| 摘 要： | 利用动态建模技术对IEC 61850-5中D2-1型变电站层次化建模。应用准确的数学模型对变电站内智能电子设备间传输的综合数据流进行全面时域建模。在基于端口的虚拟局域网(Virtual Local Area Network,VLAN)划分基础上,运用优先级标签技术划分站内数据流传输优先级,分别对星型,环形拓扑结构变电站自动系统进行有无VLAN的跨间隔,跨层研究。OPNET仿真结果表明,采用星型,环形组网与VLAN技术,可以有效改善变电站通信网络实时性,较好地抑制广播信息泛滥问题。

| Abstract: | The OPNET Modeler is used for hierarchical model of the D2-1 type substation specified by IEC 61850-5 standard.An accurate mathematical model is applied for modeling of the typical data flow which is transmitted between smart electronic devices in the smart substation.Based on virtual local area network (VLAN) port division and priority tag technology,comparative study on star and ring topology network to judge whether it has VLAN or not.The cross bay division and cross layer division are carried out.The simulation results indicate that the substation communication network,which adopts star and ring topology,VLAN can improve the real-time characteristic of substation communication network and suppress the spread of broadcast information. |
