摘　　要：将Petri网理论用于船舶电力系统故障诊断中,提出了一种改进的Petri网故障诊断模型。在基本Petri网诊断模型的基础上引入模糊推理规则形成模糊Petri网,说明了该方法的模型构建、推理过程及解析方法的表示。利用该方法对船舶电力系统进行故障诊断使推理过程简洁、诊断快速、诊断结果也更科学有效。In this paper, it is presented that the application of Petri net theory in ship power system fault diagnosis. And it is proposed that an improved Petri net based fault diagnosis model. Fuzzy inference rule is introduced by basing on the basic Petri net diagnosis model to be fuzzy Petri net. The article illustrates the construction method, reasoning process and analytical expression of fuzzy Petri net. By using this method, ship power system fault diagnosis is simple and quick, and the result is more effective.
