摘　　要：针对多电飞机电力系统,建立基于负载变化的直流配电系统的模型。该模型包括发电及变压整流模块和直流-直流变换模块。研究分析直流供电系统块的电路拓扑结构,根据各模块负载不同特性设计反馈控制网络,优化控制飞机供电系统,提高飞机电源供电质量。搭建飞机直流供电系统的仿真模型,获得各项电路性能参数。将仿真获得的电路参数与美国军方军用标准MIL-STD-704F对比,仿真模型参数符合MIL-STD-704F的要求。仿真结果验证了所提飞机直流配电系统模型的合理性。A model of direct current（DC） distribution system of the more electric aircraft was established. The model includes the module of generator and transformer rectifier and module of DC-DC converters. Also, the author will research and analyze every circuit structure of the main distribution system, according to different characteristics of each module,design feedback control network to optimize the main distribution system of advanced aircraft and improve the quality of the aircraft power supply. The simulation results show that, the simulation model and control units of the distribution system, which the author set up, simulate the actual aircraft power distribution system, the model of steady state and transient performance satisfy the standard of aircraft power distribution system in the actual application.
