摘要(Abstract):
目前智能变电站过程层交换机采用静态组播方式时需要人工配置,导致工作量增大,自动化程度不足。通过解析SPCD文件和SCD文件,建立交换机的端口拓扑关系,分析各IED在交换机中的信息流,可自动完成交换机中静态组播表的生成。设计了220 k V典型间隔静态组播表自动生成的测试用例,经测试证明,该方法可自动生成智能变电站交换机静态组播表,最小颗粒度控制了流量走向,大大提高了现场工作效率,具有一定的实用价值。
Static multicast in intelligent substation process layer switch needs manual configuration, which results in heavy workload and automation deficiency. By SPCD and SCD file analysis and topological relation establishment of switch interface, the information flow of IED in switch is analyzed to automatically generate static multicast table. A test case of static multicast automatic generation with 220 k V typical intervals is developed. It is demonstrated by the test that the method can automatically generate static multicast in intelligent substation, and the minimum granularity determines the flow direction; beside, the method can improve field work efficiency and is practical.
