| 摘 要： | 针对一500 kV变电站长期出现的站内测控装置不定期报通信中断和五防校验超时信号,导致操作失败的现象,通过截取报文分析,发现由于存在大量的UDP心跳报文和联锁报文,造成广播网络风暴引起通信中断,通过对网络层交换机划分VLAN,隔离广播流量,成功解决了该问题。

| Abstract: | The operation failure problem caused by random communication interruption of measurement and control equipment and the overtime of misoperation logic verification in a 500kV substation is analyzed by intercepting messages.It is founded that the communication interruption is caused by broadcast storm which is caused by a large amount of UDP messages and interlocking messages.The problem is solved by dividing VLAN of switch to isolate broadcast traffic. |
