摘　　要：传统的i_(p)-i_(q)谐波检测中单纯使用低通滤波器(LPF)很难同时满足检测精度高和滤波效果优的需求。本文提出了改进的谐波检测方法,将传统的低通滤波器和积分均值滤波器串联使用,提高了响应速度和精度。此外,还引入了反馈环路来补偿LPF造成的延迟,通过对改进的谐波检测方法的理论分析和MATLAB环境下的仿真,证明了改进方法的有效性。In traditional i_(p)-i_(q) harmonic detection,it is difficult to meet the requirements of high detection accuracy and excellent filtering effect by using only LPF.In this paper,an improved harmonic detection method is proposed,in which the traditional low-pass filter and integral mean filter are used in series to improve the response speed and accuracy.In addition,a feedback loop is introduced to compensate the delay caused by LPF.The effectiveness of the improved harmonic detection method is proved by theoretical analysis and simulation in MATLAB environment.
