Subject aims expressed by acquired skills and competences

The aim of this subject is to acquaint students with basic kind of power system studies, the way of data mining and documentation, the simulation method and the way of reporting the results with clearly defined executive summary that assesses the presented outcomes.

Teaching methods

Individual consultations


The computer aided power system studies have significantly developed within last 30 years. Nowadays, these studies have become the common and indispensable part of large power system projects in electrical engineering. These studies are able to analyze the behavior under normal and contingency conditions and assess the dynamic stability of electric power systems, they are further able to optimize and design the protection device coordination, cable cross sections, switching and protective devices and other equipment which is a part of electrical installation.
