基于OPNET的电力通信EPON仿真建模研究

摘要

成本低廉、易维护等特点使得EPON(以太无源光网络)成为智能电网配用电通信的首选,而在先期网络规划、后期网络性能等参数的综合评估等方面尚缺乏有效的理论分析方法。因此在研究EPON网络的基础上,利用OPNET分别构建了EPON的OLT、POS、ONU网元模型,并针对在电力通信中的应用,完成了电力通信业务的建模,构建了面向电力通信的EPON仿真研究平台。对常见电力通信EPON组网方式进行了实验,并对实验结果进行了分析。实验结果表明,所搭建的电力EPON仿真研究平台可对电力通信业务性能进行测试与分析,EPON系统完全符合电力通信业务的传输要求。%The low cost and easy maintenance of Ethernet Passive Optical Network also called EPON,makes it be the first choice in elec-trical communications of the smart grid. While there are lack of effective theoretical analysis from the perspective of parameters evaluation in early network planning and late network performance. For the application of electric power communication,consequently,the traffic of electric power communication is raised on the basis of EPON network and further simulation platform is constructed by using the OPNET network simulation software. Some common network structures on this platform are simulated and analysis of the results is made corre-spondingly. The result shows that the built EPON simulation and research platform can test and analyze the performance of electric com-munication traffic,and EPON can absolutely meet the requirements of the electric communication traffic.
