Review of DC Circuit Breaker Technology for HVDC Application

With the development of HVDC transmission system, the research of direct current circuit breaker (DCCB) has drawn the attention of many scholars. This paper summarizes the new development of DC circuit breakers in recent years, including the auxiliary circuit and control method in DCCB. In addition, this paper introduces the DCCB with cascade module, device combination and test circuit for DC circuit breaker. The topology principle, advantages and main problems in high voltage direct current transmission (HVDC) application are discussed. The possible future development direction and related problems of DC circuit breaker are put forward.
