Reneweblw energy source at Slovakia
Szegedi, Peter ; Borbély, Richard (referee) ; Fiedler, Jan (advisor)
The bachelor thesis is divided into five main issues. The first issue is dealing with history of exploitation of water as a power supply in Slovakia and is describing current situation of exploitation of watercourses. The next part of the thesis is describing a present condition of power industry in Slovakia, its future perspective and a possibility of deriving benefit from the most perspective renewable resources of energy. The essential issue handles with water power stations ant its description. The last capture is focused on small hydroelectric power stations and technic – economical evaluation of three concrete SHPS. The conclusion is attending to short overview of information obtained by writing the bachelor thesis and to author’s own estimation of development of renewable energy sources situation in Slovakia.

The storage water plants problem appreciation
Archalous, Jakub ; Himr, Daniel (referee) ; Sloupenský, Zdeněk (advisor)
This bachelor’s thesis deals with the use of hydropower. It gives an overview of hydroelectric plants and describes mechanisms that convert water energy into electric energy. The most attention is paid to the principle and operation of pumped storage power plants and the machinery used there. Also the efficiency of the pumping cycle at Dlouhe Strane power plant is calculated.

Adaptation of the Watermill
Pavlík, Jan ; Hudec, Martin (referee) ; Klas, Roman (advisor)
The bachelor´s thesis is composed of two parts. In the first part, there is a generally discourse about small water power plants, their structural design, mechanical equipment and economical efficiency and its function is to create the basic conception of the waterwork. The second one deals concretely with the small water power plant in Crhov, that was rebuilt from the original mill by Mr. Petr König in 1990s.

Contactless Measuring Method of Blade Vibration during Increasing Turbine Operational Speed
Procházka, Pavel ; Vaněk, František ; Cibulka, Jan ; Bula, Vítězslav
A novel method for contactless measurements of turbine blade vibration during increasing or decreasing operational speed is presented. The method is based on the evaluation the time differences of blade tips passing along contactless sensors placed on the stator, and the substitution data correction using a numerical model. The method has been verified both numerically and experimentally. For the experimental research on the model bladed wheel of the Institute of Thermomechanics and subsequent applications in operating conditions, two new types of sensors functioning on the magnetoresistive and induction principle have been developed.
