为实现智能变电站过程层物理链路图可视化,有效降低继电保护系统运行维护任务,本文基于SCD模型设计了智能变电站过程层物理链路图自动生成方法。首先详细介绍SCD文件数据处理流程,其次分析过程层物理链路典型结构,再次设计自动生成链路图过程,然后进行布局与走线合理规划,最后以简单实例验证自动成图方法。结果表明,其既能够实现物理链路图可视化,生成布局简单生动,走向清晰明了的链路图,又能显著提升维护检修效率与质量,值得大力推广与应用。

In order to realize the visualization of process layer physical link diagram of intelligent substation and effectively reduce the operation and maintenance task of relay protection system,this paper designs an automatic generation method of process layer physical link diagram of intelligent substation based on SCD model.Firstly,the data processing flow of SCD file is introduced in detail,then the typical structure of physical link in process layer is analyzed,the process of automatically generating link diagram is designed again,and then the layout and line planning are carried out.Finally,a simple example is given to verify the automatic drawing method.The results show that it can not only realize the visualization of physical link diagram,generate a simple and vivid layout,and move towards a clear and clear link diagram,but also can significantly improve the efficiency and quality of maintenance,which is worth popularizing and applying.
