Small hydropower plants in the Czech Republic
Bursa, Ondřej ; Preisler, Lukáš (referee) ; Sitek, Tomáš (advisor)
There are more than 1,600 hydroelectric power plants in the Czech Republic. Almost all of them belong to the category of small hydropower plants. This thesis summarizes the current state of small hydropower plants in the Czech Republic and the possibilities of future development. Furthermore, the work contains a description of the situation of the Svratka river, gathers information about the already installed power plants and outlines the possibilities of further progress.

Conceptual design of a hydroelectric plant on the Liwagu River in Malaysia
Hamsová, Adéla ; Jobánek, Stanislav (referee) ; Šulc, Jan (advisor)
The bachelor thesis deals with the conceptual design of a small hydropower plant on the Liwagu River in Sabah Province, Malaysia. The background and site survey was provided by Stream Ltd. The work included the design of the intake structure, intake pipeline, engine house and its process section. A suitable type of machine was selected for the hydropower plant. At the end of the work, an economic analysis of the project was prepared. In terms of payback, the project was evaluated as beneficial. The bachelor thesis includes a calculation part, a drawing part and a photo documentation of the designed site.

A study of a small hydropower plant
Bartůněk, Tomáš ; Špano, Miroslav (referee) ; Dráb, Aleš (advisor)
The aim of this bachelor thesis is the design of a small hydroelectric power plant on the Jihlava River at river km 136.741. The purpose of the construction is to use the hydroelectric potential of the stream for power generation. The subject is also the use of PROTUR turbines at the weir construction. The study includes a technical report, hydraulic and hydropower calculations, drawings and photo documentation.

Hydraulic solution of the swirl turbine for locality of Rosenauer mill
Pavlíček, Tomáš ; Veselý, Jindřich (referee) ; Haluza, Miloslav (advisor)
This thesis focuses on the design of a swirl turbine for the site of Rosenauer Mill, where the gross hydraulic head HB is 1 m and the flow rate is Q is 1.6 m3/s. The beginning of the work is dedicated to microturbines and explains why a swirl turbine is suitable for this location. The procedure applied for developing the hydraulically active surfaces of the turbine is then presented. Firstly the design of the blades is based on analytical formulas, which are further refined using the CFX Ansys program. The turbine is closely affected by the inlet and draft tube, therefore their design is also included in this thesis. The hydraulic calculations yield the resulting parameters and characteristics of the designed turbine, calculated from the entire assembly using CFD computations. The final section of the work is devoted to the design of main structural components such as the gear, shaft, and bearings. The hydraulic design developed in this thesis serves as the basis for implementing the swirl turbine and constructing a small hydraulic power plant at the Rosenauer Mill.

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.

Spiral case design for fountain turbine Katovice.
Čípa, Jiří ; Veselý, Jindřich (referee) ; Haluza, Miloslav (advisor)
The diploma thesis should identify inconsistencies of the small hydraulic power plant Katovice. The fountain water turbine is now running in slower delivery because the original Francis high speed turbine achieved much smaller flow than a Kaplan type turbine. The aim of the thesis is a project of a spiral case and a distributor for the Kaplan turbine, which should work in higher flow and should be run in its optimum. This project will serve as a base for construction of distributor and spiral case for the small hydraulic power plant Katovice.

Design of the gated weir
Skřička, Jakub ; Uhmannová, Hana (referee) ; Julínek, Tomáš (advisor)
The Bachelor Thesis deals with the study of the existing uncontrolled weir on the river Svitava in district Brno-Obřany. The first part of the Thesis contains a theoretical part about theme of weirs. In the next part Thesis describes the current state of the area of interest, including the riverbed of Svitavy with neighboring objects. After that the Thesis describes the design of the reconstruction, including the selection of suitable movable construction and procedure of hydrotechnical calculations. In conclusion, a calculation of the stability of the design was described.
