Combined use of solar energy
Zeman, Miroslav ; Novotný, Jan (referee) ; Matoušek, Antonín (advisor)
This thesis focuses on the combined use of solar energy. The solar conditions in the Czech Republic are listed in the first part. Further, there is the classification of solar collectors focusing on certain types and detailed description of the solar system scheme. The second part discusses the principle of photovoltaic and its historical development considering panels from the first mentions up to the present. The third part is aimed at the selection of the appropriate object and determination of its power consumption. The following chapter discusses the appropriate connection of the photovoltaic systems, the first connection containing only one inverter, the second containing two low-power invertors. The chapter also contains the connection of the solar system and a description of the individual components considering all schemes. The last chapter includes the technical-economical assessment of the whole project and the calculation of the payback period in case of photovoltaic systems.

Use of solar energy in CR
Krištofík, František ; Novotný, Jan (referee) ; Matoušek, Antonín (advisor)
The work deals with the use of solar energy as one of renewable energy sources, hence the possible successors to fossil fuels in the energy future, present, looking at solar energy and its energy position in the world today. It addresses the possible advantages and disadvantages of using solar energy. It brings thoughts of the ecological and economics and suggest possible compromises. Next part is focused on the use of the climatic conditions of the Czech Republic and compares the efficiency of solar collectors and photovoltaic panels.

Ecological problems energetics CR
Mahdal, Vlastimil ; Ptáček, Michal (referee) ; Matoušek, Antonín (advisor)
This project presents the current state of power engineering, power resources in the Czech Republic and the impact of power resources on the environment. The first chapter describes the nature of the power engineering of the Czech Republic and the structure of primary energy sources, the next chapter present the current state of electricity, there is also described the structure of instaled capacity, consumption and production of electrical energy. The following section describes the impact of the power stations on the environment and their current status in the Czech Republic. The practical part provides information of calculating emissions using emission factors for power stations of company ČEZ, a.s. and about the storage of nuclear waste. The last chapter is dedicated to reducing carbon dioxide emissions in the European Union and describes measures in the Czech Republic for reducing these emissions.

Project of Small Water Power Station
Hlavica, Tomáš ; Novotný, Jan (referee) ; Matoušek, Antonín (advisor)
Hydroelectric power plants in the Czech Republic are the most important component of electricity production from renewable sources. A hydroelectric power plant in our country produces 3.9% of the total energy, which is almost half of the 8.2% of all renewable sources. Regarding the large hydroelectric power plants and those already in the Czech Republic is very likely to accrue more, because in this sphere we need to focus on smaller hydroelectric power plants, up to 10MW included. The task of this project is to design just such a small hydropower plants (SHP), which could be an interesting investment for people nearby of larger rivers. In the first part of my project is to choose a suitable area for construction of SHP. In the second part is ma task identify and propose solutions water and hydropower

A study of small water power resource
Demovič, Petr ; Pěcha, Jiří (referee) ; Matoušek, Antonín (advisor)
This Bachelor thesis deals with a concept of a small hydro power plant. The first part is focused on hydro power potential of the Czech Republic, the general theory of small hydropower plants and their division. The following part discusses about the selection of suitable localities for construction of small hydro power plant and the decision of choosing the best of them. The selected locality is described and evaluated. Subsequently, the thesis deals with the theory of water management and hydro power solution of small hydro power plant. As the next step was to design the most suitable turbine. Then the thesis characterizes the concept of electric part of the small hydro power plant and its connection to the distribution network. This part is focused on the design of the most suitable generator, compensation of reaktive powers, a concept of cabel for pulling of power of power plant a protections. The last part is about economic evaluation of the entire investment and environmental evaluation.

Analysis of Using Cable Sections in the Route of 400 kV Overhead Line
Belatka, Martin ; Rusek, Stanislav (referee) ; Modlitba, Petr (referee) ; Matoušek, Antonín (advisor)
The thesis deals with the use of cable sections in the overhead transmission route of the 400 kV transmission system in the Czech Republic, with the design of the arrangement of the cable route and with the solution of the crossover of the cable line with other networks of the technical infrastructure or natural obstacles. The thesis shows what the construction of a 400 kV cable line in the overhead transmission route - which has not been implemented in the Czech Republic as of yet - entails in practice. The first, general part deals with the electrical properties of both the cable lines and the combined overhead transmission lines with intermediate cable sections, and this sets out limitations on the maximum possible length of the cable sections. The following chapters provide an analysis of the magnetic field of the cable line, its impact on the surrounding environment and the possibilities of its shielding. On the basis of this knowledge optimization of the designed cable route arrangement is carried out in order to make the route comply with hygiene limits. The next part uses selected locations on a real route of overhead 400 kV transmission line to show what the construction of cable sections inserted into the route of overhead 400 kV line would involve. The design includes a professional estimate of the time and financial demands of the construction.

Design of micro hydro power plant
Pušec, Daniel ; Radil, Lukáš (referee) ; Matoušek, Antonín (advisor)
Hydropower, in large or small scale, is by far the most important source of renewable energy worldwide. It provides about 19% of world’s elektricity. Small hydropower plants are one of the most cost-effective and enviroment benign technology. Currently installed capacity in Europe is about 180GW (exluding pumped storage plants), but it is covered by nearly 90% by large scale hydrpower plants. In Czech republic, about 3% of all produced elektricity is covered by hydrpower plants, exactly about 2,400 GWh anually. Nowadays, it is already exploited nearly 2/3 of all technically available hydro potential for small, mini and microhydro power plants in Czech republic. Unexploited is about 30%, it correspondents to 600 GWh annually. This thesis follows-up with design of micro hydropower plant, which includes choosing of suitable place for the plant and design its hydroenergetic solution.
