Feasibility study of the pumped storage power station
Kratina, Jakub ; Duchan, David (referee) ; Dráb, Aleš (advisor)
Pumped storage power stations are an integral part of all power systems. At pre-sent, they represent perhaps the only option to accumulate more surplus electricity. It is also built as a proven regulatory element of the power system. The content of this bachelor thesis is a study of feasibility of the pumped storage power stationt (PVE Podlešín) in the Vaňov area. The introduction deals with the issue of pumped srorage power station. Then the design of a technical solution for the power plant construction follows. The main part of the study is the elaboration of drawing documentation and technical reports.

Feasibility study of the pumped storage power station
Bolek, Marek ; Špano, Miroslav (referee) ; Dráb, Aleš (advisor)
The aim of this bachelor thesis is to create a study that deals with the construction of the machine cavern of the shaft-type pumped-storage power plant containing 4 machine sets of the Reverse Francis Trubine with underground penstocks and short discharge tunnels, located in the area of a quay in Vaňov in the Ústí nad Labem District. The introduction deals with the pumped-storage power plants in general. The following chapter focuses on the assessment of the locality of interest. The final part contains a proposal of a structural-technological design of the machine cavern by means of a technical report, a design of the spiral case and documentation of the structure by means of drawings.

Search on land-use planning documentation and evaluation of suitability of the location of the upper reservoir of pump storage power plant
Lebeda, Dawid ; Julínek, Tomáš (referee) ; Špano, Miroslav (advisor)
This bachelor thesis is focused on the evaluation of the suitability of the location of the upper reservoir of the pumping hydroelectric power plant and on the route of penstocks in terms of intervention in the territory. In the introductory theoretical part the pumping hydroelectric power plant is described generally, mainly in terms of its arrangement and functionality. Further, the theoretical part describes the characteristics of the area around the port town of Vaňov, which is situated in the northwest of the Czech Republic, where the power plant should be placed. In the practical part of this thesis the location of the upper reservoir and two variants of the route of the penstocks are evaluated. Using base map and land-use planning documentation an analysis and evaluation of the intervention in the current territory was carried out. Based on the evaluation, a more suitable option of the route of the penstocks is chosen and recommended.

The Conversion Efficiency of Different Kinds of Energy into Electrical Energy and the Possibility of its Accumulation
Ostruška, Jan ; Bartošík, Tomáš (referee) ; Macháček, Jan (advisor)
The thesis deals with the issues of the conversion efficiency of different kinds of energy into electric energy. Firstly, the thesis presents a brief introduction into types of energy sources and their capacity. Then, conversion efficiency of particular direct and indirect conversion is scrutinized, pointing to factors which affect conversion efficiency. The next chapter deals with the possibilities of accumulating electric energy. These are analysed as far as conversion efficiency is concerned as well and the end of the chapter concludes with comparison of these particular possibilities. Booth parts of the process – power generation and its accumulation – are connected in comprehensive scheme of energy conversions. The thesis develops on this scheme by mathematic description of its components and by designing a simulation programme, which would show the flow of energy in the scheme.

Models of the power set water turbine control
Prudek, Stanislav ; Matoušek, Radomil (referee) ; Němec, Zdeněk (advisor)
This thesis deals with modelling and simulation of the power set of pumped storage hydro plant. This power set control opening/closing the stator blades of Francis reverse turbine in Dalesice. It is a positional servomechanism where input signal is desired value of turbine opening. The goal of this work is to create computer modell of this power set in Matlab-Simulink. This modell must be comparable with properties of real power set and after modification usefull to other water power plants. Characteristics of computer modell can be verify with real measuring.

The assessment of advantages of construction of large hydroelectric power plants in the area of Cukrova bouda, district Sumperk
Knápek, Michal ; Kopřiva,, Miroslav (referee) ; Mastný, Petr (advisor)
The subject matter of the master´s thesis is, in particular, an evaluation of the advantageousness of the construction of a pumped-storage hydroelectric power station in the vicinity of Cukrová Bouda. In the master´s thesis introduction the utilisation of pumped-storage hydroelectric power stations in providing reserve power generation to the operator of a power transmission system is discussed. The thesis then focuses on a technical design solution where two alternatives are drawn up for which the nominal parameters of individual designs for a pumped-storage hydroelectric power station are specified. The following part deals with the impact of the structure and the plant’s subsequent operation on the environment. A further key part is the determination of investment and subsequent operating costs and an evaluation of the plant according to economic pointers. The final part of the master´s thesis contains a SWOT analysis and an assumed programme of works for the plant’s preparation and actual construction. The conclusion contains an overall evaluation.
