摘要：
The DC circuit breaker (DCCB) is the bottleneck of the development of DC transmission technologies. The operation time, cut off capacity and manufacturing cost restrict the promotion and application of DCCB. Based on the development of existing DCCB, the topology of an improved capacitor commutated DC circuit breaker (ICCB) with bidirectional interruption was proposed in this paper, in order to improve the fault-isolation and reclosing ability of VSC-HVDC systems. The working principle and parameter design of ICCB were elaborated, which can improve the interruption reliability and greatly reduce the manufacturing cost of the device. Finally, a test system of half-bridge MMC was built in PSCAD/EMTDC to simulate the ICCB and its fault isolation scheme, and the results were analyzed to verify the feasibility of the proposed scheme. © 2020 Chin.
