In accordance with characteristics of shipboard integrated power system, we use technique of Petri net to diagnose their faults. The Petri net models can represent the procedure of the fault processing directly and clearly. By using matrix operation, the reasoning calculation can meet the need of the rapidity of fault diagnosis. Results of the testing example prove that the approach proposed is correct and effective.%针对舰船综合电力系统的特点,利用Petri网技术对综合电力系统故障进行诊断.Petri网模型清晰直观,符合故障处理过程因果关系,其基于矩阵运算的推理计算能满足快速故障诊断的要求.算例测试结果表明了该方法的正确性和有效性.
