摘　　要：随着电力负荷的迅速增长和用户对电能质量要求的不断提高,传统配电系统面临新的挑战。直流配电技术在提高电能质量方面的巨大潜力引起学者们的关注。由于缺乏成熟、经济的直流断路器和实际运行经验,保护技术成为制约直流配电系统发展的瓶颈。鉴于此,概述了直流配电系统保护技术研究的发展现状,从直流配电系统的概念出发,系统阐述了保护技术研究的困境,明确了保护分区与故障类型,并指出了直流配电系统故障与保护的特殊性。然后综述了直流系统故障隔离及限流装置的发展现状,总结了直流配电系统的保护策略。最后对直流配电系统保护的技术研究做出了展望。With rapid growth of power load and power consumers’ ever-growing demands on power quality, traditional distribution system has been faced to new challenges, thus special attentions are paid to the huge potential of DC distribution technology in improving power quality. Being short of mature and economic DC circuit breakers and their practical operational experiences, protection technique becomes the bottleneck that restricts the development of DC distribution system. Firstly, present developing situation of protection technology for DC distribution system is summarized, and starting from the concept of DC distribution system the dilemma in the research on protection technology for DC distribution system is presented; the protection zone and fault types are clarified, and the particularity of protection for DC distribution system faults is pointed out; a review on current development of fault isolation devices and fault current limiters for DC distribution system are given and the protection strategy of DC distribution system is summarized; finally, the technical research on protection for DC distribution system is prospected.
