Design Of Back To Back Converter For Small Hydro Power Plant
Rubes, Ondrej
Renewable energy sources are important in recent years. Small hydro power plants are one of them which does not devastates the country, and which has relatively stable operation. However, in summer time with low river flow, they operate with low power and they have low efficiency. This paper demonstrates method to decrease the losses by back to back converter. Design of the converter is described, and fabricated part of the converter is depicted.

Hydraulic powered screens for small hydropower plant
Snášelová, Dana ; Stodolák, Michal (referee) ; Škopán, Miroslav (advisor)
This diploma thesis deals with the design of hydraulic cleaning machine of fine screens located in the supply channel of small hydropower plant. The part of this thesis is also the design of hydraulic circuit and strength analysis using finite element method. The thesis also deals with the optimal debris removal. The thesis is attached by drawing documentation of selected parts of the mechanism.

Possibilities of using small hydroelectric power plant in the wastewater treatment plant
Krúpa, Lukáš ; Haluza, Miroslav (referee) ; Pěcha, Jiří (advisor)
This bachelor’s thesis focuses on the possibilities of using small hydroelectric power plant in wastewater treatment plant. The first part is theoretical and describes the theory of wastewater treatment plants, small hydro power plants, turbines and generators. The seconds part focus is to describe the design of small hydro power plant. It begins with description of location then continues with calculation of Banki turbine and ends with generator selection. The last part deals with an economic evaluation, which includes estimating of the investment costs, the price of saved electricity and determining the estimated return on investment. In conclusion the thesis compares the ways of using the produced electricity.

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.

Hydraulically driven screens
Forman, Ladislav ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
The main objective of this work is the calculation of selected parts of hydraulically driven screens such as cleaning equipment before entering the small hydro power plants. The thesis is divided into two parts. The first part focuses mainly on the calculation of hydraulic mechanism for cleaning screens. The second part contains a drawing of the general assembly hydraulically driven screens and sub-assemblies.

Visualisation of hydraulic structures
Urbanec, Luděk ; Duchan, David (referee) ; Dráb, Aleš (advisor)
The aim is to implement the process for creating realistic visuals (including animations) for a small hydroelectric power plant Litomerice. This thesis is the creation of spatial models based on existing drawings. Using these models will be developed with an emphasis on rendering realistic scenes created. An important part of the work output will also be focused primarily on the animation feature demonstrations of technological equipment, handling and maintenance work on the water. A key outcome will be the documentation process of spatial models, realistic rendering and animation.
