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.
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.
