数字化变电站改造中需对传统的微机保护装置进行IEC61850升级改造。以线路微机保护为例，在硬件上增加通讯模块，使其通过以太网按照IEC61850通信标准对外通信。对此保护装置进行功能分解、逻辑节点和逻辑设备确定，对线路保护中的纵联差动保护进行了数据建模，完成了此装置的IEC61850的信息模型及其服务的建立。所使用建模方法对其它保护设备有较好的应用价值，对于学习和实践IEC61850标准有一定的借鉴意义。

It is necessary to update the traditional microprocessor-based protection device to meet IEC61850 in the transformation of digital substation. Taking microcomputer-based transmission line protection as an example, this paper adds communication module to the original hardware to realize its external communication through Ethernet to meet the IEC61850 communication standard. Decomposition of functions and identification of logical nodes and logical devices are performed for the protection device, and data model of longitudinal differential protection is build. Finally the IEC61850 information model and service are completed. The modeling method used in this paper has better application value for other protection equipment and good reference significance to the study and practice of IEC61850 standard.
