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.

Renewable energy sources in the region of the North Moravia
Mazák, Tomáš ; Hrnčířová, Michaela (referee) ; Pospíšil, Jiří (advisor)
The content of this work is to search an overview of basic types of renewable resources in the region of the north Moravia, respectively in the Olomouc region. In this work, are clearly described the main sources that are used in our country, especially the potential of photovoltaic systems, wind energy, water energy and biomass. For each type of renewable source is depicted a principle and the possibility to use just in the region of the north Moravia. In addition, specific applications are described in the Olomouc region, using these energy potentials.

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 assessment of connectivity 138 MW combined heat and power plant in Prostějov
Vacek, Tomáš ; Opat, Jaroslav (referee) ; Bátora, Branislav (advisor)
The goal of this project is to test the possibility to connect the Cogenerational generation of power 138 MW (still in the development stage) to the control room 110 kV in Prostejov production. This merge would product the electrical energy as well as the heat energy for all local area. In this dissertation we will be considering the solution of the steady state (stationary state) of system with the voltage level of 110kV, as well as the influence of the generation of power on this system, there by the suggesting a connection. The Congenerational production indicates higher effectiveness in the transformation of energy during primary production process due to the production of heat energy as well as the electrical energy from the primary power sources. In our country, as well as around the world, commonly used fuels are fossil fuels- coal, crude oil, and gas. As the demand for energy grows, those supplies are slowly running out. Not to mention that those fuels have a negative environmental impact. They are a source of carbon, which causes damage to the atmosphere and leads to global warming. Power plants which do not produce carbon are much safer for the environment, and much more productive. However, the residue of this energy is challenging to dispose of. Nuclear energy has common attributes with renewing the sources of energies that are extremely friendly to our environment. Nuclear power plants also produce enough energy and with the usage of Fourth generation reactors, they will be able to recycle the nuclear fuels. Today, more importance is put on renewing sources which are more gentle for the environment. In the near future, CEZ Company, the largest producer of electric energy is planning to use water energy. Water energy comes from water plants or dams. Other ecological forms of energy include geothermal and solar energies. These two types of energy are not as applicable for our geographical position. Geothermal energy is commonly used on islands where there is an abundance of natural hot springs. The most discussed source of energy is bioenergy. It uses natural wood sources, recycled wood products, and applies bioenergy as a main source for thermal power plants.

Adaptation of historical technical facility on the small hydroelectric power
Čermáková, Klára ; Sluše, Jan (referee) ; Hudec, Martin (advisor)
Small hydroelectric power stations are the topic of this bachelor thesis which can be divided into three parts. The first one describes a history of utilising water energy, elementary types of hydropower projects, and classification of hydroelectric power stations. The second part is focused on small hydroelectric power stations. Finally the acquired knowledge is used in the last part describing the proposal of an adaptation of the water mill in Lomy to a small hydroelectric power station.

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.

Usage hydropower potential on river Tichá Orlice
Rybka, Michal ; Procházka, Zdeněk (referee) ; Matoušek, Antonín (advisor)
This bachelor thesis solves proposal of small hydro power station. The first part deals with energy resources, especially water energy and energy use in the Czech Republic. River Ticha Orlice is characterized in other part, comparing of five weirs is necessary part. Next chapter is proposal of small hydro power station particular its electrical parts, including the connection to the distribution system. Finally, investment evaluation of proposed small hydro power station is mentioned.
