Simulation of Railway Power Supply Systems – why? The electrical load flow and the energy consumption within the railway power supply network depend on the running trains and the power supply system characteristics. • There are consumers with a time-dependent and locationdependent power demand (picking up and recovering energy). • The network structure and the voltage influence the load flow. • The power supply system may influence the energy consumption. Simulation of these dynamic processes allow analysis and prognosis: • Load flow and energy consumption • Technical layout and design of the electrical installations.

Requirements The voltage situation of the railway power supply network determines the load flow and may have retroaction to the propulsion characteristics of the trains: • current and power losses increase with decreasing voltage, • under low voltage current and power limitations of the propulsion control are activated ⇒ with impact on the driving dynamics, • the network voltage influences the braking energy recovering decisively (energy absorption capability). These retroactions to be emulated in the simulation: • for a.c. networks less relevant because of stable voltage level, • for d.c. networks with high load dynamics absolutely essential

Initial Situation Energy consumption simulation for electrical railway systems requires detailed information available at the same time concerning • each train’s driving state and the required traction power, • the train’s positions within the network, • the layout and capability of the power supply system. For that reason a number of compromises were made in the past • either concerning the complexity of the railway operation simulation, • or regarding the modelling depth of the propulsion technology and the electrical network.

Summary 1. Operation Simulation (OpenTrack) • Precise railway operation simulation using a commercial simulator • Co-simulation with electrical network calculation of OpenPowerNet (New!) • Online-communication between operation and electrical network simulation via SOAP-Interface (New!) • Retroaction of electrical network calculation to train driving dynamics • automatic disturbance generation caused by the power supply (New!) 2. Load Flow and Energy Calculation (OpenPowerNet) • Complete electrical network calculation by the PSC module considering all electromagnetic coupling effects (New!) • Input of the electrical network parameters by geometrical conductor arrangement and material properties, unrestricted configurable (New!) • Switch state changes of the electrical network during simulation (New!) • Configurable modelling depth for train propulsion system in the ATM module: constant efficiency / characteristic curves / engine models + control (New!) • Comprehensive analyzing and interpreting tools (energy, load flows, currents, voltages, temporal / local) as well as data export for post-processing
