What is OpenPowerNet?

OpenPowerNet is a traction power supply and train performance simulation software developed by Institut für Bahntechnik GmbH, BO Dresden, and is certified according EN 50641:2020. OpenPowerNet does the traction Power Supply Calculation in module PSC as well as the Advanced Train Model simulation in module ATM. The operational simulation is done by OpenTrack in co-simulation with the electrical simulation. OpenPowerNet has a retroactive effect to OpenTrack.

OpenPowerNet is developed by Institut für Bahntechnik GmbH, BO Dresden as an in-house tool. Since July 2009 a commercial and since March 2010 a academic license is available. In case you are in need of a traction power supply simulation respective simulation tool please contact us. We provide OpenPowerNet licenses as well as the service to simulate and analyse traction power supply networks.

OpenPowerNet main functionality:

• Load flow analysis for 1AC, 2AC and DC networks
• Calculation of tractive effort for OpenTrack
• Calculation of braking effort and recovered energy for network simulation and analysis
• Advanced Train Model with tractive and braking current limitation, power factor versus voltage, recovery braking, eddy current braking, ...
• Engine model with multiple propulsion systems is available
• Automatic calculation of the magnetic coupling between conductors
• Modelling of power supplies such as rectifier/inverter, transformer, converter (SFC)
• Modelling of station energy storage for stabilisation of line voltage and energy saving
• Modelling of engine energy storage chargeable from OCS and allowing running on OCS free track sections
• Modelling of booster transformer
• Modelling of voltage limiting device
• Calculation of short circuit currents along the line
• Calculation of line voltages for constant current engines to analyse the electrical network
• Energy balance
• Consideration of coasting behaviour of the courses
• Load analysis of equipment
• Touch voltage calculation
• Electromagnetic field calculation and visualisation
• Visualisation of results using the automated analysis of the Analysis Tool
• Automated analysis generates the tables and diagrams in any language by user configuration using UTF-8 characters.

What's new in Version 1.10.0?

• This release comes with the new network model element library. This library contains conductors and connectors as well as typical substation designs and devices.
• For simulations with constant headway the analysis allows now to generate substation results for a longer period then the actual simulation. This feature is called time window repetition.
• The overload detection has improved significantly.
• Furthermore, a number of bug fixes is included in this release.
• More detailed information is available at the Release Notes.
