Business plan of building distribution network for company Porcelanosa in the Czech Republic
Prade, Lukáš ; Svobodová, Ivana (advisor) ; Švarc, Zbyněk (referee)
The aim of this thesis is to create a business plan for an existing company Design Bath, which operates as a wholesale and exclusive distributor of company PORCELANOSA Grupo on the Czech market of ceramic tiles. The plan is focused on building and extending current distribution network of PORCELANOSA Grupo products and should serve as a background for future decision making process and development of long-term strategy of company Design Bath. On the basis of this business plan we should be able to evaluate its feasibility. The theoretical part of this thesis contains basic introduction into business plans from theoretical point of view and market research methodology. The practical part includes the description of international and Czech market of ceramic tiles in order to understand the business opportunity. Description of competition, market research, proposal of suitable forms of distribution and financial plan are all included in the practical part in the way that the chapters logically follow each other. Financial plan revealed that the business plan is viable. Potential risks and conditions of successful realization complete the last part of the thesis.

Analysis and design of the replacement of the specific overhead line in distribution network
Račuch, Marek ; Bátora, Branislav (referee) ; Ptáček, Michal (advisor)
The diploma thesis deals with the issue of the reconstruction of outdoor cables of low voltage distribution network in exchange for the cable line. It analyzes the important factors which are necessary for the preparation of the project documentation for the issue of the territorial consent. The thesis is divided into 4 main chapters. After the first chapter there is introduced chapter 2, which shows the differences between cable and outdoor cables with their advantages and disadvantages. Chapter 3 deals with the guiding principles for low-voltage cable design and the types of equipment needed for the proper operation of a particular distribution network while respecting the requirements of valid PNEs and ČSNs. Chapter 4 explains the chronology of the process leading to the formulation of a basic technical proposal, which is further addressed in Chapter 5, which deals with the complete formulation of the project documentation for the issue of territorial consent.

Electrical installations in apartment building
Novotný, Jan ; Formánek, Marian (referee) ; Doležalová, Jana (advisor)
This bachelor's thesis deals with electrical wiring in apartment building. The aim is to describe the types of distribution networks, implementation possibilities of service lines, describe the individual parts of the wiring in the building and the principles of their implementation. Further describe basic electrical materials and to explain the design of artificial lighting. In the practical part the information applied to a particular apartment building, together with the calculation of the estimated annual energy consumption of flats. For the apartment building project is created in the form of engineering report and drawings.

MV netwok design for 75 new houses in Damborice
Makuta, Peter ; Novák, Vojtěch (referee) ; Ptáček, Michal (advisor)
Content of this thesis is medium voltage network design for seventy five houses in Damborice. At the beginning author discuss about history of transmission network and distribution network. Next topic is about steady state of network. In theoretic part are different solving methods of linear and non-linear simultaneous equations discussed. Author describes four methods – method of node voltages, elimination of balance node, Gauss-Seidel and Newton method. The electric properties of both the overhead transmission lines and cable lines and their variety are part of this work too. There is purpose, forms and parameters of transformers described. Simplicity of author’s design should reduce the usage of many electrical elements visible to residents.

Design of the distribution network branch for new family and apartment houses in Újezd u Brna
Frechová, Lucie ; Novák, Vojtěch (referee) ; Ptáček, Michal (advisor)
The work mentions the concept of present electricity networks in the Czech Republic and based on voltage levels it also describes distribution networks in more detail. Furthermore it brings the analysis of legislative conditions and technical aspects, under the rules of the distribution network operation, for new customers who require new connection to electricity network. Because of the steady-state network evaluation represents very important issue of the power system calculations, therefore it is explained in theoretical part of this work. Nowadays, Gauss-Seidel method and Newton iterative method are generally used for the steady-state analysis. Mentioned ones are also described and compared together in theoretical part. Furthermore methods are applied in practical part which solves specific configuration of the network in a given area. Moreover there are the basics of the conductor sizing in terms of the warming, both during normal operation and during a short circuit. However, it is necessary to respect other aspects of the conductor sizing, therefore issues of mechanical and electrical strength, the voltage drop and the sizing economy are also shown. There is also the characteristic of proposed and the description of the individual components which are used for the network i.e. transformation station, HV and LV switchgear, transformer, HV and LV cabling. It also concludes the characteristics of the design opportunity with their power and economical comparison.

Increasing the electric power of photovoltaic power plant connected to distribution network in a given area
Klobučník, Jozef ; Novotný, Jan (referee) ; Ptáček, Michal (advisor)
This bachelor’s thesis deals with increase of the power of photovoltaic power plant Horné Túrovce. There are two proposed possibilities how to increase the power. The theoretical introduction of the bachelor’s thesis is focused on the description of the main parts of the photovoltaic power plants. There are the technologies of the photovoltaic cells production as well as components of the photovoltaic system stated. There is further description of the photovoltaic panel’s function, principle and types of inverters, the impact of the photovoltaic power plants on the distribution network. There is the working procedure of connecting the new source and the technology of the power output to the distribution network described. The bachelor’s thesis provides technical description of the selected photovoltaic power plant Horné Túrovce and technical proposal to increase the output of photovoltaic power plant Horné Túrovce designed for both variants. The fourth section deals with methods of verifying connectivity of the photovoltaic power plants to the distribution networks and with the bad impacts on the distribution network. In the last part is a practical calculation to verify the possibility to connect production to the distribution network after the increase of the power for both variants and calculation of the bad impacts on the distribution network.

The analysis of parallel operation variants of supply areas 110 kV Čebín and Sokolnice
Reiter, Martin ; Vaculík, Petr (referee) ; Toman, Petr (advisor)
The diploma thesis is focused on the analysis of parallel operation of Čebín and Sokolnice substations. Different variants of parallel operation are researched. A calculation of steady state by the iterative method is described in the theoretical part. The next part briefly mentions a short-circuit and dimensioning of conductors. The possibility of overloading of lines and transformers is discussed in the last chapter of the theoretical part. The current state of the situation is described in the practical part. Main goal of the practical part of the diploma thesis is to design a configuration capable to parallel operation. Also another configuration of supply of this area is designed. There must be no direct connection between Čebín and Sokolnice substations on 110kV level in this configuration. This configuration should eliminate a transit flow of power. Each configuration has to fulfill the requirements on the steady state and on short-circuit current capability. One of the last chapters is focused on the steps, that should by undertaken to prevent transit flow of power.
