| 摘 要： | 目前智能变电站过程层网络一般采用星形以太网，重要设备间的通信需构建双星形以太网以确保可靠性，成本很高。文章提出一种基于高可靠无缝冗余环（HSR）技术的变电站过程层网络构架。相比工业以太网交换机组网方式，变电站内HSR通信结构不仅可实现站内二次设备间的数据传输，满足变电站过程层网络功能要求，同时具有高可靠性、低成本的特点。

| Abstract: | Generally the existing process layer network in intelligent substations is an Ethernet with star topology, and the communication links among important devices commonly are built by double star topology in order to ensure high reliability, which has a high cost. This paper proposes a method that applies the high availability seamless redundancy （HSR） technology to construct the process layer network in substations. Comparing with the networking scheme using the industrial Ethernet switch, HSR structure can not only enable data transfer among secondary devices in substations to meet the functional requirements of the process layer network, but also have characteristics of high reliability and low cost. |
