Abstract:
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.

Abstract:
This theses reports on facts about pumped storage power plants. The first part of the theses introduces us to the importace of hydropower, consists of a description of historical development of pumping sets, and also defines limitations for its potential suitable localization. The research is processed via ArcGIS software and it´s methodologically divided into three phases. The first phase is searching for the minimum suitable terrain gradient on the whole Czech landscape and it defines local insterests for the next phase of research. The second phase is based on limited factors and assesses the chosen location of interest. The final phase provides detail on the most potentially suitable destinations with specific locations of pumped storage power plants. The study resulted in map outputs of final destinations and locations of interest across the Czech landscape. The distinction of source data and the importace of classification of enviromental factors are included in the discussion.

Abstract:
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.

Abstract:
Theme of this master's thesis Comparison of thermal cycle efficiency is aimed on the calculation of thermal schemes of reheating and without reheating for various performances. The calculation is performed using specialized literature. The introduction describes the fundamental thermal cycle used in power plants and Rankine - Clausius cycle. After the initial familiarization with the parameters of Rankine - Clausius cycle follow a section with technical solutions to improve thermal efficiency of Rankine - Clausius thermal cycle. The aim of this work is to identify and compare the thermal efficiency of the thermal cycle with reheating, without reheating and compare them with each other. At the conclusion of this work is shown comparison between two low-pressure regeneration systems.
