Course objectives:
|
The aim of the course is to provide students with knowledge of power systems and traction systems. In the field of traction systems, they will acquire advanced knowledge of the value of traction energy and power required to realize the required vehicle motion and ensure its delivery to the vehicle (separately for traction distribution systems, DC and AC traction systems, as well as energy storage systems in vehicles - i.e. electric cars etc.). Special attention is paid to current trends and requirements - especially the application of power semiconductor converters, energy saving (recuperation and reduction of losses), modern traction systems (charging station for electric vehicles), changing railway electrification system 3kV DC to 25kV / 50Hz and limiting negative effects on power grid. These aspects are also applied to other power systems (also outside the electric traction area) - i.e. for high power equipment in industry and power engineering, with power semiconductor converters (high power drives, HVDC-converters, filtration, compensation, symmetrization, variable-speed generators, etc.). Furthermore, attention is paid to the immunity of electric drives to disturbances in the network (to voltage sags, voltage unbalances, etc.).
|
Requirements on student
|
Inclusion: Participation on laboratory classes and active knowledge of topics introduced during classes. Test.
Exam: Combined - input test (at least 50% points, no question must be answered with zero points) + face-to-face exam.

Content
|
1. The traction power and energy for the required transport performance of rail and road vehicles
2. Traction power systems (variants and comparation)
3. Connection of traction substations to the power grid
4. Traction networks for city public transport
5. DC railway electrification systems (3kV, 1500V etc.)
6. AC railway electrification systems (25kV / 50Hz and 15kV / 16,7Hz etc.)
7. Negative influences of AC railway electrification systems to power grid and their elimination
8. Other aspects of AC railway electrification systemss - other negative influences (on communication and interlocking systems), cooperation of traction substations together, problems of recuperation
9. Brief introduction to electromobility (and other applications of electric traction on vehicles) and their implications for the power grid
10. Configuration of charging stations or electric vehicles and other vehicles with traction batteries
11. Special high power converters and minimization of their negative effects on the energy network (used for industrial applications and for power engineering, LCI, HVDC etc.)
12. Generators with P, Q control and variable-speed (connected to the power grid), their converters and control
13. Converters for elimination of negative effects on the power grid (for filtration, compensation, symmetrization), converters with higher immunity to fault conditions in the power grid (voltage sags, voltage-unbalance, etc.)
