Abstract：Trough solar thermal power generation is the most mature photovoltaic power generation technology and has great development potential. The mirror field of trough photothermal power station is a key link in the energy conversion of photothermal power station. By tracking the sun, the rays of the sun are refracted onto the absorption tube, which is the foundation for the subsequent heat exchange and power generation process. According to the energy loss of solar radiation in trough concentrator, the mirror field efficiency mathematical model of trough photothermal power station is established, which can calculate the mirror field efficiency of various types of trough concentrator at any time in any region. The temporal and spatial factors and concentrator factors that affect the mirror field efficiency of the trough type photothermal power station are simulated and analyzed, including the influence of seasonal variation, the geographical location, the shape of the trough type concentrator, the spacing and arrangement mode on the mirror field efficiency of the trough type photothermal power station. The simulation result shows that the mirror field efficiency is higher in summer; the higher the latitude is, the higher the average mirror field efficiency is; and longitude affects the overall working time of the thermal power station.
