Research on Communication Network for Five-prevention System in Bay Level Based on Optimized Network

随着智能电网的逐步发展,利用共网技术满足智能变电站安全操作、经济运行已成为未来的发展方向。提出了优化的网络拓扑结构,将间隔层五防系统嵌入新型组网当中,依据新型拓扑结构搭建智能变电站仿真模型,同时配置通用属性注册协议组播注册协议(GMRP),并利用虚拟局域网(VLAN)技术对组网进行划分。最后通过OPNET软件仿真验证了五防信息能够在优化组网中稳定传输。

With the development of smart grid, co-network technology is used to realize the safe operation and economic operation of intelligent substation in future. The paper proposes an optimized network topology , imbeds a five-prevention system in bay level into the topology, and establishes the intelligent substation simulation model according to the new topology. Meanwhile, generic attribute registration protocol （GARP） based multieast registration protocol （GMRP） is configured, and virtual network （VLAN） is adopted to partition the co-network. Finally, the simulation results using OPNET show that the stable transmission of five-prevention information can be realized in the optimized network.
