摘要
介绍了针对巨型起重船电力系统(large crane vessel's power system,LCVPS)实施故障模式影响分析(failure modes and effects analysis,FMEA)的具体方法,并按照系统级与设备级依次展开FMEA研究。分析了巨型起重船电力系统发电、配电、起重各功能模块及模块中实现功能的具体设备的潜在故障模式、发生故障的原因、故障对局部及全局的影响等。运用Matlab软件对巨型起重船电力系统建模及故障仿真分析,以获得定量的故障数据,以便采取有效措施尽快消除故障,提高系统的可靠性。
In this paper, the detailed method of implementing failure modes and effects analysis （FMEA） for the large crane vessel＇s power system （LCVPS） is introduced, and FMEA is developed from the level of system down to the level of equipment. The following are analyzed： the potential failure modes of various function modules （such as the power generation module, the power distribution module and the lifting module） in the LCVPS, as well as those of specific devices, which realize the corresponding functions in these modules. The causes, the local effects and the end effects of the potential failures are also discussed. Finally, by using the Matlab to perform modeling and failure simulation analysis for the LCVPS, the quantitative failure data are obtained, which is helpful in taking effective measures to remove failures as soon as possible and to enhance reliability of the system.
