Paper Title:
An Approach for Electrical Inter-Harmonic Analysis Based on W-H Transform
  Abstract

With the non-linear load being used in great quantities, a large number of harmonics and inter-harmonics exist in electrical system. However, lacking of local information, traditional Fourier transform is not suitable for inter-harmonic analysis. In the method of time-frequency analysis, WVD is a joint distribution of energy time-frequency which provides a method for inter-harmonic analysis, but the influence of the cross terms limits application. W-H transform can effectively reduce the impact of cross terms and then extract effective information of inter-harmonic.
