Wind power plant
Šponiarová, Petra ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
The electricity production from renewable sources is a very current topic. It also includes the electricity made by wind power plants, which the bachelor’s thesis concentrates on. An extensive research study was conducted to provide an overview of wind turbine types. Concerning wind power plants, apart from their visual impact, noise and vibration connected to their operating is an often discussed issue. The construction of a wind turbine stands for the most important role in reducing such unwanted effects. Technical experiments following specific standards and recommendations are performed to assess the impact of wind turbines-emitted noise and vibration on humans. In order to assess noise and vibration of a wind turbine a technical experiment is proposed, which uses different approaches to determine the critical components. The selection of a suitable measuring equipment and the choice of location for its subsequent use are important parts of the design. At last, the use of wind power plants is critically reviewed.

Influence of Wind Farms on Electrical Energy Quality
Bartko, Jan ; Krátký,, Milan (referee) ; Malý, Jiří (advisor)
This thesis is occupied by influences of wind farms on electrical energy quality. Object of thesis was analyse influence of these power plants in a large of number. The first part was attended to presentation of wind turbines producers and their agency on worldwide and European market. At the same time were introduced new technologies of wind power generate. The second part is occupied by influence of wind farms on electrical energy quality. In this part was created model of feed system by GLF software and wind farms were connected into it. By the help of this model was run analyze of local influences of wind power plants on electrical energy quality. In last part was assessed influence of wind power plants feed system integration on electrical energy price, build and operating costs, including the prognosis to the future.

Technical and economic proposal for wind power in the locality Břežany.
Růžička, Tomáš ; Chroboczek, Libor (referee) ; Škorpík, Jiří (advisor)
There is currently a construction project underway in the czech republic (Vesta V52) to build a large wind farm. Due to their size there is a lot of oposition to this venture. My project is a short history of using Wind Energy, the principle behind wind farms and detailed discriptions of Vesta V52 itself. You will also find a theoretical calculation of the produced electricity per year and considered cost and sustainability of the plant.

Mathematical modeling of a wind turbine
Osička, Aleš ; Mastný, Petr (referee) ; Radil, Lukáš (advisor)
The aim of this paper is to acquaint the readers with basic classification of wind turbine configuration by used electric generator, with speed and power control used in power plants and with mathematical model of wind and parts of power plant. Procedure of making model in applications Mathematica and MathModelica is described in the other part of this paper. There were made models of power plants with squirrel cage asynchronous generator, one with pitch control, the other with stall control. In the last part of the thesis comparison of model behavior of both models with the same input conditions was made.

Wind Energy Use on Flat Roofs of Buildings
Tůmová, Eliška ; Kabrhel,, Michal (referee) ; Horák, Petr (referee) ; Hirš, Jiří (advisor)
The PhD thesis is focused on determination of the method by which it is possible to specify the wind energy use potential on building flat roofs. In response to the need to reduce the production of CO2 emissions and increase energy self-sufficiency, it is necessary to use alternative energy supply systems and renewable resources as much as possible. Long-term and short-term wind parameters were measured to verify the of the resulting simulation velocity flow images. Based on the defined input parameters and the completed simulation, the resulting value of the potential is determined, namely the possible production of electricity for selected small wind power plants on the roof of the selected building during one year. In the thesis the individual steps of the method are stated and the verification of the established method is determined.

Theory of inventive problem solving
Lněnička, Luboš ; Veselka, František (referee) ; Bušov, Bohuslav (advisor)
This thesis deals with methodology for creating innovative concepts and their solving. More precisely, TIPS methodology „Theory of inventive problem solving“. This thesis is divided into four parts. In the first part, this methodology and its five basic tools are introduced. The second part provides introduction of software Goldfire Inovator including the tools which could be useful for students working on their projects. Third part demonstrates TIPS methodology on the innovation of wind power plant supported by software Goldfire Inovator. The fourth part evaluates advantages and contributions of TIPS methodology for education and practice.

Design of Roof Wind Power Plant
Augustová, Andrea ; Křenek, Ladislav (referee) ; Sládek, Josef (advisor)
Topic and aim of my bachelor thesis is research and design of rooftop power plant cover in accordance with technical, aesthetic and ecological requirements. The aim is to create a cover, which will be minimalistic and modern, won’t be a disturbing element in urban areas and its shape will increase the efficiency of the wind turbine.
