智能配电网EPON通信技术的应用分析

Application Analysis of EPON Communication Technology in Smart Distribution Networks

高速、双向、实时的通信网络是配电自动化系统稳定运行的基础,以太网无源光网络(EPON)技术的高带宽、无源分光和长传输距离能适应配电网接入条件复杂的现状。在分析配电网通信系统现状以及EPON技术特点的基础上,结合配电自动化系统对通信网络设计和建设的要求,给出配电自动化通信系统的典型建设模式,指出采用EPON两级均匀分光模式组网的优势。为满足未来智能配用电业务对通信网络需求,讨论了EPON技术在互通性、网络共享、IEC 61850标准以及多通信技术互联等领域的应用展望。

High speed,bidirectional,real-time communication network is the basis of stable operation of a distribution automation system.EPON technology has advantages of high bandwidth,passive optical network and long transmission distance to adapt the complex conditions of the distribution network.Based on the analysis of the current situation of communication for distribution system,technical features of EPON and the requirements of the distribution automation system for the communication network,a typical construction model of distribution automation communication system is presented,and the advantage of adopting the two level uniform splitters as the construction mode of EPON system is pointed out.In order to meet the requirement of future smart power distribution and utilization businesses for communication network,the prospects of EPON technology application in interoperability,network share,IEC 61850 and heterogeneous network interconnection are discussed.
