Abstract
The energy consumption of electrical railways is mainly influenced by the
driving states and the propulsion efficiency characteristics of the trains as well as
by the behaviour of the traction power supply system. For this reason the idea
was to create a plug-in simulation module for railway power supply networks
using the advantages of an existing commercial railway operation simulator. The
newly developed energy simulation module called OpenPowerNet works
together with the Swiss OpenTrack railway operation simulator as a so called
\“co-simulation”. OpenPowerNet is able to simulate all common AC- and DCrailway
power supply systems taking into account the entire electrical network
structure. It can be used as an energy prognosis and analysis tool as well as for
the planning and optimisation of power supply installations. The accuracy of the
simulation was verified by a large number of real time measurements.
Keywords: simulation tools, planning, operations quality, energy management,
power supply systems.
1 Introduction
For prognosis and analysis of railway energy consumption the use of simulation
tools is state of the art today. For that purpose a considerable number of software
tools with different preciseness is available. But the modern software technology
offers new possibilities to improve the simulation.
The electrical load flow within railway power supply networks and the train
energy consumption depend both on the running trains and the power supply
system characteristics. In contrast to public energy distribution systems there are
moving energy consumers with a time-dependent power demand picking up and
