摘　　要：临近空间长航时飞行器(平流层飞艇、太阳能飞机、高空科学气球等)是目前高空平台(HAPS)的一种发展趋势。目前临近空间长航时飞行器的能量来源主要是太阳电池,由于飞行器形状和体积不同,太阳电池安装位置和面积也不同。飞行器有效铺装面积有限,为了实现能量平衡,因需要铺装更大面积,会遇到不规则形状铺装的情形,但此时的发电预测计算过程比较复杂且速度较慢。该文提出一种基于太阳电池之间关系的发电模型,实现任意单块太阳电池快速预测光伏阵列发电功率。针对现有飞行器不规则铺设太阳电池的进行仿真分析,结果表明,该模型能够准确预测其发电能力,并解决了不规则太阳电池发电能力的准确预测计算过程复杂和速度较慢的问题,修正后的模型在计算用时效率上最多可减少50%。Long endurance aircraft in aerospace(stratospheric airship,solar powered plane,high altitude scientific balloon,etc.)can stay in near space for a long time.It is an ideal experimental platform for all kinds of loads and has become a research hotspot across the whole world in recent years.At present,the main energy source of near space long endurance aircraft is solar cells.Due to the different shape and volume of aerospace vehicles,the installation location and area of solar cells are also different.Some long endurance aircraft have limited pavement area.In order to achieve energy balance,solar cells with larger laying area will encounter irregular shape laying method.At this time,the calculation process of power generation prediction is complex and slow.This paper proposes a power generation model based on the relationship between solar cells,and the simulation analysis of the existing aircraft with irregular solar cells is carried out.The simulation results show that the model can accurately predict its power generation capacity.Meanwhile,the model can also solves the problem of complex and slows calculation process of irregular solar cell power generation capacity.
