DOI: 10.1007/s00521-020-04938-z
Abstract: The similar current–voltage profile during power swing and fault quite often leads to maloperation of distance relays. As compared to symmetrical power swings, discriminating a swing scenario from a fault becomes more challenging during asymmetrical… read more here.
