智能变电站通信网络中高可用性无缝环网的运用

摘要

This paper expounds the intelligent substation and high reliability of IEC 62439 seamless ring (HSR)the basic status quo. Sub-station based on functional requirements and data flow, this paper analyzes the HSR network USES the principle and realization of VLAN in HSR network technology, using network redundancy, improve system security, reduce the amount of switches and boost substation network per-formance.%本文阐述了智能变电站和IEC62439中的高可用性无缝环网（HSR）的基本现状。依据变电站功能需求及数据流向，分析了HSR网络的采用原则及HSR网络中实现VLAN技术，利用网络冗余提高系统安全性，减少交换机数量并提升变电站网络性能。
