Small-Scale HVDC Circuit Breaker [PDF]
IEEE Transactions on Components, Packaging and Manufacturing Technology, 2017 Circuit breakers are anticipated for fault isolation in multiterminal HVdc networks. However, there are remaining challenges concerning the circuit breaker topology and operation. The passive oscillation principle circuit breaker is one of the topologies under consideration, the design of which requires examination of the arc characteristics.

HVDC Circuit Breakers: A Comprehensive Review [PDF]
IEEE Transactions on Power Electronics, 2021 High voltage direct current (HVDC) systems are now well integrated into AC systems in many jurisdictions. The integration of renewable energy sources (RESs) is a major focus and the role of HVDC systems is expanding. However, the protection of HVDC systems against DC faults is a challenging issue that can have negative impacts on the reliable and safe ...

A novel HVDC circuit breaker for HVDC application [PDF]
International Journal of Electrical Power & 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).

Interruption limits of mechanical circuit breakers and circuit upgrades for current injection in HVDC circuit breakers [PDF]
High Voltage, 2020 Current injection circuit breakers consist of a mechanical interrupter (MI) with a current injection and an energy dissipation branch in parallel. The performance of the complete device is largely determined by mechanical operation time and interruption performance of the MI.
