Fault detection on the transmission lines using the time domain reflectometry method basing on the analysis of reflected waveform

摘要

The faults can happen to transmission lines at any time, any places and caused by different reasons. An accurate and fast solution to detect, locate and isolate the faults will improve the quality of the power systems' performance. The time domain reflectometry (TDR) method basing on the analysis of reflected waveforms on the transmission lines to detect the faults and estimate the fault resistance and the load characteristics has many advantages, especially when combining with the wavelet decomposition algorithm. This paper presents the numerical results using Matlab-Simulink models to show the high quality of the proposed method.
