摘要
对于电网中的谐波抑制方法是无源滤波器和有源滤波器。无源滤波器根据交流电路串、并联谐振的原理,使高频成分流到地线而消除对电源的污染。有源滤波器采用补偿谐波电流的方式消除非线性负载对电源的污染。上述方式是以牺牲谐波电能为代价达到谐波抑制的目的。文章以无源滤波器滤波为例,提出使用多抽头变压器提取谐波电能的方法。经过实际测试,证明所提出的方法简便,可行性高,节能效果明显。
Passive and active power filter is used in harmonic suppression.High frequency harmonic of passive filter flows into ground to eliminate harmonic pollution of power based on AC circuit series,parallel resonance.It adopts harmonic current compensation to eliminate power pollution of non-linear load in active power filter.The harmonic suppression is at the expense of harmonic energy loss.The multi-tap transformer is introduced in this paper to extract harmonic energy as passive filter.After actual test,the proposed method is simple,feasible and of obvious energy-saving effect.
