Abstract
Intelligence algorithm benefits most of diagnosis and repair working. Fault location in distribution power system is vital for the electronic power supply constantly. A novel fault location method based on ANN is used for complex power system. The amplitude of transient initial traveling wave is used to select the measuring points which form the fault scope. The arrival time of zero mode and aerial mode traveling wave are calibrated by wavelet transform. In each level of detail coefficient, the time difference is different, which is relate to the fault distance and used for the input of ANN. Then, the accuracy fault location can be obtained in fault scope using ANN. PSCAD/EMTDC is used to verify the effectiveness of proposed method.
