3月30日，經來自(zi)華(hua)中電網(wang)有限公司、清華(hua)大(da)學、湖(hu)南(nan)大(da)學、沈陽變壓器(qi)研究所等單位專家的評審鑒定，在湖(hu)南(nan)懷化并網(wang)運行的國(guo)內(nei)首臺110千伏3萬千伏安(an)磁控(kong)電抗器(qi)損(sun)耗、諧波(bo)等技(ji)術(shu)參數和(he)自(zi)動(dong)調控(kong)性能指標均達到國(guo)際(ji)先進水(shui)平。
目前(qian)，我國主要(yao)采用(yong)(yong)相控(kong)電(dian)抗(kang)器(qi)(qi)，可控(kong)電(dian)抗(kang)器(qi)(qi)的(de)開(kai)發與應用(yong)(yong)尚處(chu)于(yu)起步階段。2006年4月(yue)，湖南省電(dian)力公(gong)司(si)(si)、懷(huai)(huai)化電(dian)業(ye)局(ju)與武(wu)漢大學、青島青波變壓器(qi)(qi)股份有(you)限(xian)公(gong)司(si)(si)聯合進行110千伏(fu)可控(kong)電(dian)抗(kang)器(qi)(qi)的(de)開(kai)發與應用(yong)(yong)研究(jiu)。去年6月(yue)17日，國內首臺110千伏(fu)磁(ci)控(kong)電(dian)抗(kang)器(qi)(qi)在懷(huai)(huai)化電(dian)業(ye)局(ju)220千伏(fu)田(tian)家變完成安(an)裝(zhuang)調試并一次投運成功(gong)。
110千(qian)伏(fu)磁控(kong)(kong)電(dian)(dian)(dian)抗(kang)器在(zai)保持相控(kong)(kong)電(dian)(dian)(dian)抗(kang)器優點(dian)的(de)同時，具有容量連續可(ke)(ke)調、可(ke)(ke)靠(kao)性高(gao)、免維護、產(chan)生諧波小等優點(dian)，可(ke)(ke)直接接入(ru)高(gao)壓(ya)(ya)(ya)電(dian)(dian)(dian)網。在(zai)電(dian)(dian)(dian)網中采(cai)用這種可(ke)(ke)控(kong)(kong)電(dian)(dian)(dian)抗(kang)器，能極大(da)改善電(dian)(dian)(dian)網的(de)無(wu)功(gong)潮流和電(dian)(dian)(dian)壓(ya)(ya)(ya)自動(dong)控(kong)(kong)制(zhi)能力(li)，大(da)幅度提高(gao)輸電(dian)(dian)(dian)能力(li)，對電(dian)(dian)(dian)網安全穩定運行起到(dao)重要作用，同時還降(jiang)低了固定投資，是高(gao)壓(ya)(ya)(ya)和超高(gao)壓(ya)(ya)(ya)電(dian)(dian)(dian)網理想的(de)動(dong)態無(wu)功(gong)補償和電(dian)(dian)(dian)壓(ya)(ya)(ya)調節(jie)設備(bei)。
