Abstract (EN): Electric railway vehicles are supplied by substations and catenaries at increasingly high power levels being the interface between the traction motors and the overhead contact line based on power electronics converters. A large part of these are AC-DC four quadrant converters operating in parallel at relatively small switching frequencies but using the interleaving principle to reach a low harmonic distortion of the catenary current and imposing specific harmonic ranges in this current. However, the current is not a pure sinusoidal wave and its harmonics can excite unwanted resonances due to the combined effect of the catenary distributed parameters, the substation equivalent impedance and the current spectrum that can vary according to normal and abnormal operating conditions. This paper analyses this phenomenon and proposes a control strategy capable of minimizing the resonance effects. © 2019, ICST Institute for Computer Sciences, Social Informatics and Telecommunications Engineering.
