Panel Art
Váňová, Gabriela ; Magid, Václav (referee) ; Artamonov, Vasil (advisor)
The main theme of the thesis are surface mines in northern Bohemia, the Most. Grasping the subject is moving mainly in personal as well as social aspects. The basis for practical thesis served theoretical thesis. Exploring the phenomenon of a block of flats in theoretical thesis led to turn to the topic of the panel surface mines. At first glance unrelated topics, however, contains an important connection. The coal industry forms an essential part of the development of the current form of North Bohemia, a form of large prefabricated housing. Interest in the originality of the construction in the settlements led to this issue. The work consists of several authentic records and materials from surface mines in Bílina processed in painting and video.

Motorway Humpolec - Pelhřimov
Marek, Miroslav ; Seidelová, Miroslava (referee) ; Všetečka, Martin (advisor)
The subject of this final thesis is research study, which deals with new, respectively modernized route between cities Pelhřimov and Humpolec. Both of these cities are located in Pelhřimov district, Vysočina region. Route is designed in three variants: motorway, limited access road and modernization of existing road to a 2+1 configuration. Thesis is a response to new concept of motorway network, which was released by Ministry of Transportation in 2020. In this concept, there is also a plan to build new ring road, which would connect main roads in Bohemia and it would ease Prague and its surroundings from traffic.

Heating Plant Mydlovary
Víšková, Jaroslava ; Pospíšil, Jiří (referee) ; Fiedler, Jan (advisor)
The topic of this bachelor thesis is the Heating Plant Mydlovary. Especially optimization of its flow and chaining the power sources regards to the financial rationalization. The main focus is on flow of co-generation unit TEDOM Quanto D1200, which is product of Tedom s.r.o. Heating plant also consists of two warm water boilers Kotad 800 (thermal output 5,44 ) and Babcock Wanson BWN 150 with the maximum thermal output 8,0 . This heating plant is located in South Bohemia, close to town Zliv. Zliv is supplied by heat by the Heating Plant Mydlovary. Most of the houses in the city is connected in the district heating system. Whole heating plant is property of company E.ON Trend s.r.o.

Integration of Photovoltaic Power Plants in the Electricity System
Michl, Pavel ; Paar, Martin (referee) ; Mastný, Petr (advisor)
The thesis discuses an integration of photovoltaic power stations to electric network. The first part describes connecting conditions of small sources to distribution system, including administrative requirements, feasibility study, and requirements to the energy meters, measuring, control devices, switching devices and protection. The second part is aimed to describe problems of the photovoltaic system. Solar radiation generating and reducing of its intensity incident upon the earth surface are described in this part. The quantum of produced electric power depends on climatic conditions in the fixed area, seasons, etc. This work also discusses the types of photovoltaic cells and their actual efficiency. Inverters are further important components of the photovoltaic system. The parameters of the inverters have a great influence on the total actual efficiency of the photovoltaic system. Different methods of the photovoltaic panels’ connection with the inverters and their advantages and disadvantages are also mentioned. The supporting structure of the photovoltaic panels and eventually transformer are further important components of photovoltaic system. The work also analyze the methods of connection of the photovoltaic power station to distributive low voltage and medium voltage network, electric energy accumulation and possibilities of the sale of produced electric energy. The large number of the connected photovoltaic power stations has negative influences to electric network. The third part contains the design of a photovoltaic power plant with a capacity of 516,24 kWp on the scoped area in southern Bohemia. The project documentation for the location where the power plant is designed is also made. It contains the design of photovoltaic panels, the design of the inverters to get an optimal power load. This part also contains a calculation of the photovoltaic system losses and the design of transformer and the cable junction calculation of the distributive system. The feasibility study of the power plant connected to distributive system is also conducted. Its delivery rate will be connected to the distribution point Řípov (110/22 kV). The calculation results show us that this photovoltaic power plant can be linked to the distribution system. The final part of this paper contains an economic estimate of the photovoltaic power plant operating and the calculation of the return. An Economic return is influenced by the wide range of values that affect the total return rate. The calculation of an operating economy is made for several variants. The return rate in refer to contemporary redemption price for 2010 with no consideration for a bank loan is 7 years. If we consider the bank loan it would be 12 years. The penetrative reduction of the redemption price is expected for 2011. Calculation works with the decline of 30 %. It would extend the rate of return to 11 years without a bank loan or to 22 years with the bank loan. The bank loan is considered to cover 80 % of the investment.
