Learning unit contents

High Voltage Direct Current (HVDC) technology offers higher flexibility for electric power transmission.  It is an active and fast growing research area and more and more HVDC applications are deployed worldwide. This course covers the fundamentals of High Voltage Direct Current (HVDC) systems, used for power transmission in electric energy grids. It is made up of two main parts.
1. Description of the main components of HVDC systems and their control :

  • Recalls : principle of power AC/DC  and DC/AC power conversion
  • HVDC power converters : Line-Current-Commuted (LCC) converters and Voltage-Sourced (VSC) converters
  • Main components of HVDC systems : transformers, smoothing reactors, active filters, lines and cables
  • Control of HVDC converters and systems
2. Use of HVDC systems for electric power transmission
  • Basic HVDC configurations
  • Interaction between AC and DC systems
  • Overview of present and future applications
  • Fault behavior and protection of HVDC systems
  • Multiterminal HVDC grids
 

Learning outcomes of the learning unit

At the end of the course, the student will be able to :

  • demonstrate a knowledge and understanding of the various types of HVDC technologies;
  • justify the higher flexibility offered by the interconnection of  DC and AC system for electric power transmission;
  • demonstrate its ability to model  basic components of HVDC systems and analyze the corresponding  simulation results.
The case studies presented and the personal homeworks will also give him/her the opportunity to study a large-scale nonlinear system, to improve its understading of such systems and to train his/her presentation skills.

Prerequisite knowledge and skills

Basic knowledge in power system components and analysis. Basic knowledge of the Matlab tool.

Planned learning activities and teaching methods

The course is made of theoretical presentations and practical sessions dedicated to exercises and analysis of relevant case studies.  
 

Mode of delivery (face-to-face ; distance-learning)

face-to-face

Recommended or required readings

The learning material and the complementary documents will be provided by the teacher on-line, via myULg.

Assessment methods and criteria

Theoretical part : oral exam.
Practical part : personal homeworks dealing with small case studies using MATLAB,  written report and oral presentation.

Work placement(s)

Organizational remarks

The course is taught during the second quadrimester, Friday morning.
