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.

The Design of a Rules for the Hydropower Control of a Dam Reservoir
Bednář, Martin ; Kříž, Tomáš (referee) ; Menšík, Pavel (advisor)
The aim of the diploma thesis is to create an algorithm by which it will be possible to devise management rules. These management rules will be able to advise a more efficient use of the hydroenergetic potential of reservoirs with run-of-river small hydro. The actual algorithm will be created with a view to maximizing the profit from the operation of the hydropower plant and using the time course of electricity prices on the market. The rules designed by algorithm will be tested in a simplified way in selected period using simulation model.

The computation of draft tobe of the turbine for giving parameters
Žák, František ; Veselý, Jindřich (referee) ; Haluza, Miloslav (advisor)
This diploma thesis describes design of a new shape of the draft tube for small hydro Katovice with maintaining built dimension. First part of this thesis is devoted to the formulation of the problem, description of basic function of the draft tube, its efficiency and other formulas. In the second part of this thesis the analysis is made for original design supported by CFD calculation. Furthermore a new design of the draft tube is made with comparison of original draft tube.

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.
