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.

Detection and remediation of transients in electric power systems

Disclosed herein are a variety of systems and methods for management of an electric power generation and distribution system. According to various embodiments, a system consistent with the present disclosure may be configured to analyze a data set comprising a plurality of generator performance characteristics of a generator at a plurality of operating conditions. The performance characteristics may be used to produce a generator capability model. The generator capability model may comprise a mathematical representation approximating the generator performance characteristics at the plurality of operating conditions. The system may further produce an estimated generator capacity at a modeled condition that is distinct from the generator performance characteristics of the data set and is based upon the generator capability model and may implement a control action based on the estimated generator capacity at the modeled condition.
