GPON在智能配电网络中的应用及其带宽分配

Application of GPON in distribution network and corresponding bandwidth allocation

从智能配电网络的承载系统出发,研究了基于千兆位无源光网络(GPON)的智能配电监测网络架构及标准体系。结合目前的配电自动化系统分析了配电采集终端的业务特性,并通过附带业务解析功能的带宽分配方案,实现了多种业务等级的配电业务接入。此外,针对配网终端数量众多的特点,设计了分级业务调度的方案,通过光网络单元(ONU)间与ONU内部数据调度相结合的方式,实现不同类型的业务接入控制,以适应未来大规模智能配网的新业务应用。

The bearing system of intelligent power distribution networks is paid great attention, and a monitoring network architecture based on the standard gigabit-capable passive optical netwark （GPON） system is presented. An acquisi- tion device in distribution automation systems is analyzed together with the associated service characteristics, mean- while, a service oriented bandwidth allocation scheme is presented to achieve a variety of service-level distribution service access. In addition, according to the large amount of distribution network terminals, differential service scheduling programs are designed through a combination of inter-ONU （ optical network unit） and internal-ONU scheduling, and different types of service access controlling are investigated to adapt to future large-scale smart dis- tribution network applications.
