WELLS - Early Detection of Islanding and Real Time Modal Damping Calculations Using Time Synchronized Data from Highly Reliable PMU Systems

OSIsoft, LLC. , USANumerous recent events have illustrated the importance and usability of synchrophasor data. Islanding events and system separations have occurred on the North American power grid, where synchrophasors may have been the only system to detect the event. Because of the critical nature of this information, it is not enough to simply transmit data and hope the data arrive at the desired location and are processed correctly. This paper outlines a method of configuring redundant phasor measurement units (PMUs) using commercial off-the-shelf hardware and software. Advanced data analysis is also introduced to increase the usability of the information to operators in order to enhance situational awareness.
