Phase Angle Differences What They Mean and How to Use Them For Operations
This webinar focused on providing an in-depth understanding of Phase Angle Differences and how operators can use the measurements to diagnose and take appropriate action for reliable grid operations. Increase in phase angle difference between source and sink in a grid is an indicator of stress that is often not evident by monitoring power flows. Monitoring phase angle difference between Ohio and New York in 2003 and between Oregon and California in 1996 would have alerted operators to emerging problems well before the cascading blackout. |
