Fundamentals of Power Engineering

Learning goals

The module provides the understanding of the basic aspects of electromagnetic power system operation and control, under both steady-state and rotating conditions and their influence on the operating conditions. It further gives an understanding of the appropriate application of power electronic devices and measuring equipment, and basic knowledge of the functioning conditions, operating behaviour and interaction of energy supply equipment. The students will also acquire skills in teamwork and presentation techniques.

Course contents
