Influence of capacitor-buffered hybrid DC circuit breaker on bipolar short circuit fault of three-terminal MMC-HVDC transmission system

open access: yesEnergy Reports, 2020
The flexible DC transmission system needs a DC circuit breaker to remove and isolate the bipolar short-circuit fault to prevent the excessive short-circuit current from damaging the DC transmission system.

Operating DC Circuit Breakers With MMC [PDF]

open access: yesIEEE Transactions on Power Delivery, 2018
High Voltage Direct Current (HVDC) grids may be protected from dc faults through the application of HVDC circuit breakers. Recent advances in dc circuit breaker technologies may allow faults in the dc grid to be cleared without a permanent loss of power to the connected ac grids.

Impact on Current-Interrupting Characteristic by Parameter Settings of Superconducting Hybrid DC Circuit Breaker

open access: yesEnergies, 2021
DC faults cause severe disruption in not only the DC system but also the AC system because the fault current is very large and rapidly increases. The DC circuit breaker used to separate the DC faults from the power system is still being researched, but ...

Bridge-Type Integrated Hybrid DC Circuit Breakers [PDF]

open access: yesIEEE Journal of Emerging and Selected Topics in Power Electronics, 2020
The inclusion of a large number of controllable semiconductor devices in conventional hybrid dc circuit breakers (HCBs) may significantly increase the cost of an HVdc grid protection scheme. In an attempt to reduce this cost, this paper proposes the use of two novel topologies of bridge-type integrated HCBs (BT-ICBs).
