A novel HVDC circuit breaker for HVDC application [PDF]

International Journal of Electrical Power and Energy Systems, 2019
Hybrid high voltage direct current circuit breakers (DCCBs) are capable of interrupting fault current within a few milliseconds, but this technology has high capital cost, especially in a meshed HVDC grid. To increase the economic competitiveness of hybrid DCCBs, this paper proposes a capacitor commutated dc circuit breaker (CCCB).
