摘　　要：电力谐波的危害不容忽视,我们根据谐波结果分析探讨并采取相应防护措施是极为重要的。本文在现代谱估计方法的基础上详细叙述了多重信号分类方法的理论,提出采用MUSIC算法恢复谐波。仿真结果表明,本方法对于恢复谐波具有良好的效果。The harm of power harmonics can not be ignored, according to the analysis of harmonic results and take ap- propriate protective measures is very important. Based on modern spectral estimation method based on the described in detail the theory of multiple signal classification method is proposed using music algorithm for harmonic retrieval. The simulation results show that, this method has good effect of harmonic retrieval.
