变电站配置工具中SCL文件解析的分析与实现

Analysis and Application of Parsing SCL File in Substation Configurator

变电站配置语言(SCL)是IEC61850规定的基于XML的对变电站自动化系统(SAS)及其构进行描述的一种语言,它受IEC61850规定的统一的schema文件约束。变电站描述和配置工具生成不同类型的SCL文件,完成对整个变电站的配置。文章分析了配置工具中对SCL文件的解析分成两个步骤的原理,并提出了编辑和解析SCL文件时使用XML模板文件实现schema文件对SCL文件进行约束的方法。

IEC 61850 specifies a substation configuration language called substation configuration language(SCL) which is based on XML for the description of substation automation system(SAS) and its structure. It is qualified by SCL schema which are specified by IEC61850-6. The description and configuration tools of substation create different types SCL files to fulfill the whole configuration process. This paper proposed a method that parsing SCL file in configuration tool is divided into two steps. A XML template file is created to implement the schema restriction on SCL files in editing and parsing SCL files.
