摘要
现今智能电网相关技术快速发展,文中提出了一种基于Petri网(PN)的智能电网故障识别及定位的方法,该方法既能检测数据传输故障,又能识别含高渗透率DG的配电系统中的故障。介绍了关于PN模型的基础理论,通过对单保护系统和电流检测器的多个PN模型进行系统组合,实现了配电网系统PN模型的设计。通过示例详细地说明了故障过程与故障检测方法,进行了算例分析,结果证明了所提方法可大幅降低相关数据分析的复杂性。
With the rapid development of smart grid technologies,this paper proposes a fault diagnosis and location method of smart grid based on Petri net theory which can not only detect data transmission faults,but also identify the faults in the distribution system with high permeability distribution generations.The basic theory of Petri nets model is introduced at first.The PN model of distribution network system is designed through combination of multiple PN models of single protection system and current detector,and the fault process and fault detection method are explained in detail through an example.Finally,two case studies are analyzed and the results show that the proposed method can significantly reduce the complexity of relevant data analysis.
