Abstract: Relay configuration equipment helps configure a protective relay for single-ended traveling wave-based protection of an electric power system. The relay configuration equipment obtains relay settings for a protective relay specifying characteristics of traveling waves attributable to fault events that are to trip the relay. The relay configuration equipment performs event simulations, including fault events and non-fault events, in the electric power system under different configurations. The relay configuration equipment then iteratively adapts settings for the relay by, in each iteration, identifying characteristics of traveling waves attributed to the simulated event, applying settings to the characteristics to determine an observed local response of the relay to the event, and generating data comparing the observed local response with an expected local response.

Abstract: A protective relaying system includes a local protective relay operatively coupled to a protected line segment at a first location, and a remote protective relay operatively coupled to the protected line segment at a second location. The remote protective relay generates a signal (PILOT RECEIVE) to indicate the detection of a fault. This signal is communicated to the local protective relay and employed therein to supervise single-pole trip operations.
