Arc Fault Recognition Method Based on Phase Space Reconstruction and Fractal Theory
Abstract:
A method of recognize arc fault based on phase space reconstruction and fractal theory is presented in this paper.In order to obtain the current wave under the conditions of different arc faults, the experiment platform is built according to UL1699 standard so as to sample the current wave of arc fault by the digital oscilloscope. Meanwhile the current wave of some electrical equipment with the normal operation are also sampled. The phase space track chart are obtained by the method of phase space reconstruction theory, and the algorithm about extracting characteristic quantity of arc fault current is presented based on the fractal theory. By simulating using MATLAB software, the box-count dimension of the current phase space track charts for arc fault and the some electrical equipment with normal operation are calculated, its result prove this algorithm effective and feasible.
