High voltage DC grid is developing towards more terminals and larger transmission capacity, thus the requirements for circuit breakers (DCCB) will rise. The conventional methods only use faulty line DCCB to withstand fault stress, while this paper presents a coordination method of multiple DCCBs protect system. As many adjacent are tripped interrupt current, energy shared, requirement reduced. ...

Abstract The high‐voltage direct current (HVDC) power transmission short‐circuit fault protection is a big challenge, and it the main obstacle to promote HVDC multi‐terminal networks. A natural commutation topology (NCCT) of hybrid circuit breaker (DCCB) integrated with limiting proposed in this paper, which shares several obvious merits, such as lower peak current, shorter isolation time low t...

Recently the hybrid multi-port DC circuit breaker (MP-DCCB) is becoming popular in protecting HVDC grids, thanks to their reduction of power electronics devices. In this paper, an enhanced current-limiting DCCB (MP-CLCB) for multiple line protection proposed. The integrated fault current limiter (FCL) inside MP-CLCB can clear faster with slightly increased costs. To reduce energy dissipation re...

Enhanced active resonant (EAR) dc circuit breakers (DCCBs) are a promising set of recently proposed DCCB concepts. As other DCCBs, EAR DCCBs still require fast mechanical switch. The requirements on the actuator switch depend concept and grid derived here for an DCCB. Thomson-coil actuators (TCAs) can open close switches sufficiently to satisfy requirements. This work studies experimentally TCA...
