The simulation of 50MW trough solar thermal power generation system in Zhangjiakou is carried out for 8760 hours in a year. The simulation parameters are compared with Sam software to verify the accuracy of the software. The solar multiple and heat storage time configuration of the design parameters of the power station are optimized with low lcoe as the optimization objective. The static investment scale and the existing technology of the actual project are also considered Based on the small investment increase in exchange for large lcoe decrease, the solar multiple and heat storage time are optimized again; the influence of solar multiple and heat storage time on annual power generation is analyzed; the influence of solar radiation, flow rate of heat exchange fluid, ambient temperature and wind speed on collector efficiency is analyzed.<br>
