智能变电站VLAN配置表自动生成技术的研究和应用

Research and Application of VLAN Configuration Tables Automatic Generation Technology in Smart Substation

目前智能变电站过程层交换机的流量管理主要采用虚拟局域网(VLAN)划分的方法,该方法需要理解VLAN的工作原理,并根据信息流进行人工设计,效率不高。文中通过解析光纤物理回路文件(SPCD)和变电站配置描述文件(SCD),建立交换机的端口拓扑关系,分析各智能电子设备(IED)在交换机中的信息流,根据端口自动分配端口虚拟局域网标识(PVID),从而自动完成交换机中VLAN配置表的生成。文中设计了220 k V典型间隔VLAN配置表的自动生成的测试用例,通过测试证明,该方法可自动完成智能站交换机VLAN配置表的生成,按预期精细化控制流量走向,大大提高了现场的工作效率,具有一定的实用价值。

At present, the traffic management of the switches at the smart substation process level mainly adopts VLAN division method. Need to understand the working principle of VLAN and design artificially by information flow, so efficiency is not high. By analyzing the SPCD and SCD, the port topological relations of the switches are established, and the information flow of each intelligent electronic device （IED） device in the switch is analyzed, and the port VLAN ID is automatically assigned according to the ports （PVID） to auto-complete the generation of VLAN configuration tables in the switch. An automatically generated test case of 220 kV typical interval VLAN configuration table is designed. The test proves that this method can automatically generate the VLAN configuration table of intelligent station switch and control the flow direction according to the expected refinement, greatly improving the working efficiency of the site , has a certain practical value.
