Harmonic current originating from electric locomotives can be magnified due to the impedance characteristics of power supply circuit and bring about various problems. That is, electromagnetic interference with communication lines, operational trouble in signaling, overheat and/or vibration in po wer capacitor, malfunction in protection relay and so on. Therefore, the exact assessment of the harmonic current flow must be undertaken at designing and planning stage for the electric traction systems.
For these reasons, we proposed a new approach to model and to analyze traction power feeding system focused on system response to current and voltage harmonic. Moreover, harmonic characteristics in electric train depend on its operational modes. Therefore, Measurements of harmonics are performed on the real railway power supply systems under normal operation. The spectrum and distortion analyses in measurement data are variously described in this study.
