Abstract:
The railways are the most important and
modern means of transportation are used to transport a
large number of people, and also used in the industrial
field to transport heavy weight and raw materials for very
long distances. Direct current (DC) electrified railway
systems show many power quality problems such as
harmonic, reactive power, unbalanced and low power
factor. Our study concentrated on the propagation of
currents harmonics in the electric network and their
filtering solutions. 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 east of
Algeria), this line transport raw materials such as iron
and phosphate. We present in this work to mitigate
harmonic currents the passive filtering, using filters
(tuned at frequencies 11 and 13) at two different locations
before and after the transformer which freedies the DC
traction substation. The results of simulations with the
proposed solution give the best results with minimum
values of total harmonic distortion (THD) in both cases.
