Method and device for calculating condensation efficiency of heliostat based on actually measured wind pressure

The embodiment of the invention provides a method and device for calculating the condensation efficiency of a heliostat based on actually measured wind pressure, and the method comprises the steps: building a celestial equatorial coordinate system, and calculating the elevation angle and azimuth angle of the sun; acquiring position information of a preset heliostat and a heat absorption tower, determining a mirror surface cross arm distance corresponding to the heliostat, and calculating an elevation angle and an azimuth angle of the heliostat by combining the elevation angle and the azimuth angle of the sun and the mirror surface cross arm distance; establishing a finite element model; distributing a plurality of wind pressure measuring points in the sub-region of the heliostat, detecting a corresponding wind pressure time history to obtain an equivalent wind load time history of the sub-region, and importing the wind load time history into a finite element model for transient analysis to obtain a light cond
