dian)負(fu)荷約6萬千(qian)(qian)瓦(wa)、負(fu)載(zai)率50%；特(te)殊運行方(fang)式下，供電(dian)(dian)負(fu)荷約12萬千(qian)(qian)瓦(wa)、負(fu)載(zai)率100%。
高溫(wen)超(chao)導電(dian)纜在(zai)城市電(dian)網(wang)(wang)中的實際應用將成為(wei)(wei)我國電(dian)網(wang)(wang)發展建設的重(zhong)要里程碑。示范(fan)工程將為(wei)(wei)城市電(dian)網(wang)(wang)建設提(ti)供(gong)強大(da)的技(ji)術支撐，可有效解(jie)決負荷密集城市電(dian)纜通道資(zi)源緊(jin)張難題。
自2016年(nian)起(qi)，國網(wang)上海電(dian)力(li)在(zai)上海市(shi)經(jing)信(xin)委指(zhi)導(dao)(dao)下，與上海電(dian)纜研(yan)(yan)(yan)究(jiu)所及(ji)帶(dai)材(cai)企(qi)業(ye)開展合(he)作，研(yan)(yan)(yan)究(jiu)高溫超(chao)導(dao)(dao)電(dian)纜工程化應用(yong)技(ji)(ji)術(shu)。去年(nian)，國網(wang)上海電(dian)力(li)正(zheng)式啟動高溫超(chao)導(dao)(dao)電(dian)纜示(shi)范建(jian)設研(yan)(yan)(yan)究(jiu)，為(wei)示(shi)范工程建(jian)設奠定重要基礎。項目前期(qi)，國網(wang)上海電(dian)力(li)攜(xie)手中(zhong)國電(dian)科院、國網(wang)經(jing)研(yan)(yan)(yan)院、上海電(dian)纜研(yan)(yan)(yan)究(jiu)所等(deng)單位開展技(ji)(ji)術(shu)攻關，在(zai)超(chao)導(dao)(dao)電(dian)纜在(zai)城市(shi)電(dian)網(wang)中(zhong)的規劃(hua)技(ji)(ji)術(shu)及(ji)運行方式研(yan)(yan)(yan)究(jiu)、公里級(ji)超(chao)導(dao)(dao)電(dian)纜關鍵技(ji)(ji)術(shu)研(yan)(yan)(yan)究(jiu)等(deng)方面(mian)取得創新成果。
