System wiring and the power balance
Horenský, Martin ; Bátora, Branislav (referee) ; Macháček, Jan (advisor)
Bachelor thesis deals with the theoretical part of the general problem of system wiring. The introductory part includes a general introduction. Gradually are described differences from classical wiring, to compare the advantages, disadvantages and cost. Shortly is described historical development from the first attempts to currently solution used by manufacturers. Subsequently used systems are divided into several groups and described. In the next chapter is performed research most famous electrical system from different manufacturers. In thesis there are described systems iNELS and Ego-n in detail. For each system are described basic functions, linking structure, used bus, the method of programming, a summary of advantages and disadvantages. In addition is made a brief description of system components. The practical part is focused on establishing own consumption of system wiring components in the model family home. Calculations and measurements are performed for three systems - iNELS, Ego-n and KNX. First, there are designed requirements that should meet the installation. Based on the requirements is created list of components of the systems installed - for each installation according to appropriate system.. From technical catalogs are designed theoretical input powers of each installation. The following is a test procedure for measuring educational panels. Results of measurements are processed and compared with catalog data for each component. In addition input powers are calculated from individual installation measured values. Results obtained from the measured and theoretical data are compared. From the each calculated power consumption is determined annual payment for consumption the system wiring. For each measurement system are recorded and reported data transfers through the bus. A complete evaluation of the results is shown in conclusion.

The use of advanced composite materials for the design of concrete structures
Macháček, Jan ; Matušíková, Anna (referee) ; Girgle, František (advisor)
The diploma thesis deals with the design of concrete structures reinforced by FRP according to ACI, fib, CSA and EC2 regulations, which are stressed by a shear force. The diferences between steel rebar and FRP reinforcement were described, in particular its mechanical degradation over time and a different stress-strain diagram. Furthermore, shear capacity calculations were performed according to the regulations and compared with the real tests. Then the parametric analysis of shear strength was performed. In the practical part, the design of concrete floor slab structure supported by the pillars and walls was performed. The upper reinforcement of this slab was designed with FRP and the lower with steel rebar. Double-headed studs were used as a punching shear reinforcement.

Economical appraising of run the power from cogeneration units to different voltage level
Doležal, Václav ; Macháček, Jan (referee) ; Baxant, Petr (advisor)
The topic of the thesis is economical appraising of run the power from cogeneration units to different voltage level. There is sloves in the text, how and under what conditions we can find an optimal solution for the deployment of cogeneration units to the electricity network. The main criterion is the loss of networks and their economic evaluation. We are a description of the different types of cogeneration units, the economic balance and a treatise on losses in electrical networks.

The price of electricity and the choice of appropriate distribution rate
Hromek, Lukáš ; Ptáček, Michal (referee) ; Macháček, Jan (advisor)
This work is focused on the price of electricity, components that compose and factors affecting this price. Includes brief overview of energy legislation, namely to the rights and obligations of distributors of electricity, energy traders and customers. Furthermore, the work deals with the researches of the energy market in the Czech Republic, the different rates of selected suppliers and evaluating their suitability for the customer.

Design and computer control of intelligent wiring system Ego-n
Hubálek, Michal ; Macháček, Jan (referee) ; Bátora, Branislav (advisor)
Bachelor thesis addresses the issue of smart wiring for household management. It is focused primarily on the modern system of Ego-n by ABB s.r.o., which is commonly available on the Czech market. It first explains the differences among individual intelligent electrical systems that are used here in our country. These systems are divided into groups and briefly described. This is followed by an introduction into the Ego-n system, formulation of basic principles of the system, its capabilities and applications. Most of the work is focused on the production and "Revival" of the laboratory panel of intelligent electrical set Ego-n. Laboratory panel is to demonstrate the functions of controlling the lighting, blinds, heating and other circuits. Programming of the laboratory panel can be manual or made by computer. For both options there are laboratory instructions written for practicing the various functions. The work also includes budget and a list of materials for the manufacturing of the laboratory panel and its wiring.

Calculation and design of electric underfloor heating according to CSN
Urbánek, Jaroslav ; Šlezingr, Jan (referee) ; Macháček, Jan (advisor)
This thesis deals with the issue of electric underfloor heating and various types of heating elements such as heating cables, heating mats and heating foils. The thesis also contains elements that are important in the implementation of underfloor heating. Part of this work are listed standards addressing the issue of underfloor heating. In the final part there is a proposal of underfloor heating and photovoltaic system for a family house with the economic evaluation as an integral part of the issue.

Remote control and visualization of bus-systems KNX and DALI for building management
Holub, Jiří ; Macháček, Jan (referee) ; Bátora, Branislav (advisor)
The thesis is focused on bus systems and their control by GUI. Basic energy management principles and the mostly known bus systems are analysed in the first – theoretical part of the paper. The theoretical part is then focused on software tool ETS 4, which is used for activation of system installation KNX. Software tool SmartServer, which is used for communication between bus system KNX and web interface, is described at the end of the first theoretical part. Two laboratory boards assembled of KNX and DALI parts were constructed in the second – practical part. Three laboratory tasks, which are prepared so they are related to theoretical description in previous part, were submitted in next step. Aim of the first task is to introduce basics of the board and PriOn interface. The second task is focused on DALI components and temperature control with PriOn regulating device. Creating of basic visualization and controlling of the board with SmartServer is described in the last task.
