Abstract :
TEPCO has been operating the islanding protection system based on synchronized phasor measurements since 1984. In its long operational history, the system detected the system islanding without fail in 1999 and 2006. Through the two operational experiences, TEPCO has learned effectiveness of the islanding detection based on phase angle difference obtained from synchronized phasor measurements.
