Phase Angle Monitoring

This paper addresses how synchrophasor technology can be used for phase angle monitoring and describes the various synchrophasor-based applications being used by electric utilities and grid operators presently. Uses for phase angle monitoring include:

• Wide-area situational awareness and visualization
• Line reclosing
• Verifying operation of synch check relays
• Setting alarms and alerts
• Improving state estimator solutions.

This paper may be updated in the future to include additional applications, update features of existing applications, functionality and methodologies as new information is received.
