Uninterruptible power supply
Podal, Pavel ; Rampl, Ivan (referee) ; Chmelař, Milan (advisor)
The objective of this work is to inform readers on classification of Uninterruptible Power Supply (UPS). depending on the equipment for which is to be used. Voltage quality has a decisive influence on the operation of equipment. There are various common power problems that UPS units are used to eliminate. Furthermore, I described backup power sources of energy used for UPS, in partikular secondary battery. This text is about UPS technology used for critical applications, witch must not fail due to a power outage or other power anomalies too.

Hydro power station design
Novák, Pavel ; Grepl, Robert (referee) ; Ondrůšek, Čestmír (advisor)
This thesis deals with designing a small hydraulic power plant, where a swirl turbine is conected to a unique synchronous working, which will offer a reliable and easy installation of the hydraulic power plant. As a result a wider potential of energy could be produced from renewable resources. The use of a narrow rottor as a holder of the permanent magnets is the biggest difficulties of this design.

Business Plan
Bureš, Ondřej ; Polák, Michal (referee) ; Pernica, Martin (advisor)
This diploma thesis deals with harvesting electrical power from renewable resources - natural raw materials, specifically from biomass, by means of energy producing equipment - biogas station. Theoretical part is focused on possibilities of energy production from renewable resources, analysis of administrative measures connected both with power engineering legislature and limited company establishing. It deals with procedures necessary for implementation of the plan and funding possibilities - grants and long term bank loans. Following analytical part is aimed to particular identification of surroundings, chances and risks connected with proposed design. Prospectus with the objective of establishing limited company BS Cerekvice nad Loučnou, s.r.o. is described in the project; this company will be focused on construction and operation of biogas station, producing electric power and heat.

History and development of czech power plant
PAVLOVSKÁ, Amalie
The main aim of the work was to understand the complex and demanding path in the development of energy and power engineering in the Czech lands from the end of the 19th century to the present. The introduction generally outlines the intention to briefly exclude the key moments that affected our energy. The next sections first describe the historical individual periods in which the power plants were built on the basis of certain conditions. Then I deal in detail with the most frequently used types of power plants in the Czech Republic with more emphasis on one of the modern technologies of the Temelín Nuclear Power Plant. The last larger chapter is a reflection on the possible development of energy in the future.

Modern Application for Household Heating
Šoupal, Filip ; Brázdil, Marian (referee) ; Lisý, Martin (advisor)
This bachelor thesis is focused on the research of basic sources, methods, and possibilities of heating modern family houses. The thesis is divided into three parts, the first one is focused on the advantages and disadvantages of individual heating sources in the use of renewable and non-renewable energy sources. The next section thoroughly describes and compares the methods of heating considering current emission standards. At the end, there is a technical and economic comparison of the variant of the current gas boiler with the variant of the automatic coal boiler and the modern heat pump. The comparison in interpreted on a model house through performed calculations. For better accuracy, the thesis is enhanced with pictures and tables.

Budování a provoz bioplynových stanic a jeho dopady na lokální rozvoj z pohledu obyvatel obce – případová studie Velké Albrechtice
Červenková, Ivana
Diploma thesis Building and Operation of Biogas Stations and Theirs Impacts on Local Development from the Perspective of the Municipality´s Residents – A case study of Velké Albrechtice deals with the impact of the operation of biogas stations in the municipality of Velké Albrechtice on local development from a perspective of local residents. As a part of this work, a questionnaire survey and analysis of biogas stations in the municipality were carried out. The theoretical part is based on an identification of energy sources and their division. More attention is paid to renewable energy sources, respectively to secondary energy sources. It also focuses on establishing of the concept of biogas plants, theirs functioning, advantages and disadvantages. In addition, it describes problems and conflicts with the establishment of biogas plants. The practical part of the thesis presents the case locality - the municipality of Velké Albrechtice and specific biogas stations. Additionally, it evaluates opinions and attitudes of the local population towards these stations both before going to production and at present. It also includes an analysis of the results of the questionnaire survey and discussion about it. The output of the thesis is a comparison of the situation in the initial period of conflicts and current problems with the functioning of biogas stations. Moreover, it inquires whether there have been any changes both from the perspective of residents and in the operation of the stations. Reasons of these changes are evaluated at the discussion of the thesis. Next, the most significant positive and negative effects of the construction and operation of the biogas plant on the life of the community and its development are identified. Last but not least, the thesis conclusion formulates recommendations that can improve the future development of biogas plants in the Czech Republic and can prevent conflicts between biogas plant operators and the local population in other locations.

Energy assessment of the building
Bidmonová, Renata ; Velísková, Eva (referee) ; Hirš, Jiří (advisor)
The bachelor thesis deals with the energetic evaluation of the building in Brno. It is divided into three parts. Part A focuses on basic definitions and division problematics under applicable laws, decrees, and technical standards. Part B provides a more detailed description of the individual relationships and calculation procedures used to process the parts of the building's energy performance certificate. Furthermore, proposals for measures to improve the energy performance of a building, economic and environmental assessment. Part C contains a description of the object, its construction solution and the specifications of the BS (Institute of Building Services) systems. Furthermore, the calculation of energy needs for individual BS (Institute of Building Services) systems. Designing austerity measures for a given object. The main part of the bachelor thesis is experimental measurement and its evaluation.
