Before choosing courseFEG3213 FACTS and HVDC in Electric Power Systems 10.0 creditsAdministrate About course

In this course, issues (or problems) that an electric power system may face will be discussed. Then, it will be shown that FACTS and HVDC systems may be a technical solution to these issues. It will also be discussed how these devices are designed and what functions they have. Then, basic mathematical models and control strategies will be derived based on which the impact of these devices on power system stability and damping will be analyzed.

Content and learning outcomes

Course contents

FACTS (Flexible AC Transmission System) and HVDC (High Voltage Direct Current) are controllable devices whose functions are to enhance the security, capacity and flexibility of power transmission systems. Application of these components in power systems implies an improvement of

  • transient stability
  • voltage stability
  • damping of power oscillations
  • optimal power flow

The course is given in English, and starts with a review of static and dynamic issues in power systems. As a technical solution to these issues, FACTS and HVDC will be presented. It will be shown that FACTS and HVDC may be a technical solution to these issues. It will be discussed in the course how these components are designed and also what functions they have. Then, basic mathematical models and control strategies will be presented for these components to analyze the impact of these components on power system stability.

Intended learning outcomes

Upon completion of the course the student should be able to

  • describe how FACTS and HVDC are designed,
  • explain and analyze their functions,
  • derive basic mathematical models for these components,
  • analyze the impact of these components on power system stability,
  • perform calculations on different control strategies for these devices.

Course Disposition

Lectures, lab, home exam and project.
