Dynamic railway simulation using DIgSILENT programming language

This paper presents the modeling and simulation of electrical systems for railway transportation utilizing DIgSILENT PowerFactory software embedded application called DIgSILENT Programming Language (DPL). The DPL command can be directly used to control single line grid based on tractive effort curve (TE), braking effort curve (BE) and train-speed profile. The simulations of train movements in this research have been considered as a sequence of three operating modes, namely accelerating mode, constant mode and braking mode. The simulation results show the electric power and phase voltage and distance varying by time and speed. This characteristic design leads to specific outcomes in order to improve railway transportation system and the further quality of railway system research.
