Abstract
Fault location using traveling waves in an electric power delivery system according to the embodiments herein uses line parameters that are adjusted using traveling wave reflections from known discontinuities in the electric power delivery system. The arrival times of a traveling wave and a reflection of the traveling wave from a known discontinuity may be used to adjust parameters of the electric power delivery system such as, for example, line length. The adjusted parameter can then be used to more accurately calculate the location of the fault using the traveling waves.
