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.

Network flow models for waste management
Janošťák, František ; Mrázková, Eva (referee) ; Pavlas, Martin (advisor)
This thesis is devoted to the construction of new waste-to-energy plants in a territory where is already another fossil-fuel power station in operation. The aim is to create a mathematical model and prove that those two devices are able to cooperate effectively using same technology. Exactly assembled model under real operating have characteristics of a mixed integer nonlinear programming. The optimization software GAMS is used for its calculation. The complexity of the model, however, is at a level that solutions in bad initial conditions ends in local optima, or not found at all. This thesis is devoted to the elimination of non-linearity using binary variables and heuristic so the task was solved with acceptable time limits to guarantee an optimal solution.

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.

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.

Biomass Heating Power Plant Brno-nord
Saňka, Marek ; Skála, Zdeněk (referee) ; Fiedler, Jan (advisor)
The master’s thesis topic is the feasibility study of new biomass source construction in power heating plant Brno-North. The first part is focused on historical and current conditions and future development of heat distributions networks and sources of Brno. The power heating plant operation Brno-North is described in more detail including the current heat scheme of operation and plan for the future development. Next chapters are focused on projection of new biomass source. At first, it is defined heat output, operation range and parameters of the new source based on the data of real needs after the heating network modernization. Afterward, selected conceptual variants of the new source are discussed in more detail and for each of the variants are performed heat balance calculation and assembled heat scheme of operation. At the same time it is processed warehouse management calculation and economic analysis of the project. The final chapter evaluates the technical and economic parameters of variants and recommends the most suitable variant of the project.

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.

Heating plant modernization and environmental
Sobotka, Tomáš ; Ing.Vladimír Skula (referee) ; Fiedler, Jan (advisor)
The target of this diploma thesis is design of cogeneration unit with following requirements: • Installation of new unit instead of the old and used up one. • Electric energy supply within Supportive service – fast starts • Greening (replacement of coal with natural gas) At the beginning I deal with the current state of old unit. In the next part there is the design of new technological unit, which consists of design of boilers, gas engines, steam turbines. Final phase of the thesis includes economical analysis focused on setting of financial return.

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.

Operation check of dredge pump
Pleban, Jakub ; Fiedler, Jan (referee) ; Skála, Zdeněk (advisor)
The aim of this thesis is to consider the operation of dredge pump and design new technology of slag removal including return on investment calculation. The operation optimization itself was preceded by analysis of present technology, data collection, calculation of pressure losses and pinpointing the causes of their origin. Subsequently, the measures to elimination of losses were deduced and these measures were implemented into optimization of dredge pump operation itself. The return on investment into the new technology of slag removal is calculated in the last chapter, considering its feasibility in the heating plant.
