Jan. 14 - Mar. 8, 2020
This course is the first of two line design courses, and is intended to teach students the basic process for designing an overhead transmission (or distribution) line. Modules include:
- Terrain and Alignment
- Structure Spotting
- Line Design & Analysis
- Construction Package
Course assignments begin with fundamental exercises to establish a line route. After the line route is established, an actual line design will be developed and loads based on design criteria, standards, wire tensions, and weather inputs will be applied. Structure and foundation evaluations will then be performed from the load data. Once the structures and the foundations are evaluated, students will then spot (or locate) structures along the alignment.
Finally, clearance analysis and other verifications of an acceptable line design will be performed and the resulting design artifacts will be produced to complete a simple construction package. Course assignments will involve the use of survey data, drawings, mathematical formulas, and manufacturers' data.
The course begins with a review of basic concepts of power systems, their components and how they are inter-related. Then an overview to the topology and players of the North American power grid will be covered. The main portion of the course will refer to modeling of power systems, short circuit calculations, and load flow algorithms and methods. Students will learn how to apply these fields with theory and case studies in topics such as voltage regulation, VAR control, and relay setting and coordination. The course wraps up with a brief segment on harmonic analysis and filter design.

The next two weeks are taught by Tarlochan Sidhu, an Electrical Engineering Department Chair at a major North American University with extensive industry experience. His research experience and interests are specifically in the fields of power system protection and monitoring. His work involves the design, implementation and testing of relays and power system instrumentation that uses digital signal processing, artificial intelligence techniques and other novel methods. Students will learn how to calculate currents and voltages during balanced and unbalanced short circuits with this instructor.
