摘　　要：针对新型飞机电源系统部件种类多、控制复杂以及电路级仿真运算量大、速度慢的特点,提出了基于行为模型的飞机电源系统电能部件的建模方法。从电能部件的输入输出出发,依据功率平衡关系,并且结合受控源,来描述部件功能特征。利用Simulink软件,建立了系统中的关键部件的行为模型,并且构建了整个电源系统仿真模型。通过该模型,开展了飞机电源系统的特性仿真研究。仿真结果表明,所建立模型简单、方便、可以反映部件和系统的行为特性,仿真速度比电路模型更快。Considering the feature of quantity of components control complex, and the circuit-level model simulation computes heavily and slowly in new aircraft power system, this paper proposed the modeling approach based on behavior model. According to the input/output feature of the electric components, this method combined the power balance equation with the controlled sources to described the function characteristics. Then, some key components in the system is modeled using Simulink, and the simulation model of the entire power system is established according to the power grid structure of the aircraft to carry out the study of the system charateristic. The simulation results show that the model is simple and convenient, and it can reflect the behavior characteristics of the components and the system prettywell.
