An Advanced Control Approach for a Shunt Selective Active Power Filter

N. Hamouda, K.E. Hemsas, H. Benalla, A. Boutaghane

Abstract : This paper deals with the design, analysis andsimulation of a three phase three wire shunt selective active powerfilter. It compensates harmonic currents selectively underbalanced supply network. In order to improve, the factor ofpower of the network electric. An advanced control based on amulti-variable filter is adopted. The novelty with the controlapproach developed in this paper is to use a multi-variable filter,which can extract the harmonics of references of the load current,selectively according to the axis of Concordia (?-?). Generally theharmonic in questions are of low frequencies and order 5 and 7.The objective is that the current of the network doesn't containthe harmonics desired to filtered.The shapes of waves and thevalues of the THD of the network current before and after theselective active filtering of the harmonic 5 and 7 from of theresults of numerical simulations under the Matlab/Simulinkenvironment put in evidence the efficiency of this type of activefiltering elaborated.

Keywords : harmonic, Shunt active power filter, multi-variable filter, THD
