The article presents the problem of application of a traction inverter control strategy consisting in selective elimination of harmonics (Selective Harmonic Elimination – SHE) for shaping the spectrum of traction current. The objective of this method is to reduce the conducted disturbances generated by a traction vehicle to the level below admissible values. The selection of the order of harmonics being eliminated from a voltage spectrum influences the values of the remaining voltage harmonics, hence the harmonics spectrum of current consumed from a DC network. The presented study aimed at developing the SHE method to the extent enabling its implementation to the real drive system. The article describes the results compared with limits existing in PKP (Polskie Koleje Państwowe – eng. Polish State Railways), however the presented methodology can be successfully employed for any applicable limits in DC electric traction systems.
