基于OPNET的智能变电站通信网络仿真建模与性能分析

OPNET-based Simulation Modeling and Performance Analysis of Communication Network in Intelligent Substations

智能变电站的自动化程度与其通信网络的性能密切相关,良好的网络性能是其实现信息主动分析、智能调节、协同互动等高级应用的前提。为此,对智能变电站中的数据特征与通信网络性能进行了深入研究。首先,对智能变电站的数据特征进行了分析和建模;而后在OPNET中实现了对MMS协议的自定义搭建;最后,对一个典型结构的智能变电站通信网络进行了建模,仿真和分析结果验证了所提仿真建模方法的有效性。

The automaticity of an intelligent substation is bound up with the performance of its communication network. The realization of advanced applications such as active analysis of information, self-regulation, coordination interaction relies on a well-performed communication network. Therefore, it is urgently required to conduct an in-depth study on data characteristics and the performance of communication network in intelligent substations. Firstly, the characteristics of data in intelligent substations are analyzed and modeled. Then, the manufacturing message specification（MMS） is built up in optimized network engineering tools（OPNET）. Finally, some simulations are carried out based on a classical communication network in an intelligent substation. The simulation and analysis results show the effectiveness of the proposed simulation and modeling method.
