Abstract :
An accurate, frequency-dependent rail track and traction line feeding impedance model for an overhead catenary electrified railway is described. The model is based on the track self and mutual impedances and admittances which are represented by discrete-component electrical circuit networks. Verification for accuracy is demonstrated by comparing the model track feeding impedance with reference data. The track model is used in a time-domain simulation of a DC traction network with a 12-pulse rectifier substation and a power electronic controlled traction drive to investigate the distribution of traction system current harmonics in the catenary, rails and ground
