采用SV和GOOSE共口传输的过程层组网方案

为了解决智能变电站过程层组网中采用SV和GOOSE共口传输方式所面临的报文过滤问题,简述了智能变电站过程层网络组网方案,通过分析智能电子设备IED之间的报文流量特征和通信需求,探讨了限制SV和GOOSE两种多播报文的配置方案,从工程应用的角度提出了一种基于VLAN技术的组网方案:根据IEEE802.1Q标签区分SV和GOOSE报文,对两种报文采取不同的VLAN划分原则。搭建试验平台对该方案进行了测试和分析,结果表明:该方案具有减少终端IED接收网络压力、工程实施简单、数据流向清晰的优点。该方案对新一代智能变电站过程层组网具有参考意义。

Process-layer Networking Scheme Based on SV and GOOSE Common Port Transmission

To solve the message filtering problem in the process-layer networking of an intelligent substation using sampled value(SV)and generic object oriented substation event(GOOSE)common port transmission,the process-layer networking scheme of the intelligent substation was briefly described at first.Then,the configuration scheme of restricting multicast messages for SV and GOOSE were discussed by analyzing the characteristics of message flow and communication requirements among intelligent electronic devices(IEDs).A networking scheme based on virtual local area network(VLAN)was put forward from the perspective of engineering applications,in which SV and GOOSE messages were distinguished using different division principles according to IEEE 802.1Q tags.Tests and analyses of this scheme were carried out,indicating that it had advantages of lowering the network’s pressure in receiving data at terminal IEDs,simplifying the project implementation,and making the data flow clear.The proposed scheme has reference significance to the process-layer networking of new generation intelligent substations.
