Entry requirements

150 credits in science/engineering, including Electromagnetism, Basic Mechanics and Electrical Power Systems. 10 credits at Master's level. In addition, participation in one of the courses Wind Power: Technology and Systems, Hydroelectric Power: Technology and Systems, Wave Power: Technology and Systems, Analysis of Electric Power Systems or Power System Analysis. Proficiency in English equivalent to the Swedish upper secondary course English 6.

Learning outcomes

On 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.

Content

Magnetic and magnetically coupled circuits. Basics of electromechanical energy conversion. Design of synchronous machines. Different types of synchronous machines. Electrical and magnetic material parameters. Conventional generator windings and high voltage windings. Phasor diagram for synchronous machines, power factor, load angle and reactive power regulation. Losses, normal operation and transients in synchronous machines. Exciter, cooling system. Generator design with FEM tools. Production technology with robot control.

Instruction

Lectures, tutorials, laboratory work and project work.

Assessment

Written exam (5 credits) at the end of the course. Laborative work with oral examination (2 credits). Final report of an individual project work (3 credits).

If there are special reasons for doing so, an examiner may make an exception from the method of assessment indicated and allow a student to be assessed by another method. An example of special reasons might be a certificate regarding special pedagogical support from the disability coordinator of the university.
