摘要
该文针对近地轨道卫星,以HXMT天文卫星为研究对象,对其电源系统进行仿真分析。利用轨道设计分析软件STK卫星工具包获取轨道数据以及卫星参数,并基于Simulink技术,着重考虑天文卫星运行过程中姿态变化、不同负载的运行等对电源系统的影响,对卫星的具体能量变化进行计算并建模。最终形成了一个电源系统能量平衡的仿真系统,对电源系统的能量变化给出实时的仿真,并给出了相应的仿真结果。可以判断系统达到平衡的状态,给出蓄电池容量变化,以及充放电等情况的曲线,显示直观效果。
The model of the energy balance aims at low earth circular orbit astronomical satellite HXMT. It receives the data from STK(Satellite Tool Kit), considers the influence to the power system by the attitude and different load courses, computes the energy changing, finally realizes the energy balance simulation of the system based on Simulink technology, and gives the results. You can judge the state of the system balance and get the state curves.
