摘要(Abstract)：

直流断路器是构建多端直流输电和直流电网的关键设备,在分析直流断路器及其应用场景特点的基础上,提出直流断路器控制保护系统必须具备实时性、高可靠性、接口类型丰富和接口数量众多的关键需求。以基于负压耦合换流原理的混合式直流断路器为研究对象,设计了满足上述关键需求的直流断路器控制保护系统,包括分层分布式的系统架构、完善的功能配置方案和合理的接口方案,该系统在厂内直流断路器整机试验和张北工程现场试验中得到了验证。
DC circuit breaker is the key equipment to construct multi-terminal DC transmission and DC power grid. Based on the analysis of the characteristics of DC circuit breaker and its application scenarios, some key requirements are put forward that DC circuit breaker control and protection system must have real-time performance, high reliability, rich interface types and a large number of interfaces. With hybrid DC circuit breaker based on negative pressure coupled commutator principle as a research object, a DC circuit breaker control and protection system scheme that meets the key requirements described above is designed, including hierarchical distributed system architecture, perfect function configuration scheme and reasonable interface scheme. The DC circuit breaker control and protection system is verified by factory test of DC circuit breaker and field tests of Zhangjiakou-Beijing transmission project.
