Systems and methods to analyze waveforms from multiple devices in power systems

Abstract

Systems and methods for analyzing waveform capture data in a power system are provided. In one aspect, a method for analyzing waveform capture data in a power system includes measuring electrical signals in the power system using a plurality of intelligent electronic devices (IEDs). At least one electrical event is detected in the power system based on the measured electrical signals from the plurality of IEDs, and in response to detecting the at least one electrical event, at least two waveform captures are generated on the plurality of IEDs as a result of the at least one electrical event. The at least two waveform captures are analyzed on at least one controller coupled to the plurality of IEDs to identify at least one associated characteristic/trait from the at least two waveform captures. The at least one associated characteristic/trait is classified based on at least one of the analysis of the at least two waveform captures and the at least one associated characteristic/trait, and at least one potential relevancy of at least one of the at least one associated characteristic/trait and the classification(s) of the at least one associated characteristic/trait to the power system is determined. One or more actions may be taken based on the determined at least one potential relevancy.
