This paper describes the configuration and protection settings check of solar power plant in the simulation interface DIgSILENT Power Factory. Described is what is needed to keep the system functioning normally and in order to be protected in the event of a short circuit. The emphasis is on the simulation of real-life situations and events that occur, rather than on the detailed descriptions of parts of the network. In modeling of short circuit, careful attention to even the smallest change during its duration is spotted. The work is divided into several sections. The introduction briefly describes the name of the chosen theme, the simulation tool the data source and the name of solar power plant. The second section contains basic information about the plant and its description. The third section describes the single line diagram and its every element separately The fourth unit contains what is most important in this work, simulations of each event and their oscillograms from which are conclusions presented about the behavior of voltage and current on the occurrence of a short circuit. Finally, comments on the whole thesis are given.
