Localization of short-circuits on single side supplied HV line
 Zíka, Jakub ; Jurák, Viktor (referee) ; Topolánek, David (advisor)
This bachelor‘s thesis deals with the localization of unilaterally fed short circuits on high voltage lines. The first part of the bachelor’s thesis deals with the research of the localization of unilaterally fed 1-Phase, 2-Phase and 3-Phase short circuits on the HV lines. Furthermore, individual types of short circuits are described here with suitable procedures for calculating the fault distance and definition of formulas for individual impedance loops. The second part of the bachelor’s thesis focuses on the implementation of these formulas for calculating the distance to the fault location. The input values of voltages and currents were simulated by a simple system model in the PSCAD program. Subsequently, a more detailed sensitivity analysis of individual types of short-circuits was carried out and possible detection of when individual calculation methods fail.
