| 摘 要： | 变电站应用SCADA系统可以获得大量继电保护和断路器动作信息，然而这些信息可能是不完全不确定的，这限制了故障诊断的有效性和正确性。文章尝试使用模糊Petri网来处理SCADA系统获得的这些不确定信息，以期获得较好的并行处理性和容错性。在模糊Petri网的基本概念的基础上，阐述了搜索故障区域的方法，建立了故障诊断的模糊Petri网模型。运用文中所提出的方法进行了实例研究，仿真分析结果说明了方法的可行性。

Fuzzy Petri Net Based Fault Dignosis for Substation |
| |
| Abstract: | The substation can acquire plenty information of delay protection and switch using SCADA system. But these information can be uncertain or not completed, which may cause incorrect diagnose result. Since the problems involve some fuzzy and random information,a fuzzy reasoning approach based on fuzzy Petri nets is proposed. This paper gave a definition for fuzzy Petri nets and a method to find out the fault area. Also how to built a Petri net model is discussed in detail. At last, an example of substation fault diagnosis case is illustrated to show the application and feasibility of the proposed model and approach. |
