目(mu)前國內市場上被宣傳(chuan)SVC的(de)(de)產品(pin)主(zhu)工(gong)是晶(jing)(jing)閘(zha)管控(kong)制(zhi)電(dian)抗器(TCR)和晶(jing)(jing)閘(zha)管投切電(dian)容器(TSC)。TCR的(de)(de)基本結構包括一(yi)(yi)組固(gu)定并聯(lian)(lian)連接(jie)在線(xian)路中(zhong)的(de)(de)電(dian)容器和一(yi)(yi)組并聯(lian)(lian)連接(jie)在線(xian)路中(zhong)用晶(jing)(jing)閘(zha)管控(kong)制(zhi)的(de)(de)電(dian)抗器，通常將(jiang)電(dian)抗器的(de)(de)容量設計成與電(dian)容器一(yi)(yi)樣。

智能建筑中濾波補償模組改造方案

早期(qi)的(de)(de)無(wu)功補(bu)償(chang)電(dian)容器自動(dong)化(hua)程(cheng)(cheng)度偏低，不能(neng)(neng)對(dui)電(dian)網運(yun)(yun)行(xing)(xing)參數的(de)(de)變化(hua)進(jin)行(xing)(xing)判(pan)斷(duan)，需要運(yun)(yun)行(xing)(xing)人員在運(yun)(yun)行(xing)(xing)過(guo)程(cheng)(cheng)中進(jin)行(xing)(xing)投切(qie)操作(zuo)(zuo)。當網絡(luo)變化(hua)頻次高時(shi)操作(zuo)(zuo)較(jiao)頻繁，運(yun)(yun)行(xing)(xing)人員會感到吃(chi)力，增(zeng)加(jia)了工作(zuo)(zuo)量。隨著計算機技(ji)術的(de)(de)飛速發展(zhan)，現在的(de)(de)無(wu)功補(bu)償(chang)裝置(zhi)成功地采(cai)用了微(wei)機模(mo)塊進(jin)行(xing)(xing)裝置(zhi)的(de)(de)運(yun)(yun)行(xing)(xing)管理，自動(dong)化(hua)程(cheng)(cheng)度比較(jiao)高，能(neng)(neng)及時(shi)判(pan)斷(duan)電(dian)網參數的(de)(de)變化(hua)，進(jin)行(xing)(xing)合(he)理的(de)(de)自動(dong)投切(qie)，不會增(zeng)加(jia)運(yun)(yun)行(xing)(xing)人員的(de)(de)工作(zuo)(zuo)量，自動(dong)化(hua)水平已(yi)達到電(dian)網運(yun)(yun)行(xing)(xing)的(de)(de)要求。
