摘　　要：配电终端存在量大且分布广、故障率高、运维难度大等特点,数字孪生技术为配电终端从“被动运维”向“主动运维”转变提供了新思路。该文提出了配电终端数字孪生体的建模原则、五层建模架构和建模方法。其中,为实现数字孪生体与外部系统的信息交互,提出基于IEC 61968规范的CIM(Common Information Model)模型的扩展方法。最后以健康评估为例,构建了基于数字孪生体的配电终端健康评估构架和信息流。研究成果可为配电终端健康评估、远程运维等具有配电自动化发展趋势的高级应用奠定模型基础。Distribution terminals have the characteristics of large quantity and wide distribution,high failure rate,and great difficulty in maintenance.Digital twin technology provides a new idea for transforming distribution terminals from“passive maintenance”to“active maintenance.”This paper proposes the modeling principles,five-layer modeling architecture,and modeling methods for the digital twin of distribution terminals.An extension method of the CIM model based on the IEC 61968 specification is proposed to achieve information exchange between digital twin and external systems.Finally,taking health assessment as an example,a distribution terminal health assessment framework and information flow based on digital twin are constructed.The research results lay a model foundation for advanced applications with the development trend of distribution automation,such as distribution terminal health assessment and remote maintenance.
