微小卫星电源系统的母线性能分析

Dynamics Analysis of the Micro Satellite Power System

建立以母线为核心的分流器,蓄电池充电调节器(BCR),蓄电池放电调节器(BDR)和太阳阵的交流小信号模型:导出母线动态阻抗、稳定性、瞬态响应和纹波的分析方法,并利用该方法举例分析了某一电源系统的性能。此外,还利用 Power Simulation(PSIM)电源系统仿真软件对该电源系统进行了仿真,验证了理论分析方法的正确性。

The small signal AC models of the shunt, the battery charge regulator （BCR） and the battery discharge regulator （BDR） are developed. The equations and methods for computing the bus dynamics are derived. A power system example is analyzed in terms of his method. In addition,the power system is also simulated by PSIM power simulation software for verifying the theoretical method.
