Traction provisioning for high-speed trains

Determination of power demand for EMU traction. Calculation of traction and braking characteristics. Traction calculations. Modelling of calculated EMU operating modes.

Creation of a digital model of the EMU traction system that enables modelling of operating modes on the actual track profile under constraints imposed by infrastructure, equipment degradation, and the train timetable.

1. The mathematical model of the EMU traction system is built using mathematical data analysis and solution of the family of train motion equations.

2. Input data for the calculation programs include:

• the profile of the section where the EMU operates;
• infrastructure constraints;
• operational constraints;
• train tare mass;
• passenger count;
• possible degradation of high-voltage traction equipment;
• train timetable.

3. The result is an EMU movement diagram indicating power consumed for traction, energy consumption, and electrical equipment parameters requiring monitoring to avoid failure.

1. Use of the Visual Basic environment to model the traction system and EMU operating modes.

2. Use of mathematical data analysis algorithms, including artificial intelligence.

3. Development of the digital model uses requirements management tools: T-FLEX RM.
