Study of turbine with side channel runner
Jandourek, Pavel ; Haluza, Miloslav (referee) ; Pochylý, František (advisor)
This thesis deals with proposal of constructional solving turbine with side channel. Basis for the design is lossy characteristics of the valve. The intention is to replace hydraulic closures by turbine with side channel runner. Hydraulic losses in the flow restriction in turn replaced by the electricity generation in the comparable characteristics of valve and turbine.

Draft tube role in hydraulic turbine performance
Havlát, Pavel ; Himr, Daniel (referee) ; Rudolf, Pavel (advisor)
This bachelor’s thesis deals with the problems of draft tube. It contains basic description of draft tubes, their division and possibilities of their utilizations. Further, this thesis focuses on description of draft tubes, their efficiency, losses and ways to eliminate these losses. One part of this work also mentions basic relationships required for computing length of draft tube, velocity of the fluid in the draft tube and others.

Water turbines and them use
Machát, Pavel ; Sloupenský, Zdeněk (referee) ; Himr, Daniel (advisor)
This bachelor´s thesis deals with the problems of water turbines. It contains basic division of water turbines, description of their oparations and possibilities of their utilizations. Further this thesis focuses on description of the three most used turbines i.e. Francis´s, Kaplan´s and Pelton´s turbines. As one component of this work there are also mentioned essential relations required for selection of proper type of turbine in dependency on speed, slope and flow rate.

The projekt of the small water power station
Steidl, Adam ; Pěcha, Jiří (referee) ; Matoušek, Antonín (advisor)
This Bachelor thesis deals with a concept of a small hydro power plant. The first part is focused on hydro power potential of the Czech Republic, the general theory of small hydro power plants and their division. The following part discusses about the selection of suitable localities for construction of small hydro power plant and the decision of choosing the best of them. The selected locality is described and evaluated. Subsequently, the thesis deals with the theory of water management and hydro power solution of small hydro power plant. Futher the concept of a small hydro power plant is outlined. This concept consists of a theoretical solution of the hydraulic circuit and more detailed it focuses on the selection of appropriate sets. Then the thesis characterizes the concept of electric part of the small hydro power plant and its connection to the Distribution network. This part of thesis is aimed to compensation of reaktive powers, a concept of cabel for pulling of power of power plant, protections and automatization of the small hydro power plant. Finally, the economic evaluation of the investiment is done.

Segner wheel
Jahn, Jan ; Hudec, Martin (referee) ; Fic, Miloslav (advisor)
This bachelor thesis focuses on description of water turbine called the Segner wheel, which is considered as a precursor of modern water turbines. Segner’s contribution is to demonstrate an opportunity of dynamic force exerted by fluid jet. There is some historical information about his life and additional adaptations of the original invention. Wheel function analysis is based on laws of hydrostatics and hydrodynamics. The Segner wheel model is a part of this thesis. Last chapter discuses applications of the Segner wheel up to the present day.

A study of small water power resource
Demovič, Petr ; Pěcha, Jiří (referee) ; Matoušek, Antonín (advisor)
This Bachelor thesis deals with a concept of a small hydro power plant. The first part is focused on hydro power potential of the Czech Republic, the general theory of small hydropower plants and their division. The following part discusses about the selection of suitable localities for construction of small hydro power plant and the decision of choosing the best of them. The selected locality is described and evaluated. Subsequently, the thesis deals with the theory of water management and hydro power solution of small hydro power plant. As the next step was to design the most suitable turbine. Then the thesis characterizes the concept of electric part of the small hydro power plant and its connection to the distribution network. This part is focused on the design of the most suitable generator, compensation of reaktive powers, a concept of cabel for pulling of power of power plant a protections. The last part is about economic evaluation of the entire investment and environmental evaluation.

Control systems of Kaplan Turbine
Pavelka, František ; Kárník, Jan (referee) ; Fic, Miloslav (advisor)
The main objective of this bachelor´s thesis is to list briefly the most common types of water turbines and explain the construction and especially regulation of Kaplan water turbine. Second task is to describe individually both regulatory mechanisms and movements in the machine during the regulation by distributor and by blades of runner wheel. The next intention is to describe the influence of regulation on the efficiency curve and further briefly explain and compare the modern control systems of turbine regulation with the old way using the centrifugal regulator.
