Modelling and Simulation of Stray Currents in Tehran Metro System

This paper describes the Stray Current phenomenon in DC metro systems and also all the modelling and computerised simulation process of stray current and its related parameters. Finally we have run the simulation program for Tehran Metro system including Lines No. 1 and 2. At the end some sample of results and simulation outputs for the train trips between the two specified stations according to dynamic and preprogrammed movement of trains are shown here.
