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.

Utilization of renewable energy sources in Czech Republic
Kopička, Marek ; Bok, Jaromír (referee) ; Matoušek, Antonín (advisor)
This thesis deals with consideration of energy facilities structure in Czech Republic. It is depicted in it their evolution from point of: electric energy consumption, structures of energy facilities and electricity prices. Further, is here depicted a production of electric energy for the year 2009, from the point of: produce, sources, consumption and ratio of factories. Of course, the RSE (renewable sources of energy) effect and share of scope on this evolution and structure, is also mentioned here. The next part is pointed to basic description of each sources of electric energy. It is not mentioned here only factories which uses for it´s production renewable primary sources but also another types of factories. Their pros and cons are also summarized. The last part of this work is a thought of realization of fictive project, which could replace a part of steam power plants' share by producing electric energy through renewable sources. It is re-counted and suggested here a few possibilities of this realization from the point of needed installed power and approximate estimation of capital expenditure.

Renewable energy sources for one-family house
Burýšek, Jan ; Špiláček, Michal (referee) ; Fortelný, Zdeněk (advisor)
This Bachelor´s Thesis deals with the topic of Renewable Energy Resources. It is divided into two main parts. The first part is a research on renewable resources of energy which are available in the Czech Republic. The second part is focused on use of particular resources in a chosen object (house) and their subsequent efficiency evaluation.

Wind power – the past, the presence and the future
Kučera, Vítězslav ; Klimeš, Lubomír (referee) ; Charvát, Pavel (advisor)
This Bachelor’s thesis deals with the evolution of wind turbines from the past to present and also concentrates on the evolution of wind turbines in the future. In first part the begin-nings of wind energy use are given, and the first wind turbine is mentioned. Further, the parts of wind turbine and its construction are described in next part, where the current state of wind turbines in the Czech Republic and in the world is presented. New concepts of wind energy are introduced. Finally, last part performs wind turbine simulation over the span of one year.

Utilization renewable energy sources inside of EPS Czech Republik
Zmeškal, Pavel ; Procházka, Zdeněk (referee) ; Matoušek, Antonín (advisor)
The purpose of this work was the analysis of current state and further development of renewable energy in the Czech Republic. And next their effects on the electricity system of the Czech Republic. On the basis of established facts has been developed actual state of renewable energy sources. The current situation is only orientation and is still changing at this time. Another objective was to evaluate the various renewable energy sources in terms of their impact on the electricity system and recoverability in the Czech Republic. In more detail were read up the conditions for the wind power plants operation and their connection to the electricity system of Czech Republic. In fine were discuss the impact of renewable energy sources on electricity system and prerequisite for their further development in the Czech Republic.

Center winery Nemcicky
Ondrová, Klára ; Velička, Jaroslav (referee) ; Dýr, Petr (advisor) ; Kalousek, Lubor (advisor)
This bachelor thesis deals with the design of Centre of Winery for the Modré Hory area. The proposed building should respect the surrounding environment, and attract tourists in the same time, by architectural form, urban planning and design. The plot for construction is located near the village Němčičky u Hustopečí on the hilltop of Nové hory. Currently, vineyards are being restored, which almost completely cover the whole area. The object of the wine center includes a canteen for tourists, a tasting room, a cellar for storage of bottles and technical and hygienic facilities. Production component is it's own electric energy cumulator. Using a renewable wind source. Part of the proposal should be the overview tower, making the site more attractive. The object does not process grapevine, it only archives bottles and works as a showroom and stop at a wine-growing cycle path. It has a simple rectangular ground plan with a sloping roof to cover the entry part and to shield the large glazing. On the ground floor there is a café with a background, a tasting room, hygienic facilities, a brick cellar and technical rooms in the basement. The facade of the building is covered with Siberian larch wood. A viewing tower is located at the west side of the building, almost at the top of the hill. The tower has a cylindrical shape and measures almost 14.5 m. It is also clad with wood of the same type. The production of electricity is provided here by 9 vertical wind turbines located along the northern boundary of the building on the artificial wall.

Measuring station for the system of the remote energy supply
Dočekal, David ; Vaněk, Jiří (referee) ; Křivík, Petr (advisor)
This thesis is focused on the creation of measuring workplace for remote power supply system. This is the measuring of the workplace, engaged in the processing of measured data, the production of electrical energy made by a photovoltaic panel and wind turbines. In the theoretical part, the reader is familiar with the issue of renewable energy sources. The first chapter is about the energy of the wind. Here is described the emergence of the wind, the basic division of wind power, through the production of electrical energy to the measurement itself. The second chapter deals with the solar energy. This chapter describes the emergence of the solar energy, photoelectric effect, description of characteristic features and related evaluation of the photovoltaic panel. The reader learns the basic distribution photovoltaic panels here and their manufacturing. The third chapter is devoted to measurement methods and specifying the basic conditions for the evaluation of the operation of wind turbines and photovoltaic panel. In the fourth chapter describes the basic data on individual facilities, which have been selected for this thesis and the involvement of the measuring site. There is also included wind power JPT-100 photovoltaic panels A-130 anemometer TX20ETH, pyranometer SG420 and temperature sensor PT100. Measuring software is described in the fifth chapter. In the last chapter, contains the experimental measurements in the selected time interval and the actual evaluation.
