Abstract

The paper deals with the fault states of twelve-pulse rectifier in traction substation of 3 kV DC traction system used at railways in the Czech Republic. The situation at diode breakdown of rectifier and at the same time recuperative traction vehicles in power supply section. The vehicle with recuperation can increase stress of elements in power supply system under certain conditions during fault states of rectifier. The simulation computer model was created for analysis of current waveforms in trolley line at this situation. The all simulations were done by program PSpice. The main goal is to analyze the endanger elements of power supply system and bring the recommendation for increasing of reliability of this mentioned power supply system.
