| Abstract: | This paperstudies fault criterion, fault location and fault phase selection of UHV transmission lineaccording to the wavelet theory. The detection algorithm based on wavelets is provided andthe digital simulation result is given. The approach given in the paper has practicalvalue in the relay protection of UHV transmission line. |
| Keywords: | the wavelet transform electric transmission line fault location phase selection travelling wave |
