| Abstract: | This paper discusses the subharmonic generation in the electric-network and the problems encountered in harmonic analysis by using FFT.A new state space based on harmonic analysis method is proposed to overcome the shortcomings of FFT.This method first forms the state space model(i.e. state space matrix) then obtains the frequencies,amplitudes and phases of the harmonics composing the distorted wave simultaneously by using matrix conversion.The frequencies harmonics of may not be the integer times of the fundamental frequency. |
