Abstract :
The Frequency Monitoring Network (FNET) takes GPS-synchronized wide-area measurements in a low-cost, easily deployable manner at the 120V distribution level. It has been monitoring the North American power grid since 2004. Various advanced situational awareness tools have been added using FNET data. Examples include disturbance alert, event location triangulation, oscillation detection, and a number of real-time visualization tools. Power system disturbances characteristics in North American power grid is examined in this paper based on FNET captured events from 2009 to 2010. Further, this paper investigates system dynamics during several major disturbances in Eastern Interconnection and Western Interconnection captured by FNET in 2010.
