要約(日本語): This work will utilize phasor measurement of 500kV high voltage bus of two substations provided by KEPCO (Kansai Electric Power Co., Inc.) to estimate the characteristic of dominant inter-area oscillation mode in Western Japan 60Hz Power System. The FFT filter technique is adopted to precisely extract oscillation data with designated frequency band from original phasor measurement. The center frequency of designated frequency band of interested oscillation mode is computed based on auto spectrum analysis result. Then a simplified oscillation mode can be constructed and identified based on extracted oscillation data. The estimation results based on our CampusWAMS’s phasor measurement are compared to the estimation results based on KEPCO’s phasor measurement.
