Method, system and equipment for predicting mirror field outlet temperature of trough type photo-thermal power station

The invention provides a method, a system and equipment for predicting the mirror field outlet temperature of a trough type photo-thermal power station. The method comprises the following steps: S101, obtaining actual operation parameters of the trough type photo-thermal power station in a preset time period; S102, substituting the actual operation parameters of the slot type photo-thermal power station in the preset time period into a pre-established temperature prediction model so as to determine the actual value of the optical efficiency of the heat collector; S103, according to the temperature prediction model, the actual value of the optical efficiency of the heat collector and the predicted value of the direct solar radiation intensity in the to-be-predicted time period, determining the predicted value of the outlet temperature of the mirror field of the trough type photo-thermal power station; according to the invention, the change of the mirror surface field can be predicted more accurately; accurate
