摘　　要：智能电网建设过程中配电终端起到了越来越重要的作用,功能也不断增强。本文针对配网建设中配电终端功能多样化,存储数据大等需求,提出了基于BerkeleyDB的配电终端设计思路。在嵌入式操作系统的基础上,实现了历史信息的快速存储、查询和删除等操作。搭建试验平台与简单文件存储方式进行了对比试验和分析,试验结论表明该设计方案存储效率高、查询删除速度快、占用CPU资源少,具有明显的优势。研发的配电终端已经成功应用在北京等地,运行结果可靠稳定,能够满足用户需求。The distribution terminal has played an increasingly important role in the process of building the smart grid, function has also been enhanced. According to the construction of distribution network with terminal functional diversification and large data storage requirements, a design idea based on Berkeley DB is proposed in this paper. The rapid storage, query and delete operation of history information is realized in the embedded operating system. Build platform to compare and analysis with simple file storage, the result shows that the design has obvious advantages in the storage efficiency, query and delete speed, cpu usage. The distribution terminal unit has been successfully applied in Beijing and other places. The result of application is reliable and stable and can meet user needs.
