摘　　要：在飞机备用电源动态性能的优化中,为了在飞行应急状态下为机载重要设备提供不间断电源,保证安全工作,提出了准确计算备用电源系统数学模型并建立仿真模型,验证系统加减载特性。以某主流机型备用恒频交流电源为研究对象,计算电源模块和控制模块各个环节的数学模型,在MATLAB/SIMULINK环境下,按照数学模型和系统负载控制原理搭建仿真模型,运行仿真飞机备用交流电源不同工作负载状态,实现系统的动态仿真。将仿真结果与相应标准进行对比,得出结论,上述电源加减载特性良好。In the paper, a standby constant frequency AC power was taken as the study object, its mathematic model of every element in the power module ＆ control module were calculated. Under the circumstance of MATLAB/ SIMULINK, the simulation model was built according to the mathematic model and equipment＇ s load operation principle. The system simulation was carried out on various conditions of the aircraft AC standby bus. The simulation results were compared with the parameter criterion in the relevant standard. The analysis results show that the AC power＇s load characteristic is well.
