Návrh blokové transformovny pro fotovoltaickou elektrárnu

Abstract

The dissertation deals with the design of a prefabricated transformer station for power output from a photovoltaic power plant. The first part presents a theoretical introduction to the topic of transformer stations, transformers and switchboards. In the next part I deal with the design of the transformer power according to the inverters of the photovoltaic power plant and the calculation of the operating costs of the transformer during 25 years. I continue with the design of switchboards and calculation of short-circuit currents to determine the short-circuit resistance. In this chapter I also designed and verified cables and flat wires for the interconnection of individual parts of the block transformer station. The design solution and earthing are described in the chapter devoted to the layout of the transformer station. At the end of the thesis I describe the project documentation. It is the main goal of my thesis. During the creation of the dissertation I based on the knowledge during my studies and experiences from my work.
