Comparison of signal processing methods for traveling-waves fault location technique in three-terminal transmission lines

This paper proposes a novel fault location algorithm based on the traveling-waves for three-terminal transmission lines. Three signal processing tools are used to show the performance of the proposed fault location methodology. The suggested algorithm is based on the application of the arrival time of first wave head at all terminals. Then, fault location indices are used to determine the fault section and the fault location. Simulation results confirm that the proposed method has high accuracy under different fault conditions for three-terminal transmission lines with arbitrary configuration.
