EG2120 FACTS and HVDC in Electric Power Systems 7.5 credits

FACTS och HVDC i elkraftsystem

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

Course information

Content and learning outcomes

Course contents *

FACTS (Flexible AC Transmission System) and HVDC (High Voltage Direct Current) transmission are power electronics-based devices whose functions are to enhance the capacity, security and flexibility of power transmission systems. Application of these components in power systems implies an enhancement of transient and voltage stability, increase of power oscillation damping (POD) and improvement of power flow under undisturbed or post-fault conditions. The course starts with a short review of some issues (or problems) that an electric power system may face. Next it is discussed how these components are designed and what their main properties are. The following lectures focus on the use of the FACTS and HVDC transmission as technical solution to the issues described earlier. Basic mathematical models and control strategies used to analyze the impact of these devices on power system stability are presented. Most part of the analysis is dedicated to POD which is the main topic of this course. Lectures for the use of the main features of the necessary software are scheduled.

Intended learning outcomes *

After passing the course, the student should be able to

  1. create basic mathematical models for controllable components (FACTS and HVDC) and based on these be able to carry out load flow analysis and stability analysis of electric power system and apply different control strategies for these controllable components
  2. present, analyse critically and explain simulation results about the effect of controllable components on power system stability and damping,.
