Electrical installation of family house - project documentation
Šerý, Petr ; Vrána, Michal (referee) ; Mastný, Petr (advisor)
This bachelor thesis is called Family house electro installation – project documentation. The main aim of this thesis is to introduce readers into the design of the installation family house. In the first part was explained themes of engineering, legislative rules and external influences. The next topics were instalation and description of electric way from distribution site to a plug. The next aim was to get familiar implementation of house distribution system. End of thesis discussed about project documentation – technical report and drawings.

Project of Backup Power Source for the Heating Plant Červený mlýn
Nagy, Pavel ; Vrána, Michal (referee) ; Jára, Jaroslav (referee) ; Orságová, Jaroslava (advisor)
This thesis describes a design of backup power for heating plant Červený mlýn, Teplárny Brno, a.s. The backup power would be used in case of loss of power from the electricity grid, especially in the case of so-called "blackout". Backup power would supply only necessary systems of this heating plant, such as spinning turbines before stopping, control room power supply and lighting. Particularly designs of accumulator, flywheel and diesel generator are discussed. The main aim is to choose the optimum solution.

Operational Diagnostics of PV plant -T14 - Operation Optimizing
Kroutil, Roman ; Vrána, Michal (referee) ; Vavera, Miroslav (referee) ; Mastný, Petr (advisor)
The aim of the Thesis is theoretical clarification of the issues of photovoltaic power plants, their diagnostics, inspection and performance measurement, including negative impacts on their operation and subsequent application of theoretical knowledge during practical inspection and diagnostics of PV power plants. In its introductory part, the Thesis deals with design, manufacturing and development of PV cells and panels and describes other necessary elements and components, including their use in individual types of photovoltaic systems. Another part describes electric parameters of PV cells and panels, especially the parameters that can be found out by measurement of V-A characteristics and also the parameters affecting the shape of the V-A characteristics. The third part is focused on failures of photovoltaic systems, which include various defects of photovoltaic cells and panels, it also provides for adverse factors affecting operation of the entire system, associated not only with weather influences but also with the actual design of the photovoltaic system. The fourth part deals with possibilities of increasing the cost-effectiveness of electricity generation by PV power plants on the basis of practical experience of their operators. The subsequent part determines, on the basis of technical standards, procedures for PV power plant inspections, the procedures for measurement and diagnostics of PV power plants and also other prerequisites connected with inspections and measurements. This part includes also a description of requirements for measuring devices, most frequent measurement errors, adverse impacts affecting measurements and methods of assessment of the data measured. The last part of the Thesis is practical. At first it deals with verification of the impact of defects of PV modules on the shape of their V-A characteristics, then with execution of inspections and diagnostics of a particular PV power plant, evaluation of the data identified and measured, as well as with a proposal of optimisation measures to increase cost-efficiency of the operation of that particular PV power plant.

Information System Assessment and Proposal for ICT Modification
Vrána, Michal ; Rašková, Kateřina (referee) ; Koch, Miloš (advisor)
The information system currently holds an essential role. Thus, it is necessary to keep up to date and fully compliant business needs. This thesis focuses on the comprehensive analysis of a selected information system. Its findings will contribute to finding appropriate solutions for improvement. It also aims to optimize the information system to perfectly cover the demands that are placed upon it.

Verification of Mathematical Model for Small Power Sources
Vrána, M.
This paper describes a method of verifying the mathematical model of the power supply. Simple equations describing the specific energy source. As an example photovoltaic panel was chosen. Simultaneously, there are described equation for calculating the solar radiation incident on the optionally oriented surface. These equations are used to model and convert the radiation which is recorded by meteorological stations. Reference panel and load are used for model validation. The goal of this paper is to describe a model of energy sources and its validation.
