Summary:
The dynamics of inter-area low-frequency oscillations in the power system is investigated with real system data acquired by Campus PMU (Phasor Measurement Unit) / WAMS (Wide Area Measurement System) in Japan. The analysis method is implemented by the filtering of measured phasor data, which are synchronized by the GPS (Global Positioning System) signal, based on the spectral analysis to extract the major swing mode from fluctuating oscillations including many modes with various frequencies. The swing dynamics and the small-signal stability in the real power system are presented.
