In the diploma thesis we briefly presentedthe issue of the operations of the solar power plant, operations of the island system and theelements which are necessary for its operation, as well as the description and operations of thebatteries. Furthermore, there is a description of equations for modeling of the components ofthe island system, according to which principle we also made the following calculations. Atthe end there is a discussion about the possible selections of the number of the batteries on thereal example with regards to the pretentiousness of the user, where there are the results fordifferent combinations presented graphically and descriptively.

      Master’s degree Partial discharges in insulation materials of power transformer

      The master's thesis deals with and analyzes the theoretical fundamentals for the measurement of partial discharges in pressed paperboard, which is immersed and impregnated with mineral oil and loaded with the electric field. In the master's thes; is we presented the theoretical bases of the types of partial discharges, their causes in the transformer, and gave the basical knowledge for their understanding. Further on, numerical calculation of several configurations using the Finite Element… Show more The master's thesis deals with and analyzes the theoretical fundamentals for the measurement of partial discharges in pressed paperboard, which is immersed and impregnated with mineral oil and loaded with the electric field. In the master's thes; is we presented the theoretical bases of the types of partial discharges, their causes in the transformer, and gave the basical knowledge for their understanding. Further on, numerical calculation of several configurations using the Finite Element Calculation Program (FEMM), with which we simulated the phenomena in the oil channel between two conductors with different configurations. For the experimental part, we made a test device in order to test different materials with different oil-channel width configurations while varying the strength of the electric field. Show less
