    摘 要:電源系統(tǒng)故障的有效診斷是保證電源系統(tǒng)安全可靠的重要途徑。針對當前航空電源系統(tǒng)故障診斷存在的不足,提出一種尋址編碼技術(shù)查詢故障,并設(shè)計故障測試平臺,設(shè)定故障檢測門限,采集數(shù)據(jù)進行定量分析的新方法。尋址編碼結(jié)合實測數(shù)據(jù)定量分析的方法,提高了故障診斷的效率和精度。以某戰(zhàn)機的應(yīng)急電源系統(tǒng)為例,實驗驗證了此方法故障定位精確、測試效率高,有效解決了航空電源系統(tǒng)故障診斷不準確的問題。

    Abstract: The effective power system fault diagnosis is an important approach to ensure the power system safe and reliable. In view of the deficiency existing in the current fault diagnosis of aircraft power supply system, this paper proposed a kind of addressing and coding technology 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 efficiency and accuracy of fault diagnosis. Taking the emergency power supply system of certain aircraft for example, this paper verifies the accurate fault location and the high test efficiency, which effectively solves the problem of inaccurate fault diagnosis in aircraft power system.
    Key words: power system; fault detection and diagnosis; addressing and coding; quantitative analysis
