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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
