Abstract:
A system for accurately determining a location of a fault in an electric power delivery system using traveling waves by compensating for dispersion of the traveling waves. The dispersion may be calculated based on a preliminary fault location determination, and the arrival times of traveling wave peaks may then be corrected using the calculated dispersion. A compensation to the traveling wave propagation speed may be made using a proportionality factor to correct for traveling wave dispersion. Dispersion correction may be a function of fault type or physical power line conditions.

Claim (Index 1):
A system to determine a location of a fault in an electrical transmission line, comprising:\n a local intelligent electronic device in communication with a local portion of the electrical transmission line to obtain local electrical signals from the local portion; a remote intelligent electronic device in communication with a remote portion of the electrical transmission line to obtain remote electrical signals from the remote portion; a processor executing instructions that cause the system to:\n detect a time of arrival of a local traveling wave launched by the fault, using the local electrical signals; \n detect a time of arrival of a remote traveling wave launched by the fault, using the remote electrical signals; \n calculate a fault location using a product of a traveling wave propagation speed and a difference between the time of arrival of the local traveling wave and the time of arrival of the remote traveling wave by a traveling wave; \n calculate an error in the time of arrival of the local traveling wave as a product of a rate of dispersion and a distance from the local portion to the fault location; \n calculate an error in the time of arrival of the remote traveling wave as a product of the rate of dispersion and a distance from the remote portion to the fault location; \n correct the time of arrival of the local traveling wave and the time of arrival of the remote traveling wave using the calculated errors; \n improve the calculated fault location by multiplying a difference between the corrected times by the traveling wave propagation speed; and \n effect a protective action on the electrical transmission line using the improved fault location.
