智能变电站ICD/CID/SCD模型内容差异检查方法及工具

Difference checking method and software of the ICD/CID and SCD in smart substation

针对目前智能变电站中ICD/CID之间与SCD中对应IED内容的差异不宜查找的问题,研究了一种多种文档内容差异检查方法及其工具。针对SCD、ICD、CID的语法特点,采用堆栈技术,获得各节点的开始行与结束行号。以两侧节点为完整单位,对节点的标签名和关键属性,进行两侧的交叉检查,找出两侧相同节点,并给出其中非关键属性的顺序错乱、属性值不同、内容不同等多种差异情况。能够对两侧同名节点的开始与结束行进行并列显示,直观同步地对照展示出两个文件中各种差异细节,并能切换到原始文档的相应位置。多个变电站的运行实例验证了该差异检查方法及其工具的有效性。该工具能够提高多个不同文档之间差异检查的准确性和效率。

To solve the problem of differences checking among the ICD/CID and IED of SCD in intelligent substation, a difference checking method as well as the tool is proposed. According to the grammatical features of SCD, ICD and CID, the stack technology is adopted to obtain the starting and ending line number of the nodes. As the complete units, the bilateral nodes join the cross checking on the tag name and key attributes to find the same nodes, and the differences of the non-key attributes, such as the out-of-order, different attribute values and contents. The starting and ending line of the same nodes on both sides can be displayed side by side. The details of differences in two kinds of files can be displayed intuitively and synchronously, as well as switched to original location of the document. The examples of typical substations illustrate the effectiveness of the proposed method. The tool can improve the accuracy and efficiency of difference checking among multiple documents.
