In order to effectively monitor and control the interarea oscillations in a power system, it is crucial to obtain the full knowledge about the oscillation mode, such as participation level, mode distribution, frequency and damping. The paper presents an approach to estimate the participation weight of a generator in an oscillation mode based on synchronized phasor measurements and auto-spectrum analysis. The participation weight is a quantity defined in this paper to indicate the relative participation of one generator in one oscillation mode of interest. Compared to traditional participation factor computed from model-based modal analysis, the participation weight is directly defined and estimated based on the measurements of system output signals. The input-output relationship for a constant-parameter linear system when subjected to a stationary white noise disturbance is introduced to establish connection between measureable power system response quantities and participation weight. The auto-spectrum analysis is adopted to estimate participation weight with demonstrative examples, which include simulation examples as well as practical examples using measured phasor data from the CampusWAMS.
