Impact of NOVEL HVDC Superconducting Circuit Breaker on HVDC Faults
2018The key obstacle of very large discharge current of the DC-link capacitor, Voltage Source Converter-based HVDC (VSC-HVDC) is it is vulnerable to the DC short-circuit faults. Superconducting fault current limiter (SFCL) is an effective option to minimize commutation failure and increase the steady-state stability to mitigate the fault and also limit or ...

A Comprehensive Review of HVDC Circuit Breakers and Protection Systems
2025 IEEE International Conference on Environment and Electrical Engineering and 2025 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe)The recent evolution of electrical systems, coupled with the rapid expansion of renewable generation sources, has encouraged the rapid growth of high-voltage direct current (HVDC) to transmit high power over long distances. In particular, for the future implementation of DC grids, the development of DC breakers is needed to ensure selectivity in fault ...

Considerations on energy absorption of HVDC circuit breakers
2014 49th International Universities Power Engineering Conference (UPEC), 2014This article deals with possible solutions for energy absorption in HVDC transmission systems. Depending on the converter topology high current slopes can appear in case of DC short circuits. Besides the handling of high currents itself, HVDC Circuits Breakers have to decrease the energy stored in line inductances in order to interrupt.

Fault Discrimination in HVDC Grids with Reduced Use of HVDC Circuit Breakers
2018 IEEE Power & Energy Society General Meeting (PESGM), 2018HVDC grids are currently considered to accommodate the integration of renewable energy sources into the power system. Since HVDC circuit breakers might at present incur a large investment cost, fault clearing strategies with limited use of HVDC circuit breakers have been recently proposed.

An Diode Clamped Multi-port HVDC Circuit Breaker for HVDC Grids
2019 IEEE 8th International Conference on Advanced Power System Automation and Protection (APAP), 2019In the process of fault isolation, many ultra-fast disconnectors of current-transferring HVDC circuit breaker (CT-DCB) need to be opened at the same time, which obviously reduces the operation reliability of CT-DCB and affects the fast recovery of the HVDC system.
