  • According to the feature that the zero sequence of fault line significantly different from the non-zero sequence fault line in the high-order harmonic admittance conditions,combined with the characteristics of wavelet packet division and small angle to ground zero sequence fault current characteristics, a new method was proposed basing on an improved zero sequence admittance. This method makes full use of the transient fault line information and comprehensive utilization of zero sequence admittance wavelet packet reconstruct coefficient amplitude and polarity information to improve the selection and line sensitivity.Through PSCAD simulation and results showed that this method was not affected by the degree of compensation,fault location,the value of the transition resistance and the failure angle and it was able to elect fault line effectively and reliably.
