Multi‐Layer MTDC Protection: Design and Simulation Assessment

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This study proposes a novel multi‐layer protection architecture for multi‐terminal DC systems that separates fault current‐limiting and interruption functions. By combining a thyristor‐based fault current limiter with an active resonance circuit breaker, the scheme significantly reduces peak fault currents and di/dt stress, enabling a more compact ...
