LE/EECS 4627 (3.00)

Power System Protection

Description

This course reviews the fundamentals of short-circuit fault analysis and symmetrical components for three-phase systems. The concept of relaying to protect a power system during faults and to maintain the integrity of the system is discussed. Introductory descriptions of electromechanical, static, and digital protective relays are presented and their features are elaborated. The measurement devices used in protection systems are introduced, and their non-ideal features are discussed. The operating principles of various types of relays such as overcurrent, differential, and distance relays are discussed and some coordination techniques and potential applications are covered. In addition, different types of pilot protection schemes implemented using distance and directional relays are introduced. Throughout the course, computer simulations of power systems are used to analyze protection functions. Prerequisite: LE/EECS 3622 4.00 or LE/EECS 4622 4.00

Tips: you can drag and drop the boxes to clone them to different sections or groups within a prerequisite equation.
