The demand for electrical energy is still increasing. To keep the high grade of reliability of electrical distribution and also make it more economic and environmentally friendly, there are many projects going on: Renewable production of electric energy is installed and the international trade is increasing. Increased capacity of the transmission system is achieved by advanced supervision and control instead of the expensive building of new transmission lines. Higher utilization of the power system requires better understanding not only of the function of the separate components, and also of the characteristics of the whole system. The course is meant to give knowledge about systems for production, transmission and distribution of electric energy under normal and abnormal conditions. The power blackout on a national level is used as a thematic example throughout the course. The course presents the structure and characteristics or the electric power system, which are lectured and studied in classroom and computer exercises and practical tests within the laboratory work. In industry, computer calculations are used for the analyses of international power systems. This type of calculations is part of the course, as well as calculations by hand, used to enhance the understanding of the computerized calculations. The course has relevance for an environmentally sustainable development: Electric energy is the most important form of energy for our prosperity. The course teaches how the power system works and can be controlled as effectively as possible and thereby minimize our energy consumption.
