中衛電網填補相關領(ling)域(yu)空(kong)白——
首(shou)次(ci)串(chuan)聯(lian)電容補償(chang)裝置人工短路試驗成功
日前(qian)，海原110千(qian)伏變電站新海線線路串(chuan)聯電容補(bu)償(chang)裝置人工短路試驗圓滿(man)成功，期間設備安全穩定，達到(dao)了(le)試驗預期要求。該項目(mu)實(shi)現了(le)多項技術上(shang)的創新，填(tian)補(bu)了(le)寧夏電網(wang)串(chuan)聯電容補(bu)償(chang)技術領域的空(kong)白。
由(you)于大功(gong)率遠距(ju)離輸電(dian)(dian)(dian)(dian)(dian)等(deng)原(yuan)(yuan)因，110千伏(fu)海(hai)原(yuan)(yuan)變(bian)(bian)電(dian)(dian)(dian)(dian)(dian)站(zhan)35千伏(fu)母線(xian)實測電(dian)(dian)(dian)(dian)(dian)壓質量(liang)嚴重超(chao)標。為從(cong)根本上解決(jue)該問題(ti)，中衛(wei)供電(dian)(dian)(dian)(dian)(dian)局經多方(fang)驗證(zheng)，研究確定了線(xian)路(lu)(lu)串聯(lian)電(dian)(dian)(dian)(dian)(dian)壓補(bu)償(chang)裝(zhuang)置方(fang)案，通過在海(hai)原(yuan)(yuan)變(bian)(bian)電(dian)(dian)(dian)(dian)(dian)源(yuan)進線(xian)110千伏(fu)新海(hai)線(xian)線(xian)路(lu)(lu)末端(duan)串聯(lian)該電(dian)(dian)(dian)(dian)(dian)容補(bu)償(chang)裝(zhuang)置達到補(bu)償(chang)電(dian)(dian)(dian)(dian)(dian)壓的(de)目(mu)的(de)。此(ci)次人工短路(lu)(lu)試驗正是為了考驗該裝(zhuang)置在發生(sheng)短路(lu)(lu)時能否可靠退出(chu)，是串聯(lian)電(dian)(dian)(dian)(dian)(dian)容補(bu)償(chang)裝(zhuang)置能否可靠運行的(de)關(guan)鍵。此(ci)次試驗的(de)成功(gong)，將有效解決(jue)長期困擾(rao)海(hai)原(yuan)(yuan)地(di)區的(de)電(dian)(dian)(dian)(dian)(dian)壓質量(liang)不合格問題(ti)，提升供電(dian)(dian)(dian)(dian)(dian)可靠性。
