    WAMS COI-Based Phasor Visualization Frame for Power System Area Separation
    (Trans Tech Publications, 2012) Yubelny J. Bernal; Mario A. Ríos
    A methodology of visualization of the power system oscillation among operational areas is proposed based on PMUs measurements. 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.
