Étude des harmoniques et techniques De Commandes du filtre actif

Abstract

The problem of harmonic pollution in the electrical network is increasingly worrying, especially with the progressive use of non-linear payloads. This work represent an effective three-phase parallel and various control and control methods used in control, in order to control the effective filter there are two important points to consider: how to control the current loaded with harmonics and control the current transmitted by active filter in the electrical grid, there are many ways to extract current loaded with harmonics, including instantaneous power. After filtration we can compare the results and prove the effectiveness of the effective filter where the coefficient current deformation is much greater than after filtering. The obtained results show by the program of simulation by MATLAB SIMILINK show a good filtering using Fuzzy logic controller then PI.
