- Abstract
- Power harmonic detection is the precondition of harmonic suppression. In order to get better harmonic detection results, this paper designs a new harmonic detection instrument based on DSP and ARM. This instrument adopts a modified algorithm that combines FFT with Wavelet Transform, and improves the algorithm of FFT to reduce the required computation. At last validity and feasibility of this algorithm is proved by Matlab simulation. Through the design, this instrument can not only obtain the stable harmonics parameters, but also determine sudden change signals.
