220kV泸定智能变电站过程层网络的优化

Optimization of Process-Level Network in Luding Intelligent Substation

220 kV泸定变电站是按照IEC 61850标准设计的智能变电站,智能变电站过程层网络的实时性、可靠性要求高。分析了智能变电站过程层网络的发布/订阅通信模型以及OSI模型第二层交换技术的特点,从网络拓扑结构、静态VLAN划分以及动态组播过滤技术对泸定变电站过程层网络进行优化,以完善和提高泸定变电站过程层网络的功能和性能。

Luding Substation was designed as an intelligent substation according to IEC 61850. Based on the high re- quirement for real-time communication and reliability in its process-level network, this paper analyses the process-lev- el network＇s characteristics of P/S model and switching technology in OSI layer-2, and optimizes the process-level network in terms of network topology, static VLAN division and dynamic multicast filtering technology, with a view to improving the process-level network function and performance.
