摘要：

This paper discusses the rolling blackouts implemented by the Korea Electric Power Corporation (KEPCO) on September 15, 2011, and a low-frequency oscillation that occurred at that time. On the day of the rolling blackout, spectral analysis and mode analysis were performed using the data obtained from a synchrophasor installed in the KEPCO system. Low-frequency oscillation modes near 0.68 Hz and 0.5 Hz occurring respectively before and during the process of forced load shedding were estimated. These wide-area oscillation modes may cause total blackouts, and may be good indicators of reliable system operation in the event of similar wide-area rolling blackouts in the future.
