Modelling of energy producing system and its operation planning applying advanced mathematical methods
Benáčková, Jana ; Karpíšek, Zdeněk (referee) ; Pavlas, Martin (advisor)
This master's thesis deals with the proposal of the cost-effective biomass and coal combustion concept for a real generation plant. The optimization of the current fuel basis exploitation and annual operation scheduling was the main goal. Applying the regression analysis and stochastic programming the mathematical model was constructed based on the operating data. The overall energy source model was implemented to the concept of the optimal operation scheduling considering the economic aspects. The fuel utilization and energy production planning are the main applications of this design.

Heat layout of heating power plant with cogeneration unit 1600kWe
Buřil, Tomáš ; Kól, Přemysl (referee) ; Skála, Zdeněk (advisor)
Main target of this master´s thesis is a projection of a thermal circuit of a heating plant, which uses waste heat of a cogeneration unit with power of 1600 kWe. Electric power of a cogeneration unit is supplemented with an electric power produced from a waste heat. All heat is further used for heating in a warm water heating system. Within this thesis are executed projections of a thermal circuit of a heating plant, choice of particular devices, determination of a thermal power of devices and also determination of conditions of particular heat – transferring substances. Furthermore, design of particular devices is made, mainly for basic dimensions and heat transfer.

Contactless level measurement
Pribula, Wojciech ; Richter, Miloslav (referee) ; Petyovský, Petr (advisor)
The~thesis begins with an~analysis of~methods of~water level measurement in~high-pressure system. This~systems are placed in~heating plants and power plants and they work with the water whose temperature exceeds 300\,°C and whose pressure is above 10\,MPa. Thesis present method of~differential pressure with the~derivation of~the~correction element and also is~described capacitive method, especially Hydrastep system. This~work prepares theoretical foundation under creating algorithm for level detection using image recognition. Also it considers suitable hardware as~camera and light for illuminating and highlighting the~level. It~includes outline of~captured image editing and detection algorithm. The next part of thesis is dedicated algorithm itself. There are described classes and methods that are used for level detection or for debugging. Also, there are specified necessary modifications of watermark and requirements for watermarks surroundings thats are necessary for proper functioning of the algorithm.

Electric boiler connection in heat plant for providing ancillary services
Ditrych, Marek ; Příhoda, Martin (referee) ; Wasserbauer, Vojtěch (advisor)
The bachelor thesis deals with using the electric boiler for extension ancillary services in heating plant. The system and support services are described in the thesis, because the ancillary services regulate an energy deflection. The system and ancillary services are described in the thesis. Thanks to these services an energy deflection is regulated. The thesis describes different types of electric boilers and there functions. In the thesis is shown the possible solution of using an electric boiler in heating plant Opatovice. The cable conduction is designed for a power of electric boiler. For this reason, there is calculated the equivalent warming short-circuit current close to the electric boiler.

Project of Backup Power Source for the Heating Plant Červený mlýn
Nagy, Pavel ; Vrána, Michal (referee) ; Jára, Jaroslav (referee) ; Orságová, Jaroslava (advisor)
This thesis describes a design of backup power for heating plant Červený mlýn, Teplárny Brno, a.s. The backup power would be used in case of loss of power from the electricity grid, especially in the case of so-called "blackout". Backup power would supply only necessary systems of this heating plant, such as spinning turbines before stopping, control room power supply and lighting. Particularly designs of accumulator, flywheel and diesel generator are discussed. The main aim is to choose the optimum solution.

Biomass Heating Power Plant
Hrubý, Vojtěch ; Pospíšil, Jiří (referee) ; Fiedler, Jan (advisor)
The content of this dissertation is to utilize foundations of heat consumption in Velký Karlov and to propose and replace the main district heating plant into the heating plant which uses biomass as its fuel. With techno-economic evaluation of the annual operating central heating plant evaluate the suitability of using a steam turbine or steam engine. The proposal for a steam turbine is chosen by the preliminary calculation. There are showed suitable possibilities of working and its evaluation considered to return period.

Operational and Economical Assessment of New Turbine Installation
Čech, Jan ; Hejda, Lukáš (referee) ; Luňáček, Jiří (advisor)
This diploma thesis deals with the operational and economic assessment of the installation of new TG3 turbines in the Přerov Heating Plant. The beginning of this thesis deals with a brief theoretical introduction of this investment and describes the classical economic evaluation methods and the Monte Carlo method. Subsequently, the investment project was analyzed and inputs for the economic model were created. The economic model was then evaluated using classical methods and Monte Carlo methods, the results are then compared with each other. Based on the results of the economic evaluation, the most efficient variant of the Přerov Heating Plant technology was chosen.

Smart District Špitalka
Juchelka, Tomáš ; Hybská, Bohumila (referee) ; Sedláček, Michal (advisor)
This thesis deals with an architectural case study of the city block in the Svitava industrial zone bordered by the Svitava river in the east, Ring road in the west, Milady Horákové street in the north and Zvonařka street in the south. Špitálka Smart City is located right in the centre of this area. The thesis is modeled on the Špitálka Smart City urban study, that was the outcome of the pre-thesis seminar in the winter term 2020/21. The urban study objective was the urban renewal of the Brno teplárny (heating plant) area and its surroundings as well as a design of a new urban boulevard. To effectively use the place a residential building with commercial spaces on the groundfloor has been designed. The building consists of four sections, which share two underground storeys providing parking space and space for building services. The case study further develops only the section that is labeled A in the study. Section A offers 23 housing units and a café. The design aims at high quality housing with a view of the city replacing the former industrial zone.

Optimization of operating heating and power plant units in the PS
Bezděk, Jakub ; Radil, Lukáš (referee) ; Mastný, Petr (advisor)
This thesis deals with the structure of the electricity transmission system in Europe and their cooperation. Furthermore, it also analyzes the basic types of power plants and heating plants, then describes the optimization of operation of the electricity transmission system, the system services, support services and providing cross-border provision of electricity. Finally, work is the definition of regulatory tools and the example shows the optimal power distribution of two specific blocks for a given load.

Increasing the energy efficiency of industrial heating plant
Spišák, Lukáš ; Lisý, Martin (referee) ; Kracík, Petr (advisor)
This bachelor thesis consists of two parts. The introductory chapters are devoted to the basic description of cogeneration and trigeneration technologies, focusing on the description of cogeneration units and cooling devices. The second part of the thesis compares two specific ways of using cogeneration units and gas boilers in the CHEMOSVIT ENERGOCHEM a.s. in the town Svit. Subsequently, both variants are evaluated energetically and economically.
