Abstract

This dissertation describes effects of one-phase railway engines on voltage asymmetry within a power distribution system. Chapter „Czech railways electric traction“ deals with traction distribution systems, its power supply and various kind of the engines themselves. Follows a theory describing asymmetry using the method of symmetric components, asymmetry analysis and some technical procedures for asymmetry elimination. The very next chapter pays attention to both traction transformer station arrangement and measurement done on it resulting in a final measure evaluation provided in the very last chapter.
