Abstract in different language:	This paper describes results of the harmonic analysis of currents harmonic analysis performed for an advanced AC traction Substation. AC traction substation feeding 25 kV / 50 Hz traction catenary and provide power symmetrization by semiconductor device called electronic balancer. The analysis is concern to currents of electronic balancer part of substation and the grid currents corresponding with quality of taken energy. The harmonic currents components are evaluate with the respect to the switching frequency of IGBTs (250 Hz), modulation technique (PS-PWM) and dead time duration (10 µs). The results are evaluated on the created model of the AC traction substation with multilevel converter topology, having the nominal power of 12.5 MVA.
