The Modeling of Energy Flows in Railway Networks using XML-Infrastructure Data

Abstract

This paper introduces a new Modelica package called RailwaySystem Library that provides the capabilities of simulating the energy flow in electrical railway net- works on which a fleet of railway vehicles is running. The focus of the library is set upon the interaction of the vehicle and its energy infrastructure, so that energy management aspects may be investigated from a holis- tic point of view taking the vehicle and the energy sup- ply by the electric power grid into account. However this intention substantially relies on the provision of reliable data of the infrastructure, on the railway net- work and its power grid. To this purpose the library refers to an open XML-based data format dedicated to railway IT applications. Furthermore, the library is supposed to be used together with arbitrary compo- nent libraries to model the energy subsystems such as the vehicle or the power station.
