Control of proportional directional control valves
Hoferek, Martin ; Otava, Lukáš (referee) ; Veselý, Libor (advisor)
The thesis deals with design and implementation of proportional hydraulic valve, which will be integrated to hydraulic system of small hydro in Rájec - Jestřebí. This valve will be used to control one of the wicket gates of double Francis turbine. The thesis is processed for the company Mavel a.s., which is the owner of SH. The goal of this thesis is to create control of the valve according to the client's requirements, its implementation to the control system and commissioning.

Alternative solution and strength check of mechanical screens
Sommer, Matěj ; Malach, František (referee) ; Malášek, Jiří (advisor)
This master’s thesis deals with a new design of bar screens. The goal was to come up with an alternative design to already existing device by INKOS a. s. In the first part, there is a summary of various machines working in similiar conditions. The insights gained by this research influenced the design of the new device. It utilizes well proven solutions from previous projects, but some of these were reworked and a few new functions were added. Second part of the thesis describes the analytical solutions, which were used to determine the forces in the assembly during the operation of the device. Based on the results of these calculations, a strength analysis of important components was performed using the finite element method. The result of this thesis is the design and optimization of new bar screens, including engineering drawings and tools for its further development.

Small Hydropower Plant Remote Control Project
Šarman, Luděk ; Šulkovský, Lukáš (referee) ; Ondrák, Viktor (advisor)
The thesis focuses on a proposal of making maintenance and control of a small hydroelectric power station more effective. It is adjusted to the concrete situation and contains a selection of management, suitable technology, design of network infrastructure and description of an active element configuration with an appropriate proposition of financing. Then the final directions for installation and usage of a remote control system of the power station are presented as the result of this thesis.

The project of turbines for small water power plant
Dolinský, Filip ; Machů, Tomáš (referee) ; Haluza, Miloslav (advisor)
Bachelor thesis deals with usage of hydropower potential of river profile by small hydro powerplant, sollution by Archimedes and Swirl turbines is designed. In the first part, current status of hydro powerplants in Slovakia is described and obligations of the Slovak republic to the EU are analyzed. In the second part, basic division and knowledge about Screw and Swirl turbine are sumarized. The third chapter deals with design, calculations and comparison of different kinds of turbines. Most optimal sollution is analyzed, design parameters are elaborated and building cost and return of investment are calculated.

Secured control system
Kubáň, Michal ; Havlíček, Tomáš (referee) ; Pavlík, Michal (advisor)
This work deals with the design of a small hydro secured control system. The secured control system itself belongs to the Fault Tolerant Systems category. At first the requirements on small hydro control system are discussed. Then the introduction into the basics of Fault Tolerant System theory is given. The requirements on small hydro control system and basics of Fault Tolerant Systems are basis for specification of secured control system which design and construction is the main objective of this work.

Project of Small Water Power Station
Hlavica, Tomáš ; Novotný, Jan (referee) ; Matoušek, Antonín (advisor)
Hydroelectric power plants in the Czech Republic are the most important component of electricity production from renewable sources. A hydroelectric power plant in our country produces 3.9% of the total energy, which is almost half of the 8.2% of all renewable sources. Regarding the large hydroelectric power plants and those already in the Czech Republic is very likely to accrue more, because in this sphere we need to focus on smaller hydroelectric power plants, up to 10MW included. The task of this project is to design just such a small hydropower plants (SHP), which could be an interesting investment for people nearby of larger rivers. In the first part of my project is to choose a suitable area for construction of SHP. In the second part is ma task identify and propose solutions water and hydropower
