Title
Frequency estimation in unbalanced three-phase power systems using complex adaptive notch filters
Abstract
This paper presents a steady-state analysis of first-order complex adaptive notch filters in unbalanced three-phase power systems. By using first-order difference equation with respect to steady-state estimation error, analytical expressions of estimation bias and amplitude of oscillation error in an unbalanced condition have been derived. Closed-form expressions for bias and amplitude of oscillating error due to third harmonic have been also presented. Computer simulations show the effectiveness of the proposed analyses.
