一种基于加窗的插值FFT重构Hilbert变换方法
A Transforming Method of Hilbert Based on the Windowed Interpolation FFT Reconstruction
摘要
Abstract
This paper presents a windowed interpolation FFT-based reconstruction algorithm for the Hilhert transform to measure the reactive power. The method, by inverse and discrete Fourier, can accurately shift all the harmonics by 90 °. And by using the FFT algorithm of Jia Haiming window, it can calculate each harmonic frequency, phase, and amplitude calculation. It overcomes the impact of spectral leakage and eliminates its measurement error. Simulation results show that the method has high measurement accuracy.关键词
