Traveling-wave Fault Locator Model Development Using EMTP854

Abstract
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 b... see morelock 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.

Methods of Generating COMTRADE Files Using EMTP784

Abstract
This presentation provides two different methods of generating COMTRADE files to playback through the SEL-T400L traveling wave relays using EMTP software. The first method of generating the COMTRADE f... see moreiles uses the standard export feature in ScopeView. The second method utilizes a beta version of the COMTRADE recorder meter block to generate the .CFG files, which are later converted to .PLY files to be played back on the T400L. The advantages and disadvantages for each method are discussed along with demonstration results.
