Objectives

  • Learn in detail the basic structure, functional characteristics and protection schemes of the main components that make up a powers system, in particular generators, transformers, transmission lines, cables, loads, HVDC, Flexible AC Transmission System (FACTS) controllers, and Renewable Energy Sources (RES).
  • Understand the modeling and simulation of these components for detailed electromagnetic transients analyses, as well as phasor models for power flow and stability studies.
