Abstract

The embodiment of the invention discloses a heliostat calibration system and method. According to the technical scheme, the positions of a signal transmitting device, a signal receiving device and a heliostat to be calibrated are positioned, the theoretical transmitting angle and the theoretical receiving angle of at least one of an optical signal, an image signal and a radio signal are determined, a simultaneous equation is constructed according to the spatial positions of the at least one signal transmitting device, the at least one signal receiving device and the heliostat to be calibrated and according to the transmitting direction, the receiving direction and the angle of at least one of the optical signal, the image signal and the radio signal, so that the deviation parameter of the heliostat to be calibrated is determined, and the heliostat to be calibrated is calibrated according to the deviation parameter. By adopting the technical scheme provided by the invention, the aim of improving the calibration efficiency of the heliostat can be achieved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of solar power generation, and in particular to a calibration system and method for a heliostat. Background technique [0002] With the rapid development of economy and society, direct or indirect environmental problems such as smog and global warming are increasing, and people are paying more and more attention to environmental protection. Therefore, human society pays more and more attention to new energy sources, especially the utilization of solar energy. [0003] In central tower collector power plants, the collector on top of the collector tower receives sunlight reflected from a field of heliostats. The collector converts the energy into high-pressure, high-temperature steam output, which can then be sent to a turbine for electricity generation. Heliostats are generally installed on the ground around the tower. Each heliostat has a rigid reflective surface to track the s...
