Performance Analysis of Lunar Dish Stirling Solar Thermal Power Generation System
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.
