無(wu)(wu)(wu)功(gong)功(gong)率補(bu)償控制(zhi)(zhi)器有(you)三種(zhong)采樣(yang)方(fang)式(shi)，功(gong)率因數(shu)型、無(wu)(wu)(wu)功(gong)功(gong)率型、無(wu)(wu)(wu)功(gong)電流(liu)型。選擇那(nei)一種(zhong)物理控制(zhi)(zhi)方(fang)式(shi)實際上就是對無(wu)(wu)(wu)功(gong)功(gong)率補(bu)償控制(zhi)(zhi)器的選擇。控制(zhi)(zhi)器是無(wu)(wu)(wu)功(gong)補(bu)償裝置的指揮系統，采樣(yang)、運算(suan)、發出投切信號(hao)，參(can)數(shu)設定(ding)、測(ce)量(liang)、元(yuan)件保護等功(gong)能均由補(bu)償控制(zhi)(zhi)器完成(cheng)。

這一技(ji)術的(de)(de)(de)(de)(de)(de)(de)補(bu)償器有下面一些明顯(xian)的(de)(de)(de)(de)(de)(de)(de)優勢(shi)：(1)它能夠利用(yong)可(ke)(ke)變性的(de)(de)(de)(de)(de)(de)(de)電抗器使(shi)得(de)電抗值不(bu)斷地被調整以(yi)達(da)到在功(gong)(gong)率耗用(yong)上的(de)(de)(de)(de)(de)(de)(de)無級目標;(2)利用(yong)這種高(gao)低壓相隔離的(de)(de)(de)(de)(de)(de)(de)技(ji)術，可(ke)(ke)以(yi)在低壓端實施控制的(de)(de)(de)(de)(de)(de)(de)時候，降低系統對電子設備的(de)(de)(de)(de)(de)(de)(de)期望(wang)要求，從而操(cao)作易(yi)于控制，也節約了電力系統的(de)(de)(de)(de)(de)(de)(de)成本;(3)無功(gong)(gong)補(bu)償技(ji)術的(de)(de)(de)(de)(de)(de)(de)裝置所采(cai)用(yong)的(de)(de)(de)(de)(de)(de)(de)是無源(yuan)(yuan)結構(gou)，它跟有源(yuan)(yuan)結構(gou)相比較來說，運行操(cao)作的(de)(de)(de)(de)(de)(de)(de)可(ke)(ke)靠性都比較高(gao)，而且運行所需的(de)(de)(de)(de)(de)(de)(de)費用(yong)偏低。

在電(dian)(dian)(dian)(dian)能質量(liang)問(wen)題的(de)投訴中，90%以(yi)上是由電(dian)(dian)(dian)(dian)壓(ya)暫降(jiang)(jiang)(jiang)引起(qi)(qi)的(de)。由此可(ke)見，電(dian)(dian)(dian)(dian)能質量(liang)的(de)主要問(wen)題是電(dian)(dian)(dian)(dian)壓(ya)暫降(jiang)(jiang)(jiang)問(wen)題。電(dian)(dian)(dian)(dian)壓(ya)暫降(jiang)(jiang)(jiang)是指(zhi)供電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓(ya)有效值短暫降(jiang)(jiang)(jiang)低，隨后恢復正常的(de)供電(dian)(dian)(dian)(dian)現象(xiang)。電(dian)(dian)(dian)(dian)壓(ya)暫降(jiang)(jiang)(jiang)會引起(qi)(qi)敏感(gan)控制器不必要的(de)動作，造成(cheng)包括計算(suan)機系統失靈、自(zi)動化裝置停頓(dun)(dun)或(huo)誤(wu)動、變(bian)頻調(diao)速器停頓(dun)(dun)等;引起(qi)(qi)接觸器脫扣或(huo)低壓(ya)保護啟動，造成(cheng)電(dian)(dian)(dian)(dian)動機、電(dian)(dian)(dian)(dian)梯等停頓(dun)(dun)；引起(qi)(qi)高溫光源(碘鎢燈)熄滅，造成(cheng)公(gong)共(gong)場所失去照明。
