Abstract:
Traveling wave information from a single end of an electric power delivery system is used to determine a fault location on a power line of the electric power delivery system. Hypotheses of which of a plurality of received traveling waves represents a first reflection from the fault are evaluated. A determination of an arrival time of the first reflection from the fault is used to calculate a distance from the single end of the power line to the fault location.

Claim (Index 21):
A computer-implemented method, comprising:\n detecting, via a detector, an arrival time (TPK) and peak amplitude (VPK) of each of a plurality of traveling waves at a first location on the power line; and identifying TPKs corresponding to traveling waves detected after a first detected traveling wave that have the same polarity as the first detected traveling wave as hypotheses; calculating, via a processor, a set of expected traveling wave arrival times (ETWs) for each hypothesis; identifying a first number of matches (NS) of the calculated ETWs with the detected TPKs; calculating a fault reflection value, F(H), for each hypothesis; calculating a remote reflection value, R(H), for each hypothesis; determining a second number of matches (NM) of the F(H) of each hypothesis with a set of time differences (DT set) between pair-combinations of the detected TPKs received after the first detected traveling wave; determining a third number of matches (N1_M) of the R(H) with the time differences in the DT set; selecting one of the hypothesis based on at least one of NS, NM, and N1_M; and calculating a distance from the first location to the fault location based on a function of the length of the power line, the traveling wave line propagation time (TWLPT), and the selected hypothesis.
