基于静态组播搜索的电力交换机检修技术研究
|
摘要
分析了电力交换机静态组播技术在智能变电站数据采样通信中的应用,阐述了静态组播设置有误导致网络风暴或保护装置采样数据异常的现象,不当的组播机制会导致保护装置产生误动或拒动结果。针对智能变电站电力交换机缺乏检测手段的现象,介绍了一种基于静态组播搜索模式的电力交换机检修系统。该系统对交换机一个端口动态地发送不同MAC地址的组播流,同时回采并统计交换机其他端口组播流类别,利用一口发多口收的闭环测试方法来搜索交换机所有端口的MAC地址,并形成电力交换机各端口静态组播配置表。实验证明,闭环模式下组播搜索的方法能够实现电力交换机MAC地址表的测试,具有很好的实用性。
This paper analyzes the application of static multicast technology in data sampling communication of intelligent substation, describes the phenomenon of abnormal data sampling caused by network storm or protection device caused by static multicast setting error, and states that improper multicast mechanism can cause the protection device to produce maloperation or rejection results. A power switch maintenance system based on static multicast search mode is introduced in view of the lack of detection means in intelligent substation power switch. The system dynamically sends multicast streams with different MAC addresses to one port of the switch, collects and counts the multicast streams of other ports of the switch, searches the MAC addresses of all ports of the switch by using a closed loop test method of one-port multi-port receiving, and forms a static multicast configuration table for each port of the power switch. Experimental results show that the method of multicast search in closed-loop mode can test the MAC address table of power switch, thus it has good practicability.
