Traveling-wave Fault Locator Model Development Using EMTP

This presentation briefly discusses the development of a computer model of a traveling-wave based fault locator using EMTP, as well as simulation results using the developed model. Specifically, the block discussed in this presentation is based on the double-ended method of fault location. Traveling wave extraction from raw waveforms and the time-of-arrival estimation using appropriate signal processing techniques are also briefly discussed. Simulation results using the fault locator model in a transmission system model are shown, and comparison of results with the fault locator of an actual traveling-wave relay are presented as well.
