基于 MAC 地址匹配的智能变电站网络设备拓扑动态识别

摘要

In order to realize network topology visualization and fast network fault location for smart substations,based on topology identifying methods for conventional switch networks,a dynamical topology identification approach is proposed for smart substation networks using media access control MAC address matching.In order to realize dynamical topology identification for smart substation networks including switches and intelligent electronic devices IEDs ,the approach matches information from MAC access tables,captured network packets,and substation configuration files.In addition,a Linux-based software tool is developed and applied in a simulation system to validate the proposed approach.%为实现智能变电站网络拓扑可视化和网络故障快速定位，文中在常规交换机网络拓扑搜索方法的基础上，提出一种基于介质访问控制(MAC)地址匹配的智能变电站网络设备拓扑动态识别方法。该方法以 MAC 地址为外键匹配交换机 MAC 地址转发表、断面数据报文和智能变电站配置文件，实现了智能变电站交换机网络和智能电子设备的拓扑动态识别。在 Linux 平台上开发了软件工具，并在实验室模拟系统中验证了该方法的可行性。
