The objective of this work is to evaluate performance of three phasor estimation algorithms proposed in literature, under electrical system signals. Signals obtained from electrical systems response to disturbances in which the electrical system is stable or operates in a condition of transient instability, frequency or voltage. The performance during the transient state of the system is evaluated...
This paper proposes novel strategies for estimating current and voltage dynamic phasors under transient conditions. Algorithms based on: (i) Taylor-Kalman-Fourier (TkKF) filter; (ii) Taylor-Kalman (TK) filter; and (iii) Prony's method (PM), are compared respect to the conventional discrete Fourier transform (DFT). Recently, several papers argue about the DFT disadvantages in transient conditions mainly...
