8月29日，全(quan)國首個智能柔(rou)性(xing)直流配電網(wang)(wang)示范工(gong)(gong)程在浙(zhe)江杭州江東新城順利通過(guo)試運(yun)行(xing)(xing)考驗，經功能升級后(hou)正(zheng)(zheng)式投(tou)入運(yun)行(xing)(xing)。據悉，該工(gong)(gong)程的建成(cheng)實(shi)現了配電網(wang)(wang)從傳(chuan)統放射型向多端(duan)互聯網(wang)(wang)絡轉變，可在百毫秒內快速(su)隔離(li)系(xi)統故障并恢復正(zheng)(zheng)常運(yun)行(xing)(xing)，大幅(fu)提(ti)升杭州電網(wang)(wang)的安全(quan)可靠性(xing)。
2016年(nian)，杭州(zhou)供電(dian)(dian)公司(si)為打造可(ke)靠(kao)性(xing)高、互動友(you)好、經(jing)濟高效的一(yi)流(liu)現代(dai)化配(pei)(pei)電(dian)(dian)網(wang)，率先啟動智(zhi)能柔性(xing)直流(liu)配(pei)(pei)電(dian)(dian)網(wang)技術研究工作(zuo)。2017年(nian)10月(yue)，智(zhi)能柔性(xing)直流(liu)配(pei)(pei)電(dian)(dian)網(wang)示(shi)范項目正式開工建設，工程額定電(dian)(dian)壓(ya)±10千伏，總換流(liu)容量(liang)3萬(wan)千瓦。
杭州江(jiang)東新城(cheng)智能(neng)柔性直流配電(dian)(dian)(dian)(dian)網工(gong)程(cheng)通過(guo)采用(yong)(yong)區(qu)域協調(diao)控制、故障快速定位及隔離保護(hu)等(deng)(deng)技(ji)術，實現多路電(dian)(dian)(dian)(dian)源(yuan)(yuan)同時(shi)為用(yong)(yong)戶供(gong)電(dian)(dian)(dian)(dian)，確保單(dan)路電(dian)(dian)(dian)(dian)源(yuan)(yuan)故障情況下(xia)負荷安全(quan)經濟轉移。同時(shi)，該工(gong)程(cheng)可采用(yong)(yong)直流供(gong)電(dian)(dian)(dian)(dian)模式，在不影響電(dian)(dian)(dian)(dian)網電(dian)(dian)(dian)(dian)能(neng)質(zhi)量的情況下(xia)，為10千(qian)米(mi)外用(yong)(yong)戶提(ti)供(gong)供(gong)電(dian)(dian)(dian)(dian)服(fu)務，極大(da)優化了(le)杭州電(dian)(dian)(dian)(dian)網的供(gong)電(dian)(dian)(dian)(dian)能(neng)力(li)。工(gong)程(cheng)還具備電(dian)(dian)(dian)(dian)動汽車充換電(dian)(dian)(dian)(dian)設(she)施等(deng)(deng)多元化負荷、儲(chu)能(neng)和(he)分布式電(dian)(dian)(dian)(dian)源(yuan)(yuan)無障礙接入的條件，助推能(neng)源(yuan)(yuan)互聯網發展。
