Estimation and Detection of Oscillations in Electrical Power System

This article describes the implementation of modern signal analysis techniques for modern electrical power systems. The methodology involves the Hilbert-Huang transform supported by Empirical Mode Decomposition (EMD) and the variation of Robust Empirical Mode Decomposition to decompose a signal into its intrinsic mode function (IMF). A tool based on the arrest of oscillations and different characteristic frequency modes of electrical systems is used.
