Phasor Grid Dynamics Analyzer is an offline data analytics tool to perform analysis on power system disturbance, dynamics and validate accuracy of models. PGDA uses state-of-the-art algorithms like Prony, Yule Walker Spectral, HTLS and Matrix Pencil for oscillation detection and NERC standards to calculate frequency response following a unit trip disturbance.

Data Mining

EPG provides Data Mining services to mine data and provide valuable power grid performance information on oscillations, generator trips, and other events based on user defined criteria. Data Mining Service can be used to mine data, interpret and present the results and use the results in establishing alarm limits, discovering oscillations, understanding grid performance patterns such as frequency response, and identifying vulnerabilities in the transmission grid.

About EPG

Electric Power Group, LLC (EPG) has been pioneering the development and deployment of synchro-phasor technologies since 2000. Our principals have extensive experience in running and managing utility grids, investigating root causes of major blackouts (WECC 1996, EI 2003), and leveraging this deep domain knowledge to develop industry leading synchrophasor technology applications for wide area real time monitoring, visualization and situational awareness.

The EPG team has extensive hands-on experience with synchrophasor standards, networks, system architecture, deployments and performance analysis through work at EPG for leading ISO's and utilities including PJM, NYISO, ERCOT, CAISO, MISO, BPA, TVA, SCE, AEP, LADWP, SRP, Duke, Dominion, NYPA and other companies.
