• There are consumers with a time-dependent and location- dependent 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.
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.
• Load flow and energy consumption• Technical layout and design of the electrical installations.
Simulation of these dynamic processes allow analysis and prognosis:
Simulation of Railway Power Supply Systems – why?

• 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).
The voltage situation of the railway power supply network determines the load flow and may have retroaction to the propulsion characteristics of the trains:
• for a.c. networks less relevant because of stable voltage level,• for d.c. networks with high load dynamics absolutely essential
These retroactions to be emulated in the simulation:
Requirements

• 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.
Energy consumption simulation for electrical railway systems requires detailed information available at the same time concerning
• either concerning the complexity of the railway operation simulation,• or regarding the modelling depth of the propulsion technology and
the electrical network.
For that reason a number of compromises were made in the past
