Development of HVDC Circuit Breaker and its Interrupting Test

IEEE Transactions on Power Apparatus and Systems, 1982
The authors have developed a DC circuit breaker (DCCB) which interrupts a DC current by injecting a high-frequency reverse current from a commutating capacitor to be superposed to DC current and forcibly creating a current zero point. A breaking part consists of a vacuum interrupters or a SF6 gas, interrupters of the most advanced design connected in ...

HVDC Circuit Breakers -- Test Requirements, Methods and Circuits

2021
In der Industrie wurden aktuell mehrere Konzepte von Hochspannungs-Gleichstrom-Leistungsschalter (HGÜ-Leistungsschalter), basierend auf unterschiedlichen DC Unterbrechungstechnologien, in Prototypen überführt. Nur wenige dieser Prototypen wurden zu einem industriellen Produkt weiterentwickelt und durchliefen eine Inbetriebnahme.

HVDC Circuit Breaker Development and Field Tests

IEEE Power Engineering Review, 1985
With 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), 2019
Test 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.

Impact of NOVEL HVDC Superconducting Circuit Breaker on HVDC Faults

2018
The 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), 2014
This 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), 2018
HVDC 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), 2019
In 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.
