摘　　要：变电站是铁路建设的基础,二者关系密切,随着铁路的发展,变电站的接地网也越来越复杂,很容易发生故障,传统的变电站接地网故障诊断方法诊断速度慢,诊断缺乏准确性,因此需要基于Petri网技术设计新的变电站接地网故障实时诊断方法。首先采集了变电站接地网的故障信息,然后计算了变电站接地网故障电流冲击参数。最后基于Petri网技术分析故障诊断灵敏度,实现变电站接地网的故障诊断。实验结果表明,设计的故障实时诊断方法可以高效地诊断出接地网的故障,且具有较高的准确性。Substation is the foundation of railway construction,and there is a close relationship between them.With the development of railway,the grounding grid of substation is becoming more and more complex and prone to faults.The traditional fault diagnosis methods of substation grounding grid are slow and lack of accuracy,so it is necessary to design a new real-time fault diagnosis method of substation grounding grid based on Petri net technology,Firstly,the fault information of substation grounding grid is collected,and then the fault current impulse parameters of substation grounding grid are calculated.Finally,the sensitivity of fault diagnosis is analyzed based on Petri net technology to realize the fault diagnosis of substation grounding grid.The experimental results show that the designed fault real-time diagnosis method can effectively diagnose the grounding grid fault,and has high accuracy.
