太阳电池阵火星环境发电建模仿真

Modeling and Simulation for Power Generation of Solar Array in Martian Surface Environment

火星表面环境与近地空间环境有很大的不同,火星表面太阳电池阵发电受光照强度、火星尘、温度、太阳散射等因素影响,具有较大的复杂性。在调研国内外研究及探测成果的基础上,通过试验与建模计算相结合的方式,提出了一种火星表面太阳电池阵发电计算建模方法,建立了相应的仿真计算模型,应用于中国首次火星探测任务太阳电池阵设计及发电功率预算,成为整器能量平衡分析及设计的依据。该计算建模方法可为后续火星探测及其它深空探测任务提供参考。

The environments are very different between Martian Surface and near-earth space.To estimate the output power of the Solar Array on the Mars surface is not easy,which is affected by the solar radiation,temperature,dust and diffuse irradiance.A method to calculate the output power of Solar Array in Martian Surface Environment is proposed in this paper based on a survey to the results of research all over the world.Models about how the illumination,temperature and dust to affect the power generation of the Solar Array on Martian surface are established.Those numeric models and method are used to improve the power balance of the Mars Rover in the first Mars exploration mission of china and are a reference for the intending Mars and other deep-space exploration missions.
