Abstract

For this purpose,this paper proposes a solar airship equivalent circuit topology power evaluation method. This method constructs a curved array equivalent circuit model, conducts high-fidelity power evaluation research,and fully considers the impact of the large-scale curved surface of the airship body on irradiation,as well as the power topology of solar cell array on the airship surface. Firstly,the parametric model of the airship,solar irradiation and irradiation discretization model were constructed. Then,fully considering the actual series-parallel connection form of the photovoltaic array,a solar airship equivalent circuit topology power estimation method was proposed. Finally,it was compared with the irradiation discrete power accumulation method,and the differences of two power evaluation methods under different flight conditions were analyzed. The results show that the worse the irradiation uniformity in the series direction of the photovoltaic array on airship surface,the greater the error of the traditional power accumulation method compared with the proposed method,and the relative error even exceeds 120% in high latitudes. Therefore,the equivalent circuit topology method proposed in this article is recommended for solar airship surface power estimation.
