摘　　要：设计了网络分析与故障录波一体化系统。系统由5个模块组成:报文采集、解析模块通过以太网嗅探技术捕获数据包,并从中提取录波模拟量和开关量发送给故障录波模块;报文监测、记录模块对网络报文进行在线实时监测和无损记录,对变电站网络通信状态进行在线实时监测和评估;故障录波模块完成录波启动和波形记录;高精度时钟模块为各模块提供精准的绝对时标;分析站模块负责装置建模、各个模块的配置与管理、故障和报文分析以及对外通信。报文采集解析、故障启动录波、报文监测记录均采用独立CPU进行处理,保证了网络报文记录和故障录波在硬件上的独立性;报文采集和录波数据的同步处理采用同一网口的数据源,使用同一时标,在关联分析中可以通过同一时刻点对录波数据与报文数据进行分析。An integrated network analysis and fault recording system consisting of five modules is designed. The message collection and analysis module applies the Ethernet sniff technology to capture data packets, extracts the analog and binary variables from the data packets and sends them to the fault recording module. The message monitoring and recording module online monitors and records the network messages in real time ,as well as monitors and evaluates the communication states of station. The fault recording module initiates the fault recording and records the fault waves. The clock module supplies accurate time for other modules and the analysis module is responsible for the configuration and management of device and modules,the analysis of fault and message and the communication to outside. Each module has independent CPU to ensure the hardware independence of fault recording and message recording. Because the message collection and fault recording apply the same data source from the same network port and use the same time scale,the relevancy analysis can be carried out with the fault recording data and message data on the same time.
