Výpočet zkratových proudů v trojfázových střídavých soustavách dle ČSN EN 60909

Abstract

This bachelor thesis deals with the analysis of short-circuit phenomena and then applying them in the calculation of short-circuit conditions in industry. The first section provides a theoretical analysis of short-circuit phenomena such as causes and their potential consequences. The following three chapters are based on the standards EN 60909 and describe the methodology and assumptions calculation for computing the parameters of individual elements of the electricity system and the subsequent description of the calculation of the sub-type of short circuit. In the final (practical) part is an example of the calculation of short-circuits conditions substation high voltage industrial enterprise. The calculation method is chosen by calculating the relative values.
