FFT加窗插值修正算法可以较好地提高电力系统

谐波测量的准确度 ,减少由于栅栏效应带来的误差.但

该算法比较复杂 ,编程实现比较困难 ,而Matlab有强大

的数字信号处理功能 ,有专门用于快速傅立叶变换的

FFT函数和良好的图形显示功能.因此用 Matlab 实现

加窗插值算法 ,降低了算法实现的复杂度 ,无论是在仿

真方面还是在实用上都能达到事半功倍的效果-FFT and window interpolation correction algorithm can better improve the power system

Harmonic measurement accuracy, reduce the error caused by the fence effect. But

The algorithm is more complex, more difficult by programming, and Matlab has powerful

Digital signal processing function, specially for the fast Fourier transform

FFT function and good graphic display function. So the Matlab

Add window interpolation algorithm, reduce the complexity of algorithm implementation, whether in the imitation

True aspect and practical can achieve twice the result with half the effort
