PWRS 400
Course Information

This is a four-day course.

Course Base Fees: $2,400 USD

PWRS 400 provides power system fundamentals that underlie the material covered in the SEL University protection courses. It addresses elements of system analysis as well as system operation and control.


This course is intended for new electrical engineering graduates working in the power industry with little or no power background and for experienced engineers who want to refresh their knowledge and learn of new developments in the industry.


Day 1

  • Introduction to Power Systems
  • AC Circuits Basics
  • Magnetic Fields and Circuits
  • Power Transformers

Day 2

  • Induction Motors
  • Synchronous Generators
  • Power Lines (includes line-loading simulations)

Day 3

  • Power System Steady State (includes a power flow exercise)
  • Power System Operation (includes an economic operation exercise)
  • Power System Balanced Faults

Day 4

  • Symmetrical Components
  • Power System Unbalanced Faults (includes a fault study exercise)
  • Power System Transient Stability
  • Relay Protection

Note: This course teaches fundamental knowledge but does not provide hands-on experience with SEL relays.

Course Objectives

At the conclusion of this course, students can:

  • Describe the structure of modern power systems (generation, transmission, subtransmission, distribution, and consumption).
  • Describe the basic principles of operation: voltage and frequency control, real and reactive power flow control, economic operation, and steady-state and transient stability.
  • Describe modeling of different power system components.
  • Perform power flow and fault analysis of a complex power system using computer models.
  • Describe the method of symmetrical components and the sequence network interconnections to study series and shunt unbalanced faults.
  • Calculate the state of different power system components.
  • Create conceptual designs and improvements of power systems that satisfy the basic principles of operation.

Student Background and Knowledge

Before you attend this class, we recommend that you have the following:

  • A degree in electrical engineering or equivalent experience.
  • A basic knowledge of electrical circuits.
  • A working knowledge of trigonometry, basic calculus, and complex numbers.
