Abstract

The invention discloses a mirror field deviation rectifying method and device of a tower type fused salt photo-thermal power generation system. The method comprises the steps that a deployment mirror field of heliostats is divided into a plurality of deviation rectifying areas, the heliostats are heliostats in a photo-thermal power station adopting a tower type fused salt photo-thermal power generation system, and the heliostats are used for reflecting sunlight to a heat absorber of the photo-thermal power station; the heliostats are randomly selected to enter a rectification queue in a target rectification area of the multiple rectification areas; according to a preset correction scheme, parallel correction is carried out on the heliostats in the correction queue, the preset correction scheme is used for reducing mutual interference between the heliostats, and correction is used for correcting the deviation occurring when the heliostats track the moving trajectory of the sun. The technical problem that in the prior art, the deviation rectifying efficiency is low is solved.

Description

technical field [0001] The present application relates to the field of photothermal power generation, in particular, to a method and device for rectifying a mirror field of a tower-type molten salt photothermal power generation system. Background technique [0002] At present, some photothermal power stations use tower-type molten salt photothermal power generation system. The principle is to use heliostats to emit sunlight to the heat-absorbing screen on the heat-absorbing tower, and heat the molten salt, and the high-temperature molten salt heats the water. Water vapor is generated to drive a steam turbine to generate electricity. Whether the reflected light of the heliostat can be accurately reflected on the heat absorber, and whether it can be on the heat absorber along with the sun's orbit is very important for the solar thermal power station. Due to various reasons, when the heliostat tracks the sun's trajectory, there will be deviations, so the heliostat needs to be ...
