基于热模型的飞机电源电力系统鲁棒性仿真

Simulation Research on Robustness of Aircraft Power System Based on Thermal Model

目前世界飞行器的发展方向,日益趋向于节约能源,降低成本,提高系统效率。在这一趋势之下,飞机电力系统作为飞行器日益重要的组成部分,受到越来越多的关注。提出了一种基于热模型的飞机电源电力系统综合评估技术,建立了飞机电力系统各组成部分的数学模型。采用AMESim软件,构建飞机电力系统的发电机、整流装置、锂电池模型,并进行仿真分析。通过分析仿真结果得出飞机电力系统的状态评估结果,结果表明,交流供电网络符合国军标标准,抗波动裕度为79.17%,鲁棒性满足要求。

At present,the development direction of aircraft in the world is increasingly to save energy,reduce costs and improve system efficiency.In this trend,aircraft power system as an increasingly important part of aircraft has attracted more attention.Proposes a comprehensive evaluation technology of aircraft power system based on thermal model and establishes the mathematical model of each part of aircraft power system AMESim software and used to build the models of generator rectifier device and lithium battery of the power system and conduct the simulation analysis.The evaluation results of the aircraft power system are obtained which show that the AC power supply network meets the national military standard with the anti fluctuation margin of 79.17%,and the robustness meets the requirements.
