Abstract

Various embodiments described in this disclosure pertain to methods and systems for detecting and evaluating oscillations in an electrical power grid. The oscillations can include one or more oscillatory conditions, which can occur in one or more of five predefined frequency bands. Each of the five predefined frequency bands is categorized at least in part, by oscillations that are originated by uniquely different sources. In one embodiment, an oscillation detector can be used to detect the oscillatory condition and determine a magnitude characteristic, a phase characteristic, and/or a damping characteristic of at least one oscillation frequency that contributes to the oscillatory condition.
