Harmonic detection method based on parameter spectrum
To reduce noise interference of Prony for extracting harmonic parameters, a harmonic analysis method integrating local mean decomposition (ELMD) - singular value decomposition (SVD) - Prony (ELMD-SVD Prony) is proposed. The noise component is removed while the effective component is retained. The Hankel matrix is reconstructed in phase space for the effective component, and singular value decomposition is used for secondary denoising and reconstruction. Finally, the reconstructed signal is superimposed with the ELMD residue to obtain the denoised harmonic signal.
