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 analysis algorithm is proposed on the basis of the windowed interpolation and the MUSIC method． It is shown by matlab simulation that the new method enjoys higher frequency resolution and is more precise than traditional ones．
