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 systems.
OpenPowerNet main functionality:
- Load flow analysis for 1AC, 2AC and DC networks
-
Modelling of
- Power supplies such as rectifier/inverter, transformer, converter (SFC)
- Controlled rectifier and inverter
- Wayside energy storage for stabilisation of line voltage or energy saving
- Onboard energy storage chargeable from OCS and allowing running on OCS free track sections
- Booster transformer
- Voltage limiting device
- Engines with tractive and braking current limitation, power factor versus voltage, recovery braking, eddy current braking, onboard energy storage, ...
- Engine with multiple propulsion systems, e.g. AC and DC
- Consideration of coasting behaviour of the courses
- Calculation of

- Convenient execution of multiple simulations and analysis managed by the Automation Config.
What's
in version 1.15.0 ?
- Main new feature is the so-called DC Converter (DCC) model. It allows to define a voltage over current curve, in this way its possible to model a controlled rectifier and inverter.
- Another new feature is a new type of lines diagram to generate a curve showing the maximum time the voltage was above/below a threshold voltage.
- ∆t_below_U_threshold = f(s): Visualises the maximum time the voltage was below the threshold voltage as it is defined in Preset File. By default, the threshold voltage is defined according EN50163.
- ∆t_above_U_threshold = f(s): Visualises the maximum time the voltage was above the threshold voltage as it is defined in Preset File. By default, the threshold voltage is defined according EN50163.
- Last but not least, new vehicle curves showing consumed and recovered energy separately in two curves. The combined curve was already available.
- More detailed information is available at the Release Notes.
