摘　　要：以短路故障切除与提高供电可靠性为目标的直流系统控保技术是发展新型电力系统的前期攻关重点之一。基于半导体组件的混合式直流断路器做为核心部件已进入工程示范。为解决断路器的高成本以及试运行中出现的可靠性等问题,文中提出了新的组合式直流断路器系统拓扑,把常规直流分支系统中的断路器代之以机械式开关。可大幅度降低整体成本与故障率。基于换流原理的快速直流断路器分闸速度可满足故障电流的发展,有望直接用于直流系统的控保。尝试用交流配电自动化的SCADA概念重建软件平台,创新直流配电系统拓扑,以更高的可靠性与经济性优势,为分布式多种能源智能组网给出更好的选择。The control and protection technology of DC system with clearing short-circuit fault and improving power supply reliability as the objective is one of the key technology to develop new power system.The hybrid DC circuit breaker based on semiconductor components has been applied for the pilot project as the core component.In order to solve the problems of high cost and reliability in operation,a new combined DC circuit breaker system topology is proposed in this paper,the circuit breaker in the conventional DC branch system is replaced by the mechanical switch.It can greatly reduce the overall cost and failure rate.The opening speed of the fast DC circuit breaker based on the converter principle can meet the development of fault current and is expected to be used directly for the control and protection of DC system.The software platform with the supervisory control and data acquisition(SCADA)concept of AC distribution automation is tried to be rebuilt to innovate the topology of DC distribution system and give a better choice for distributed multi energy intelligent networking with higher reliability and economic advantages.
