Abstract:Based on basic theory of wavelet analysis and according to wave characteristics of fault phase's current when power system was shorted, the paper introduced how to use mutant points of high frequency component after decomposition and reconstruction of wavelet to detect whether fault had happened. The simulation results showed the effectiveness of this algorithm, and microprocessor based protection circuit based on the algorithms in documents 1] was put forward. Finally, eliminating noises method of fault signal was analyzed.
Keywords:power system  fault  microprocessor  relay protection  wavelet transform  simulation
