摘　　要：智能变电站通信网络化在增强设备间的兼容性和互操作性的同时带来了网络设备故障、网络拓扑错误等一系列棘手问题。为了解决智能变电站过程层网络拓扑错误问题,提出使用网络流量的变化为判断特征的过程层网络拓扑错误辨识方法。首先给出整定网络正常运行时的网络流量值方法,然后通过分析网络拓扑故障场景中网络流量与整定值的相对变化结果,验证基于转移流量法的过程层网络拓扑错误辨识的正确性。该方法辨识准确度高,步骤简单,具有良好的工程应用前景。That communication of smart substation is networked enhances device compatibility and interoperability. Meanwhile, it brings a series of troublesome issues, including network equipment failures, network topology error. In order to solve the topology error problem of smart substation process-level network, this paper proposes a network topology error identification method using changes in network traffic as judgment characteristics. Firstly, the paper provides the method to calculate a setting value of network traffic during normal operation of the network. And then, the paper analyzes result of network traffic change between network fault scene and normal scene. From the analysis, the paper verifies the validity of the identification method. The identification method has high accuracy, simple procedure and a good prospect of engineering.
