摘　　要：电源系统故障的有效诊断是保证电源系统安全可靠的重要途径。针对当前航空电源系统故障诊断存在的不足,提出一种寻址编码技术查询故障,并设计故障测试平台,设定故障检测门限,采集数据进行定量分析的新方法。寻址编码结合实测数据定量分析的方法,提高了故障诊断的效率和精度。以某战机的应急电源系统为例,实验验证了此方法故障定位精确、测试效率高,有效解决了航空电源系统故障诊断不准确的问题。The effective power system fault diagnosis is an important approach to ensure the power system safe and reliable. In view of the defciency existing in the current fault diagnosis of aircraft power supply system, this paper proposed a kind of addressing and coding tech-nology to query the fault and designed the fault test platform. The new method set the fault detection threshold and collected the data to carry out the quantitative analysis. Combined with the quantitative analysis of measured data, the addressing and coding method improved the ef-fciency and accuracy of fault diagnosis. Taking the emergency power supply system of certain aircraft for example, this paper verifes the ac-curate fault location and the high test effciency, which effectively solves the problem of inaccurate fault diagnosis in aircraft power system.
