摘　　要：为了及时发现无人值守变电站的通信网络异常现象,降低通信异常给变电站运行带来的影响,优化设计无人值守变电站通信异常智能告警方法。考虑变电站通信网络的连接结构与通信原理,智能捕获无人值守变电站通信数据包,通过通信数据包特征的提取与匹配,判定当前变电站通信网络的异常状态,执行相应的告警程序,完成无人值守变电站通信异常的智能告警工作。通过与传统告警方法的对比可知,优化设计告警方法的误警率降低了8.6%,同时有效降低了漏警率。In order to find the communication network anomaly of unattended substation in time and reduce the impact of communication anomaly on substation operation,the intelligent alarm method for communication anomaly of unattended substation is optimized.Considering the connection structure and communication principle of the substation communication network,it can intelligently capture the communication data packet of the unattended substation,determine the abnormal state of the current substation communication network through the extraction and matching of the characteristics of the communication data packet,execute the corresponding alarm program,and complete the intelligent alarm work of the communication abnormality of the unattended substation.Through the comparison with the traditional alarm method,the conclusion is drawn that the false alarm rate of the optimized design alarm method is reduced by 8.6%,and the missed alarm rate is effectively reduced.
