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

  • Introduction to electromagnetic circuits 
  • DC machine: History and state of technology, layout and function principle (engine, generator), air gap fields, armature current control, impact of commutating winding and torque generation mechanism, commutation, circuit variants, torque vs. speed characteristics of DC voltage generators (separately excited DC machine, series-wound machine)
  • Laboratory test: DC voltage generator 
  • Single-phase transformer: History and state of the technology, layout and function, vector diagram, motor and generator diagram, no-load and short circuit test, Transformer performance in service
  • Three phase transformers: Layout, converters, identification of the various vector groups (from a theoretical and experimental point of view) 
  • Laboratory test: three phase transformer
  • Electrical utilities: Function and interaction of synchrom circuits, transformers and power cable in the electrical power distribution, calculation of network voltages and currents, active and reactive power flows, personnel and machine protection
