摘要 飞机配电系统的自动化是现代飞机供电系统发展的重要方向。针对目前对飞机自动配电系统建模仿真研究较少的现状,本文建立了完整的飞机自动配电系统仿真模型并进行了仿真研究。以中国国家军用标准(以下简称国军标)飞机供电特性为依据,建立了飞机配电系统中各主要部件以及故障产生模块的数字模型,推导了各部件控制信号的逻辑关系,提出了一种锁定关断控制信号的建模新方法。将所建模型应用于某新型飞机的配电系统中进行仿真,通过对过压、欠压两种故障情况下仿真与实验结果的对比,证明了所建模型能很好实现非正常状态下的保护功能。将所建立的模型略做修改,即可移植到其他飞机配电系统中,可见模型通用性强。 Automation of the aircraft power distribution system is an important aspect in the development of modern aircraft electric power system. There is a lack of the research on the modeling and the simulation of the automatic power distribution system, so the models are established to be simulated. According to the aircraft electric power characteristics in the related criterion, models of important components in the distribution system and models caused by the faults are established. The control methods and logic relations of these components are induced. A new method for establishing the model of locking the off signal is proposed. These established models are applied to the distribution system of a new type of aircraft. The comparison between simulation and experimental results under the over voltage and the under voltage condition verifies that models can perform the protect function well in the abnormal operation. Because the models can be applied to other power distribution system by modifying some parameters of the models, thus they are universal models.
