Abstract:In this paper , in order to detect the harmonic of Gird accurately, the harmonic detection of Grid basing on Modified Multi-resolution analysis and Adaptive analysis and Fourier analysis is presented and is used in field of harmonic detection of Grid. Validation results show that : when the Grid includes harmonic , this program could locate the harmonic accurately and detect the harmonic. It is good at of detecting about the signal of unstable .In the end, it achieve the goals of eliminating harmonic of Grid and supplying stable electricity.
