- Synopsis:
-
The aim of the subject is to acquire wider knowledge of transients in electrical networks. After obtaining necessary information about parameters and characteristics of particular elements, the main attention is paid to the methodology of solution of symmetric and non-symmetric, static and dynamic, particularly non-standard transients in power systems. The course is supplemented with indispensable chapters of mathematics and physics of non-linear dynamic systems with application to some typical phenomena in power systems.
