Learning outcomes:
After successfully completing this module, students will have acquired a deeper understanding of the dynamics of the equipment used in power supply networks. They will have a solid understanding of the structure and significance of equivalent networks and how they are used to model the dynamic behaviour of grid equipment. They will also have learned about computing the dynamics of electric power supply networks and will have gained a basic understanding of the mathematical and physical computational methods involved. Other areas covered in more detail in this course are the calculation of short-circuit currents according to the VDE 0102 standard and the interpretation of the results of these calculations. Students will also learn the basics of applying CAE tools to modelling dynamic processes in power supply networks and will be able to perform such calculations themselves.
Furthermore, students will acquire a fundamental understanding of the structure of switchgear assemblies and of the fuses, switches and circuit breakers used in the electric power supply sector. They will be in a position to select the requisite fuses, switches or circuit breakers for a specific application and will know how to use the chosen piece of equipment while taking into account specific technical constraints.
