| Abstract: | This paper studies the transmission line fault type identification method based on the fraetal box dimension. The fraelal box dimensions of the fault line transient voltage of each phase are calculated and analyzed in the simulations applied wilh ATP-EMTP under different faz,lts, according to which,the method of fault type identification criteria is propose.d. The simulation results show the feasibility and effetiveness of fraetal box dimension based identification method to extract tim fault characteristics of transmission hues . |
