多电飞机变速变频电力系统的发电机之间无法并联供电,通常采用冗余供电方式来提高供电可靠性。为模拟仿真多电飞机变速变频电力系统的运行状态,展现故障情况下的电源切换过程,在分析变速变频电力系统结构及主要器件原理的基础上,基于Simulink平台,利用功能性建模方法搭建了包括变频发电机、汇流条控制单元、整流器等主要元件在内的综合仿真模型,并利用逻辑元件实现了电源切换功能建模,最后用算例进行了稳态状态下模拟仿真和故障状态下电源切换验证。
Multi-aircraft variable frequency power system generators can not be parallel between the power supply, usually using redundant power supply to improve power supply reliability. In order to simulate the operation state of variable frequency variable frequency power system of multiplayer aircraft and to show the process of power switching under fault conditions, based on the analysis of the structure of variable speed variable frequency power system and the principle of main devices, the functional modeling method was used to build Including the main components such as inverter generator, busbar control unit, rectifier and so on, and makes use of logic elements to realize the power switching function modeling. Finally, with the examples, the simulation and the power supply under fault condition Switch authentication.
