但實際作業(ye)的(de)(de)效(xiao)果怎么(me)樣呢？就目前的(de)(de)諧(xie)波(bo)治理方法來說，主(zhu)要(yao)采用的(de)(de)是有源(yuan)濾波(bo)器和陷波(bo)電路型的(de)(de)無源(yuan)濾波(bo)器。這些濾波(bo)器并聯(lian)安(an)裝在(zai)線(xian)路上，得(de)到的(de)(de)效(xiao)果并不(bu)是很好。相比之下(xia)，在(zai)諧(xie)波(bo)源(yuan)負(fu)載處進行諧(xie)波(bo)治理的(de)(de)效(xiao)果會更加理想一(yi)些，如果在(zai)每個諧(xie)波(bo)源(yuan)負(fu)荷(he)處安(an)裝諧(xie)波(bo)濾波(bo)器，不(bu)僅能夠(gou)獲得(de)較(jiao)好的(de)(de)節電效(xiao)果，而且能夠(gou)保證企(qi)業(ye)內部電網的(de)(de)質量，是值得(de)推廣的(de)(de)一(yi)種方案。
