Research and Analysis of Communication Fault in Intelligent Substation

针对智能变电站通信系统故障问题,从实际出发,对智能变电站常见的通信故障问题进行分析,结合数据统计及理论分析提出解决网络风暴、数据缓存溢出的方法。将所提方法应用于智能变电站后,对变电站通信系统进行调试及试验,试验结果表明所提出的网络风暴抑制方法及加装“软件狗”程序方法可有效减少瞬时网络流量较大和交换机数据缓存溢出问题导致的通信系统故障,对变电站的安全高效运行具有重要的作用。

Aiming at the problem of communication system failure in intelligent substations,the common communication fault problems of intelligent substations are analyzed from the actual point of view.Combined with data statistics and theoretical analysis,a method to solve the network storm and data buffer overflow is proposed.After applying the proposed method to the intelligent substation,the substation communication system is debugged and tested.The experimental results show that the proposed network storm suppression method and the installation of"dongle"program can effectively reduce the communication system failure caused by large instantaneous network traffic and switch data buffer overflow,and play an important role in the safe and efficient operation of substation.
