Research on Vessel Integrated Electric Power System′s Built-in Test

舰船综合电力系统机内测试(built-in test,BIT)研究分析对提高武器装备的测试性设计水平,增强装备系统的可用性,提高战备完好率,降低全寿命周期费用具有重要的作用;通过从国内外机内测试发展现状展开分析,对舰船综合电力系统进行测试性建模和测试性层次划分,将系统分为发电机本体、励磁系统和整流系统3个部分;详细分析了各分系统的故障模式并从工程可行的角度提出了相应的测试参数和测试点;从降低系统虚警率的角度对系统的状态监测、故障检测和故障隔离的进行了常规流程设计;最后,提出了系统级BIT结构框架图,为后续机电系统测试性进一步研究打下了基础。

It is important of research and analysis on vesselintegrated electric power system＇s testability design and analysis to improve the weaponry＇s testability level,strengthen the equipment system＇s usability,increase the combat readiness and reduce the life cycle cost.This paper starts analyzing the development of BIT at home and abroad,builds test model on vessel integrated electric power system and divides level.The system is divided into three parts,the generator,the excitation system and the rectifier system.Each subsystem＇s fault models are analyzed in detail and the test parameters and test points are put forward in engineering practical aspect.The system＇s process of condition monitoring,fault detection and fault isolation are designed.Finally,the systemlevel BIT structure diagram is proposed in terms of reducing the rate of false alarm,laying a solid foundation for the follow-up test research of electromechanical equipment.
