摘要：It proposed a single-exponential equivalent circuit model in order to predict the output power of geostationary satellite solar array. The key factors of the model are the short-circuit current ( ) , the open-circuit voltage( ) , the maximum power point current ( ) and the maximum power point voltage( ), which are used with corresponding coefficient to calculate the updated four parameters and I-V characteristics equation based on the new light intensity and temperature. Then, the power of various light intensity and temperature are calculated according to the provided voltage data, and a modified model is achieved by considering the attenuation factor. At last, this paper presents two experiments of the short-term and long-term solar array output power prediction. The comparison results of the predicted power and real power illustrate the prediction accuracy of 85%. Therefore, this power prediction model is sufficient for most engineering applications.
