3月30日，經來(lai)自華中電(dian)網有限公司、清華大(da)學、湖南大(da)學、沈陽變壓器研究所(suo)等單位專家的評審(shen)鑒定，在(zai)湖南懷(huai)化并網運行的國內首臺(tai)110千(qian)伏3萬千(qian)伏安磁控電(dian)抗器損耗(hao)、諧波等技(ji)術參數和自動調控性能指標均達到國際先進水平。
目(mu)前，我國(guo)主要(yao)采用相控(kong)電抗(kang)器，可控(kong)電抗(kang)器的開發(fa)與應用尚處于起步(bu)階段。2006年4月(yue)，湖南省電力公司(si)、懷(huai)化電業(ye)局與武漢(han)大學、青(qing)島青(qing)波變(bian)壓器股份有(you)限公司(si)聯合進(jin)行110千伏(fu)(fu)可控(kong)電抗(kang)器的開發(fa)與應用研究。去年6月(yue)17日，國(guo)內首臺110千伏(fu)(fu)磁控(kong)電抗(kang)器在懷(huai)化電業(ye)局220千伏(fu)(fu)田家變(bian)完成(cheng)安裝調試并一次投(tou)運(yun)成(cheng)功。
110千伏磁控(kong)(kong)電(dian)(dian)(dian)(dian)抗(kang)器(qi)在保(bao)持(chi)相控(kong)(kong)電(dian)(dian)(dian)(dian)抗(kang)器(qi)優點(dian)的(de)同時(shi)，具有容量連(lian)續可調(diao)、可靠(kao)性高、免維(wei)護、產生諧波小(xiao)等優點(dian)，可直接接入高壓電(dian)(dian)(dian)(dian)網(wang)。在電(dian)(dian)(dian)(dian)網(wang)中(zhong)采用這(zhe)種可控(kong)(kong)電(dian)(dian)(dian)(dian)抗(kang)器(qi)，能極大改善(shan)電(dian)(dian)(dian)(dian)網(wang)的(de)無功(gong)潮流和電(dian)(dian)(dian)(dian)壓自動(dong)控(kong)(kong)制能力，大幅(fu)度提高輸電(dian)(dian)(dian)(dian)能力，對(dui)電(dian)(dian)(dian)(dian)網(wang)安全穩定運行起到(dao)重要作用，同時(shi)還降低了固定投資，是(shi)高壓和超高壓電(dian)(dian)(dian)(dian)網(wang)理想(xiang)的(de)動(dong)態無功(gong)補(bu)償和電(dian)(dian)(dian)(dian)壓調(diao)節設備。
