摘　　要：基于串联型顺序开关分流调节器(S4R)功率调节技术,针对卫星一次电源可能出现的所有故障,建立了仿真平台。该平台的建立克服了现有仿真平台无法仿真故障的不足,是辅助电源设计、故障复现及可靠性测试的有力手段。首先,参考大量文献数据,对故障类别进行分析汇总;然后,在Matlab/Simulink下搭建卫星电源故障仿真平台,并利用MatlabGUI作为操作界面;最后进行仿真验证,结果表明该平台可根据故障发生部位及注入量的大小正确反映出故障输出结果。Based on Series Sequential Switching Shunt Regulator（S4R）, aiming to all the faults of satellite electrical power system might happened, a platform is built. The fault-simula- tion platform can make up for a deficiency of simulation platform, and it is useful for electrical power system design and failure reproduction. Firstly, refer to a large number of literature, and summary the fault category~ secondly, set up a fault-simulation platform with Matlab/Simulink, and use MatlabGUI as operation interface; thirdly, simulation results show, it can output the correct result according to the fault location and the size of the injection rate.
