“投切振蕩”現象的發生主要與電容器分組數和容量、控制器的功率因數上、下限范圍設置、調節時間只種因素有關，縮小電容器的容量加大分組數可以解決這個問題，但由于現場的位置限制需要新增電容柜，原來的配電柜需改造投資，而且影響生產，不是最理想方案。我們根據該廠的負荷特性，發現該廠晚上的用電負荷主要是照明設備，而目前使用的螢光燈具基本上都裝了補償電容器，而白熾燈功率因數為1，總的功率因數Cos滬并不太低，故可不投人補償電容器，于是可以采用提高欠電流封鎖值的辦法解決“投切振蕩”問題。經調整后，該廠再也沒出現過電容器組反復投切的現象，從而確保了無功功率自動補償裝置的正常工作。
當然提高欠電流封鎖值是**無功功率自動補償低負荷電容器投切振蕩的一種**方法。但調整值應適當且需通過計算，如欠電流封鎖值調得太高，會影響低負荷時的無功功率補償效果，適當調整投切門限對**振蕩有一定作用。目前，國內還有另一類型的控制器在使用，如廣西桂林象山電子控制器廠生產的JKWD型無功功率自動補償器，該控制器不是以功率因數值作為電容器組的投切門限，而是選擇了無功功率值作為控制量，投人門限為與1組電容器組相等的感性無功功率值，切除門限為0.4組電容器容t的容性無功功率值，使用這種類型的無功功率自動控制器就能保證避免電容器組“投切振蕩”問題。
