    摘要:

    对航空无刷同步电机起动发电系统电动运行的励磁特性进行了理论分析,提出了交直流混合励磁方案,建立了系统的MATLAB/SIMULINK仿真模型。仿真结果表明,主发电机励磁电流平均值随励磁机励磁频率的升高而减小,且主发电机励磁电流脉动率随转速升高有唯一极小值点,该点可作为交直流励磁的切换点。

    Abstract:

    The excitation characteristic for starter/generator system working on starting process of brushless synchronous machine was analyzed in this paper first, and then a new excitation method is given, it was AC an DC excitation. Based on MATLAB/SIMULINK, the simulation model for the system was built. Simulation results state that the average current of main machine would decrease with the increase of excitation frequency and the rate of variation for excitation current had only one minimum value with the increase of speed, and the value just could be used for switching.
