Optimization of adaptive filter control parameters for shunt active power filter

Popis výsledku v původním jazyce

This article is dedicated to the study of the influence of the optimal setting of the adaptive algorithm, Least Mean Squares (LMS) to manage Shunt Active Power Filter (SAPF) capable of reducing the Total Harmonic Distortion (THD) in the power system. Authors focused on the design, implementation, and verification of a novel method for optimization of the control parameters (such as Step Size and Filter Order) of adaptive filters. The main criterion for optimal parameter selection was THD. The results of these experiments indicate that the optimum setting of the Step Size for LMS algorithm has a major impact on the speed estimate compensating current, i.e. the ability of the SAPF to respond to dynamic changes in power system. The parameter such as the Filter Order has then essential impact on the value of the resulting THD, i.e. on the Power Quality. The original contribution of the paper is to define the working area of LMS algorithm, which is a compromise between quality and speed of the estimation the compensation current. The proposed system adaptively reduces distortion, dip a flicker. Real signals for the measurements were obtained on a sophisticated threephase experimental workplace (programmable source HP 6834B, intelligent electronic device IED NI 9925).
