基才层次故障树的地面电源诊断优化方法研究

导弹地面电源系统是一个集成度高、结构复杂的综合系统，采用传统的故障树分析方法，存在故障树复杂，分析量大等问题。针对该地面电源系统的复杂性，结合常规的故障树分析方法和层次化分析方法的优势，提出了层次故障树的分析方法，在构建故障诊断树后，将其应用到该电源系统的故障诊断策略优化中，达到了很好的效果。

Research of the optimization for ground power fault diagnosis based on hierarchical FTA

The missile ground power supply system is a high level of integration, complicated structure, and the comprehensive system. The traditional fault tree analysis method exists complex, large quantity, etc. In this paper, the complexity of the ground power supply system, combining general fault tree analysis method and the hierarchical analysis method, puts forward the advantage of the fault tree analysis method of hierarchy. After constructing the fault diagnosis tree, its application to the power system fault diagnosis of optimization strategy, achieves a good effect.
