Strategic Performance Indicators (SPIs)

Outcome 1 (Students will demonstrate expertise in a subfield of study chosen from the fields of electrical engineering or computer engineering):
1. Understand the protection philosophy for electric power system and elaborate on the speed, dependability and security of protection systems.
2. Understand the protection requirements for all the major power devices in an electric energy system, such as generators, power lines, and transformers. Describe protection schemes for major power devices and compute settings for the main protection functions.

Outcome 2 (Students will demonstrate the ability to identify and formulate advanced problems and apply knowledge of mathematics and science to solve those problems):
1. Design and code a protective relay and demonstrate its operation with simulated data.
2. Develop algorithms and implementations for analyzing fault conditions for a small electric energy system under transient and steady state faults.

Outcome 3 (Students will demonstrate the ability to utilize current knowledge, technology, or techniques within their chosen subfield):
1. Design, test and be conversant of the main protection functions for component protection, such as overcurrent, directional, differential, distance, over/under voltage, over/under frequency, volts over hertz, out of step protection.
2. Design and implement special protection systems using traveling wave phenomena; design and implement special protection systems based on state estimation.
