基于全相位谱分析的相位测量原理及其应用
Principle of Phase Measurement and Its Application Based on All-Phase Spectral Analysis
摘要
Abstract
To study the properties of the phase spectrum of all-phase FFT(apFFT for short)and extend its application fields,this paper presents the phase measurement mechanism based On apFFT from the phase spectrum in polar coordinate,vector analysis,matrix analysis,and simulation,etc.And apFFT properties of the phase measurement without correcting spectrum and the restraining spectral leakage are analyzed.The experiment shows that the variance of the phase measured by apFFT is at least 2/3 lower than that of FFT with the same order,so "all phase meter"is expected to be applied in the device fault detection,the harmonic analysis of the power system,GPS navigation and positioning,etc.关键词
