摘要
提出一种面向AgentPetri网改进型模型,给出了该Petri网模型的一般性结构、网络的形式化描述和结构特性属性的定义及其定理,将Agent的自治性、协作性、容错性在模型中予以具体的表达。针对一种广域后备保护算法为其建立较精确的面向AgentPetri网模型,对其进行L3-活性和多Agent动态行为跟踪有效性的分析。通过算例分析了电力系统发生故障时Petri网的推理过程,验证了所构建的多AgentPetri网模型的正确性和有效性,能较好地构造广域后备保护分布式系统的内部结构和活动,有效地跟踪系统的动态行为,使得广域后备保护系统的设计更加系统化。
According to the characteristics of distributed cooperating and parallel working in wide-area backup protection （WABP） multi-agent system, an improved agent-oriented Petri net （AOPN） is proposed to modeling the dynamic behaviors of multi-agent system. The general architecture, the definitions of the formalization, structural properties and theorems are given to describe the features of the suggested novel Petri net model. The characters of autonomy, corporation, concurrency and robustness of agent are embodied in the Petri net. A Petri net model for a kind of WABP algorithm is constructed, together with the analysis of L3-1iveness, consistency and effectiveness of capturing dynamic behaviors. The reasoning results of three s^imples Can illustrate that Petri net model for WABP multi-agent system is correct and the tracking of dynamic behaviors of system is ＇effective. AOPN can clearly describe internal activities and interactions among WABP agents, analyze and track dynamic behaviors of system. As a result, it improves the systematization and specification of WABP agent design.
