Comparison of energy mixes
Kadáková, Nina ; Milčák, Pavel (referee) ; Baláš, Marek (advisor)
This research type paper is focused on the comparison of the energy mix of Czech Republic with the energy mix of other three states, Slovak Republic, Italy and Norway. In this paper there are described energy sources which the chosen states use for production of electricity. The total installed outputs of the power plants in various years, production and consumption of electric energy and the source ratio for production of electricity are also stated, based on which the final compression is created.

Development of different types of fly ash autoclaved aerated concrete
Bednárik, Vít ; Kulísek,, Karel (referee) ; Drochytka, Rostislav (advisor)
This bachelor´s thesis deals with the current technologies of production and raw materials used in the production of fly ash autoclaved aerated concrete. The choice of suitable materials is an important prerequisite for achieving the desired properties of the finished product. Fly ash autoclaved aerated concrete has become one of the options, how to use fly ash, produced as a secondary raw material in the combustion of coal in heating power plants. This work deals with the comparison the physico - chemical properties of the fly ash in the Czech Republic and the subsequent optimization of the composition of the raw mix for the production of fly ash autoclaved aerated concrete with the maximum use of alternative raw materials.

Calculation of the network steady state on the voltage level 110 kV
Macháč, Petr ; Vaculík, Petr (referee) ; Mastný, Petr (advisor)
This thesis deals with load flow calculation of electrical network 110 kV before and after the connection to the 70MW gas supply and the 58MW steam and gas supply. This grid can be powered from two 400/110kV substations, namely Sokolnice and Otrokovice. The load flow calculation is realized for the power supply either from Otrokovice or Sokolnice. Furthermore, the calculation of the uni-phase and three phase short circuits in the substations of 110kV network is realized in this thesis. The result of the thesis is the assessment of the voltage ratio in the network, current load of the power line and short circuit resistance of the substations.

Super-heated steam cycles
Uherek, Jan ; Kracík, Petr (referee) ; Pospíšil, Jiří (advisor)
The purpose of this bachelor´s thesis is to present new, highly efficient thermal cycles used in power plants, and to compare them with classical cycles. First, the impact of these cycles on the efficiency of electricity production is examined. The following section describes power plants where the supercritical technology has been successfully installed. The last section explains the calculation of the heat transfer surface. The conclusion of this thesis attempts to outline the future of energetics from the author´s point of view.

Materials for IV. generation power plants
Hovorka, Martin ; Svoboda, Pavel (referee) ; Šnajdárek, Ladislav (advisor)
The aim of this thesis is to describe material needs of chosen Generation IV nuclear reactors – VHTR, SCWR, and MSR with the emphasis on the VHTR. It describes the main principle and a constructional arrangement of VHTR components with its material demands. SCWR and MSR reactors are described in terms of its material requirements. The middle part of this thesis is dedicated to the available material candidate analysis. Main material properties are discussed and at the end of this part the suitability of chosen materials for a flange joint in VHTR heat exchanger is assessed. The last chapter (the practical part) is focused on an experimental proposal of changeability of older materials by the new ones using the electron beam welding method.

Operation of electric vehicles, hybrid vehicles and vehicles with an internal combustion engine
Herzog, Radim ; Píštěk, Václav (referee) ; Kučera, Ondřej (advisor)
This bachelor's thesis deals with the comparison of different propulsion concepts and their consumption, efficiency, and amount of emissions produced during operation. Although electric vehicles do not produce any local emissions, it is necessary to consider that emissions are generated during the production of electricity in power plants. The main part of the thesis introduces the functional principles of individual propulsion systems. Furthermore, it describes the formation of exhaust gas emissions in combustion engines and outlines their limits. Subsequently, the amount of emissions produced by a power plant for the operation of a specific example of an electric vehicle and a hybrid vehicle is calculated. Finally, a comparison of emissions production from representative examples of each propulsion system is illustrated.

Project documentation of photovoltaic power plant category B1
Rehák, Jan ; Mastný, Petr (referee) ; Morávek, Jan (advisor)
This thesis focuses on project documentation for a photovoltaic power plant. Requirements for parallel connection of power plants with installed power from 100 kW to 1 MW to the distribution grid are studied. Next, research has been conducted on individual components and options for local and dispatch control of photovoltaic power plants. The practical part of the thesis focuses on the creation of project documentation for an embedded photovoltaic power plant located in the buildings of FEKT Brno University of Technology. The final part of the thesis includes an economic evaluation of the project.
