This project is demonstrating full-scale, on-line and off-line software prototype tools with Entergy, WECC, and Peak RC that detect and analyze system oscillations from either ambient or disturbed system PMU measurements. In contrast to other tools, these prototypes are capable of simultaneously processing hundreds of PMU measurements-rather than only a handful. Therefore, they can estimate oscillation characteristics such as the frequency, damping ratio, energy and mode shape of both local and inter-area oscillations across the wide-area power system.
