The project of model hydroelectric power plant
Urbánek, Jaroslav ; Macháček, Jan (referee) ; Radil, Lukáš (advisor)
Master thesis consists of the construction of a small hydroelectric power play model for laboratory use. The first step is to calculate parameters required for the creation of the 2D model Banki turbine. Next part is a proposal and selection of individual components of the model, such as generator, turbine housing, water circuit, pump and alternator mounting. The last step is to launch the model and verify, if the model of a small hydroelectric power plant achieves the required parameters.

Feasibility study of a small hydropower station within the navigation lock Přelouč II
Bolek, Marek ; Roth, Tomáš (referee) ; Dráb, Aleš (advisor)
The aim of this dissertation is to prepare a study of a small hydroelectric power plant as part of the Přelouč navigation level II. The preparation deals with one of the possible variants for the layout design of given constructions. The layout design of a weir with an adjacent lock chamber which secures navigability for the stretch of the Elbe River located between the river kilometers 949,23 and 951,20 near the city of Přelouč in the Pardubice District is also included in the study. The introduction chapter contains the assessment of the environment, which is followed by the specification of the exact placement of the constructions. In the following chapter, a particular type of the hydroelectric power plant machinery is designed based on the available hydrological information and gradient conditions. The final chapter contains the design of the constructional technological layout of an machine room in the form of a technical report and drawing documentation.

Bánki-Michell turbine set and its maximum power point control
Marčok, Samuel ; Baculák,, Tibor (referee) ; Červinka, Dalibor (advisor)
This master’s thesis focuses on maximalization of power point of Bánki-Michell turbine and asynchronous generator set in small hydroelectric powerplant with the use of frequency converter. The first chapter addresses the history, division, and construction of hydroelectric powerplants. The following two chapters describe mechanical and electrotechnical equipment that is necessary for correct design of the control. The fourth chapter describes control possibilities of asynchronous generator and Bánki-Michell turbine set. As a verification of correctness, master´s thesis involves simulation in Matlab-Simulink. Results of this simulation are addressed in the fifth chapter, where systemic behaviour in selected control approach with the maximum power point of the set is considered. The most extensive chapter is the sixth one, because it depicts detailed description of measurement in speed or torque control. Last chapter summarizes and compares measured dependences with expected systemic behaviour derived from simulation. The conclusion of this thesis raises another possibilities for improvement of water potencial usage and describes the contribution of frequency converter.

Technical design of an alternative to the small hydropower plant Ejpovice
Mitrega, Stanislav ; Jobánek, Stanislav (referee) ; Šulc, Jan (advisor)
The main purpose of this bachelor’s thesis is a new design of a small hydroelectric power plant Ejpovice with non-pressure and pressure derivation. The non-pressure part of a waterway includes design of a weir, culvert and an inlet channel. The pressure part of a waterway includes an intake object and an original tunnel. The design review includes two variants of a waterway. In the first variant water is running straight through the tunnel. The second variant is considering with a glass reinforced pipe that will be installed in the tunnel so the tunnel won’t be flooded. At first the thesis analyses all the sources for the preparation of a design and discribes an area of interest. Below the thesis presents a design of all the new building objects and technological equipments. Detailed restoration of the tunnel is also described. In conclusion of the thesis, there are calculations of a power generation and an economic analysis of both variants. The payback period of the second variant is significantly longer than the period of the first variant although an alternative design doesn’t require a comlicated restoration of the tunnel. On the basis of this fact I recommend to implement the first design.

Mechanical screens for a small hydropower plant
Lesák, Martin ; Zeizinger, Lukáš (referee) ; Škopán, Miroslav (advisor)
In the introductory part of this bachelor thesis is performed a critical search of wiper mechanisms used to clean the screens of a small hydroelectric power plant. The work also contains a substantiated concept of the proposed solution, strength calculations of important structural elements and drawing documentation of selected components.

Hydraulic analysis in the surrounding of hydro power plant
Lorenc, Václav ; Roth, Tomáš (referee) ; Duchan, David (advisor)
The diploma thesis deals with analysis of flow ratios at the hydraulic plant Klecany – Roztoky, located in the region of Střední Čechy at Vltava river (km 37,08). At this site 3D streaming of superficial water was simulated aiming to evaluate the influence of potencial construction of the new hydroelectric power plant Klecany II on existing Klecany I. Using all of the base documentation available, 3D models of current and planned conditions were created to serve as base for calculation in FLOW 3D. The first part of the thesis describes, how the planned construction of the new hydroelectric power plant Klecany II could influence the current fairway at the inlet 400 m3/s. The second part analyses shape of planned flow hydroelectric power plant Klecany II for flow Q90d, equal to 180 m3/s. All of the results are presented in intelligible charts and images.
