The Economic Effectiveness of Wind Power Project
Vániš, Jiří ; Radil, Lukáš (referee) ; Macháček, Jan (advisor)
The following text is devoted to wind power stations. It shows basic distribution of wind engine according to the principle of their function and suitability of their use for power generation. It shows the parameters that must satisfy the suitable sites for building wind power stations and it shows wind maps of the Czech Republic. There are described some of the most frequently installed machines in the Czech Republic. Next chapters describe the economics running part of wind power stations; analyze the basic cost-sharing, mention methods of tax depreciation of tangible assets, the redemption value of electrical energy from renewable sources. There are chosen some of the most used methods for assessment the economic efficiency of wind power stations. There are common methods of static and dynamic in terms of time value of money, the possibilities and limitations of their use. This information is a basis for designing and implementing a program to calculate the economic efficiency of wind power station. The goal is to create a computer program based on your input values and calculation methods to calculate the economic indicators and economic effectiveness of project wind power station in terms of total investment coasts and on equity capital projects. Based on evaluation of data it will be ready to determine whether the investment in to the construction of wind power station can provide the required funding.

Markets and Electricity Trading from Renewable Sources in EU
Pěcha, Jiří ; Čambala, Petr (referee) ; Macháček, Jan (advisor)
The submitted diploma thesis describes particular types of European energetic exchanges, focuses in depth on principles market in Czech Republic and studies the price development on spot and futures markets. The main idea of this work is to focus on renewable energy sources (RES) and their influence on energetic markets. At first, operational and reliability properties of RES are explained and then their development support is analyzed. Last chapters focus on how the power grid is impacted by RES that are hardly predictable source with local production characteristic. There are also outlined problems originating from irregular production that are linked to a surplus of electric energy, but also on energy shortage caused by bad weather. These problems influence international commerce and reduce the capacity of cross-border profiles.

Design and production of sample panels with system installation Inels
Steidl, Jaromír ; Bátora, Branislav (referee) ; Macháček, Jan (advisor)
Diploma thesis deals with the problems of system installations. The system installation is presented as an installation, where the light switch does not serve for interrupt a power circuit, but it serves as a sensor, which directs the status change of actuator, that makes the own manipulation with a power circuit. In the first chapter the diploma thesis presents the history of the system installation development depending on the demand for the system regulation in buildings centrally and complexly. There are also summarize advantages and disadvantages of installations, which are used in these days. In the second chapter, the system installations are devided into centralized and decentralized systems. The centralized systems are constructionally simpler as well the communication, but the whole system is more inclinable to fail. The decentralized systems are more complicated, more expensive, but more reliable and they have also potentiality to extand. Two decentralized systems, nowadays the most used, are further presented – KNX and LonWorks. They are used especially for the administration buildings control. Then the diploma thesis presents both some systems, which are used abroad, and the situation at the Czech market, whereas there is described the system INELS, which is made by Elko ep. Limited Company. The goal of the thesis, which is mentioned in the third chapter, is to present the system installations, design a panel with this installation including the panel´s handmade, and then on this panel demonstrate the panel´s using for education in laboratory practices. The fourth chapter discusses the author´s characterization of the panel´s concept – there is described the graphical concept of the panel, used units and their integrations. By all of used units their functions on the panel are described. In the last but one chapter, there are mentioned the practical applications, which the panel serves, and there are also described the concepts of laboratory tasks for education of the fundamental configuration and possibilities of the system installation INELS. The chapter also engage in the configuration of the system for the panel, which presents control elements in one room via the system installation INELS. This configuration serves for the presentation of the educational panel. The conclusion is dedicated to the summary of the mentioned problems.

Design and production of sample panels with system installation Ego-n
Vašíček, Martin ; Bátora, Branislav (referee) ; Macháček, Jan (advisor)
The thesis deals with the development of systems for intelligent building, focused on wiring system, division of them and comparison of their differences. The advantages of these systems like comfort, energy reduction, etc. are also mentioned. Nowadays several standards of systems for intelligent building exist as KNX/EIB or LON, therefore thesis concerns to trade-off these standards too. Main part of the thesis is focused on system Egon made by company ABB where the system concept as well as bus modules are described that allow different functions, mutual connection of modules and their programming. Tutorial panel with ABB Ego-n wiring system, which will be used for study purpose, is designed in the practical part of the work. It includes scheme of the panel, electric linkage of components and photographs of constructed panel as documentation. In the final part of the work two examples of laboratory exercise for installation and setting are listed, including programming description.

Classical versus intelligent electrical installation
Haluza, Miroslav ; Brázdil, Vlastimil (referee) ; Macháček, Jan (advisor)
This work topic is development and history of intelligent wiring systems in Czech Republic as well as abroad. The firs paragraphs describe following: intelligent wiring systems, the differences between classic and intelligent wiring systems and consequently is described the intelligent wiring system itself (types, principles, advantages, disadvantages etc.). Detailed description of system Inels follows in the next chapters. This system is supposed to be the fundamental matter of this work and is used in consequent suggestions for intelligent wiring system that is defined at the end of the theoretical part of this work. At the conclusion the economic evaluation of various wiring options and assessment by the multicriteria analysis (MCA) will be provided.

Economic effectiveness of systems wiring
Jorda, Martin ; Bátora, Branislav (referee) ; Macháček, Jan (advisor)
This master’s thesis tries to show the differences between usual obsolete indoor wiring and clas-sic indoor wiring used these days and also between this „classic“ indoor wiring and „intelligent wiring“. There is insisted on selection and optimalization of the adequate system for a concrete building and there is made a question of specifications of the user or the customer, his preferen-ces (financial, space, family etc.), disadvantages and advantages of the current system. Whereas it’s impossible to satisfy all the users in these problems by reason of diversity of the buildings (it can be a lot of variants of family houses or small apartments), the systems in this thesis are ap-plied only on the most frequent types of houses. Quite lot of firms deal in this country with indo-or wiring, the most known are ABB, ELKO EP and Moeller. Each of these firms offers different alternatives of systems. From the simplest, basic alternative, to most sophisticated „intelligent“ systems, which can care about almost everything, what is common with electrical energy. These different systems, their review, advantages and disadvantages are also presented in this work. Preliminary there is analysed the whole issue from the historical view and there is briefly explai-ned, what the system wiring is. In the next chapter there is a complex description of the actual state of known firms and systems on the present-day market in our country and in the world. The-re is also summarised the basic structure and the overall comparison of the most frequently used bus systems. In the next two chapters there are presented the main objectives of this work and the methods and procedures, how to achieve these objectives. The central part of this work is the next to last chapter, in which there are presented the different model variants of the project, applied to the real residential building - middle-sized family house. That is realized on the basis of the spe-cified requirements on the designed system. Before that there was performed the complex design of the situation scheme of all usual electrical appliances and lighting system in the house. In the end the whole work is in summary analysed, mainly in term of costs of each variant of the pro-ject. By virtue of this can the reader make a better view about the whole financial problem of the system wiring, that means, how much he has to invest in his concrete wiring. In the end of the work there is attached the detailed documentation to all alternatives of the project, such as dra-wings (complex horizontal plans) and costs budget of all used items and the wiring material.
