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.

Design for a photovoltaic plant on the roof of a house
Kattauer, Jakub ; Haluza, Miroslav (referee) ; Pěcha, Jiří (advisor)
This bachelor thesis is focused on the issues of the fotovoltaic-electricity which is situated on the rooftop of the family house. The first part of this thesis deals with a solar radiation in the region of the Czech republic, photovoltaic conversion and electric attributes of solar cells. In the following part is analysed current status of an available technology of a sollar cells. The next topic which you can deal with is a process of the manufacturing of solar cells, basic selection and partition of inverters, construction and with the manufacture of the several kinds of connection. The next chapter is about to explain how you can gain an aid of the state from the bottom to the nowadays. The last part of this thesis is dedicated to a specific proposal of the fotovoltaic factory on the rooftop, calculation of an investments that are need to be paid and enumeration of a possible financial return.

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.

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.

Energy system for energy independent object
Kaňovský, Jiří ; Pěcha, Jiří (referee) ; Mastný, Petr (advisor)
This bachelor‘s thesis deals with a design of energetic system for energetic independent family house. There are default parameters for the house defined, and an impact of house's placement in nature on thermal energy loss and on thermal energy gain due to solar radiation is described at first. There are daily diagrams of thermal energy consumption for common and heating periods derived in this thesis. An energetic system producing electric energy using photovoltaic solar panels which are placed on the house's roof is designed based on the diagrams. The thesis also introduces basic types of island energetic systems. The objective of this thesis is also a design of energetic system for heating-up (TUV) using a thermal pump, fireplace and solar collectors.

Rooftop photovoltaic system and its return of investment
Burián, Michal ; Radil, Lukáš (referee) ; Pěcha, Jiří (advisor)
The Bachelor’s Thesis is focused on a potency of using the Rooftop photovoltaic system, like the investment project. The general principle of the photovoltaic transformation and eventual utility of a sun solar radiation in Czech Republic is described in the first part of the Thesis. Furthermore there is a overview of approachable technology of the photovoltaic systems. The third part contains a review of inverters and photovoltaic systems integration. Following the complete concept of the Rooftop system and the calculation of capital expenditure for the selected property. Finally, the last part of the Thesis attend to summarize produced aggregate energy, the profit assignment due to service system. The main aim is to evaluate the Rooftop photovoltaic system and its return on the investment due to operating costs.
