Résumé

The railways are used to transport people, but also for
the industry. In this article we present a simulation of real DC
traction power supply that intended to transport the natural
resources (iron, ore and phosphate) from its source to the
industrial areas. We made a model in Matlab/Simulink of a DC
traction substation which is located in the mineral line Tebessa -
Annaba (in Algeria). Our study focused on the propagation of
harmonic currents in the electric network and their filtering
solution. The simulations results obtained in this paper for
standard operation conditions are presented shows that a value
of total harmonic distortion (THD) current exceeds the standards
(IEEE 512-1992). In this paper, we present the most effective
solution, most used and least expensive to mitigate harmonic
currents is the passive filtering, using filters (tuned at frequencies
11 and 13) at two different locations compared to the
transformer which supplies the traction substation .In the end we
compare the results obtained by determining the THD in each
location .
