基于IEC 61850的智能变电站通信网络的实时性分析

摘要

The performance of the communication network -the information exchange channel of smart substations -has a direct effect on reliable realization of their related functions.Based on the IEC 61850 communication protocol,this paper introduced smart substations'requirement on the real-time property of the communication network.The D2-1 medium-sized distribution substation was selected as a research case to establish a complete communication network model of the smart substation.OPNET simulation software was used to make a comparative analysis on the real-time property of three communication network topologies from the perspective of different messages.Furthermore,a network optimization scheme was proposed on the basis of simulation results,thus effectively improving the real-time property of the communication network of the smart substation.%通信网络作为智能变电站的信息交互渠道,其性能优劣直接影响了智能变电站相关功能的可靠实现.基于IEC 61850通信规约,介绍了智能变电站对于通信网络的实时性要求.以D2-1型中等配电变电站作为研究案例,建立了完整的智能变电站通信网络模型,利用OPNET仿真软件,从不同报文的角度分析对比了三种通信网络拓扑的实时性.基于仿真结果提出了网络优化方案,有效提升了智能变电站的通信网络实时性.
