Abstract
This paper investigates the possibility of measuring fundamental and harmonic synchrophasors as well as the signal frequency using a modified Taylor Kaiman filter (TKF). In a previous paper, a modified TKF was proposed to track the complex trajectory of dynamic phasors of the fundamental frequency component based on an improved dynamic model under non-steady state conditions. In this paper, we extend the model of the modified TKF to include harmonics and to allow a better estimation of the phasor in presence of distorted signals. The new method also allows to estimate frequency and time varying harmonic components.Items in DSpace are protected by copyright, with all rights reserved, unless otherwise indicated.
