A new generic problem formulation dedicated to electrified railway systems

In this paper, a new generic problem formulation dedicated to railway electrification systems is proposed. This formulation meets the needs for evolutivity of modern simulation tools by using meta-models for the railway network components. This approach has been applied to develop a new general-purpose electrified railway simulator. As an example, a DC electrification system has been simulated and the results compared to those of a classical simulator for validation purpose. A comparison of different resolution algorithms is also presented as a result of the possibilities offered by the new simulator.
