摘要
针对太阳同步轨道立方星,提出了一种计算电池阵平均输出功率的方法。首先利用卫星仿真工具包(satellite tool kit,STK)获得光照期太阳矢量与电池阵平面夹角;然后导入MATLAB中计算不同夹角对应的瞬时输出功率与时间的乘积,逐次累加得到总能量;最后用总能量除以整个光照周期,即可获得电池阵平均输出功率。该方法简明直观,易于编程计算,适用于三轴稳定立方星太阳电池阵平均输出功率的计算。
In this paper,a method for calculating the average power generated by solar arrays is proposed for CubeSat,which runs on the sun-synchronous orbit.Firstly,satellite tool kit(STK)is used to obtain the angles between sun vectors and solar panels during the light period.Secondly,these angles are imported into MATLAB to calculate the products of instantaneous output power and time corresponding to different angles,and the total energy is accumulated successively.Finally,the average output power can be obtained by dividing the total energy by the time of entire light period.This method is simple,intuitive and easy to program,which is suitable for calculating the average output power of three-axis stabilized CubeSat.
