Utilization of biomass for small business or houses
Láník, Lukáš ; Šlezingr, Jan (referee) ; Macháček, Jan (advisor)
Thesis deals with usage of biomass as an energy source for smaller plants and houses. Thesis showes us how to use different types of biomass. In the next part of thesis is mentioned the help from the state in case your are using this kind of energy, different types of dotations ane advantages. In the thesis is described the procedure of designing nex heat source and making decision about it. The last part of thesis compares the economic running boiler on land gas to boiler of different kinds of biomass.

Construction of sample exercises for model of systems wiring
Pěcha, Jiří ; Bátora, Branislav (referee) ; Macháček, Jan (advisor)
In this thesis explains the term of systemic wiring and its spread in the Czech Republic. It is written a brief overview of manufacturers which are interested in this area. Comparison of advantages and disadvantages with classic wiring. For further meeting is suggested a laboratory panel which contains instruments from company ABB which belongs to international group Konnex. At the concussion of this thesis is created demonstrational application for controlling of instruments.

Using Biomass for Cogeneration of Heat and Electricity
Vašíček, Martin ; Macháček, Jan (referee) ; Toman, Petr (advisor)
Theoretical part is concerned to disposal of biomass kinds and various forms of applications. The basic characteristic for each kind of biomass and their forms are presented. Characteristics of energy plants and woods are more detailed. In work are described two fundamental kinds of combustion, fluid combustion and grate combustion, which are used in power plants and heating plants. The work describes process of gasification and obtaining wood gas from biomass. Evaluation of (energy plants, wood biomass and the rest from agriculture production – straw) in light of heating power, treatment, handling, ash creation and environment pollution is provided. Work is concerned to redemption price history, volume of produced biomass and perspective to future. Czech Republic legislation gives support to biomass usage by guarantee for electric energy purchasing and same redemption price perspective. Explain term of cogeneration, possibility of cegeneration units application – their kinds with fuel usage aspect (biogas, natural gas, wood gas). Practical part is concerned to design of such kind of unit. Cogeneration unit will be installed in company, which producing wood. For this reason will be used wood biomass to produce wood gas. Size of unit, fuel consumption, and cost saving in comparison to electric energy together with recovery of investment are calculated. In work is drawn out possibility to connect this unit to distribution electrical network, possibility of electric energy distribution and due this to improve backflow. Noticeable are possibilities to get state grant from various grant sources.

Using of Renewable Energy Sources for Family House Supply
Varmuža, Jan ; Macháček, Jan (referee) ; Toman, Petr (advisor)
This work is concerned to analysis and evaluation of present recoverable energy resources and position EU to them. In study is provided comparison of recoverable resources (biomass, water, wind, environment energy, and sun). The details are noted for all single cases. As the next addition are included various techniques „how to obtain and convert them“. In study are also noted which necessary equipments must be used and their proper location. In practical part is done comparison of barrier-layer photocell from polycrystalline and monocrystalline silicon and water insulating foil „EVALON SOLAR“. For comparison was taken only produced energy. Next step was financial analysis of each single system and comparison with pay-off in case that invested sum (actual price) was placed to bank under time deposit and share capital fund. During analysis of financial evaluation was found, that more suitable is system from polycrystalline silicon. Because of investors main condition is financial aspect, so for realization will be recommended system from polycrystalline silicon.

Computer controled inteligent elements of electrical instalation
Kolář, Milan ; Macháček, Jan (referee) ; Bátora, Branislav (advisor)
This bachelor thesis deals with the field of intelligent wiring. In the first part, there is an explanation of how the inteligent wiring works, its main parts, topology and categorization. In the second part, there is an example of practical application which is built on the elements of the INELS system. There is also a comparison with the classic (conventional) wiring. It is followed by programming and setting up of the wiring with the included software IDM. Finally, there is an example of visualization, a possibility of remote control and function management with a data net.

Electrical installation in family home
Pokorný, Marek ; Bátora, Branislav (referee) ; Macháček, Jan (advisor)
The goal of this bachelor paper with the topic " Electrical installation in family home" is to describe laws and public notices that relate to an electrical setting; relevant norms and conditions for a connection to a distribution network (low tension service lines); ways of connections and its location. Furthermore, this paper describes operational conditions, external effects, dimensioning, cabel lodgements and protection (its ways, principles, security and conductor). In a separate chapter low tensinon switch-boards distribution and its instrumentation is covered. Another sphere of this bachelor paper is the field of illumination and lamps. The following chapter deals with sorts of electrical setting (classic, intelligent), low-tension electrical setting (PC distributions), fire and safty electrical setting and audit report elaboration. A practical sample of a electrical installation in family home is shown at the end of this paper

The project of model hydroelectric power plant
Urbánek, Jaroslav ; Macháček, Jan (referee) ; Radil, Lukáš (advisor)
Master thesis consists of the construction of a small hydroelectric power play model for laboratory use. The first step is to calculate parameters required for the creation of the 2D model Banki turbine. Next part is a proposal and selection of individual components of the model, such as generator, turbine housing, water circuit, pump and alternator mounting. The last step is to launch the model and verify, if the model of a small hydroelectric power plant achieves the required parameters.
