Abstract

The invention discloses a heliostat calibration system and a calibration method for a tower solar power generation system. The drive motor of the heliostat is controlled to rotate according to a predetermined path through a first control unit, so that the reflected light spot of the heliostat falls into the acquisition of an image sensor. Within the range, after the image sensor collects the reflected light spot image, the second control unit coordinates the first control unit to fine-tune the attitude of the heliostat according to the reflected light spot image obtained by the image sensor, so that the reflected light spot is located at the designated position of the heliostat, and Record the attitude information of the heliostat at this time. Combined with the absolute position information of the image sensor and the sun angle to calibrate the heliostat motion model, the calibration accuracy is high, the system error is small, the calibration speed is fast, and the system operation cost is low.

Description

technical field [0001] The invention relates to the field of solar power generation systems, in particular to a heliostat calibration system and a calibration method for a tower solar power generation system. Background technique [0002] As a clean and renewable energy, solar energy has been applied more and more, especially photothermal power generation technology is an emerging solar energy utilization technology after photovoltaic power generation technology. Among several photothermal power generation technologies, tower-type solar thermal power generation uses a large number of heliostats to gather sunlight to the heat absorber installed on the top of the heat-absorbing tower, heats the working medium, generates steam, and drives the steam turbine to drive the generator. generate electricity. Among them, heliostat tracking movement and calibration is one of the key technologies of tower solar thermal power generation. The whole heliostat field is composed of thousands...
