ECE 4314 - Electric Energy Distribution Systems

Course Description

Fundamentals of electric power distribution systems. Load characteristics. Modeling of distribution system components (line segments, voltage regulators, and transformers). Distribution flow analysis. Capacitor placement. Symmetrical components and calculation of fault currents. Protection of distribution feeders. Automation/control technologies to enhance reliability, resilience, and security.

Why take this course?

In addition to wide-area transmission grids, power utility companies own and operate distribution systems to serve customers. Power engineers at utility companies plan, design, operate, protect, and maintain distribution networks. There is a great need for distribution system engineers in the U.S. due to the shortage of the related workforce. Recent developments in smart grid and renewable energy provide new technologies for monitoring, control, operation, resilience, and cyber security of distribution systems. This course will provide new concepts that are important for the future distribution system engineers. All subjects in the analysis of distribution systems in this course involve concepts and calculations of AC circuits.
