目前國內市(shi)場上被宣傳SVC的產品主工(gong)是(shi)晶(jing)閘(zha)管控(kong)制(zhi)電(dian)抗器(qi)(qi)(qi)(TCR)和晶(jing)閘(zha)管投切電(dian)容(rong)器(qi)(qi)(qi)(TSC)。TCR的基(ji)本結構包括(kuo)一(yi)組(zu)固定并(bing)聯連接在線路中(zhong)(zhong)的電(dian)容(rong)器(qi)(qi)(qi)和一(yi)組(zu)并(bing)聯連接在線路中(zhong)(zhong)用晶(jing)閘(zha)管控(kong)制(zhi)的電(dian)抗器(qi)(qi)(qi)，通常將電(dian)抗器(qi)(qi)(qi)的容(rong)量(liang)設計成與電(dian)容(rong)器(qi)(qi)(qi)一(yi)樣。

智能建筑中(zhong)濾波補償模組改(gai)造方案(an)

早期的無功補償(chang)電(dian)(dian)(dian)容器(qi)自(zi)動(dong)(dong)(dong)化(hua)(hua)程度偏低，不能對電(dian)(dian)(dian)網運行(xing)參數的變化(hua)(hua)進(jin)(jin)(jin)行(xing)判斷，需要運行(xing)人(ren)員(yuan)在運行(xing)過程中進(jin)(jin)(jin)行(xing)投切(qie)操作(zuo)。當網絡變化(hua)(hua)頻次高(gao)時操作(zuo)較(jiao)(jiao)頻繁，運行(xing)人(ren)員(yuan)會感到吃力，增(zeng)加了(le)工作(zuo)量。隨(sui)著(zhu)計(ji)算機(ji)(ji)技術的飛速發展，現(xian)在的無功補償(chang)裝置成(cheng)功地采用了(le)微機(ji)(ji)模塊進(jin)(jin)(jin)行(xing)裝置的運行(xing)管(guan)理(li)，自(zi)動(dong)(dong)(dong)化(hua)(hua)程度比較(jiao)(jiao)高(gao)，能及時判斷電(dian)(dian)(dian)網參數的變化(hua)(hua)，進(jin)(jin)(jin)行(xing)合理(li)的自(zi)動(dong)(dong)(dong)投切(qie)，不會增(zeng)加運行(xing)人(ren)員(yuan)的工作(zuo)量，自(zi)動(dong)(dong)(dong)化(hua)(hua)水平已達(da)到電(dian)(dian)(dian)網運行(xing)的要求。

在交流(liu)電(dian)(dian)(dian)路中(zhong)，電(dian)(dian)(dian)阻(zu)、電(dian)(dian)(dian)感、電(dian)(dian)(dian)容元件的電(dian)(dian)(dian)壓(ya)、電(dian)(dian)(dian)流(liu)的相(xiang)位(wei)特點為(wei)在純電(dian)(dian)(dian)阻(zu)電(dian)(dian)(dian)路中(zhong)，電(dian)(dian)(dian)流(liu)與電(dian)(dian)(dian)壓(ya)同相(xiang)位(wei)；在純電(dian)(dian)(dian)容電(dian)(dian)(dian)路中(zhong)電(dian)(dian)(dian)流(liu)超(chao)前電(dian)(dian)(dian)壓(ya)90°；在純電(dian)(dian)(dian)感電(dian)(dian)(dian)路中(zhong)電(dian)(dian)(dian)流(liu)滯后電(dian)(dian)(dian)壓(ya)90°。從供電(dian)(dian)(dian)角(jiao)度，理(li)想的負(fu)載是P與S相(xiang)等，功(gong)率因數cosφ為(wei)1。
