The objectives of the training is to give a technical hands-on on HVDC VSC systems. It is organized in collaboration with RTE.

The training covers the following topics:

  • Introduction to VSC-MMC technology
  • Modeling and simulation of HVDC VSC systems with EMTP-RV
  • Control and protections of VSC-MMC stations
  • Specifications for HVDC VSC projects
  • Maintenance of HVDC converters

It gives practical and technical information on HVDC-VSC schemes and operations based on real projects.

Temporary EMTP-RV licenses will be provided to the audience. EMTP-RV tool will be used to illustrate concepts and performances of HVDC VSC systems.

Intended audience

This course is intended for engineers, researchers, operators and maintenance personnel, to provide
an up-to-date technical expertise for HVDC-VSC projects.

Training structure

The duration of the training is 5 days.
The training starts at 8:30 am and ends at 5:00 pm every day.
Lunch breaks are from noon to 1:00 pm.
