Traveling Waves in Power Systems for Electrical Engineering

When high-voltage surges travel along transmission lines, understanding wave propagation is critical to preventing catastrophic equipment failure. This text-only course provides a clear, step-by-step introduction to traveling waves in power systems, designed specifically for engineering students and entry-level power engineers. You will learn how electrical disturbances behave when they encounter changes in line characteristics, helping you build a strong foundation in power system transient analysis. By completing this course, you will be able to analyze wave behavior mathematically and predict how surges interact with different terminations and junctions. You will gain the analytical tools needed to calculate wave reflections and ensure system reliability. What you'll learn: - Understand the foundational physics and mathematical equations of traveling waves in power lines - Calculate reflection and transmission coefficients for both voltage and current waves - Analyze wave behavior at the boundary of two lines with different characteristic impedances - Evaluate transient responses at open-circuited, short-circuited, and reactively terminated line ends - Apply Bewley lattice diagrams to track multiple wave reflections over time - Practice solving practical transient surge problems through structured written exercises This course begins with essential terminology, wave definitions, and the derivation of the wave equation. From there, you will progress through single-junction reflections, multi-line junctions, and practical surge protection concepts. Each section includes detailed written derivations and step-by-step solved examples to reinforce your understanding. This course is designed for undergraduate electrical engineering students, junior power system engineers, and anyone preparing for technical exams in power systems. No prior experience with transient analysis is required, though a basic understanding of AC circuit theory and differential equations is helpful.
