摘　　要：长期受粒子辐照、紫外辐照等因素的影响,地球同步卫星的太阳电池阵输出功率会出现较为明显的衰减。这里选取某地球同步卫星使用的背表面反射(BSR)硅太阳电池阵为研究对象,采用光强因子和温度因子修正太阳电池阵的输出功率,使用局部加权回归散点平滑法(LOWESS)分析了其在设计寿命期间的输出功率衰减规律;同时基于LOWESS建立了预测模型,用于硅太阳电池阵超寿运行期间的功率预测。实测数据表明:本文构建的预测模型可以满足超寿地球同步卫星在轨管理使用需求。The output power of solar cell array in geostationary orbit satellite will obviously attenuate because of the long-term effects of space environment factors such as particle radiation and ultraviolet radiation.The back surface reflection(BSR)silicon solar cell array used in certain geostationary orbit satellite is analyzed in this paper.First,the output power is modified with the light intensity factor and the temperature factor.Then,the attenuation rule of the solar cell array power during the design life is analyzed with the local weighted scatterplot smoothing(LOWESS)method.Finally,a prediction model based on the LOWESS regression method is proposed for the prediction of the power of the BSR silicon solar cell array over its life operation.The test data show that the prediction model proposed in this paper can meet the on-orbit management requirements of extra-served geostationary satellite.
