A Simulation Tool for the Design of the Electrical Supply System of High-Speed Railway Lines

The design of the electrical supply system of high-speed railway lines involves the selection of the single phase system (one or two active conductors: 1x25kV or 2x25 kV), the design of the catenary, and the location and sizing of the substations and the autotransformers in case of a 2x25 kV system. The electrical system should be designed so the train voltages are in the admissible range and the conductor currents and transformer powers are smaller that their rated values. This paper presents a simulation tool for the design of the electrical supply system of high-speed railway lines. The tool is composed of two main modules: (1) the simulator of the railway line and (2) the electrical system simulator. The railway line simulator determines the position and power consumption of each train at each time step provided the line operation policy. The electrical system simulator solves the AC network at each time step and provides the catenary and train voltages, the conductor currents and the transformer power flows.

Keywords: High-speed railways, electrical supply system, traffic simulator, electrical simulator.
