Abstract:
The present disclosure relates to detection of faults in an electric power system. In one embodiment, a time-domain traveling wave directional subsystem is configured to receive a plurality of current traveling wave and a plurality of voltage traveling wave time-domain representations based on electrical conditions in the electric power delivery system. The plurality of current and voltage traveling wave time-domain representations may be compared to respective minimum thresholds. An integral may be generated based on a product of the plurality of current and voltage traveling wave time-domain representations when the current and voltage traveling wave time-domain representations exceed the minimum thresholds. A sign of the integral may reflect whether the fault is in the forward or reverse direction. A fault detector subsystem configured to declare the fault when the sign reflects that the fault is in the forward direction and the integral exceeds a security margin.

Claim (Index 11):
A method to detect a fault in an electric power delivery system, comprising:\n acquiring a plurality of voltage traveling wave time-domain representations and a plurality of current traveling wave time-domain representations based on electrical conditions in the electric power delivery system; receiving the plurality of current traveling wave time-domain representations and the plurality of voltage traveling wave time-domain representations; generating a first comparison of the plurality of current traveling wave time-domain representations to a current minimum threshold; generating a second comparison of the plurality of voltage traveling wave time-domain representations to a voltage minimum threshold; determining an integral based on a product of the plurality of current traveling wave and the plurality of voltage traveling wave time-domain representations when the first comparison indicates that the plurality of current traveling wave time-domain representations exceed the current minimum threshold and the second comparison indicates that the plurality of voltage traveling wave time-domain representations exceed the voltage minimum threshold, a sign of the integral reflecting one of a forward or a reverse direction of the fault; declaring the fault when the sign reflects that the fault is in the forward direction and the integral exceeds a security margin; and implementing a protective action based on the declaration of the fault.
