基于信息流监测与解析的遥控缺陷诊断技术应用

为了提高遥控缺陷原因分析的准确性，针对实际运行中遥控失败所呈现的系统性、过程性以及偶发性特征，提出基于信息流监测与报文解析技术的诊断方法。通过全程监测、记录变电站监控系统以及远动环节数据交互的信息流，捕捉遥控异常过程中以太网传输层与应用层通信报文中的关键信息，分析定位遥控失败原因。该方法解决了遥控过程环节多、技术复杂、故障难以重现等带来的困惑，全过程、全覆盖的信息流监测记录与报文解析，使得遥控失败踪迹展露无遗，为缺陷原因准确诊断与处理方案制定提供翔实技术依据。应用经验表明，基于信息流监测与报文解析的诊断方法效果好，尤其对偶发性的遥控缺陷分析优势明显，值得推广应用。

Application of remote control defect diagnosis technology based on information flow monitoring and analysis

A diagnosis method is proposed in order to improve the accuracy of the analysis concerning remote control defects. The method is based on the monitoring of information flow and the parsing techniques of message, focusing on the systematic, procedural, accidental characteristics in the actual remote control operation. Through the monitoring system of substations and the data of remote information flow interactions, the key information of Ethernet transmission layer and application layer is captured in the abnormal remote control process, followed by the analysis of positioning control failure. The method solves the problems of remote control connections, complicated technology and difficulties in reproducing the faults. The whole process and full coverage of monitoring records and parsing message on information flow find the trace of the remote control failure, which also provide the technical basis for accurate defect diagnosis and the treatment plans. It is proved that the diagnosis method based on the monitoring of information flow and the analysis of the message is effective. Especially, it has a great advantage on the analysis of remote control defects, which is worth popularizing.
