摘要(Abstract):
根据IEC61850标准,归纳分析了数字化变电站内的各种典型数据流,运用明确的数学模型对其进行了详细描述,最终得出各类报文的数据包生成图。以IEC 61850-5规定的D2-1典型变电站为例,对其中存在的各种数据流及其流量大小进行了详细说明;利用OPNET仿真软件,应用优先级标签技术,对基于虚拟局域网(virtual local area network,VLAN)的集成型变电站综合通信网络进行了仿真分析,进一步研究了变电站通信网络中VLAN的配置方法和原则,对有无VLAN的星型网络进行了对比研究。结果表明,VLAN技术可以较好地解决变电站中的网络资源竞争以及部分安全性问题。
