Study of the small water power plant which is situated in the middle and lower reach of river Morava
Dočkal, Jiří ; Malý, Jiří (referee) ; Matoušek, Antonín (advisor)
The present thesis deals with the description of the current state on the course of Morava river from small hydro Kromeriz after a small water plant Hodonin. Subsequently, I deal with the description of search of weir plants and weirs for the construction of small hydropower (especially their heads, structures and, where appropriate, possible adaptation). Then I deal with completion new hydroelectric plants on this founded weir plants and weirs which are in section between the small hydroelectric power Kromeriz and Lanžhot city on the Czech Republic side (Brodské on the Slovak Republic side). In this work is mainly focus on the calculation of installed performance in individual locations (and also the calculation of achievable performance in these locations), machinery design (for the use of selected sets from Hydrohrom company) and the way the configuration of the power switch. If it is in those places, řeším even more possibilities of this construction is splavnění view of the river, especially in the field of Hodonin - Lanžhot. In addition, deals with the design of line side cubicle of each switch to local distribution networks (draft routes). In the last phase deals with the size of the production in each generation, calculations of costs of constructing these plants, approximate calculation of the production (of the flows of 2007) and time of return on your investment in the construction.

High Speed Turbine with Non-Uniform Cascade
Stareček, Jakub ; Drábková, Sylva (referee) ; Veselý, Jindřich (referee) ; Haluza, Miloslav (advisor)
This doctoral thesis is focused on hydraulic design of axial turbine by CFD and FEM analyses. The results are runners with nonuniform cascades. Nonuniform runners consist of blades with different axial positions, blades with different pitch angles in runner or indifferent blades. Each runner is designed with respect to 3D printing by FDM or SLS technology and hydraulic measuring. The analyses of the excitation frequencies, modal analysis, shape of the turbine operating range, maximal efficiency, output parameters and cavitation properties are emphasized.

The turbine regulation of the small hydro-powerplants
Horký, Jiljí ; Dobrovolný, Martin (referee) ; Stareček, Jakub (advisor)
This bachelor thesis deals with the regulation of water turbines in small-hydro power plants. The first chapter presents the basic theory of this issue. In the next following two chapters, the characteristics of individual types of turbines, their construction and construction of control mechanisms are introduced. With the help of velocity triangles is shown, how the flow conditions are changing during the work of control mechanisms and what influence the control has on the hydraulic machine.

Small hydro power plant restoration project
Morávek, Jan ; Bartošík, Tomáš (referee) ; Radil, Lukáš (advisor)
This thesis summarizes the basic theoretical knowledge concerning of small hydro power plants. It describes the current state of small hydro power plant, analyzes the current solution and its drawbacks. The thesis further decribes options of possible improvement using suitable expansion. The last part of the work deals with an estimated production of electricity after the reconstruction, the approximate investment costs and the estimated time of the investments return.
