Résumé

The railway is a way that meets the country's economy, particularly in the agricultural and
industrial sectors same as in the transport of people. Direct current (DC) electrified railway systems show power quality problems such as harmonic current pollution. In this article we made a model in Matlab/Simulink of a real DC traction substation which is located in the mineral line Tebessa - Annaba (in Algeria). Our study focused on the propagation of currents harmonic in the electric network and their filtering solution. In this paper, we presents for mitigation of harmonic currents a new configuration of hybrid power filter based an combination of a shunt active power filter based on fuzzy logic controller (FLC), and Instantaneous active-reactive power theory (PQ) installed at the secondary of the transformer (medium voltage), with two passives filtering (tuned at frequencies 11 and 13) installed at transformer primary (high voltage). The simulation result with this new combination gives us the best results with minimum values of total harmonic distortion (THD).
