基于OPNET的智能变电站通信建模与组网研究

Smart Substation Communication Modeling and Networking Based on OPNET

智能变电站通信组网方式决定了其通信性能,现阶段尚缺乏有效的智能变电站通信网络性能分析模型与手段,对此,基于OPNET软件平台搭建了适用于智能变电站网络性能分析的过程层、间隔层、站控层设备通信模型,并在此基础上,对智能变电站的组网方式开展研究。设置不同网络场景,通过对过程层网络与站控层网络分别组网方式以及采样值、通用面向对象的变电站事件、制造业信息规范网"三网合一"的方式进行仿真,获取不同组网方式的网络性能。仿真结果表明,两种组网方式均能适用于不同状态下的网络性能要求,能够应用于智能变电站的通信组网。

Communication networking of the smart substation decides its communication perfoof effectivemodels andmeans for the analysis of communication network performance of the smart substation at presen. Therefore, on the basis of OPNET platform, this paper builds communication models for the process laylevel device and station layer equipment , which are suitable for performance analysis for smart substation networking , and furthermore , this paper also studies the networking mode of the smart substation. By simulating different network scenes on respective network modes of the process layer network and station layer network as well as a tri-networksampled value , generic object oriented substation event and manufacturing message specification , so as to acquire network performance of different networking mode.. Simulation results indicate that the two networking modes can both apply to re-quirements for network performance under different states and communication networking of the smart substation.
