2月21日，我國首(shou)條公里級(ji)高溫(wen)超(chao)導電(dian)(dian)(dian)纜示(shi)范(fan)工程在上海(hai)(hai)啟(qi)動建設，標志(zhi)著(zhu)我國超(chao)導電(dian)(dian)(dian)纜工程化應用正式起步。當天，國網上海(hai)(hai)市電(dian)(dian)(dian)力公司與承擔超(chao)導電(dian)(dian)(dian)纜研制的上海(hai)(hai)電(dian)(dian)(dian)纜研究所(suo)簽訂(ding)了戰略合作(zuo)協議。
示(shi)范工(gong)程(cheng)綜合考(kao)慮了我國當前高(gao)溫超導電(dian)(dian)纜(lan)技術能力，充分發揮超導電(dian)(dian)纜(lan)的大(da)容量輸送能力及可靠性，將在220千(qian)(qian)(qian)伏長春變(bian)電(dian)(dian)站至(zhi)35千(qian)(qian)(qian)伏漕(cao)溪變(bian)電(dian)(dian)站間建設(she)一(yi)條35千(qian)(qian)(qian)伏高(gao)溫超導電(dian)(dian)纜(lan)互饋(kui)線，最大(da)設(she)計電(dian)(dian)流2200安，代替(ti)現(xian)有4回35千(qian)(qian)(qian)伏常(chang)規(gui)電(dian)(dian)纜(lan)互饋(kui)線。正常(chang)運行方(fang)式下(xia)，超導電(dian)(dian)纜(lan)供電(dian)(dian)負(fu)(fu)荷約6萬(wan)(wan)千(qian)(qian)(qian)瓦、負(fu)(fu)載(zai)率50%；特殊運行方(fang)式下(xia)，供電(dian)(dian)負(fu)(fu)荷約12萬(wan)(wan)千(qian)(qian)(qian)瓦、負(fu)(fu)載(zai)率100%。
高(gao)溫(wen)超導電纜在城(cheng)(cheng)市(shi)(shi)電網中的(de)實(shi)際應用將(jiang)成為我國電網發展建設(she)的(de)重要里程碑。示范(fan)工程將(jiang)為城(cheng)(cheng)市(shi)(shi)電網建設(she)提供強大的(de)技術支撐，可有效解決(jue)負荷密集城(cheng)(cheng)市(shi)(shi)電纜通道資源緊張(zhang)難題。
自2016年(nian)起，國(guo)網上(shang)(shang)海電(dian)(dian)力(li)在上(shang)(shang)海市經信委(wei)指導(dao)(dao)下(xia)，與上(shang)(shang)海電(dian)(dian)纜(lan)(lan)研(yan)(yan)(yan)究(jiu)所及(ji)帶材(cai)企業開(kai)展(zhan)合作，研(yan)(yan)(yan)究(jiu)高溫超(chao)導(dao)(dao)電(dian)(dian)纜(lan)(lan)工程化應用(yong)技術(shu)。去年(nian)，國(guo)網上(shang)(shang)海電(dian)(dian)力(li)正式啟動高溫超(chao)導(dao)(dao)電(dian)(dian)纜(lan)(lan)示范(fan)建設研(yan)(yan)(yan)究(jiu)，為示范(fan)工程建設奠定(ding)重(zhong)要基礎。項(xiang)目前(qian)期，國(guo)網上(shang)(shang)海電(dian)(dian)力(li)攜(xie)手(shou)中國(guo)電(dian)(dian)科院、國(guo)網經研(yan)(yan)(yan)院、上(shang)(shang)海電(dian)(dian)纜(lan)(lan)研(yan)(yan)(yan)究(jiu)所等單位開(kai)展(zhan)技術(shu)攻關，在超(chao)導(dao)(dao)電(dian)(dian)纜(lan)(lan)在城市電(dian)(dian)網中的(de)規劃技術(shu)及(ji)運行方式研(yan)(yan)(yan)究(jiu)、公里級(ji)超(chao)導(dao)(dao)電(dian)(dian)纜(lan)(lan)關鍵技術(shu)研(yan)(yan)(yan)究(jiu)等方面取得創(chuang)新成(cheng)果。
