Transient Fault Line Selection Based on Wavelet Decomposition
Jin Zhiqin · Shanxi Science and Technology · 2012
Based on the theory of wavelet decomposition,the paper proposes the fault line selection based on the sudden change of the transient current α component.According to the characteristics of the wavelet theory handling the signals of sudden changes,the paper further analyzes the transient signals with the help of wavelet theory and selects the fault line based on the comprehensive faults composed of the decomposed wavelet coefficient,which is proved to be efficient by lots of simulation experiments.
