Electrical installation of multifunctional house using intelligent control
Kroutil, Roman ; Bátora, Branislav (referee) ; Mastný, Petr (advisor)
The aim of the thesis is the theoretical clarification of the issue of intelligent electrical installations, electro project documentation creation and a specific development project, smart wiring. The work consists of three parts. In the first part the reader is becoming familiar with the power distribution problems and subsequently in details with the issue of intelligent electrical installations. This thesis describes the development, standards and use of the intelligent systems. There is also a description of the various manufacturers and their systems, which are widespread in the Czech Republic, followed by comparing them according to selected criteria and finally the advantages and disadvantages are compared to the traditional smart wiring. Another part deals with the principles and methods of making electrical projects. There are all part of the project documentation procedure for their creation, the principles to be observed, and the most important and most relevant standards, laws and regulations relating to the right wiring are given. The last part is completely processed wiring project using intelligent control. The project consists of all the elements needed for building management, which are drawings of floor plans of all floors of the building, all switchboards schemes, scheme and system power distribution, inventory of material used and the technical report.

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.
