摘　　要：飞机供电系统的布局设计与控制逻辑是飞机系统设计的重要环节,且其对系统的可靠性、容错供电和余度等特性具有一定影响;对飞机电源系统进行仿真建模研究,在支持各种物理系统建模的Dymola平台下搭建了数字仿真模型,包括交流发电机、变压整流器、电源系统接触器和过欠压、过欠频检测模块等部件模型,并利用各个部件模型搭建了供电系统模型,同时利用Modelica语言完成系统逻辑设计,对整个系统进行仿真;数字仿真结果表明电源系统模型基本能够完成自动配电、自动隔离故障,达到设计要求,为飞机系统设计提供了理论支持。The design of structure and the control logic of aircraft power supply system are important parts of aircraft system design,which concern its reliability,redundancy and fault tolerance performance.Digital simulation modeling research and optimization are carried out on completed the aircraft power system.Simulation models including AC generator,TRU（Transformer Rectifier Unit）,contactor,overvoltage-undervoltage and overfrequency-underfrequency detection modules are built in Dymola software which can be applicated in a variety of physical systems.The power system is established with these component models and then using the Modelica language to complete the system logic design.Simulation results show that the power system model meets the design requirements.Automatic distribution,automatic fault isolation and it provide the theoretical basis for aircraft power supply system.
