After successfully completing this course, students will be able to apply modal transformations to calculate symmetric and asymmetric network states in forward and backward transformations. They will be able to calculate voltages and currents in the symmetrical and asymmetrical normal and short-circuit operation of electrical power supply networks with the aid of symmetrical components. Students will be able to create the equivalent circuit diagram of an electrical power supply network in symmetric components and calculate short-circuit currents and node voltages. They will be able to select equivalent circuits for equipment on a case-by-case basis and parameterize them with nameplate data. They will able to calculate wire nameplate data from the wires" geometrical and electrical parameters. Students will be able to analyze the design and structure of switchgear and assess the significance and functionality of the components used in it.
1. Modal transformations: diagonal transformations, symmetric components, 012- and hab-system, physical interpretation 2. Power lines: Structure, transmission tower shapes, overhead line cables, mean geometric distance, ground wire reduction factor, inductors and capacities (symmetrical components), homogeneous transmission line, characteristic impedance and natural power, equivalent circuit diagrams 3. Transformers: Three-winding transformer, zero phase-sequence system 4. Asymmetrical mains operation: Symmetrical and asymmetrical errors, application of symmetrical components, transverse errors, longitudinal errors 5. Switches and switchgear: switch types, switch requirements, switching off in three-phase systems, construction and structure of switchgear, switching in switchgear, current and voltage transformers
