摘　　要：中低压配电网智能化是实现智能电网发展的重要瓶颈。文章针对智能配电网组网方案的可能形式构建了通信网络,设计出基于以太无源光网络(EPON)的信息网络传输架构,对传输过程中可能出现的通信时延和阻塞现象进行了仿真和分析,提出了解决方案。文章特别介绍了退避算法的改进,总结出智能配电网的组成形式和通信架构,并解决时延和阻塞现象,对我国电力事业的发展具有重大意义。The intelligence of medium and low voltage distribution network is an important bottleneck to the development of smart grid. This paper builds communication network for the probable form of smart distribution network, and designs a transmission structure of information network based on EPON （Ethernet Passive Optical Network）. It simulates and analyzes the communication delay and congestion, which may occur in the process of transmission, proposes the solutions of this problem. Finally, this paper concludes that the composition form and communication structure of smart distribution network, and the solving of delay and back offhave an great significance to China＇s power industry.
