The method is based on the definition of the center of inertia by operational areas based on phasor measurements on generation nodes. This visualization takes measurements of the PMUs in every single operation area and makes a unique equivalent measure which corresponds to phasor-center of inertia of each operational area. In this way, the observation of equivalent phasors by area allows an easy and clear visualization of the behavior of the power system when a contingency occurs allows the selection of adequate control measures.enPhasorUnits of measurementVisualizationElectric power systemPhasor measurement unitInertiaFrame (networking)Computer scienceMeasure (data warehouse)Power (physics)WAMS COI-Based Phasor Visualization Frame for Power System Area Separationarticle
