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.
