Paroplynová turbína pro akumulaci energie / Steam-gas turbine for energy storageStaněk, Štěpán January 2020 (has links)
Master thesis discusses the growing need of electric energy storage and its effectivity and capacity. It describes an overview of possible technologies with their advantages and disadvantages. Greater attention is paid to the storage of energy in gas, so-called Power to Gas, which combines the electrolytic production of hydrogen from water and the Sabatier reaction to produce synthetic methane. This technology is introduced in the so-called SIT Brno cycle of Siemens Industrial Turbomachinery company. The main part of the thesis is focused on the description of this cycle and on the calculation of the steam-gas turbine (high-pressure and low pressure module). This thesis describes the methodology of turbine calculation and the composition of the steam gas mixture after combustion of methane. The carbon dioxide formed by combustion in the steam-gas mixture generator was replaced by steam. Part of the diploma thesis are drawings of cross-section of individual turbine modules.

Měření a regulace počítačem řízených solárních systémů: Vizualizace energetických systémů / Measuring and regulation of computer controlled solar systems: Vizualization of energetic systemsVlčnovská Kotlíková, Silvie January 2008 (has links)
This work is oriented on study and evaluation of performance of real operating solar system. There was made analysis of actual technological unit and there was suggested mode of measuring of nodal parameters. There was made interconnection between the head operating unit of the solar system and the web server. And there was prepared software for grafical image of time and temperature dependence and for data transfer to ready web application. It primarily talks about increase of efficiency of real technological unit through regulating of parameter that is using up of accumulated energy.

Návrh rozvoje sítě 22 kV v zadané části Brna / Design of the expansion of 22 kV distribution network in a specific part of the city of BrnoLakomý, Vojtěch January 2008 (has links)
The goal of this thesis is to design measures of the distribution network in Brno to ensure a supply of electricity to its consumers in required quantity, quality and reliability. This project will be solved in the program called PAS DAISY Off-Line v.4.00 Bizon. At first we make an analysis of the steady state of the distribution network. We check load of transformer stations 110/22 kV, overhead and cable lines if they operate in allowed limits. Then we complete or correct reserved power drains of big consumers of electricity in the model of distribution system. From the calculation of the steady state of the distribution network we will probably find out that some parts of the system are overloaded. Therefore we suggest changes for it (like switching over circuits, installation of new transformer stations and circuits), which should ensure safety and reliability of operations in the distribution system.

Optimalizace instalace kogenerační jednotky v rodinném domě / Optimizing installation of cogeneration units in family houseNovotný, Jan January 2009 (has links)
The work deals with usage of heat energy from cogeneration unit in a family house. It is focused especially on the use for family house's heating and warming of service water. Optimalization is made on existing cogeneration units. In this work we will handle with two types of cogeneration units of different capacities. From the beginning we concern in current situation and the possibilities of regulation. Further we deal with the possible ways of optimalization of winter and summer running and with the costs for these optimalizations.

Elektrická vozidla jako akumulační prvek pro elektrické sítě / Electric vehicles as energy storage element for electrical gridNovák, Martin January 2014 (has links)
This master´s thesis deals with possibilities of accumulation electric energy with the electric vehicles and their use for electric grid regulation services. In the introduction of this thesis is characterized the current world-wide state of electromobility, including the Czech Republic. Furthermore are summarized main advantages and disadvantages of the expanded involvement of the electric vehicles in the traffic. In the second part if this Master´s thesis the vehicles are divided into three main groups. The third part of the thesis describes the energy storage and generation units used in vehicles. In this part of the script are each of the energy storage parameters compared. The other chapter includes the list of current battery electric vehicles with all their important technical parameters. The fifth chapter summarizes the possibilities of the use of electric vehicles in the Vehicle-to-grid system. This chapter also discusses in detail the ancillary services of the electric grid in the Czech Republic. In the last part of this Master´s thesis there is calculated an economical potential of electric vehicles providing the primary and secondary regulation.

Rodinný dům - aktivní uzel ve Smart Grid / The family house - active node in the Smart GridBažant, Zdeněk January 2014 (has links)
This thesis deals with issues of smart houses and smart buildings. In the first part there is a research of possible systems installed in smart house. Each system is described from the perspective of its function and importance .The second part is focused on energy demands and where there is described European standard EN 15232 (Energy demand of building – influence of control automation and house management). In the practical part there was created scheme with devices which can be equipped smart houses with and their separation according to their relation to electricity. Each device is characterized by its electrical and nonelectrical parameters typical for family houses. Next part is about the proposal of prediction model of electricity consumption and generation. There are also stated quantities needed for prediction model and then method for prediction model realization.
