| Abstract: | The selectivity of protection can be realized by analyzing the wavelet features and utilizing the relations between the transient current traveling wave and maximum modular value of wavelet transform so as to judge the fault types before they are logically judged by microcomputer. The simulation proves the correctness of fault-type judging and the reliability of selective movement protection. |

| Keywords: | traveling wave wavelet transformation fault phase selection selectivity, microcomputer protection |
