通信在线监视系统在数字化变电站的应用

Application of Online Communication Monitoring System in Digital Substations

数字化变电站中,传统的二次回路被过程层网络所取代,同时,网络化的二次设备增加了对接收链路的监视功能,接收方可以根据密集发送的数据和较为稀疏发送的数据的状态对接收的链路进行监视,并在异常情况下发出告警信息。数字化变电站通信在线监视系统是数字化变电站通信监视设备,可对网络通信状态进行通信在线监视,并对网络通信故障及隐患进行告警,有利于及时发现故障点并排查故障;同时能够对网络通信信息进行无损失全记录,以便于重现通信过程及故障。

In digital substations, traditional secondary circuits are replaced by process-level networks. Secondary network equipments enhance the monitoring of receiving link. Receiver can monitor the link based on the conditions of intensively-sending data and sparsely-sending data, and alert information can be sent out where unusual cases occur. Online communication monitoring system is a communication monitoring equipment in digital substations, which can monitor the network communication conditions online, and can alert communication faults and potential dangers. In this way, faults can be discovered and removed in time. Meanwhile, lossless full record of network communication information can repeat the communication process and faults.
