Protection of multiterminal HVDC grids continues to be a topic of great interest, with a decade of research now leading to the first industrial systems with DC grid protection. There are still, however, open questions as to the most effective system design, as well as regarding interoperability, functional requirements and specifications. Functional testing of protection systems (e.g. protection relays or IEDs) goes some way towards de-risking the deployment of these still novel technologies. This presentation will look into HVDC protection systems and focus on testing performed by KU Leuven / EnergyVille – including demonstration and validation of functional performance, and looking towards future standardisation of HVDC protection functions, functional requirements/tests, and design/specification of protection systems.
