Dimensioning of Supporting Constructions for MV Overhead Lines
Křepela, Pavel ; Novotný, Jan (referee) ; Orságová, Jaroslava (advisor)
The reason of supporting constructions is to transfer all power activity and fulfill all requirements on safe operation of electrical grid. This bachelor’s thesis deals with designing of supporting constructions of the overhead line MV. The main task is to acquire knowledges about single parts of supporting constructions and to describe steps of power effects calculation according to current legislation. The outcome is a simple software application for supporting constructions design from power effect viewpoint.

Backup power supply with solar panel charging
Křepela, Pavel ; Götthans, Tomáš (referee) ; Kubíček, Michal (advisor)
This project aims to create a backup power source with solar charging for small mobile devices (through USB connector). The charger should store power in a battery that is charged either from external power source or the solar panel. In the introduction, the work deals with the theory of solar cells and batteries. Furthermore, it described the selection of suitable components and design diagram.

Planar and wired Yagi-Uda antennas
Křepela, Pavel ; Pokorný, Michal (referee) ; Mikulášek, Tomáš (advisor)
This work deals with the study of Yagi-Uda antennas, followed by analysis and design of planar antenna with wired reflector. The first part focused on the analysis of the antenna and parameters. Another part of the continuing investigation of the optimum parameters for a given antenna followed by a design in Wi-Fi 5 GHz band. The antenna is simulated in CST Microwave Studio. The final part devoted the results achieved

Dimensioning of Anchor Sections of MV Overhead Lines
Křepela, Pavel ; Jáhn, Vítězslav (referee) ; Orságová, Jaroslava (advisor)
Overhead lines are using in the vast majority for distribution of electricity in medium voltage level in the Czech republic. This Master’s Thesis deals with theoretical and practical knowledges to design and construction of these lines. Particularly, the mechanical properties of overheads lines and solving their calculation in accordance with applicable standards. The main task is to acquaint potentional designers in this sphere with this issue, which is recently ignored. An important benefit is the practical calculation of the actual overhead 22kV.
