1. A system configured to detect and remediate a potentially destabilizing transient condition in an electric power system, comprising:

  • an angle monitoring subsystem configured to determine an angle between a first rotating machine and a second rotating machine based on a plurality of measurements and to determine at least one system parameter based on the angle;

    a stability threshold subsystem configured to determine a dynamic stability threshold to detect the potentially destabilizing transient condition based on the at least one system parameter;

    an event detection subsystem configured to compare at least one metric of instability to the dynamic stability threshold and to detect a first potentially destabilizing transient condition based on the comparison of the at least one metric of instability to the dynamic stability threshold;

    a remedial action subsystem configured to determine a first remedial action based on the metric of instability.
