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.

Modern approaches to designing electrical equipment with a focus on railway construction
Forejtník, Jan ; Pěcha, Jiří (referee) ; Bátora, Branislav (advisor)
The topic Modern Approaches to Designing Electrical Equipment with a Focus on Railway Construction responds to the decision of the Government of the Czech Republic to introduce the BIM method for government over-the-counter contracts from 1 January 2022. The government evaluated the BIM method as an effective tool for digitizing the construction industry. The diploma thesis deals with the method of designing high-current equipment, technologies and distribution on railways according to this new method. The work summarizes information about the present method of design, used high-current electrical equipment on the railway, the near and distant future of railway operation, the organization of administration and maintenance of equipment. It discusses the principle of the BIM method and basic software solutions supporting design activities according to this new method. The Promis.e software published by Bentley is also described in detail, which supports the design of electrical equipment for linear structures according to this method. The BIM method is a means of fulfilling the essence of Construction 4.0. It uses uniform data formats, a common data environment, working with non-graphic information. In the second part of the diploma thesis, the drawing documentation for the sample project of high-current distribution of the railway station was prepared. It was first created using AutoCAD software. After that, the sample project demonstrates the basic principles of the BIM method using Promis.e software. Furthermore, this project is evaluated, both methods of design are compared. The procedure of introducing the BIM method for the design of electrical equipment in a specific design company is proposed and other possible steps in working with the Promis.e software are discussed. The way of creating a and adding element libraries is described. At the end of the diploma thesis it is stated that to successfully master the design work according to the BIM method, it is necessary to have experience with design work in the field, know the principles of the BIM method, choose a suitable software solution, continuously and thoroughly manage these tools and train staff. Under these conditions, it will be possible to make full use of the potential of the BIM method.

The assessment of connectivity 138 MW combined heat and power plant in Prostějov
Vacek, Tomáš ; Opat, Jaroslav (referee) ; Bátora, Branislav (advisor)
The goal of this project is to test the possibility to connect the Cogenerational generation of power 138 MW (still in the development stage) to the control room 110 kV in Prostejov production. This merge would product the electrical energy as well as the heat energy for all local area. In this dissertation we will be considering the solution of the steady state (stationary state) of system with the voltage level of 110kV, as well as the influence of the generation of power on this system, there by the suggesting a connection. The Congenerational production indicates higher effectiveness in the transformation of energy during primary production process due to the production of heat energy as well as the electrical energy from the primary power sources. In our country, as well as around the world, commonly used fuels are fossil fuels- coal, crude oil, and gas. As the demand for energy grows, those supplies are slowly running out. Not to mention that those fuels have a negative environmental impact. They are a source of carbon, which causes damage to the atmosphere and leads to global warming. Power plants which do not produce carbon are much safer for the environment, and much more productive. However, the residue of this energy is challenging to dispose of. Nuclear energy has common attributes with renewing the sources of energies that are extremely friendly to our environment. Nuclear power plants also produce enough energy and with the usage of Fourth generation reactors, they will be able to recycle the nuclear fuels. Today, more importance is put on renewing sources which are more gentle for the environment. In the near future, CEZ Company, the largest producer of electric energy is planning to use water energy. Water energy comes from water plants or dams. Other ecological forms of energy include geothermal and solar energies. These two types of energy are not as applicable for our geographical position. Geothermal energy is commonly used on islands where there is an abundance of natural hot springs. The most discussed source of energy is bioenergy. It uses natural wood sources, recycled wood products, and applies bioenergy as a main source for thermal power plants.
