本文介绍了IEC 61850中SCL文件的基本结构；分析了MMS-Lite中SCL解析的数据结构以及实现过程；针对MMS-Lite在解析中所生成的信息树形结构中缺乏IED设备及GOOSE等信息的弱点，对MMS-Lite的源代码进行改进，得到更加完整的解析信息量，有利于更全面了解变电站状态。%This paper introduces the basic structure of SCL file. The data structure and implementation process of MMS-Lite for SCL file parse are analysised. As the classical tree structure of MMS-Lite paraser lacks the information of IED equipments and GOOSE, the authors modified the source codes of MMS-Lite to get such information. Finally a more complete information structure was gained, and it is more helpful for showing of the state of the substation.
