Aim:
The overall aim is to provide overall knowledge of the energy system with emphasis on the electrical system. In the end of the course the student should know about how to:
- explain and understand how the electrical grid is constructed and controlled
- explain and understand critical stability issues and the how safe operation is maintained
- perform calculations on three-phase power transfer and draw equivalent per-phase-circuits
- perform calculations on phase-compensation of reactive loads
- perform calculations on symmetrical and unsymmetrical three phase systems
- perform calculations on three phase power transformer
- describe the principle function and perform calculations of different electrical machines such as
- Asynchronous machine
- DC-machine
- Synchronous machine
perform calculations in power electronics with thyristors and diodes and regulators
explain and understand the principles of different battery-technologies and what the implications for the end user is

Course contents:
The course will give basic knowledge about energy systems and examples of technical applications in various areas. The principles of different kinds of equipment in the power and heating areas will be treated. Here electric power has a central role.
- Three phase systems and calculations (phase diagrams, synchronous generator, the jw-method etc.)
- Single- and three-phase transformers
- DC machine (machine types, electromechanical relationships, speed-control, efficiency and losses)
- Asynchonous machine (structure, electromechanical relationsips, efficiency and losses)
- Power electronics (rectifiers, diodes, thyristors, inverters)
Using the above as foundation, technical areas that are relevant from an energy perspective will be studied.
- Energy conversion
- Batteries
- Charging
- "Smart grid"
- Infrastructure
