Design of test-circuits for HVDC circuit breakers

2015 3rd International Conference on Electric Power Equipment – Switching Technology (ICEPE-ST), 2015
DC circuit breakers are essential components in the protection of multi-terminal and meshed DC grids. So far, no practical application of HVDC circuit breakers is known and intense research is being carried out regarding various concepts, practical realization and ultimately testing of such devices. In the present contribution, several breaker concepts,

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 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.

Switching Overvoltages and Polarity Reversal in Presence of HVDC Circuit Breakers

2023 AEIT HVDC International Conference (AEIT HVDC), 2023
The recent development of High Voltage Direct Current circuit breakers (HVDC CBs) prototypes may introduce many potential advantages for HVDC links in terms of flexibility and possible meshing. However, introduction of circuit breaker in HVDC links also prompts the need for a detailed assessment of switching overvoltages and polarity reversal, which ...

HVDC Circuit Breakers -- Test Requirements, Methods and Circuits

2021
Recently, 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.

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.
