摘　　要：电力系统中非线性负载使用逐渐增加,电力系统中谐波问题越来越严重,电能计量和谐波治理都法需要实时、准确的检测出基波。本文基于Kalman滤波算法对系统谐波进行滤波,从而获得所需要的基波分量。最后,通过MATLAB软件仿真验证该方法的可行性。The use of non-linear loads in power systems is gradually increasing,and the problem of harmonics in power systems is becoming more and more serious,both power measurement and harmonic control methods need to detect the fundamental waves in real time and accurately.In this paper,the harmonics of the system are filtered based on the Kalman filter algorithm,to obtain the required fundamental components.Finally,the feasibility of the method is verified by MATLAB software simulation.

关 键 词：基波检测 KALMAN滤波 谐波滤除
