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.
