Oscillatory Stability Monitoring
The PhasorPoint Oscillatory Stability application utilises the unique and sophisticated modal analysis technology (PDX) developed by Psymetrix. This technology provides continuous, real-time and full characterisation of the low-frequency modes of power system oscillation, including damping. The Psymetrix modal analysis technology has been successfully deployed operationally for over a decade.
Stability Analysis includes
- Analyses for operations (fast response)
- Analyses for planning (underlying trends)
- Identification and characterisation of dominant low frequency modes of oscillation, including mode:
- Frequency
- Amplitude (for analysed signal)
- Damping
- Phase
Events (Real-time Warning and Alarms) include:
- Mode frequency
- Mode decay time
- Mode amplitude
Visualisation features include:
- Topological display (mode amplitude, phase and alarm status)
- Mode frequency histogram
- Locus plots (mode decay time vs mode amplitude)
- Strip charts - trending
Historical data archive includes:
- Review
- Data Export
Key Benefits of the PhasorPoint Oscillatory Stability Monitoring application include:
- Improved power system security
- Increased secure power flows
- Damping controller performance enhancement
- Identification of oscillation source/control location.
- Model validation
