摘　　要：研究了智能牵引变电站网络架构及组网方式,将智能牵引变电站划分为"三层两网"结构,给出站控层网络和过程层网络的2种不同网络架构方案。结合VX接线的牵引变电站间隔分布,讨论了网络架构中的重要组成部分之一网络冗余方案,对比国内外实现方案,给出了一种含并行冗余协议(PRP)的站控层双环网拓扑结构和含PRP冗余协议的过程层双星型拓扑结构,优化了常用的冗余方案。The network architecture and networking mode of smart traction substation are researched. The smart sub- station is divided into ＂three-layers and two-net＂ structure. Two different network architectures of station level and process network are given. The network redundancy scheme, one of the important components of the network archi- tecture, is discussed combined with the VX wiring traction. In contrast to the implementation scheme at home and abroad,the double-ring network topology with PRP （Paratlel Redundancy Protocol） in station level and the double- star topology with PRP in process level are given, and the commonly used redundancy scheme is optimized
