Abstract: The present disclosure relates to systems and methods for detection of transients in electric power systems. In one embodiment, a system may detect and remediate a potentially destabilizing transient condition. An angle monitoring subsystem may determine an angle between a first and a second rotating machine based on a plurality of measurements. A system parameter may be determined based on the angle. A stability threshold subsystem may determine a dynamic stability threshold to detect the potentially destabilizing transient condition based on the at least one system parameter. An event detection subsystem may 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 may implement a first remedial action based on the metric of instability.
