摘　　要：针对月球基地昼夜持续的能源供应,提出了一种基于月壤储热的碟式斯特林光热发电系统。采用有限时间热力学方法建立了该系统的昼夜持续供能理论模型,并通过MATLAB Simulink对该系统的供能特性进行了案例研究和关键参数分析。结果表明该系统在月球日间和夜间的输出功率和效率都会逐渐降低,月球日间和夜间的平均输出功率分别为10.7 k W和7.1 k W。由于对月球资源的充分利用,系统总的能源效率可达到40.39%,可用于月球基地昼夜持续的能源供应。提高碟式集热器集热温度和增加储热子系统储热质量有助于月球日间的能源供应,提高储热子系统初始储热温度有助于月球夜间的能源供应。该文的研究结果为解决月球基地能源供应问题提出了一种新途径。To address the continuous energy supply for lunar bases during the lunar day and night,a dish Stirling solar thermal power generation system based on lunar regolith heat storage is pro-posed.A theoretical model using the finite-time thermodynamic method is established to analyze the system's circadian continuous energy supply.Additionally,a case study and key parameter analysis of the system's energy supply characteristics are conducted using MATLAB Simulink.The results indicate that both the output power and efficiency of the system gradually decrease during the lunar day and night.The average output power during the lunar day and night is 10.7 kW and 7.1 kW,respectively.With the efficient utilization of lunar resources,the overall energy efficiency of the sys-tem can reach 40.39%,making it suitable for the continuous energy supply of lunar bases.Improving the collecting temperature of the dish collector or increasing the thermal storage mass of the heat storage subsystem contributes to the energy supply during the lunar day.Similarly,improving the initial thermal storage temperature of the heat storage subsystem aids in the energy supply during the lunar night.The research findings offer a new solution to the energy supply problem for lunar bases.
