In fault location system based on traveling wave

the measurement accuracy of traveling wave velocity has influenced the accuracy of fault location to a certain extent.On the basis of analyzing the factors influencing the measurement accuracy of traveling wave velocity

the influence of traveling wave velocity on fault location accuracy and existing measuring methods of traveling wave velocity

using the wave of single-phase auto-reclosure to measure the traveling wave velocity is proposed for single-phase grounding fault on the transmission line

thus

the online measurement and adjustment of traveling wave velocity has been implemented.Both theoretical analysis and simulation indicate that the proposed method is easy to implement and it is effective for the improvement of fault location accuracy based on traveling wave.
