Simulation of the traffic of electrical traction vehicles as an auxiliary equipment for designing or diagnostics of existing railway lines

The driving force of an electric traction vehicle depends on the vehicle's power and the amount of electricity consumed. However, a particularly important parameter in the 3 kV DC traction is the voltage on its pantograph, which closely connects the traction vehicle and the power system. In turn, the voltage level depends on the power supply parameters of the railway line and the quantity as well as quality and location of other electric traction vehicles in the considered area. The article presents a digital model of movement for electric traction vehicles in the given power supply area.
