Protective relay system having settings provided therein for all protective relay locations in a power system

摘要

A protective relay system for a power system having protective relays at specific locations in the system. Each location has specific setting information for the relay for operation of the relay at that location. Each relay in the protective relay system includes in memory all of the setting information for all of the locations in the power system. Connection of the relay to a key identifier member at a desired location, in one embodiment, provides an identification of that location to the relay. The identification may also be provided by a system computer to which the relay is connected at the desired location. The relay uses the information to obtain the correct setting information for the desired location from its memory for proper protection operation at the desired location, eliminating programming of replacement relays.
