Eligibility:

In order to be eligible for a first cycle course the applicant needs to fulfil the general and specific entry requirements of the programme(s) that has the course included in the study programme.

Course specific prerequisites

Circuit theory, AC- and DC-circuits, Passive components and semiconductor components, jw-method and complex numbers. Recommended courses are Circuit analysis (EMI083, EMI084) and Introductory course in mathematics (TMV156/TMV157) or similar.

Aim

The students will, after this course, understand the basic principles of electric power components and systems, as well as know the possibillities and limitations of them. Besides that, they will also know important concepts and calculation methods.

Learning outcomes (after completion of the course the student should be able to)

1. Carry out calculations on: Three phase system, active and reactive power, phase-compensation, voltage drop, transmission on cables and overhead lines.
- Describe: The basic structure of the electric power system, frequency control, voltage control. The characteristics of cables and overhead lines.
2. Carry out calculations on: Equivalent circuit of transformers, voltage drop, losses, three-phase connections and autotransformers.
- Apply: Impedance transformation.
- Explain: The function of a transformer.
3. Carry out calculations for the induction machine on: Equivalent circuit, torque-speed characteristics and point of operation, start performance, no-load condition, operation with frequency converter and grid integration.
- Explain: The design and working principles of the induction machine, start methods and single phase induction motor.
4. Carry out calculations for the direct current (DC) machine on: Equivalent circuit, torque-speed characteristics and point of operation, speed control and grid control.
- Explain: The design and working principles of the DC machine and the universal motor. 
5. Explain: The design and working principles of the synchronous generator.
6. Carry out calculations on: Single and three phase diode rectifier and DC/DC-converters with voltage and current time-functions.
- Explain: The basic function of components and converter, harmonics, applications and pulse width modulation (PWM).
7. Carry out calculations on: three phase short circuits.
- Describe: The theory behind short circuits.
8. Describe: Principles for electrical installations and equipment used.
9. Conduct: Electric power laboratory experiments considering the personal safety and the equipment integrity.
- Apply: Relevant parts of laws and statutes related to electrical installations.
-Explain: Fuses, grounding systems, ground fault breakers and risk associated with electrical installations.
10. Perform: Project work in small groups with given input data.

Content

1. Electric power systems: Electric supply, Power networks, Transmission capacity, Voltage drop, Losses and Phase compensation.
2. Power system components: Transformers, Cables and Overhead lines.
3. Electrical drives: Induction machine, DC-machine, Synchronous generator, Speed regulation.
4. Power electronics: PWM-principles, Components, DC-converters, Rectifiers, Inverters.
5. Safety: Safety instructions, Risks and protection.

Organisation

The course is based on lectures and exercises and it aims at teaching the basic facts, important principles and mathematical methods. This part is tested in a written exam after 7 weeks. The other half of the course is based on larger problems which the students solve by themselves. Teaching time is spent on answering the students questions about the problems and to discuss their solutions with them. This part aims at giving the student a deeper understanding of the subject as well as making them more experienced in solving unknown problems. This part of the course is tested in an oral exam. Further more, there are three laboratory exercises to have experience with electricity safety and operation of electrical machines.

Literature

Compendium. Tutorial exercises.

Examination including compulsory elements

Written and oral examination. The grade is a combination of written exam and project work with oral exam.
