Fault Line Selection of Power System Based on Dual-Tree Complex Wavelet

Abstract:

Through analysis of various concept methods, developing route selection device based on double tree complex wavelet and transient energy, use the method based on transient component can improve line selection accuracy effectively. sensitivity and directional selectivity can improved by using dual tree complex wavelet transform than using discrete wavelet translation, the method can’t infect by the line of power system and the condition of the fault line. The simulation results show that by using the dual tree complex wavelet analysis in suitable scale can select the fault line correctly.
