智能变电站IEEE1588以太网交换机故障案例复现测试及分析

为解决和预防智能变电站IEEE1588交换机在特定网络环境下运行可能会带来的潜在风险,针对智能变电站IEEE1588交换机运行的网络拓扑结构,给出了一种逐级隔离的故障分析方法。通过某智能变电站IEEE1588交换机的具体应用故障案例,对故障现象进行离线的复现与分析,总结出了故障产生原因并给出了整改建议。案例分析表明,通过逐级隔离的分析方法,可以快速地进行故障分析和定位,通过对故障现象的复现,可有效地进行故障原因分析,从而得出相应的解决方案。

Fault case analysis of IEEE1588 switch application in smart substation

According to the network structure of IEEE1588 switch operation, a kind of fault analysis method of isolated by level is provided to resolve and prevent the potential risks of IEEE1588 switch operated under special network environment. Via a specific fault case of IEEE1588 switch application in smart substation somewhere, rebuilding and analyzing the fault phenomenon off line, the fault reason is concluded and amendment advices are recommended. This fault case analysis indicates that we can locate and analyze fault rapidly via the method of isolated by level, after rebuilding the fault phenomenon, we can analyze the fault reason effectively and then get the corresponding solution.
