Power Cables Parameters
Váša, Lukáš ; Jurák, Viktor (referee) ; Orságová, Jaroslava (advisor)
In recent years, the development trend of power grids character shows increased demand for using cables of both current overhead and newly constructed lines. In order to preserve reliable operation and to predict the maintenance requirements, it is crucial to regard not only the parameters certified by manufacturers, but also externalities induced by real environment and incorporate these externalities into cable models in simulation software. The diploma thesis deals with determining of characteristic parameters of single core cables in real environment, which are affected by real grounding methods of metal shielding. The emphasis is put on analysis of current cable models in simulation software PSCAD and its evaluation using two-step experiment 1) measurement of shunt parameters in laboratory using electronic bridge model and 2) on field measurement of cable series parameters in real environment.

The parameters of MV line
Dohnal, Martin ; Orságová, Jaroslava (referee) ; Toman, Petr (advisor)
This work deals with calculation of parameters of power lines and measuring of them. First part deals with calculation of parameters of power lines. Second part deals with measurement of parameters of power lines. Third part deals with measurement of parameters of real MV line using measuring system OMICRON CPC 100 + CP CU1. Measured values are compared with calculated values.
