OpenPowerNet by Institut für Bahntechnik GmbH (IFB) is a micro-simulator designed as an add-on to OpenTrack to inform both design and analysis of power supply systems for electrified railways

The OpenPowerNet software package provides a synchronized co-simulation output of the traction power supply system alongside the normal outputs of OpenTrack.

The simulation of these dynamic processes enables energy consumption analysis and prognosis, design and rating verification of the electrical installations, as well as electromagnetic field studies. It allows users to see the effects of the power supply system on energy consumption and costs as well as train performance.

OpenPowerNet serves as a useful tool to solve the challenges faced in transport applications including:

  • Finding the line voltage at the pantograph and the resulting impact on train performance
  • Analysing the influence of the network structure on electrical load distribution
  • Sizing equipment such as cable, transformers and rectifiers
  • The influence of energy constraints set by energy suppliers and the ability of the network to cope with regenerated energy under different network switching conditions.

Advantages of OpenPowerNet in Your Organisation

OpenPowerNet serves as a valuable tool for all railway electrification projects as it can potentially identify risks, determine project feasibility and reduce project cost.

The benefits of using OpenPowerNet to simulate electrical network scenarios include:

  • The consideration of the combined effect of all known variables and uncertainties
  • Early detection of problems and conflicts before major decisions are implemented
  • The reduction in design errors
  • Reduce project implementation length.

The OpenPowerNet

The simulation is configured to account for variables such as the power supply system, switches and engine type. Statistical information is simultaneously recorded with the application of an OpenTrack run.

All statistical data is stored in a database which allows for organisation and comparison of electrical behaviour.
