The invention discloses a system and a method of correcting heliostat deviation by using an unmanned aerial vehicle. The system comprises a heat absorption device of a tower type solar thermal power station, a heliostat in a heliostat field, a heliostat field control system, an unmanned aerial vehicle central control system, a transmitter, and a receiver. The heliostat is used for the real-time tracking of the sun under the control of the heliostat field control system, and by adopting bidirectional adjustment of an azimuth and an altitude angle, and incident sunlight is reflected to the heat absorption device of the tower type solar thermal power station. Laser is used as a light source for a correction process, and therefore the system is not dependent on the sunlight, and then the correction process can be carried out in daytime or nighttime, and is not affected by shielding of clouds. The system can work together with the normal operation of the heliostat, and the heliostat scheduling and the power generation efficiency are not affected. The correction method provided by the invention is used to provide the same verification precision for every heliostat in the heliostat field. By adopting a preset program, the automatic operation of the full correction process is realized quickly and effectively.
Description
technical field [0001] The invention relates to the field of solar thermal power generation, in particular to a system and method for correcting deviations of heliostats with an unmanned aerial vehicle used in a tower-type solar thermal power generation system. Background technique [0002] At present, the common heliostat tracking deviation detection generally adopts non-contact visual detection method, which uses the camera to collect the spot image formed by the heliostat on the target, and then uses image processing to fit and calculate the geometric center of the spot, and then compares with the target. The center comparison analysis obtains the tracking deviation value, and realizes the estimation and error correction of the heliostat controller parameters. Since a large number of cameras need to be installed in a large-scale mirror field, and there are certain requirements for image processing accuracy, this method of deviation detection for heliostats may cause an ex...
