AN ELECTRIC POWER SYSTEM FAULT TRANSIENT DATA COMPRESSION METHOD BASED ON OPTIMAL WAVELET

Based on the declaration the waveletconstruc-tion method and wavelet decomposition theory ofmultiresolution analysis. Combined the feather of power fault transient. A wavelet optimal construction method based onminimizing the 2-norm of discrete wavelet decompositionapproximation is studied. computation indicate that this method applied in the compression of power system fault transient data will increase the compression ratio and decrease thereconstruction error.
