Abstract: The present disclosure relates to searching electric power system waveforms. Disclosed herein are various systems and methods for improving search performance through indexing electric power system waveforms using waveform attributes such as frequency, amplitude, angle, rate of change, and the like. According to some embodiments, multiple indexes may be used together to find information of interest. A reference signal may be utilized according to some embodiments. Normalizing a plurality of waveforms using a reference signal may facilitate the use of an index for comparing two arbitrary waveforms. This disclosure also relates to detecting and indexing islanding conditions in an electric power system. Various embodiments may utilize information relating to islanding conditions in connection with search operations.

Abstract: Combining and analyzing streamed and polled electric power delivery system information is disclosed herein. A system therefore includes a plurality of IEDs in communication with the electric power distribution system and configured to provide streaming and/or polled data via a communications network. An analysis engine in communication with the communications network receives selected streaming information and requested polled information, analyzes such streamed and polled information, and provides a display of such streaming and polled information to a user.
