近日，由華中科技大(da)學聯合(he)國內(nei)優勢單位，歷時10年，成功研制的國內(nei)首套移(yi)動組(zu)件式直接(jie)冷卻高(gao)溫超導磁儲能(neng)系統在湖北秭歸(gui)縣(xian)老虎口水電站順利完成全部現場試驗，各項(xiang)試驗結(jie)果(guo)均達到預期目標。
此(ci)次試(shi)驗(yan)(yan)是(shi)華(hua)中(zhong)(zhong)(zhong)科技大學(xue)和(he)(he)國(guo)(guo)家(jia)電(dian)(dian)網(wang)(wang)湖北公(gong)司聯合承擔(dan)的(de)(de)國(guo)(guo)家(jia)863計劃項目(mu)的(de)(de)重要研究內容之一，試(shi)驗(yan)(yan)歷(li)時12天(tian)。移動組件式直接冷卻(que)高溫超(chao)導磁儲(chu)能(neng)系統(tong)的(de)(de)主要部件都安放在一個(ge)(ge)特制的(de)(de)集裝箱(xiang)中(zhong)(zhong)(zhong)，集裝箱(xiang)可(ke)用卡車(che)運輸，可(ke)以根(gen)據需要運送安放到合適的(de)(de)位置，接入電(dian)(dian)網(wang)(wang)進行功率調(diao)控。該移動組件式高溫超(chao)導磁儲(chu)能(neng)系統(tong)從武漢運抵秭歸縣老虎口水電(dian)(dian)站，經過了(le)數百(bai)公(gong)里各種(zhong)等級公(gong)路；整個(ge)(ge)試(shi)驗(yan)(yan)過程中(zhong)(zhong)(zhong)系統(tong)均(jun)露天(tian)放置，經歷(li)了(le)雷雨、大風、酷(ku)熱(re)等各種(zhong)天(tian)氣的(de)(de)考驗(yan)(yan)；接入電(dian)(dian)網(wang)(wang)后，又經過了(le)電(dian)(dian)網(wang)(wang)電(dian)(dian)壓波動和(he)(he)電(dian)(dian)網(wang)(wang)因雷擊多(duo)次停電(dian)(dian)等考驗(yan)(yan)，在上述各種(zhong)條件下，儲(chu)能(neng)系統(tong)均(jun)能(neng)正常工作運行。
該(gai)系(xi)(xi)統(tong)(tong)由(you)(you)儲(chu)能(neng)(neng)磁(ci)(ci)體、變流器及監控(kong)裝置組成的(de)(de)(de)一(yi)種多功能(neng)(neng)能(neng)(neng)量(liang)管理裝置，具有(you)提高電(dian)(dian)力(li)系(xi)(xi)統(tong)(tong)穩定性、改善供電(dian)(dian)質量(liang)的(de)(de)(de)特(te)點，可(ke)作為(wei)不間(jian)斷電(dian)(dian)源。該(gai)系(xi)(xi)統(tong)(tong)使(shi)用(yong)由(you)(you)國產高溫超導(dao)帶材(cai)繞制(zhi)而成的(de)(de)(de)儲(chu)能(neng)(neng)磁(ci)(ci)體，采用(yong)制(zhi)冷機直接冷卻，無需使(shi)用(yong)液(ye)氮、液(ye)氦等冷卻方式(shi)，將(jiang)有(you)助于今后根(gen)據電(dian)(dian)力(li)系(xi)(xi)統(tong)(tong)和(he)用(yong)戶的(de)(de)(de)需求(qiu)靈活選擇安裝地點。變流器采用(yong)四重模塊結構及移相控(kong)制(zhi)方式(shi)，以(yi)增(zeng)大功率、減(jian)少諧波，實現儲(chu)能(neng)(neng)磁(ci)(ci)體和(he)電(dian)(dian)力(li)系(xi)(xi)統(tong)(tong)間(jian)的(de)(de)(de)四象限的(de)(de)(de)有(you)功功率與(yu)無功功率交(jiao)換。隨著電(dian)(dian)力(li)需求(qiu)的(de)(de)(de)快速增(zeng)長，超導(dao)磁(ci)(ci)儲(chu)能(neng)(neng)系(xi)(xi)統(tong)(tong)有(you)望在未來電(dian)(dian)力(li)系(xi)(xi)統(tong)(tong)中廣泛(fan)應用(yong)。
據悉，該項成果(guo)填補(bu)了(le)國(guo)內在(zai)超導研究領域的空(kong)白，標志著(zhu)我國(guo)在(zai)直接冷卻高溫超導磁儲能實用技術方面又向前邁進了(le)一步。
