STE6225 Electrical Machines and Power Electronics 2 - 5 stp

The course will describe the design, operation, and control of electrical energy converters. Electric transportation, renewable energy and energy storage will be used as application of power converters throughout the course. The emphasis is on control algorithms and dynamic operating characteristics.A design project will be completed in groups. Laboratory and experiments is a central and integrated part of the course, including the project work.

Power conversion:

• Converter circuit topologies
• Modulation strategies
• Dynamic models
• Active and reactive power control
• Predictive control algorithms

Motor drives:

• Mechanical and electrical modelling.
• Dynamic operating characteristics.
• Advanced control strategies of AC drives based on vector control and direct torque control.

After passing this course, the student shall have the following learning outcome:

Knowledge:

• The candidate will have an insight in rotating electrical machines and their application.
• The candidate can explain the functionality of power converters for motor drives and grid connected applications.
• The candidate can explain the concept of predictive control methods.
• The candidate knows how to use simulation software such as PSPICE and MATLAB to support all phases from specification to design of power electronic systems.
• The candidate has knowledge on using scientific instruments and rapid prototyping systems in developing control algorithms.

Skills:

• The candidate are able to create mathematical load models of mechanical and electric systems
• The candidate can create simulation models of power electronic converters, control algorithms and mechanical systems
• The candidate can apply advanced control algorithms and strategies to control motor drives and grid connected converters in a laboratory environment.
• The candidate can design and select components for power electronic systems based on mechanical and electric system requirement specifications.

General competence:

• The candidate will gain competence in future design activity in the field of industrial electronics.
• The candidate will have an overview of documentation standards and training in technical writing.

Mandatory tasks Completed the required HSL courses within laboratory work and safety is required be approved before gaining access to the laboratory.

1 (out of 1) mandatory digital test in measurement techniques and correct use of laboratory equipment.

4 (out of 4) approved laboratory exercises.

Assessment The assessment is based on :

• Written project report (50 %)
• Oral examination (50 %)

Both parts needs to be passed individually to pass the course. Grading is scaled from A (highest) to F (lowest), with E as the minimum pass grade.

Re-sit exam: Oral exam will be arranged if any candidate received grade F in the previous ordinary exam.

No re-submission of the project report is offered.

The date for the exam can be changed. The final date will be announced at your faculty early in May and early in November.
