| Abstract: |
| Based on the results of various model component analyses, a new fault phase selection method for EHV transmission line by the energy character from model component wavelet transform is proposed. The EMTP simulation and the recorded field data show that the method is correct. The influencing factors of nonun it ultra high speed transient based protection are analyzed, the research work is reviewed and the problems to be further studied are given. |
| Key words: fault phase selection,wavelet transform,non unit transient based protection |
