Advantages

Full-detailed system tests to meet the needs of future power systems: from concept over conformity with new standards to
full system integration.
Our experienced team offers:

  • Expertise on power system modelling (especially HVDC)
  • Protection relay testing (including IEC 61850)
  • Power Hardware in the Loop (P-HIL) testing through a virtual grid integration of new components (e.g. converters, battery systems, …)

Applications

  • Pre-tender spec validation for new grid assets
  • Testing performance and configuration of new equipment
  • Offline investigations of non-trivial fault situations
  • Training personnel (operational and configuration of equipment)
  • Verification of grid connection set-up
  • Grid code compliance testing
  • Pro-active testing of future standards and protocols
  • Interoperability testing at neutral ground
