网络风暴对智能变电站设备和系统的影响研究

Research on the influence of network storm on equipment and system of intelligent substation

智能变电站网络风暴直接影响着智能二次设备的正常通讯。通过分析智能变电站网络风暴的特点和产生原因,对网络风暴对站控层设备和系统、过程层设备的影响进行了测试,发现了网络流量、字节、报文类型等是网络风暴影响各类二次设备通讯的原因之一。针对网络风暴的影响,提出了在工程实际应用中抑制网络风暴的方法。

Intelligent substation network storm directly affects the normal communication of intelligent secondary equipment.Based on the analysis of the characteristics and causes of intelligent substation network storm,the influence of network storm on station control layer equipment,system and process layer equipment was tested,it is found network traffic,byte,message type and so on are one of reasons that network storm affects all kinds of secondary equipment communication.Aiming at the influence of network storm,six methods of restraining network storm in practical engineering application are put forward.
