网络报文分析系统在故障分析中的新应用——基于网络报文数据融合的两种故障分析手段

New Application of Network Message Analysis System in Fault Analysis:Two Fault Analysis Methods Based on Network Message Data Fusion

目前的网络报文分析系统主要是实现网络报文的异常分析以及对网络异常的实时监测。局限于单网络报文分析系统,且一般应用于单间隔一次设备的故障分析。介绍两种通过多网络报文分析系统的数据融合实现跨间隔主变设备的故障分析以及跨变电站的线路的故障分析方法,并详细描述了两种故障分析方法的工作流程、运行方式,为主变故障事后分析和线路故障分析提供了一种新的分析手段和方法,为电力系统事故后分析提供了参考依据。

The current network message analysis system is mainly used to realize the network message anomaly analysis and real-time monitoring of network anomalies,which is confined to primary equipment fault analysis with a single interval. This paper introduces two methods for trans-interval transformer equipment fault analysis and for trans-substation line fault analysis respectively accomplished through data fusion of multiple network message analysis system,and describes their working process and operation mode. They are new methods for postanalysis of main transformer and line faults,and provide some reference for the fault analysis of power system after the accident.
