摘　　要：为满足新型电力系统末端通信接入越来越高的大容量和可靠性传输要求,提出一种新颖的对环型波分复用电力通信光接入网架构。通过全新设计的切换模块与交换模块,充分利用各类光器件特性,对中心端局和远端节点分别进行重构。所提设计使得网络兼具了规模化和模块化的特性,同时采用对环型架构搭建,重新设计了光信号在网络中的传输方式,根据在不同运行模式下的传输方式切换使得整体网络不仅具备高可靠性,还能实现波长的多重复用。通过建模分析与仿真测试,上述功能及特性均得到验证,网络具备良好的传输性能。To meet higher capacity and reliability transmission requirements on new type power system,this paper proposes a novel modularized double-ring wavelength-division multiplexer electric power communication access network.By originally designing the switch and the exchange modules and fully using different characteristics of the components,the central office and the remote nodes are reconstructed respectively.The network possesses both features of modularity and scale.By establishing the double-ring topology,it redesigns the transmission mode of optical signals in the network.The switch of the transmission mode under different operation ways makes the network not only have high reliability,but also support wavelength reuse.Simulation and modeling analysis also verify the mentioned functions and characteristics of the network as well as the good performance.
