Design of a photovoltaic power plant with battery storage for a family house
Řihák, Roman ; Maule, Petr (referee) ; Vaněk, Jiří (advisor)
This bachelor work deals with the design of a photovoltaic power plant with a battery storage for household purposes. In the theoretical part are mentioned principles and explanation of the function of photovoltaic cells and accumulators. The thesis also deals with the description of photovoltaic systems and the system of accumulation of energy in accumulators. In the final part are the system and legislative conditions analyzed. In the practical part of the work is shown photovoltaic power plant design with PV*SOL software.

Single-phase DC/AC converter with output parameters 230 V / 50 Hz / 100 VA
Smolák, Martin ; Martiš, Jan (referee) ; Vorel, Pavel (advisor)
This master‘s thesis focuses on optimization of power and control circuits of an inverter, which was developed at UVEE. The principle of function and circuit implementation of a single-phase inventer, various calculations (design of an LC filter, DC link capacitor, semiconductor elements and heat sink) are described in the thesis. A design of fast overcurrent protections, oscillator and saw signal generator is included. Furthermore, a printed circuit board was designed which was optimized by thermal simulation in the Workbench Ansys. Subsequently, the printed circuit board was mounted, debugged and verification measurements were performed on it. At the end of the thesis there is a documentation for the implemented equipment.

Inverter for single-phase island network
Klčo, Michal ; Folprecht, Martin (referee) ; Procházka, Petr (advisor)
The thesis deals with a design and construction of voltage converter from 12 V DC to 230 V AC with frequency 50 Hz. Maximum output power of this device is 250 W. As a control circuit has been used IC TL494CN. The device includes undervoltage protection, which is applied if the voltage of the supply battery drops and protection against battery overcharging by solar panel. It also develops a proposal for integration the inverter into the island power system.

Use of Photovoltaic Power Plant with Batteries for Warehouse and Office Spaces
Kořenek, Jan ; Vojtek, Martin (referee) ; Mastný, Petr (advisor)
This diploma thesis deals with the photovoltaic power plant in Zlín. Power plant is used for electricity supply of office building and stock. For better self-sufficiency there is designed battery system as storage for electrical energy which the object can not consume itself. In the theoretical part there are described development of photovoltaics and components used in power plants. Further there was described the building, construction of photovoltaic power plant and eventually also a subsidy program by which the project was financially supported. Main task in the practical part was to develop scripts in Matlab for evaluation of online measured data. Next point was an energetic evaluation of power plant operation. In the end there was calculated power plant return with subsidy support and without support. These calculations were done in PV SOL software. Eventually, there was evaluated how the system works and how the power generated by the photovoltaic power plant is used. In conclusion, there is summary of the measurements and calculations.

A frequency inverter based on Texas Instruments DSP
Vašíček, Adam ; Macho, Tomáš (referee) ; Valach, Soběslav (advisor)
This bachelor's thesis discusses a one-phase frequency inverter control board design. The thesis covers basics of schematics and printed circuit board design and describes several main parts of the control software. An attention was paid to ensure electromagnetic interference susceptibility. The board extension and refinements possibilities as well as its weaknesses in both hardware and software levels are also discussed.

Photovoltaic power plants and their design
Albrecht, Daniel ; Walek, Agata (referee) ; Neuwirthová, Ludmila (advisor)
Tato bakalářská práce se zabývá fotovoltaickými elektrárnami a jejich návrhem. Významná část práce se věnuje především technologiím výroby a popisem typů a způsobu výroby jednotlivých druhů fotovoltaických článků. Práce se dále věnuje základním částem fotovoltaické elektrárny, jako jsou solární panely, baterie, regulátory, měniče, optimizery a transformátory. Součástí je také praktická část, pod níž patří kapitoly zabývající se podmínkami pro vhodné umístění elektrárny, dále faktory ovlivňujícími její budoucí energetický výnos a posléze už praktickým popisem jednotlivých komponent a součástí výstavby. Praktická část je ukončena porovnáním dvou již existujících elektráren, jenž jsou majetkem Geen Holding a.s., a kde autor práce popisuje, porovnává a hodnotí technické řešení projektů.
