Eastern Interconnection Situational Awareness Monitoring System (ESAMS) Demonstration Project

The demonstration of the Eastern Interconnection Situational Awareness Monitoring System (ESAMS) represents an important step toward realizing the wide-area situational awareness capabilities of synchrophasors for the Eastern Interconnection. The project demonstrated the feasibility of continuously collecting and integrating synchrophasor measurements from throughout the interconnection in real time to produce heretofore unavailable visibility of grid phenomena that affect the interconnection as a whole. More importantly, the project demonstrated that the synchrophasor systems currently operating in the Eastern Interconnection are capable of supporting real-time notification of forced oscillations, the primary example of critical grid phenomena.
