Purpose – dc electrified traction systems are a potential source of stray currents. The purpose of this paper is to evaluate the harmful effects (electrolytic corrosion) that an electrified railway has on nearby earth return circuits (e.g. pipelines). Design/methodology/approach – The electric circuit approach, based on the earth return circuit theory, to model stray currents interference on extended structures is presented. An exact method of calculation is applicable to any dc railway system in which tracks can be represented by a single earth-return circuit (equivalent rail) with current energization. In the approximate method, the equivalent rail with current energization is modeled as a large multinode electrical equivalent circuit with lumped parameters. The circuit is a chain of basic circuits, which are equivalents of homogenous sections of the rail. The electrode kinetics (polarization phenomenon) is taken into account in the model developed. Findings – Formulas in partially closed forms are deri...

Electric traction systems are a potential source of stray currents. The important problem, technically is to evaluate the harmful effects (electrolytic corrosion) that an electrified railway has on nearby earth-return circuits (e.g. pipelines). This phenomenon is stochastic and may aggravate electrochemical corrosion in different pipeline regions depending on the position of the vehicle, the load current, soil parameters, etc. The electric circuit approach, based on the complete field method of solution of the transmission-line problem (the earth-return circuit theory), to model stray currents interference on extended structures is applied. The electrode kinetics non-linear (polarization phenomenon) is taken into account in the model developed. Random algorithm allows to explore the phenomenon of polarization for different cases and complex route of underground pipelines which allows for generalization of the conclusions regarding the risk of corrosion in the studied systems.
