#### Eligibility:

For single subject courses within Chalmers programmes the same eligibility requirements apply, as to the programme(s) that the course is part of.

#### Course specific prerequisites

Circuit theory, AC- and DC-circuits, Passive components and semiconductor components, jw-method.

#### 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)

- 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, the electric power production and consumption in Sweden. - Analyse and make calculations on: Equivalent circuit of transformers, transform impedances, voltage drop, losses, three-phase connections and autotransformers. Describe: The function of a transformer, the characteristics cables and overhead lines. - Make calculations on: Point of operation and grid integration for: Induction machine: Torque-speed curve, equivalent circuit, start performance, operation with frequency converter. Direct Current-machine: Equivalent circuit, Torque-speed function, speed control. Describe and explain the induction and DC-machine design and operation. Also describe the function of small ac/dc-motors and the synchronous generator. - Carry out calculations on: Single and three phase diode rectifier and dc/dc-converters with voltage and current time-functions. Describe the basic function of components and converter, harmonics of currents, PWM. - Describe. Electric safety regulations, risks, fuses, grounding system and protection system. Carry out electric machine experimental work in a safe way. 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.

Compendium.

#### Examination

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