【Abstract】 This paper introduced the basic principle and characteristics of wavelet transform and illustrated how wavelet transform was used to analyze the important fault information in the curved line of power load by MATLAB with an example.MATLAB wavelet tool box was used to achieve detection and wavelet was used to rebuild and recover the lost data,which proves the wavelet transform can be efficiently used in the field of monitoring and fault diagnosis for power load state.更多还原
