Support of the energy sources construction for households
Stručovský, Aleš ; Radil, Lukáš (referee) ; Bartošík, Tomáš (advisor)
This bachelor thesis deals with the comparison of energy sources used for residential construction. It focuses on photovoltaic power plants, wind power plants, hydropower plants and cogeneration units. Budget cost of energy source is limited to the amount of 550 000 CZK. Every source of energy is defined by its feature, operating principle, advantages and disadvantages. Options of selling the produced energy and its price are specified. Furthermore, the particular building licence applications (construction administration approval, generation of power questionnaire, application for connection to the distribution network, application for the contract of energy production support) including all the necessary enclosures have been analysed. Essential aspect for buying the energy source is its power and it is chosen according to the type of source. Energy source of hydropower systems is flow and gradient, in wind power systems it is wind speed, in photovoltaic power systems it is sufficient intensity of sunshine and in cogeneration units its dependance on annual heat consumption. Specific energy source available on our market is chosen for every group and the calculations of annual electricity production, period of repayment and profitability in 20-year running period are performed.

Low potential heat for electrical power generation
Dobiáš, Jiří ; Radil, Lukáš (referee) ; Bartošík, Tomáš (advisor)
This bachelor’s thesis deals with low potential heat sources for electrical power generation. It mentions primarily low potential heat sources, their distribution by origin and where you can find such resources. Another part deals with the technology that uses low potential heat to heat production of higher temperature level and power generation. These are discussed here with a heat pump, regenerative heating, Stirling engine, solar collectors, Peltier cells, etc. In addition is to their use in practice. The last chapter deals with the replacement of the heater in the regeneration heating coil from the solar collectors. It is thus the use of renewable energy sources. Carry out technical and economic calculations for the real utility of such a plan.

Usage of gasification units for electrical power generation
Kučera, Michal ; Mastný, Petr (referee) ; Bartošík, Tomáš (advisor)
The Bachelor's thesis deals with gasification and possibilities of its utilization for electric power generation. It begins with brief historical introduction of gasification and comparison of gasification with combustion. The thesis is particularly focused on coal gasification. Hence the actual role of coal in power engineering is described and some basic coal properties are discussed. In the next part the coal gasification technologies are mentioned. The thesis also deals with cooling a cleaning of the gas. Next to the utilizing of gained gas for power generation, there are other application where gasification can be used. But more attention is paid to the possibility of using gasification for power generation in power plants working with integrated gasification (so-called IGCC) and in consequence, the actual world situation is reviewed. At the end of the Bachelor´s thesis, the power

Comparison and classification of ecological impacts of different types of power stations
Kunc, Dominik ; Bartošík, Tomáš (referee) ; Mastný, Petr (advisor)
The main subject of this work is to compare the ecological impacts of different types of power stations, to describe the possibilities how to reduce some of their harmful effects, and to design a cleaner electricity production process. Firstly the summary of this paper structure is introduced and the choice of its subject is explained. The second part describes the structure of energy mix in the Czech Republic in 2009 and in the following subheads there are defined basic principles of the particular power stations’ functioning, harmful effects rising during their operating and their impacts on people and the environment. There is the evalution of the power plants that created the indispensable amount of electric energy in 2009, which are: thermal power stations (mainly coal-fired ones but also the power plants burning biomass and the gas power plants), nuclear power plants, water power plants, wind power plants and solar power plants. Further there is mentioned the economical demand of energy generation from various sources and thein potential in our country in the next years. In the following part is focused on the possibility of reducing harmfulness in present electricity production, to the reduction of carbon dioxide emissions. It briefly describes the influence of this greenhouse gas on warming of our planet, what methods of capture carbon dioxide are recently available, what are the principles of these methods and what are the possibilities of carbon dioxide storage and transportation. Then we sum up economic demands of power production in the relation to useage of these technologies in various types of power plants. Likewise the possibilities of their realization in the Czech Republic are discussed. At the end of the second chapter we estimate the change of energy mix in the Czech Republic as a possible reduction of detrimental effects created by electric power production. In the third part we classify and compare these harmful impacts. Last chapter is focused on the evaluation of our energy mix estimation.

Study of connectivity for PV power station
Krejčí, Tomáš ; Bartošík, Tomáš (referee) ; Mastný, Petr (advisor)
Bachelor‘s thesis focused on studying connectivity of PV plant into the distribution system.. The first parts are processed by the conditions of connection of new resources into the distribution system with a focus on photovoltaics. Individual points are taken from the rules of the road grid, which gives the Energy Regulatory Authority. In the second part is given FVS problem. There is a brief history of photovoltaics. More details are described photovoltaic element, its principles, and different types of PV article composition PV panel. There are presented methods of operation FVS. The last section is designed to PVP via PC software.

Possibilities of Using Thermoelectric Converters in Power Industry
Halas, Miroslav ; Bartošík, Tomáš (referee) ; Macháček, Jan (advisor)
This thesis deals with thermoelectric transformers and their application in electrical power engineering. First, a theoretical overview is shown within which major personalities of the thermoelectric field are presented. Then, construction, functionality and fabrication materials of the thermoelectric transformer are outlined. The next part covers utilization of thermoelectric transformers within electrical power engineering through the history up until now. Also major world-leading companies are presented. In the practical part, the possibilities of thermoelectric transformers in conjunction with primary power sources are shown. Then, power output of solar thermoelectric transformer during winter is calculated using balance methods. At the end, a design of thermoelectric transformer exploiting waste heat of coal power plant and its rate of return are presented. In the conclusion, findings made during this study are summed and a complex assessment of the topic is done.

Household heating systems
Ševčík, Ondřej ; Bok, Jaromír (referee) ; Bartošík, Tomáš (advisor)
Main goals of this bachelor thesis are economic evaluation of four chosen technologies of heating, and heating system design. Introduction deals with problem of heating in a family house, types of heating systems and main influences affecting the choice of heating system. The third chapter discusses main components of heating systems. Each component of the system is characterized and described. The most important parts include heating source, which are divided by type of fuel. The fourth chapter describes other possibilities of austerity meassures, which reduce heat loss and heating costs. There is a mention about government subsidies. The fifth chapter shows the shares of different heating sources, that are used in residential houses. In the last chapter, the computation of heat loss in the particular object is done. Based on the heat loss computation floor and radiator heating system is proposed. Four heat sources are chosen for the object (gas boiler, heat pump, biomass boiler and electric boiler with acumulation tank) and the purchase and the operating costs are computed. Conclusion of the chapter is devoted to the economic balance of the four heat sources and their comparison in the return of investment.
