Thermodynamic cycles used in power engineering
Suchomel, Josef ; Kracík, Petr (referee) ; Baláš, Marek (advisor)
Power engineering is one of the most important parts of industry. Among other things, it deals with production of electricity, without which many of us can no longer even imagine life. All energy devices can be described on the basis of different thermodynamic cycles. And with these thermodynamic cycles this thesis deals. It lists both, the most important cycles, such as Rankin Clausius cycle, which is the basic cycle of most of the power plants, as well as less known, resp. almost new thermodynamic cycles. The emphasis of the whole work is also focused on the advantages and limitations of the stated cycles and on their application in practise, too.

Design and Realization of Mobile Photovoltaic Power Station
Lednický, Ján ; Morávek, Jan (referee) ; Baxant, Petr (advisor)
This diploma thesis entitled Design and realization of a mobile photovoltaic power plant is dividet into two parts. In the first, theoretical part one can learn about the state of representation of renewable energy sources in the field of electrical power engineering and about the structure of photovoltaic power station systems. The secont part of this thesis is focused on the own design and realization of the mobile photovoltaic power plant, on the selection of individual suitable components and ther dimensioning. In addition, a model of a mobile power plant has been created, on the basis of which the power plant was constructed. Finally, one can find a source code analysis of a power plant monitoring using a microcontroler

Risk Engineering in Czech Power Engineering
Míčková, Petra ; Krebs, Zbyněk (referee) ; Toman, Petr (advisor)
The work focuses on risk management in the Czech power engineering, introduces its functioning and connections. It also explains some of the general principles of risk management, its importance in the energy sector and energy projects. Selected risk management methods are described, which is the basis for the recommendation of one of them for application in the field of power engineering. The selected method is further demonstrated in the example of power energy project and its enhancements are proposed.

Advanced Stochastic Programming Models in Power Engineering
Pavelka, Ondřej ; Štětina, Josef (referee) ; Popela, Pavel (advisor)
This diploma thesis applies stochastic optimization in the field of the power engineering. In the thesis first part, the needed mathematical theory is described, specifically mathematical, linear, nonlinear, integer and stochastic programming. The second part deals with the heating plant, in which heat is generated by gas and biomass boilers. The aim of this thesis is to design a model for the schedule planning of these boilers. The model is based on two stage stochastic programming with scenario approach. Then the model is solved by GAMS software. In the final part of the text, the focus is on the model sensitivity analysis and suggestions for future improvement.

Conceptual design of secondary and tertiary circuit for a new nuclear source
Valíček, Roman ; Kracík, Petr (referee) ; Milčák, Pavel (advisor)
The aim of this thesis is to create a conceptual design of the secondary and tertiary circuit of a new nuclear power plant in our country, which is preceded by a brief search of particular generations of nuclear reactors. The VVER-1200 reactor became the model for the new nuclear power plant. There was designed a heat diagram containing primary components in this work. After that, there was the balance calculation and calculation of parameters of the main devices of the proposed scheme such as condenser, low-pressure and high-pressure regeneration exchangers and steam generator.

Use of the MAWIS Photo solution for data collection and creation of 3D building models
Viktorin, Tomáš ; Wasserbauer, Vojtěch (referee) ; Ptáček, Michal (advisor)
This bachelor thesis deals with the use of the MAWIS Photo service for data collection and creation of 3D models with a specific focus on cable routes. In this context, the thesis provides a basic overview of the legislation and technical standards relevant to the implementation of projects and the control of cable route construction. It also focuses on a detailed description of the MAWIS Photo web application, including it`s usability, basic principles of operation, advantages and disadvantages. The thesis also discusses GIS systems and surveying in relation to energy construction. In the practical part of the thesis, the applicability of the application in practice is verified, specifically the description of the measured cable route, measurements, creation of a 3D model of the structure, subsequent creation of drawing documentation and evaluation of the achieved results. Following the direct experience gained with the use of MAWIS Photo application, the thesis also provides a critical evaluation of the applicability of the application itself in the practice of power structures.

Design of a micro waterpower turbines for low head and low dicharge
Macek, Libor ; Fic, Miloslav (referee) ; Štigler, Jaroslav (advisor)
This diploma thesis discusses the issue of finding type of water turbine for very low heads and low discharges, which could be operated as mobile micro hydropower plant in island mode. Thesis deals with summary of appropriate choices of water turbine for needs of micro hydropower plant. Essential part of diploma thesis deals with design of optimized waterwheel. Waterwheel was chosen because commercial high-speed turbines have low efficiency for low heads. Waterwheel was manufactured and measured in laboratories of Fluid engineering. Measurement output was discharge and efficiency characteristic of turbine. The price calculation was made after manufacture.

The tooth pump in the turbine regime
Tyburec, Adam ; Dobšáková, Lenka (referee) ; Haluza, Miloslav (advisor)
The objective of this diploma study is to develop and secure production of gear turbine with very low specific speed in comparison with conventional turbines. The first part of the work deals with already performed research of similar hydrostatic turbines. It is followed by construction design, including complete drawing documentation. The production of the prototype is secured by an external company. Finally, an experimental measurement of the characteristics of the designed turbine is performed in the laboratories of Fluid Engineering.
