摘　　要：对变电站主要通信服务分类研究,根据服务要求和报文特点,通过变电站虚拟局域网的架构设计防范网络风暴的发生。采用通信报文的流量控制和报文过滤技术减少风暴出现后对运行保护的影响。以纵联差动保护为例,变电站网络风暴检测系统验证了采用上述措施后在注入不同风暴流量下,SV和GOOSE报文服务可不受影响。According to the investigation of classification of main substation communication services,as well as the service requirements and the message features,the virtual LAN architecture for substation is designed to prevent the network storms. It adopts message flow control and message filtering technique to reduce the impact to the service protection when a storm appears. In longitudinal differential protection,for example,the substation network storm detection system demonstrates that when the above-mentioned measures are adopted SV and GOOSE message services will not be affected upon different storm flows.
