Abstract
Detecting interharmonics for flicker troubleshooting is highly desirable. Whereas these interharmonics are close to harmonic or fundamental component, it is always swamped by the main-lobe of harmonic nearby if the harmonic amplitude is much bigger than interharmonic amplitude, and vice versa. In this paper, an improved interharmonic analy- sis algorithm is proposed on the basis of the windowed interpolation and the MUSIC method. It is shown by matlab simu- lation that the new method enioys higher frequency resolution and is more nrecise than traditional anag_关键词
