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.

Business Project in the Area of Renewable Resources of Energy
Kerndl, Michal ; Kallabová,, Eva (referee) ; Heralecký, Tomáš (advisor)
The aim of my thesis, which is called „Business project in the area of renewable energy resources“, is to analyze business opportunities in the area of renewable energy resources, which have been highly actual and discussed recently, whether in term of benefit for environment or in connection with international problem of shortness in energy resources. Result of this thesis is, on the basis of the analysis, to define recommendations in the form of optimal proposal for realization. The thesis is engaged in description of current state in the area of the renewable energy resources, their utilization in practice and consequential proposals for realization including project financial plan. The thesis is also engaged in possibilities of state budget and EU grants use.

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.

Nonconventional Utilisation of Wind Energy
Zajíc, Josef ; Turek, Vojtěch (referee) ; Jícha, Jaroslav (advisor)
The thesis considers utilization of the wind energy as source of energy for the production of hydrogen. In the first part, there is described the types of wind engine specialized especially on screw wind engines and their construction. After that follows the description of dilemmas usage of electric energy addicted in time and with it connected problems with accumulation elektricity by the help of various methods. The final part of the thesis is than addicted to statistic evaluation of wind conditions, description and suggestion of the equipment hydrogen management.
