Conceptual design of the reconstruction of an E.ON 22 kV distribution network installed at a specic area
Vepřek, Tomáš ; Nepevná, Vlastimila (referee) ; Blažek, Vladimír (advisor)
The aim of this thesis is a modification of the distribution network (DS) of the city of Brno to ensure power supply in the required quantity and quality for end consumers. Calculation of steady - state operation of distribution network (DS) of Brno is performed in the programme PAS DAISY Off-Line v.4.00 Bison. On the basis of available data (dispatching scheme, load current of stem lines and reserved power of wholesale customers) we will analyze the steady-state of network. We will find out which of the 110/22 kV transformer stations, cable and overhead lines are overloaded and perform network adjustments to ensure safe and reliable operation by 2015. We will identify in which year we will need to build a new power node in the northern part of Brno. The conclusion is focused on technical and economic evaluation of proposed alternative network arrangements.

Technical and economic comparison of electrical system designs of the hotel complex
Šedivý, Tomáš ; Jurák, Viktor (referee) ; Ptáček, Michal (advisor)
The aim of the bachelor thesis is to implement the designs of electrical power supply of a selected hotel complex and related technical and non-technical comparison. The subject is specifically to compare the power supply solution options through a centralized power centre, separate transformer stations located within the complex, for example in terms of the evaluation of active power losses on the line, investment and operating costs or in terms of space requirements, etc.

Construction of conduit of technical equipment in the municipality
Hrachovinová, Petra ; Kučera, Tomáš (referee) ; Raclavský, Jaroslav (advisor)
This bachelor´s thesis deals with a technical equipment in an urbanized area, especially with underground lines of 3rd and 4th category (according to the Czech norms). The theoretical part consists of research of species, methods, principles of conduction and connections, and materials of underground lines. In the practical part, there are applied basic gained knowledge for a construction of technical equipment in the development location in a village called Náklo.

Radar antenna diagnostic module
Pacner, Petr ; Urbanec, Tomáš (referee) ; Kubíček, Michal (advisor)
Faults like open and short circuit in electrical wirings pose a significant threat on functionality of the whole application. This thesis describes conceptual design of a fault identification module for coaxial cables between transmitter and antenna in radar systems, and focuses on faults localization. The main goal is to select from existing a suitable method for such faults analysis and create a demonstration module serving as a basis for further development. This contains theory regarding basic classification of wiring faults and principles of frequently used detection methods including some of their prameters, advantages and disadvantages which altogether build a foundation for method selection. The chosen method is analyzed by simulations and further on laboratory equipment controlled by a set of computer applications. In the end the chosen method is implemented on a development kit, which is then used for measurements of wire sample.

Overcurrent protection relay testing using tester TZO3.
Vavreczky, Gábor ; Paar, Martin (referee) ; Toman, Petr (advisor)
The main task of this bachelor’s tesis is testing digital protection 7SA610 from Siemens. Purpose of the project is to take up with overcurrent functions of the protection, and realize it's testing through secondary tester TZO3. For this, the project grants theoretical foundations: deals with basic fault conditions in electrical networks, in detail describes the principle of individual types of overcurrent protections, grants informations about the used tester and about the used protection. In the final section of the thesis suggests applicable laboratory task in teaching at Department of Electrical Power Engineering, based on performed tests.

Multi-Conductor Model of Communication over Outdoor Power Lines
Franek, Lešek ; Steinbauer, Miloslav (referee) ; Vozňák, Miroslav (referee) ; Fiedler, Petr (advisor)
PLC - power line communication is not new. It has been known for many years. But It never be used in massive scale. There were only sporadic applications, for example ripple control system HDO used in the Czechoslovakia. PLC currently experiencing a renaissance thanks to the advent of Smart Grid. PLC offering relatively low bit rates and relatively unreliable transmission, but these disadvantages compensates very low costs to build a communication infrastructure and it offers specific functionalities for Smart Grid. The question is whether the declared parameters will be met in the real world. This thesis tries to find an answer.

Power Systems Ranges of Main Parameters
Řehořek, Tomáš ; Gála, Michal (referee) ; Paar, Martin (advisor)
The thesis deals with description of the power system, parameters of it’s components and the range of outputs and consumption. In the first part the structure of the power system is described as well as the fundamental division of electric grids. In this part the work also touches on the ways of supllying the elctric traction. Furthermore the amount of production and consumption is mentioned. In the second part this work focuses on description of selected components of the power system and their real parameters. Furthermore the work also touches on the matter of electromobility and battery energy storage systems. In the last part of this work a few simple methods of consumption estimation are presented. This work also includes two infografics, that describe the power system.

Graphic Description of Electric Energy System in Selected Areas
Šácha, Tomáš ; Fiala, Zbyněk (referee) ; Paar, Martin (advisor)
The bachelor thesis deals with graphical description of power system for selected areas. Based on publicly available materials and materials provided by E.ON Distribuce, a.s., a graphic description of electricity consumption and performance of selected cities, municipalities and power lines are created. The thesis describes the structure of the power system and its main parameters, including the distribution of networks in terms of their arrangement. It also contains information on the selected municipality from the data provided by the Czech Statistical Office. Graphically processed consumption values, both selected cities and municipalities, as well as selected areas and also electric traction vehicles are shown.
