Abstract:

This paper presents the canonical correlation analysis (CCA) and Yule Walker (YW) analysis of PMU (Phasor Measurement Unit) measurements recorded in the framework of the MedFasee BT Argentina Project that observes the dynamics of the Sistema Argentino de Interconexión (SADI). The CCA and YW method are used to determine the low frequency oscillatory modes with low damping present in the voltage and frequency signals. These modes are characterized by their frequency, damping and pseudo-energy. The CCA and YW method is applied to ambient type data measurements of PMU´s. This study, besides allowing the detection of low damping modes, allowed to determinate different parameters of the methods as signal to be analyzed, which is a requirement for the preprocessing, as well as the definition of the analysis window, sampling period and system order.
