Abstract
This paper is devoted to experimental and calculating research of induced voltage on disconnected transmission lines caused by the influence of AC railway overhead contact system. Theoretical researches have been carried out by means of mathematical modeling in the ATP-EMTP programme. The programme allows simulate the power lines and traction networks using their physical parameters taking into account changes of the mutual arrangement of geometry. The values of currents and voltage of a traction network have been used as input data for the researches. Experimental research of induced voltages and currents in the traction network has been performed on the overhead transmission line and single-track railway section located near. For the design study of the induced voltage the models of convergence of the objects in two versions have been constructed: when there are one and two rolling trains on the influencing railway section. In most cases comparing results of calculating and experimental researches of the induced voltage on the line examined has shown little relative accuracy of the calculated values (4–7 %). The research results allow us recommend the programme complex ATP-EMTP use to assess of induced voltage level on the disconnected overhead power lines having convergence sections with electrified railways with the possibility to use maximum dynamic current of inducted contact network.
