Synchrophasors
Synchronized phasor measurements (synchrophasors) provide a real-time measurement of electrical quantities from across a power system. These measurements can be used for control, measurement, and analysis of the power system. Applications include validation of system models, measurement of stability margins, maximizing stable system loading, islanding detection, and system-wide disturbance monitoring.
- Reduce cost and complexity of wide-area measurement and event recording using SEL synchrophasor technology.
- Improve power system reliability by operating within measured stability limits.
- Check phasing and connections of current and voltage transformers.
- Use automatic or manual comparison of phasors for real-time control.
