| Abstract |
Modern PWM converter-fed locomotives generate current harmonics which give rise to travelling waves in the overhead supply system. The waves are partially reflected at the feeding substations, causing parallel and series resonances at various discrete frequencies. An investigation based on the wave propagation approach demonstrates the influence of the track topography and the varying position of locomotives within the track. The distribution of harmonic currents in the overhead supply system is evaluated and discussed. It is shown that these currents are much higher in certain locations of the railway track than the harmonic current injected by a locomotive. |
