Design of an Algorithm for Tracking Symmetrical Component Based on Adaptive Algorithm

Abstract

Symmetrical components of current and voltage are great importance in many applications in power systems such as power quality and power system protection. This paper presents the new adaptive linear combiner (ADALINE) structure for symmetrical components traction and estimation. This structure is deal with multi-output systems for parameter traction/estimation rather than the existing ADALINE, which deals only with single output system. The new topology, it is called MO-ADALINE is also presented. Finally, the paper presents a new processing unit, which can estimate symmetrical components from the measured current signals. The advantage of this proposed unit is simple to implement. Simulation results are given to validate the proposed algorithms.
