Course Description and Learning Goals:

Students who complete this course will have gained a theoretical and applied understanding of power system protection. The performance of
instrument transformers, transducers, protective relays, and circuit breakers is first addressed. These devices are then integrated into coordinated
protective systems for generators, transformers, transmission lines, reactors, capacitor banks, system buses, etc. Although basic protection concepts
are hardware-independent, the application of electromagnetic, solid state, and microprocessor-based relays will also be discussed. Trade-offs
between reliability, selectivity, speed, simplicity, and economy are emphasized. A hands-on lab project, using state of the art equipment, will also be
completed during the course.

Topics Covered (depending on priorities and available time):

Review: system protection philosophies, system grounding, circuit breakers, fuses.
Relay input sources: VTs, CTs, CVTs, CCVTs, optical voltage and current transducers.
Fundamental protection concepts: time-inverse, differential, directional impedance, etc.
Generator protection (differential, negative sequence, loss of excitation, out of step, etc).
Motor protection (ground fault, locked rotor, undervoltage, phase rotation, etc).
Bus, reactor, capacitor bank protection.
Transformer protection (differential, sudden pressure, over temperature, low oil, etc).
Line protection (directional comparison, blocking, unblocking, transfer trip, etc).
System stability, reclosing, and load shedding.
Communications (pilot wire, power line carrier, microwave, fiber optics), SCADA, etc.

Prerequisite Material

Concurrent with EE4222, else by instructor's permission. Basic knowledge of the per unit system, symmetrical components, and short-circuit calculations is required. Typically, we adjust the schedule of covered material and avoid topics related to symmetrical components until you're covering them in EE4222.
Click here for outline - Power system protection draws on all areas of Electrical Engineering. We make use of a foundation of circuit analysis, electromagnetic energy conversion, knowledge of behaviors of transformers, generators, transmission lines, and motors, as well as traditional power systems analysis (i.e. EE 4221 and EE 4222). We can make use of every other area of EE: Electromagnetics, controls, electronics, computer hardware/software, microprocessors or embedded processors, signal processing, communications, etc.
