Embodiment Construction

[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but it is not intended to limit the present invention.

[0036] The tower-type heliostat deviation correction system of the present invention includes a light filtering device 2, a heliostat 1, a photosensitive diode 4, a control system, a driving mechanism, and a two-axis motor (horizontal motor and pitch motor). The light filtering device is located on the surface of the heliostat, and the frequency range of the filtered light is 3.8X10 14 -7.9X10 14 HZ, the database corresponding to the frequency of the heliostat and the reflected light is pre-established in the control system. The sunlight is irradiated on the heliostat through the light filtering device, and then the heliostat reflects the filtered sunlight to the heat collector. A photosensitive diode is installed at each of the four corners of the heat collector. The control sys...

Abstract

The invention discloses an offset correction system and an offset correction method for a tower-type heliostat. The offset correction system comprises a light filter device, a heliostat, an offset correction system body, a control system and a drive mechanism, wherein the light filter device is positioned on the surface of the heliostat; the offset correction system is used for sending offset of the heliostat to the control system; the control system is used for controlling motion of the drive mechanism; and the drive mechanism is used for driving the heliostat to move according to an instruction output by the control system. The offset correction system solves the technical problems that a current tower-type heliostat is long in check cycle and is poor in timeliness of check results. By applying the offset correction method for the tower-type heliostat, offset correction can be simultaneously carried out on a plurality of heliostats without mutual influence, so that the check cycle is shortened.

Description

technical field [0001] The invention relates to the field of deviation correction of heliostats, in particular to a deviation correction system and a correction method of a tower type heliostat. Background technique [0002] Energy is the basis for human survival and the source of power for social development. As a renewable clean energy with wide distribution and abundant reserves, solar energy is an important direction for the development of energy technology and the key to implementing "two substitutions". [0003] At present, there are many kinds of solar concentrating heat collection systems, which are divided into three types according to the form of heat collectors: trough system, tower system and butterfly system. Tower-type solar thermal power generation uses independently tracked heliostats to reflect sunlight to a heat collector fixed on the top of the tower to generate high temperature and heat the working fluid to generate hot steam, which drives the steam turb...
