Abstract

In this paper, the behavior of dominant electromechanical modes is investigated. Forty eight hours of Western Electricity Coordinating Council (WECC) power grid data from June 13, 2005 to June 15, 2005 is analyzed using fundamental nonparametric techniques. The analysis included taking the mean and variance of 10 minute data frames and a modification of the short-time Fourier transform (STFT) on 15 minute overlapping segments of data. These analyses provide information into how the electromechanical modes in the western power grid behave over a normal day and provide insight needed for more advanced analysis techniques.
