DC Protection Activities in ETCH
Speaker: Geraint Chaffey, Ph.D.
Dr. Geraint Chaffey received the M.Eng. degree in electrical and electronic engineering from Cardiff University, Cardiff, U.K., in 2012, and the Ph.D. degree from Imperial College London, London, U.K., in 2017. His doctoral thesis was titled “The Impact of Fault Blocking Converters on HVDC Protection.” He is currently a Research Expert at KU Leuven/EnergyVille, Belgium, where his research is mainly focused on the design and demonstration of HVDC protection systems. Geraint has a background in HVDC protection and real time simulation for power systems, and contributes to harmonisation in these fields for CIGRE, IEEE and IEC.

The protection team at the Energy Transmission Competence Hub (Etch) look into key protection-related challenges for future converter and cable dominated power systems. Work includes HVDC protection system design (for multiterminal HVDC grids, and electrical energy hubs), assessment of AC protection in converter dominated systems (and ways to improve co-design between converter control and AC protection), development and functional testing of HVDC protection algorithms, and research towards enabling future multivendor HVDC grids. This presentation will summarise recent work in the Etch protection team, as well as briefly presenting the principles and progress towards a competence hub for electricity transmission (Etch).
