摘要
随着变电站智能化水平的不断提高,智能变电站一体化信息技术的需求也越来越受到关注.首先介绍了现行智能变电站的通用结构,针对其信息共享不充分的问题提出了"四网合一"的方案.然后基于端对端延时特性分析对其可能的不同网络拓扑进行建模,并对不同数据包大小下各种拓扑的延时和相同数据包大小下不同拓扑的延时给出仿真结果.最后通过对仿真结果的讨论分析并综合实时性和可靠性考虑,对智能变电站"四网合一"方案做出选择.
With the growing increase of the level of intelligence in substation,the demand about integrated information technology of smart substation also get more and more concern.At first,the general hierarchy of smart substation is introduced,and a thought of four-in-one network is proposed in the case of its insufficiency about information sharing.Secondly,based on the analysis of end-to-end delay characteristics,the paper models possible different types of network topologies,the simulation results about the delay of different topologies among different data packet sizes and same data packet size among different topologies are also given.Finally,after the discussion and analysis of simulation results,considering real-time and reliability,the paper makes a choice about the scheme of smart substation four-in-one network.
