- Electrical power engineering fundamentals - Fundamentals of transient phenomena in power grids - Magnetic circuits and transformers - High voltage power lines and substations In this subject, concepts taught in the previous subjects are used. It is particularly important to have acquired the basic knowledge taught in "Electrical power engineering fundamentals" and to be proficient in the analysis of electrical circuits. In addition, it is recommended to simultaneously study "Electric rotating machines", in which the synchronous machine model (generator) is studied.

The student will be able of analysing electric power systems in steady-state conditions, using using basic tools as per-unit quantities and load flow algorithms, and also under fault conditions (symmetrical and unsymmetrical). The student will acquire basic knowledge about the transient stability problem and the capability to analyse the transient stability in simple cases. The student will acquire basic skills in using commercial software for power system analysis.
