基于Opnet支持IEC60870-5协议的配电网EPON通信仿真

摘要

介绍了一种支持IEC 60870-5-101和IEC 60870-5-104协议的智能配电网EPON通信系统。运用IEC 60870-5协议搭建系统模型，给出了某供电系统一条供电线路的拓扑结构，利用Opnet软件进行仿真分析，结果表明，该系统最大端到端延迟小于10 ms，业务吞吐量可以达到37.5 Mbit/s，满足了实际的通信要求。%Introduction was made to a kind of EPON communication system of intelligent distribution network supporting IEC 60870-5-104and IEC 60870-5-101protocols. The IEC 60870-5 protocol was used to construct a system model. This paper gave the topological structure of the supply line of certain power supply system, simulating the system with the software Opnet. The simulation results show that the business throughput is up to 37.5 Mbit/s and the maximum end to end delay is less than 10 ms, which meets the actual communication requirements.
