为解决智能变电站过程层数据共享传输过程中出现的网络流量过大引起冲突或广播风暴的问题,分析研究网络报文流量的大小和过程层交换机网络延时,提出采用优先级和VLAN分级流量控制技术方案,并结合鲍店矿智能变电站实际情况进行VLAN逻辑划分,在应用中取得显著效果。 In order to solve the problem of conflict or broadcast storm due to excessive network traffic during the process of data transmission of process layer in intelligent substation, the size of network packet flow and the network delay of process layer switch are analyzed and studied, and the priority and VLAN hierarchical flow control Technical program, and combined with the actual situation of Bao Dian mine intelligent substation VLAN logic division, achieved significant results in the application.
