太阳能电池阵的功率预测

The Power Prediction of the Solar Cell Array

为实现卫星太阳能电池阵的功率预测,在工程上常用太阳能电池的单指数等效电路模型的基础上,考虑了串联电阻,提高了I-V特性方程模型精度。利用某地球同步卫星在轨6年的太阳能电池阵的输出功率数据,求出了太阳能电池阵在卫星寿命过程中每年的衰减因子,代入功率预测模型,预测结果表明,预测精度可以满足工程上的要求。该功率预测模型适用于其他同类型地球同步轨道卫星的太阳能电池阵的功率预测。

In order to achieve the power prediction of satellite solar array, based on the single index equivalent circuit model of solar cell commonly used in engineering, considered the series resistance, improved the precision of the I-V characteristic equation model. Using a geostationary satellite on-orbit six years of the output power data of the solar cell array, calculate the attenuation factor of the solar array in the process of satellite life by per year, generation into the power prediction model, the prediction results show that the prediction accuracy can satisfy the requirement of engineering. The power prediction model applicable to other same type of geosynchronous orbit satellite solar array power prediction.
