Abstract: Kalman filtering is a digital signal processing tool that has been extensively used in many electric power system applications. Voltage and current phasors, power system frequency, voltage flicker, high-impedance faults, harmonic distortion, voltage dips, voltage unbalance, high-frequency transients and other power system magnitudes can be successfully computed using Kalman filters. This chapter provides a general overview of the application of Kalman filters in electric power systems, focusing on their use for the analysis of two of the most important electric power quality disturbances in modern day power systems: harmonic distortion and voltage events. Section 2 gives a short introduction to Kalman filtering and a review of the main applications of Kalman filtering in electric power systems. Section 3 describes the practical application of Kalman filtering in the estimation of magnitude and phase angle of harmonics and interharmonics in voltage and current waveforms and section 4 explains how Kalman filters can be used for detection and analysis of voltage dips, short interruptions and overvoltages in voltage supply.
