HVDC Circuit Breakers -- Test Requirements, Methods and Circuits
2021Recently, several industrial concepts of high-voltage direct current (HVDC) circuit breakers (CBs) have been developed into prototypes, and few have been installed in service. However, due to a lack of operational experience, there exist no clearly defined requirements that the HVDC CBs should satisfy.

HVDC Circuit Breaker Development and Field Tests
IEEE Power Engineering Review, 1985With the growth of direct current transmission, the need and scope of application for a high voltage direct current circuit breaker have increased. This paper reports on the development of two different dc breaker prototypes and full scale field tests of these breakers on the ±400-kV, 1360-km long Pacific DC Intertie.

Synthesis Test Control of HVDC Circuit Breaker
2019 5th International Conference on Electric Power Equipment - Switching Technology (ICEPE-ST), 2019Test technology is important to evaluate the performance of DC circuit breaker. The synthetic test method is mainly used in high-capacity breaking test. In this paper, a practical and feasible control scheme is designed to the synthetic test circuit. The control system is based on Digital Signal Processor.

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.

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 ...

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.

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 ...
