Study of a harmonic current compensation system using a hysteresis-controlled active filter: Design, sizing and optimization

This article presents a comprehensive study on the design, sizing, and optimization of a parallel active filter (FAT1) using a hysteresis control strategy for harmonic current compensation in an industrial environment. The study, conducted at the BRALIMA/Kinshasa industrial complex, is based on experimental measurements revealing a THDi of 43.95% with a dominance of harmonics of rank 5 (38%) and 7 (16%). The article details the analytical sizing methodology, rigorous parametric calculations, and technical compromises necessary for the industrial implementation of the system.
