Abstract

This paper proposed a new method to locate the source of forced oscillation that involves resonance with natural oscillation modes. The new method is based on comparing the oscillation mode shape of the forced oscillation with that of the natural oscillation that the forced oscillation resonating with. The location that has the largest angle difference between the forced oscillation mode and the natural oscillation mode usually indicates the location of the driving force in forced oscillations. Some examples in actual U.S. EI system verified this approach.
