Research on the Application of Wavelet Analysis in Fault Detection

Abstract:

For the purpose of fast fault diagnosis and fault time point location, wavelet transform was used in the fault diagnosis in this paper, due to its singularity of the wavelet transform and multi-resolution properties, and it is verified the simulation examples, which illustrates different wavelet coefficients have different effect on the detection of mutation signal. Finally we obtained a general method of wavelet type selection.
