摘　　要：船舶电力系统应保证供电连续性,尽量缩短电力系统故障时间.在分析船舶电力系统自身特点的基础上引入Pe-tri网技术,充分利用Petri网技术对电力系统故障进行建模的快速性对船舶电力系统故障进行诊断.研究利用Petri网技术对船舶电力系统进行故障仿真,包括模型建立、故障诊断以及对不确定信号的诊断与排除.诊断结论充分验证了Petri网技术的有效性和快速性,利用该方法能够帮助快速准确地判断事故,及时排除故障.Marine electrical power systems have to provide a continuous supply of electricity. At the same time, they must shorten unavoidable power outages as much as possible. After a detailed analysis on the unique characteristics of marine electrical power systems, we made use of Petri net technology to determine their faults. The paper focused on best methods for modeling, fault diagnosis, and diagnosis and removal of uncertain signals. The diagnosis results in the study verified the effectiveness and speediness of the Petri net technique. So it can locate the faults accurately and rapidly, making it possible to deal with them in a timely way.
