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
