3月30日，經來自華(hua)中(zhong)電(dian)網(wang)有限公司、清華(hua)大學、湖(hu)南大學、沈陽變壓器研究所等單(dan)位專家的評審鑒定，在湖(hu)南懷化并網(wang)運行的國(guo)內首臺110千伏3萬(wan)千伏安磁控電(dian)抗器損耗、諧(xie)波(bo)等技術參數和自動調控性能指(zhi)標均達到國(guo)際(ji)先(xian)進水平。
目前，我國主要采用相控(kong)電(dian)抗器(qi)，可控(kong)電(dian)抗器(qi)的開發與(yu)應用尚處于(yu)起步階段。2006年4月，湖南省電(dian)力公(gong)司、懷化電(dian)業局(ju)與(yu)武(wu)漢(han)大學、青島青波變壓器(qi)股份有限(xian)公(gong)司聯合(he)進行110千(qian)(qian)伏(fu)可控(kong)電(dian)抗器(qi)的開發與(yu)應用研究。去年6月17日，國內首(shou)臺110千(qian)(qian)伏(fu)磁控(kong)電(dian)抗器(qi)在(zai)懷化電(dian)業局(ju)220千(qian)(qian)伏(fu)田(tian)家變完(wan)成安裝調(diao)試并(bing)一(yi)次(ci)投運成功(gong)。
110千伏磁控(kong)電(dian)(dian)(dian)抗(kang)器(qi)在(zai)保持相(xiang)控(kong)電(dian)(dian)(dian)抗(kang)器(qi)優(you)點的(de)(de)同時(shi)，具有容量(liang)連續可(ke)調、可(ke)靠性高、免維護、產(chan)生諧波(bo)小等優(you)點，可(ke)直接接入(ru)高壓(ya)電(dian)(dian)(dian)網(wang)。在(zai)電(dian)(dian)(dian)網(wang)中采(cai)用(yong)這種可(ke)控(kong)電(dian)(dian)(dian)抗(kang)器(qi)，能極大改善電(dian)(dian)(dian)網(wang)的(de)(de)無功(gong)潮流和電(dian)(dian)(dian)壓(ya)自動(dong)控(kong)制(zhi)能力，大幅度提高輸電(dian)(dian)(dian)能力，對電(dian)(dian)(dian)網(wang)安全穩(wen)定(ding)運行起到重要作(zuo)用(yong)，同時(shi)還降低了固定(ding)投資，是高壓(ya)和超高壓(ya)電(dian)(dian)(dian)網(wang)理(li)想的(de)(de)動(dong)態無功(gong)補償(chang)和電(dian)(dian)(dian)壓(ya)調節設備。
