Photovoltaic system project for the Holešov commercial building
Pospíšek, Timotej ; Vrtal, Matěj (referee) ; Mastný, Petr (advisor)
This bachelor’s thesis focuses on the design and implementation of a photovoltaic system (PVS) for a commercial building in Holešov. The main objective was to develop a comprehensive project for a category A2 photovoltaic power plant that meets the requirements of the distribution network operator and maximizes the use of energy produced on-site. The work is divided into three main parts: familiarization with the rules for connecting and operating sources with inverters according to PPDS and RfG, design of the photovoltaic system including storage device, and preparation of project documentation for building permits. The results indicate that the proposed system is economically advantageous and contributes to environmentally clean energy supply. The economic analysis of the project, which includes available subsidies, confirms an investment return within 8 years.
Creating learning support materials for design in electrical engineering using the EPLAN software tool
Benešl, Miloslav ; Vrtal, Matěj (referee) ; Bátora, Branislav (advisor)
The bachelor thesis deals with the creation of materials to support the teaching of the XPC-EPL course. The thesis starts by describing and comparing modern software for creating project documentation in electrical engineering. The next part of the thesis introduces the issue of normative requirements for project documentation. The second half of the thesis introduces the design program EPLAN and the operation of the student version of EPLAN Education. Then it describes the instructions for creating a training project of an industrial furnace with a cart.
Modernization of LV switchboards in meshed network in Brno
Kalina, Šimon ; Nedoma, Jakub (referee) ; Vrtal, Matěj (advisor)
The purpose of this bachelor thesis is to conduct a research on the topic of LV grid, its application and specifics of its operation and design in the first part. This part also describes the indicators of the quality of power supply, their impact on the distributor and the influence of the grid network on their form. In the practical part, for a specific investment action consisting in the renewal of LV switchboards in the grid node stations in Brno, a technical report is prepared, which will serve as a basis for the implementation of the renewal itself. Furthermore, the current development of the switchboards is evaluated and a solution is proposed for the reconstruction of the stations, including atypical ones.
Design of photovoltaic power plant in area Špitálka Brno
Jedlička, Dominik ; Vrtal, Matěj (referee) ; Bohůn, Vojtěch (referee) ; Morávek, Jan (advisor)
The aim of this work is to design a photovoltaic power plant on the roof of the area Špitálka part of company Teplárny Brno. The theoretical part discusses the types of photovoltaic cells, the possibilities of recycling photovoltaic panels, components of photovoltaic systems and the design of the power plant itself. The practical part is followed by the design of the power plant with the use of information gathered in the theoretical part.
