This master's thesis addresses the design of auxiliary power systems for electrical substations, specifically focusing on substations operated by ČEZ Distribuce a.s. The content is oriented toward the components and operational standards utilized within this company. The theoretical part begins with a detailed analysis of the concept and equipment of transformer substations, along with definitions of individual auxiliary power systems. Subsequently, it describes the principles and structure of project documentation for energy structures. The practical part is dedicated to the technical design of the entire auxiliary power system itself. Specifically, it describes the method of implementing the power supply from the adjacent distribution network, transformation to the low-voltage level, and the subsequent design of the AC and DC systems to ensure reliable operation under all operating conditions of the substation. The thesis is supplemented by relevant drawing documentation, material specifications, and simulation models of the designed networks in Sichr and Simulink within the Matlab software environment.
