Harmonic and Inter-harmonic Detection Based on Synchrosqueezed Wavelet Transform
To perfectly detect the amplitude for high frequency harmonic and inter-harmonic of small signal,separate the close frequency and improve accuracy of the detection time in dynamic system,a harmonic and inter-harmonic detection method based on synchrosqueezed wavelet transforms (SST) is proposed.In order to evaluate the effectiveness of SST,the simulation experiment was done by MATLAB.Compared with the WT and TT transform,the results show that SST has perfect detection capability for high frequency small signal,and can accurately determine the beginning and end time of transient and well separate the close frequency for the dynamic harmonic and inter-harmonic,so SST is effective and feasible for time-frequency detection and analysis.
