Abstract
Electric power delivery system fault location systems and methods as disclosed herein include validation of the received traveling wave fault measurements. Validation may include estimating a location of the fault using an impedance-based fault location calculation. Time windows of expected arrival times of traveling waves based on the estimated fault location and known parameters of the line may then be established. Arrival times of traveling waves may then be compared against the time windows. If the traveling waves arrive within a time window, then the traveling waves may be used to calculate the location of the fault.
