Speech Title: A VMD Harmonic Detection Method Based on Improved SVD Denoising

Abstract: Harmonic detection is an important problem in power system, but the accuracy of harmonic detection is affected by the mixed noise of signal to be detected. In order to suppress the influence of noise, this paper uses improved singular value decomposition to de-noise the detected signal, and then uses VMD decomposition and improved energy operator to accurately detect each harmonic component. The simulation results show that the harmonic detection algorithm can accurately identify the information characteristics of each harmonic and inter-harmonic, and has the advantages of high accuracy and small error.
