The invention relates to a secondary reflection pointing correction system and method for heliostats. The secondary reflection pointing correction system for the heliostats at least comprises a target, image acquisition systems and an upper computer; the target is mounted at the center of a focal plane of a heat absorber, the illumination range of the target covers a secondary reflector disc, eachimage acquisition system is fixed to the mirror surface of the corresponding heliostat, and the direction of a view field is identical to that of the reflecting surface of each heliostat; an opticalaxis vector of each image acquisition system is parallel to a normal vector of the mirror surface of the corresponding heliostat, and the upper computer is connected with all the heliostats and the image acquisition systems and used for acquiring data of the image acquisition systems and controlling the rotation of the heliostats. According to the system and the method, the target (a high-brightness light source or a marker) on the focal plane of the heat absorber is photographed by the image acquisition systems mounted on the mirror surfaces of the heliostats in order to carry out secondary reflection pointing correction on the heliostats, and all the heliostats provided with the image acquisition systems in a whole mirror field can be corrected at the same time.
Description
technical field [0001] The invention relates to a heliostat secondary reflection pointing correction system and method, and belongs to the technical field of heliostat secondary reflection pointing correction. Background technique [0002] Secondary reflection solar thermal power generation technology is a new type of tower solar power generation technology. A secondary reflection tower is installed in the center of the mirror field of the secondary reflection solar thermal power station, and a secondary reflection mirror disk is installed on the tower. The heliostat reflects the solar spot to the secondary reflector disk to complete the primary reflection, and then reflects it to the heat absorber installed near the ground through the secondary reflector disk to complete the secondary reflection to obtain solar energy with higher energy density for use Power generation, so the tower secondary reflector is one of the key factors affecting power generation efficiency. Reflec...
