摘要
谐波检测是有源电力滤波器实时补偿谐波的关键,检测谐波的实际是通过某种方法提取出基波。所以本文主要研究基波提取法即传统的ip-iq法、平均值法和正序法等三种方法。在研究理论的基础上对三种方法进行MATLAB仿真建模和比较分析,并着重比较三种方法提取基波的实时性,比较结果表明,实时性最好的是平均值法,其次是传统的ip-iq法,最差的是正序法。
The harmonic detection is the key of APF real-time compensation, and the fundamental wave extraction is the truly reality of the harmonic detections. This paper mainly researches on three wave extraction methods as the traditional ip - iq, the average method, and the positive sequence extraction. Researching on three kinds of methods for MATLAB simulation modeling and comparative analysis that based on their theory, and putting emphasis on comparison of fundmental wave extraction real-time, comparison results show that the the best performance is average method, followed by the traditional ip - iq method, the worst is the positive sequence method.
