Study of connectivity for PV power station
Krejčí, Tomáš ; Bartošík, Tomáš (referee) ; Mastný, Petr (advisor)
Bachelor‘s thesis focused on studying connectivity of PV plant into the distribution system.. The first parts are processed by the conditions of connection of new resources into the distribution system with a focus on photovoltaics. Individual points are taken from the rules of the road grid, which gives the Energy Regulatory Authority. In the second part is given FVS problem. There is a brief history of photovoltaics. More details are described photovoltaic element, its principles, and different types of PV article composition PV panel. There are presented methods of operation FVS. The last section is designed to PVP via PC software.

Sports hall
Štelc, Martin ; Straka, Bohumil (referee) ; Sýkora, Karel (advisor)
This diploma thesis deals with the design expertise and supporting structures the single-roof sports hall for locality Brno. The ground plan dimensions are 42 x 72 m and ground clearance of about eight meters. Two variants are processed and selected variant is elaborated in detail. The sports hall is designed for most sports played indoors. In a static calculation are designed and assessed the main load-bearing elements such as truss glued laminated timber, wooden purlins, columns, girts and bracing. The work includes drawings.

Prefabricated concrete structure
Šimon, Jan ; Šulák, Pavel (referee) ; Bažant, Zdeněk (advisor)
The master thesis is about a design of supporting structure of prefabricated skeleton hall. The major part of a design are an internal trasverse and longitudinal frames, which contents roof reinforce concrete truss, columns, beam and ceiling joists. All the load acting to the bearing structure is transferred to the prefabricate footing made of reinforce concrete. Other parts of the bulding are not solved in this thesis. The content of the thesis consists of an assembly drawing of parts of the skeleton and the static calculation according to the actual international standards. The output of each static calculation is drawing of a shape of part and its reinforcement.

Wellness centre in Ostrava
Hruboň, Ondřej ; Rozehnal, Miroslav (referee) ; Štěpánek, Ladislav (advisor)
The Master’s Thesis deals with the design of a wellness centre and guesthouse in Ostrava. The building is in the shape of letter V with a cut corner. The wellness part consists of one and two above-ground floors and the guesthouse consists of three. The guesthouse has eleven accommodation units. Five of the units are equipped with balconies of reinforced concrete. All roof planes have a 15° slope, are non-walkable and covered by a shed roof. The supporting structure is longitudinal with cross reinforcing walls. The whole structure is made of ceramic bricks. The building does not have any basement and stands on base belts.

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.
