摘　　要：三相短路过程是飞机电源系统中的一种典型暂态过程,在短路过程中电磁关系复杂、历时短暂。针对无刷交流同步发电机三相短路过程中存在的电磁量耦合及瞬态电流计算复杂难点,将短路过程分解为两个易分析过程,提出了一种利用叠加原理进行三相短路过程的等效分析方法对短路电流进行具体数学求解,解决了短路过程的模型求解问题。仿真结果表明,改进方法所得出的短路电流解也较好地符合了实际理论情况,并为飞机电源系统的数字仿真及供电品质提供了一定的参考。The process of three - phase short - circuit is a typical transient process in the aircraft power supply system, in the short - circuit process, the electromagnetic relation is complex and the process is short. In this paper, against the difficulties with electromagnetic coupling and short- circuit current computational complexity in the process of AC brushless synchronous generator three - phase short - circuit current, we took the short circuit process decomposed into two processes that are easy to analyze and used superposition principle for the specific mathematical solution of three - phase short - circuit current, to solve the problem of describing the transient process modeling. Simulation results show that, the solutions of the short - circuit current from this method are better conform to the ac- tual theory, which provides a reference for digital simulation of aircraft power supply system and analysis of power supply quality.
