摘　　要：针对智能变电站采用传统"三层两网"网络架构时存在的结构复杂、设备成本高,受间隔层设备隔离和过程层网络覆盖范围有限因素的制约,数据在间隔之间以及过程层直达站控层的传递不够灵活的问题,对变电站数据类型、网络构架以及组网设备等方面进行了研究,提出了一种采用无源光传感网络技术构建的"两层一网"的智能变电站架构。利用无源光纤网络(passive optical network,PON)组建了全站智能化网络,并采用分组交换、并行网络、逻辑GOOSE/SV/MMS子网等面向连接技术替代了现有面向对象的以太网构建技术,完成了全站网络的整合。变电站中任意两个设备通过统一网络可以直接实现通信,实现间隔层设备与过程层设备的整合。研究结果表明,"两层一网"的架构具有结构简单、组网设备少、抗干扰能力强、稳定性好的特点。Aiming at adopting the traditional＂three layer two network＂architecture,the intelligent sabstation was limited by high equipment cost,the interlayer device isolation and process level network coverage for substation data type,network architecture and network equipment and other aspects of the study,a intelligent substation framework constructed was put forward by the network technology of passive optical sensing double layers network. Using the passive optical network（ PON） form the station intelligent network,and adopting the packet switching,parallel network,logical GOOSE / SV / MMS sub-networks,connection oriented technology to replace the existing object oriented Ethernet construction technology,the station network was integrated. Any two devices of the substation could realize the communication directly through a unified network,and the integration of spacer device and process level device. The results indicate that double layers network architecture has the characteristics of simple structure,less equipment,strong anti-interference ability and good stability.
