Power unit impedance and distance protection functions during faults in the external power grid

Power unit impedance and distance protection functions during faults in the external power grid

This paper presents the problem of the risk of an unnecessary tripping of a generation unit’s underimpedance protection functions in circumstances of generator power swings following elimination of long-lasting fault in the external power grid. The fi rst part describes typical solutions of a genera...
