A multi-source power station switch- and control-boards digitization project
Fiala, Martin ; Bátora, Branislav (referee) ; Drápela, Jiří (advisor)
This bachelor´s thesis deals with comprehensive proposal and reconstruction of switchgears for source power station on Department of Electrical Power Engineering with controlled rotating and static power sources, that can be managed remotely using a programmable logic controller via the communication link. Part work also description of the control system and all the necessary parts for reconstruction. At last this thesis deals with the problem, which is linked to the deployment of automation in general, including the negative aspects, describes the problem of industrial communication systems along with the most used fieldbus that is used in the implementation of automated solutions.

The Project of Computer Network
Havlík, Kamil ; Šedivý, Karel (referee) ; Ondrák, Viktor (advisor)
This project aims to create a complete proposal for a computer network for Autodružstvo Znojmo. Proposed solutions must take into account the current technical and safety trends that are valid under the relevant norms and standards for the type of Gigabit Ethernet network. The work will also described the use and characteristics of individual sub-components, which are for the operation of the entire network is necessary.

Analysis of effects of short-circuit current in switchgear cabinet
Prokop, Jan ; Bušov, Bohuslav (referee) ; Valenta, Jiří (advisor)
The work is focusing on dynamic effects of short-circuit currents, more precisely dynamic effects of short-circuit currents on switchgear cabinet (terminal box). The work was designated to a concrete construction type of two switchgear cabinets located on rotating machines via company Siemens Electric Machines Drásov s.r.o.. The switchgear cabinets are designed for non-explosive environment where the air is used as an insulating medium. The task was to determine how the device will behave during the three-phase short-circuit and three-phase short-circuit with earth/ground connection. The following programs were used for the calculations and simulations: Ansoft Maxwell 16.0, Ansoft Maxwell 2015 and ANSYS Workbench 16.0. By using these programs the effects of forces which acts on current paths in cabinet caused by the passage of short-circuit current were simulated, statically and also dynamically. Further the effects of pressure acting on cabinet frame during the arc short-circuit have been statically and dynamically simulated. All the results are summarized in the conclusion. Conclusion also contains the final evaluation of the functionality of both switchgear cabinets.

Design of 22 kV Cable Network in the Existing Complex of Faculty Hospital
Blažek, Tomáš ; Procházka, Aleš (referee) ; Orságová, Jaroslava (advisor)
This thesis describes the reconstruction network 10 kV HV networks in a teaching hospital in the transition to a new 22 kV voltage level according to valid regulations. The paper describes the current state of technological equipment and its gradual replacement with new technology at 22 kV voltage level in each power units so as not to limit the operation of the hospital. For this purpose, the new backup system for rotating spare resources. The thesis deals with new input distribution, which will serve as a transfer point between the customer and distributor of electricity as well as advance the existing technological equipment.

Electrical Installation Project for Kindergarten
Macků, Dominika ; Bátora, Branislav (referee) ; Mastný, Petr (advisor)
The work has three main parts. The first part of the thesis introduces the problems of power and data installations to the reader. This includes related legislations, LPS, the methods of feeding the building by electrical power and the electrical wiring in the building, including their execution and protection. In the second part of the thesis are defined the principles of creation of electro design documentation. Mainly the requirements for their content and editing. An important point is the process of creating a design. The last part is practical. It is the elaboration of a complete wiring design of the kindergarten building, which consists of drawings and technical reports.

Project of Outgoing Transformer Unit for the Photovoltaic Power Station
Hanák, Miroslav ; Procházka, Aleš (referee) ; Orságová, Jaroslava (advisor)
This master’s thesis engages in project of outgoing transformer unit for the photovoltaic power station. It describes project and its design documentation what conducts to practising of construction. It has compared investing to more expansive transformer what has lower loss. It describes charges of operation’s transformer in twenty years. It leads project of cable low voltage. It compares whether is better to use aluminium or cupric cables. Project is led with respect for investment costs and minimum of operation loss.

Documentation for construction of new distribution transformer station and cables line HV a LV
Matouš, Milan ; Orságová, Jaroslava (referee) ; Bátora, Branislav (advisor)
The following master thesis is devoted to the design of distribution systems of LV (Low Voltage) and HV (High Voltage) voltage levels. The aim of the thesis is to create a complete project documentation for the construction of a new distribution transformer station (22kV/0.4kV) situated directly in the city of Blansko along with a transformer capable of performance of up to 630kVA. Subsequently a design of cable routes of LV and HV is included in the project documentation. The first part of the thesis introduces the fundamental issues and solutions regarding the design of electrical equipment related to the LV and HV voltage levels. Thereafter it deals with proper legislation, technical regulations and related standards. The second part is dealing with project documentation. More precisely analyzing each step in the process and thoroughly going through individual parts of the project documentation. Other focus of the thesis is software resources and tools which are essential for drawing documentation. Then follows a selection of appropriate electrical equipment and budget evaluation. The major portion of the work is a design of distribution transformer station and cable lines of LV and HV. Including dimensioning of the LV and HV switchboards, earthing system and fuse protection system. The essence of all this work serves as a foundation for complete design documentation.

The project of computer network for the boarding houses Juventus
Musil, Martin ; Šebeček, Petr (referee) ; Ondrák, Viktor (advisor)
This baccalaureate work will deal with the of computer network for the boarding houses Juventus in Brno. Here will analysed the building of boarding houses, organizations number of employess , his needs and requiremnts, budget, number of housed. In next parts is introduced how has network look and theoretic data solving. In this thesis is proccesing proposal of cabling system. One part of proposal will be selection another componets of net (passive or active). In the last part of my thesis is analysing this problem in practice and economic situation for company.

Electrical installation in family house
Tesař, Jan ; Procházka, Petr (referee) ; Ondrejček, Vladimír (advisor)
This Bachelor Thesis is concerned with the design of the electrical installation of a family house. There are two main parts of the thesis – theoretical basis and the main design. In the theoretical part the reader is at first introduced to a powerline section, in which the electrical installation from the powergrid to a terminal equipment is described. Next part is about a low voltage wiring, where the commonly used types of wiring and devices are described. In the third part the reader can read about a lightning protection and its inner and outer parts. The main design consist of situational designs of devices and wiring in the house, switchboard designs, revision of the electrical protection and the technical report.
