Operating diagnostics of PVP
Prášil, Kryštof ; Morávek, Jan (referee) ; Mastný, Petr (advisor)
The bachelor thesis deals with the issue of photovoltaic power plants, especially their operational diagnostics and how to perform this diagnostics. The introduction of the work explains the principle of function of PV cells and describes the procedure for manufacturing these cells. Furthermore, there are mentioned methods of manufacturing individual components for assembling a PV panel. The next part lists the individual components of the PV power plant and describes their function in the entire system. At the same time, the connection methods of the PV plant are described. In the third part, we look at possible defects that affect the performance of PV systems and reduce their economic profitability. We will explain the defects of both the entire PV power plant and the individual panels and components. The following chapter is focused on explanation of individual variables related to PV power plants and what these variables are about. The fifth chapter deals with the content of the standard ČSN EN 62446. The last chapter concerns the diagnostics of the PV system itself, practical tests and evaluation of the results of these tests.

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.
