Entry requirements

180 credits in science/engineering, of which 20 credits at Master's level, incl. Electromagnetism II, Basic mechanics and Electrical power systems. Attendance of a course within power engineering at Master's level, for example Wind power – technology and systems or Hydroelectric power – technology and systems.

Learning outcomes

Upon completion of the course the student should be able to:

• dimension a synchronous machine with computer aided tools,
• suggest changes in the magnetic, electrical, mechanical or thermal design of a generator and explain the consequences thereof,
• describe the coupling between the magnetic, electrical, mechanical and thermal design of a generator,
• derive the generator formula from Maxwell's equations,
• optimise the design of the magnetic circuit in a generator,
• calculate the power factor and load angle from phasor diagram,
• describe limitations with different materials from electrical and magnetic material parameters,
• suggest design changes to minimise losses.
