Method of solution to short-circuit at traction system

Abstract

The paper represents one part of research work on the field of traction system. At the present days, the situation of railway techniques is very complicated and sophisticated both from viewpoint of railway infrastructure and from viewpoint of transport means. Moreover electromagnetic compatibility stands out in all possible technical areas it leads to research work focused on influence to surrounding parts. So, it is necessary to analyze the particular parts of the traction supply system from viewpoint of their behaviour and from viewpoint of influence to surrounding parts. The paper deals with metod of solution of short-circuit at AC 25 kV, 50 Hz tractionsupply systems by computer simulation. It was necessary to explain these effects which canoccur during failure states. The whole analysis is done with traction circuit without electric locomotives. The critical states are deduced from current and voltage knowledge and folloving analysis of these states we gain the results lead to the findings mentioned in the conclusion of this paper.This work can be used as one part of background for research work on the field of traction system.Usage of the mentioned control method opens up the others possibility for research on this field of interest.
