Abstract
The power system is an example of a nonlinear system with many different oscillation sources and accordingly many oscillation types, including electromechanical oscillations, oscillations caused by control elements, or subsynchronous oscillations. The estimation of oscillation types in the power system gives a direct insight into the state of the system stability. The ability to estimate oscillations in real time is facilitated by installing a Wide Area Monitoring System (WAM), which enables accurate metering with accurate timestamps. The HOPS synchrophasor concentrator, in addition to its main role of collecting and processing synchrophasor measurements, has an electromechanical oscillation analysis module. This paper describes the oscillation detection tool for historical data with an aim to develop real time oscillation detection system for potentially unstable events in real-time.
