Estimation Of Power Harmonics Using Kalman Filter
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 6
Abstract
This paper presents an optimal method for tracking the harmonics in power system voltage or current waveforms. A Kalman filter is used to estimates the harmonics of a distorted measurement signal. The Kalman filter performance depends the noise covariance matrices Q and R. In this paper tuning of these matrices are discussed. The Kalman filter’s response time is investigated for a sudden variation in the magnitude and phase of one of the harmonics present in the signal.
