Abstract
The present disclosure provides systems and methods for generating a system-wide event report for electrical power delivery systems. A monitoring device within the power system may generate a key message upon the occurrence of a predetermined condition. A master IED within the power system may generate and/or transmit a system-wide key message to a plurality of monitoring IEDs within the power system. Digital process bus data, continuously recorded by a plurality of monitoring IEDs within the power system, may be saved locally by each monitoring IED within the power system and retrieved by a master IED within the power system. Alternatively, digital process bus data may be transmitted to a master IED and saved locally. A software and/or hardware module may be used to merge the local reports into a system-wide event report.
