摘　　要：智能变电站过程层组网通信质量决定了站内继电保护及自动化等二次设备的安全、稳定和可靠运行。目前主流使用虚拟局域网(Virtual Local Area Network,以下称VLAN)与静态组播技术对智能变电站内大量二次设备进行通信子网划分,以提高组网通信质量与安全水平。但是,高度安全的网络结构意味着维护改造更加困难,实际组网配置方案的优劣还受到复杂的现场情况与其他人为因素影响。本文将结合在运智能变电站实际案例,分析讨论VLAN和静态组播两种技术在过程层组网中的应用,为智能变电站过程层网络配置优化方向提供参考。The communication quality of process layer network of smart substation determines the safety,stability and reliable operation of secondary equipment such as relay protection and automation in the station.At present,the mainstream uses Virtual Local Area Network(VLAN)and static multicast technology to divide the communication subnets of a large number of secondary devices in smart substations to improve the communication quality and security level of the Network.However,a highly secure network structure makes maintenance and renovation more difficult.The actual network configuration scheme is also affected by complex field conditions and other human factors.This paper will analyze and discuss the application of VLAN and static multicast technology in process layer networking based on the actual case of Yun-smart substation,so as to provide a reference for the optimization direction of process layer network configuration in smart substation.
