Considering the increasing number of electrified traction systems and changing technological advances in power electronics industry, it is required to successfully model electrified train systems. In this paper a DC catenary voltage model is proposed for a multi substation subway system. The proposed method is capable of simulating dynamic behavior of the train during different modes of operation. In this study, firstly, the electrical parameters of the system will be found to form distributed parameter model. In order to simplify analytic calculations, an approximate yet accurate solution method is proposed. Secondly, relations modeling voltage variation are linearized for improved computational performance. Finally, developed model is extended to multi substation case. Developed model is verified using real field data.
