Technical Assessment on Self-Charging Mechanical HVDC Circuit Breaker

IEEE Transactions on Industrial Electronics, 2022
High-voltage DC (HVDC) circuit breaker is the necessary equipment for multi-terminal HVDC grids, which is a prospective power transmission method in the future. Therefore, the research about HVDC interruption ushered in an explosive development in recent years. The mechanical DC circuit breaker based on the pre-charged capacitor for current commutation

Damping HVDC Circuit Breaker With Current Commutation and Limiting Integrated

IEEE Transactions on Industrial Electronics, 2020
The fault current limiting in high-voltage dc (HVdc) grids is critical to reducing the breaking stress of dc circuit breaker and improving the breaking reliability. However, the existing HVdc circuit breakers rarely consider the rapid limiting of fault current in the breaking process.

Test Circuits for HVDC Circuit Breakers

IEEE Transactions on Power Delivery, 2017
High voltage direct current circuit breakers (HVDC CBs) are necessary for reliable and safe operation of future multi-terminal meshed HVDC grids. So far no commercially mature products of such equipment exist. A few industrial concepts as a result of advances in power electronics have been proposed and prototypes have been built.

Review on HVDC circuit-breaker tests

2020 4th International Conference on HVDC (HVDC), 2020
Research and development of HVDC circuit-breakers (CBs) is a spotlight as the existing and planning VSC-HVDC projects are in increasing need of HVDC CBs. However, at moment there are no universal standards can be referred to for designing, testing and operating an HVDC CB.

HVDC circuit breakers for HVDC grid applications

11th IET International Conference on AC and DC Power Transmission, 2015
High Voltage Direct Current (HVDC) transmission has been expanding due to rapid development of power electronics technology and by the need for connection of offshore/remote wind farms and large hydro power generators. An HVDC grid will be required to operate the healthy lines continuously, even if a voltage collapse occurs at the remote end.
