Compare prices of electricity from nuclear power and renewable energy sources
Sláma, Miloslav ; Varmuža, Jan (referee) ; Radil, Lukáš (advisor)
This work deals with the components that that creates price of electricity and the regulation of electricity prices. It explains methods of regulation, setting electricity prices. It examines the factors that affect it. It also deals with the calculation of the price of electricity from various energy sources. It studies Support RES system, the conditions for obtaining and statistical data on development aid. It adds alternative sources of energy and their future and security.

Dimensioning of Overhead Line Conductors According to ČSN EN 50341 and ČSN EN 50423
Dostál, Martin ; Novotný, Jan (referee) ; Orságová, Jaroslava (advisor)
Overhead line must be designed to be able to resist variety of influences. These influences are mechanical, which are caused by wind and rime during the normal conditions and electrical influences. Therefore all parts of overhead line have to be designed and built to withstand mechanical and electrical stress. This bachelor’s thesis is focused mainly on electrical parameters of overhead line, climatic stress and calculation of mechanical stress during limit states. There are described formulas and steps of calculation of line straining MV and HV and there are also described examples of calculation in detail.

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.

Atmospheric Phenomena
Radouš, Jakub ; Milet, Tomáš (referee) ; Kobrtek, Jozef (advisor)
This bachelor's thesis deals with a visualisation issue of several atmospheric phenomena by means of the OpenGL library. The work contains theoretical bases for rain, snowfall, lightning, fog, wind, tornado and rainbow, which are further converted to the form of algorithms. The outcome is an application with graphical user interface that is able to display seven natural phenomena set in a landscape.

Overhead Line Protection against Climatic Effects
Sýkora, Martin ; Topolánek, David (referee) ; Orságová, Jaroslava (advisor)
The outdoor overhead lines are influenced by additional load pressure of wind and frost. These can have adverse reaction on outdoor conduction of the electric power. My bachelors' report deals with separate climatic effects and possibilities of their resolution. It it also concentrates on removing the negative influences caused particularly by wind and on the possibilities of liquidation of the frost that had already originated.

Low-speed Wind Turbines for Small and Medium Size Applications
Forró, Bálint ; Paar, Martin (referee) ; Procházka, Zdeněk (advisor)
Bachelor’s thesis deals with usage of slow-running wind turbines for small and medium applications, especially with Savonius rotor. In first part I described theoretical usage of wind and analysis of wind power plants. Next part describes advantages and disadvantages of Savonius wind rotor and its practical usage. Thesis is ended with engineering design of wind rotor of this type for according performance at specific wind speed.

Timber structure of a view tower in southeast Moravia
Vrbka, Jan ; Straka, Bohumil (referee) ; Šmak, Milan (advisor)
he master’s thesis consists of a case study of an observation tower design made of glue laminated timber and steel. There are two different tower shapes of anchored or free standing tower and these towers are compared. One of the design is chosen and elaborated into final detailing. A short review of main issues bound with the observation towers is given. The review deals mainly with loading (mainly priniples wind loads are analised) and evaluating of towers (ultimate limit states, service limit states and acceleration comfort). The height of final construction is up to 60m. The design is formed by a space lattice structure made of glue laminated timber and steel members of different class. The members are fastened mainly by means of dowel joints with slotted-in-plates . There is a light steel stairway inserted into the main structure.
