What is OpenPowerNet?

OpenPowerNet is a traction power supply and train performance simulation software developed by Institut für Bahntechnik GmbH, BO Dresden. 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.
