摘要
介绍了平流层飞艇再生能源系统的构成及功能,在再生能源能量平衡分析中建立了太阳电池阵列在平流层飞艇曲面铺装的模型和能源闭环模型,分析了能源消耗构成和全天24 h的能量平衡;且实现了太阳电池输出功率的可视化仿真。结果表明平流层飞艇能够在全天实现能量平衡。分析了能源系统的关键技术参数对能源系统的影响,结果显示:锂电池能量密度、太阳电池转换效率和锂电池充电效率是平流层飞艇能源系统的最关键技术参数。研究结果为平流层飞艇能量平衡分析方案论证和方案设计提供参考。
The structure and functions of stratospheric airship regenerative energy system were introduced.Pav-ing solar modules and energy closed loop modules were built in energy balance analysis.Power consumption of stratospheric airship and energy balance day and night were analyzed.In addition,visually simulated with the solar irradiance model was built and results verified energy balance day and night could achieve.Moreover,the pivotal technical parameters of energy system affecting energy system design were analyzed.Results verified power density of lithium ion battery,transforming proportion of solar cells and charging proportion of lithium ion battery were most pivotal technical parameters of regenerative energy system in stratospheric airship^s conceptual design.Important-ly,a reference of stratospheric airship energy balance analysis program demonstration and energy system design was provided.
