摘要
谐波检测的准确与快速决定了有源电力滤波器的补偿效果,阐述了Park变换的基本思想与运算规律。以电压谐波为研究对象,采用了基于Park变化的检测方法,设计了谐波检测过程中的低通滤波器。用Multisim仿真软件对这种检测方法进行了仿真,仿真结果表明该方法的准确性、快速性能够满足要求,具有一定的合理性。
The compensation effect of active power filter is determined by the accuracy and rapidity of harmonic wave detection.Basic idea and arithmetic rules of Park transformation is illustrated.Detection method based on Park transformation is applied to analyze the harmonic wave of voltage signal,low-pass filter is designed for the detection process.This detection method is simulated by Multisim simulation software and result shows the accuracy and rapidity can meet the demand and is reasonable as well.
