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 devices to power systems implies an enhancement of transient and voltage stability, increase of power oscillation damping (POD) and improvement of power flow under normal operations or post-fault conditions. The course presents basic mathematical models and control strategies for being able to analyse, how these devices affect power system stability. Most part of the analysis is dedicated to POD which is the main topic of this course. A part of the course shows how one uses the most important functions in the necessary software.
EG2121 FACTS and HVDC in Electric Power Systems 7.5 credits
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.
