Detection Methods of Interharmonics Parameters Based on DFT Filter Banks

Quanyi Jin

Abstract

There are a large number of interharmonics in electric power system. But if FFT algorithm is directly used for interharmonic analysis, it exists spectrum leakage and hurdle effect. This paper presents using multi-sample rate digital signal processing technology to realize narrowb and low-pass filter, on this basis, using the DFT filter banks to detect interharmonic frequency and amplitude. The simulation results show, the new algorithm has high detection precision.
