摘要：

提出一种基于数据驱动的智能变电站虚回路自动生成与自主校验方法。借助文档对象模型（document object model，DOM）方式快速提取历史变电站配置描述（substation configuration description，SCD）文件的虚连接信息，并构建历史SCD数据库，实现待设计智能电子设备（intelligent electronic device，IED）信息与历史IED信息的精确匹配，进而提出虚连接自动生成方案。考虑实际应用中可能存在的误连、漏连问题，提出构建标准模板库对自动生成的虚回路进行校验，并利用可视化技术实现预警，提醒设计人员对虚回路进行新增与修改。基于实际智能变电站案例验证了所提方案的准确性。

Abstract:

A data-driven intelligent substation virtual loop automatic generation and independent verification method is proposed. The virtual connection information of the historical substation configuration description (CD) file is rapidly extracted by using the document object model (DOM) method, and the historical SCD database is constructed. The precise matching of the information of the intelligent electronic (IED) to be designed and the historical IED information is realized, and then the automatic generation scheme of the virtual connection is proposed. In view of the problems ofconnection and missed connection in practical application, the standard template library is constructed to verify the virtual connection generated automatically, and the visualization technology is used to realize the alarm, reminding the to add and modify the virtual connection. The correctness of the proposed method is verified based on an actual intelligent substation case.

Key words: automatic generation of virtual circuits, autonomous verification of virtual circuits, visualization of warnings
