Description of the lecture

The two-day block event (V2Ü1) is divided into individual lectures in which different aspects of the topic are addressed. The event will be supplemented by intensive exercises and an excursion to an HVDC facility.

The course is primarily aimed at students in the Master's programme in Electrical Engineering or Business Administration and Engineering: Electrical Power Engineering. It is offered in both the summer semester and winter semester. The Registration for students must be done via the RWTHonline. The number of participants is limited due to the size of the room.

At the end of the course, a certificate of the academic achievement (4 CP) will be issued. The participation in both block lecture days, the intensive exercise and the passing of the exam are required for the issue of the certificate. The voluntary excursion will take place in the summer semester 2019 while the exact date will be announced later on. According to the official examination regulations, the course cannot be credited as a seminar.

The lectures are primarily held in German.

Course contents

The focus of the lectures is on:

  • Introduction to high-voltage direct current transmission technology
  • Basics of power electronic components
  • Line commutated converter (LCC) technology
  • Technology of voltage source converters (VSC)
  • HVDC overhead line systems
  • HVDC cable systems
  • Power transformers for HVDC converter stations
  • Control and protection systems for HVDC
  • Systems for FACTS (flexible AC transmission systems)
  • Integration of HVDC into the transmission network
  • Offshore connection with HVDC
  • HVDC Grids - A look into the future


Relevant Bachelor degree.

Educational Goals

Linking basic technical knowledge on the subject of high-voltage direct current transmission and its practical application.

After the successful completion of the course, the participants will be able to describe the goals and the state of the art of HVDC technology, explain the basic tasks and functions of the equipment of HVDC converter stations, identify the advantages and disadvantages of different designs and describe the various possible applications, e.g. the voltage support in AC systems. Furthermore, they have an insight into future challenges and developments while the acquired knowledge gives them the opportunity to deal with specific aspects of the HVDC topic putting their outcomes into the overall context.


Written examination: Multiple-choice/open-question test.
