Recently, there has been an increase in the deployment of Phasor Measurement Units (PMUs)which has enabled real time wide area monitoring of power system. PMUs can synchronously measure operating parameters across the grid at typically 30 samples per second, compared to 1 sample per 2-5 seconds of a conventional SCADA system. Such an explosion of time-stamped data in power systems has provided an opportunity to make electrical grids more reliable. Additionally, it has also brought a challenge to extract information from continuous high speed data streams.
