    High Rate Report Synchrophasor Technique during Dynamic Conditions

    Get PDF
    139–143Current industrial applications of synchrophasors in intelligent grids depend to a great extent on highly trustable measurements, mainly during dynamic conditions of a power system, like a power swing which exhibits simultaneous variations of amplitude and phase in both voltage and current. This work presents the assessment of the performance of a novel synchrophasor technique following tests of the dynamic section of the IEEE Std. C37.118.1-2011, which requests testing the simultaneous variations of amplitude and phase
