摘　　要：研究了基于分形盒维数的输电线路故障类型识别的方法。应用ATP-EMTP对输电线路在不同故障进行仿真,计算并分析故障线路各相暂态电压的分形盒维数,提出了故障类型识别的判据方法。计算结果表明,基于分形盒维数识别方法提取输电线路的故障特征量是可行和有效的。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 .
