Improving the power quality using the Active Power Filter. Experimental results

Abstract

This paper presents a simulation study and an experimental implementation of a three-phase parallel Active Power Filter, to improve the power quality by attenuating harmonics in the current and improving the power factor. The control strategy of the Active Power Filter for this work is Indirect Control. In the first stage, the Active Power Filter is evaluated by simulation in Matlab/Simulink and then experimentally validated on a laboratory stand. On the software side, LabView was used with the NI cRIO 9039 chassis and the NI 9223 and NI 9402 modules. Both the simulation results and the experimental results demonstrated the improvement of the power quality by using the Active Power Filter.
