OBAT - Oscillation Baselining and Analysis Tool

Focus Topic

Database of oscillation events, is able to automatically generate oscillation analysis reports

Primary Purpose

Identify system conditions when the power grid can be potentially “at risk” in terms of electromechanical oscillations

Description

The oscillation analysis block will be based on algorithms built in the OBAT (e.g., Prony and Matrix Pencil). The OBAT maintains a database of oscillation events, is able to automatically generate oscillation analysis reports, and also has advanced visualization capabilities. One of the most important features of the OBAT is the capability to perform oscillation baselining.
Several statistical methods to correlate the output of oscillation analysis algorithms (frequency, damping ratio) with system condition parameters (e.g., power flows, angle pair difference) have been developed. Statistical analysis can help to extract signatures for different oscillatory conditions. Thus, the OBAT can help to identify system conditions when the power grid can be
potentially “at risk” in terms of electromechanical oscillations.

Mathematical Description

The OBAT has two built-in oscillation analysis methods: Prony (Trudnowski, Johnson, and Hauer 1999) and Matrix Pencil(Lou,
Quintero, and Venkatasubramanian 2007). The tool can also interact with external oscillation analysis solvers. A MATLAB-based analytical module utilizing the VARPRO method has been integrated into the tool(Borden and Lesieutre 2014).
