摘要: 介绍IEC61850系列标准中的变电站配置描述语言的文件结构,阐述系统的配置流程及各种数据文件的交换过程,提出在XML文件管理维护上采用纯XML数据库技术。直接将XML文本文件作为存储单元。创建2个索引文件,运用传统的B+树数据结构建立索引。针对XML文件的特性,采用XML路径语言XPath表达式的方法进行文件查询。

Abstract: This paper introduces the document structure of the Substation Configuration description Language (SCL) in the IEC61850 standard. It expatiates the configuration flow of the system as well as the exchange process of the data document, and brings forward to use the Native XML Database(NXD) technology in maintaining the XML documents. It takes the XML text file as the store unit. The system creates two index file and uses the traditional B+ tree data structure to set up the index. It uses the XPath expression to query in the XML file.

Key words: IEC61850, Substation Configuration description Language(SCL), Native XML Database(NXD)
