- In order to accurately detect single-phase resonant network grounding fault, puts forward a fault line selection method based on fault transient amplitude measurement. Through the analysis of fault feeder modulus transform, after occurrence of a fault and normal feeder, using wavelet modulus maxima characteristics of current zero mode, obtained initial current wavelet modulus maxima of law. Combining the definition of the law and the general fault measure, defined the transient amplitude fault measurement. The amplitude of the transient fault feeder fault measure maximum amplitude, transient fault measure normal feeder is greater than 0 and close to 0. According to detect the fault feeder. Theoretical analysis and ATP simulation results show that, this method can effectively and accurately detect single-phase resonant network grounding fault, not influenced by arc suppression coil, it proves the correctness of this method.
