Advanced Power System Analysis in Electrical Network Using ETAP Power Station Course
Course Overview:
This course delves deeply into the theories and the practical application of power system modeling, as well as the analysis of fault currents. Participants will learn about circuits using MVA, P.U. systems, and symmetrical components, as well as the need for short-circuit calculations, the repercussions of the fault, and system modeling through manual and software methods.
The course encompasses countless topics such as balanced and imbalance load flow modeling, motor starting, voltage reduction, and capacitor placement optimization, to name a few. There's more, it encompasses switchgear engineering, relay sets synchronization, arc flash issues, earthing grid development, and harmonic complications.
This is a practice-oriented course for engineers and other professionals working in power systems and combines traditional technologies and software with simulation technologies such as ETAP, CYME, and SKM.
