Problems solved by technology

Using this system can get better correction accuracy of heliostat tracking error, but there are also obvious defects and deficiencies: First, it is necessary to specially install a four-quadrant sun position sensor on each heliostat device. Hundreds of four-quadrant solar position sensors will be needed in the tower power station system, so the cost of this type of error correction system is relatively high, which is not conducive to the large-scale construction and promotion of tower power stations; The tracking error correction of the heliostat increases the dependence of the tower power station on the system, and also increases the maintenance cost and workload of the tower power station

Embodiment Construction

[0048] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0049] figure 1 It is a structural schematic diagram of an embodiment of the heliostat error correction system in the present invention. As shown in the figure, the error correction system includes a heliostat mirror field subsystem 1 , an image acquisition and processing subsystem 5 and a heliostat control subsystem 8 .

[0050] The heliostat mirror field subsystem 1 includes a heat collector 2 , a deflection correction plate 3 and a heliostat device 4 . The heat collector 2 is used to absorb the solar radiation reflected by the heliostat, convert it into heat energy, and transmit it to the heat transfer working medium in the heat collector 2 . The deviation correcting plate 3 is a white flat plate with good Lambertian properties, used as a target for detecting the tracking error of the heliostat. Feature mark points can be set on the de...

One heliostat device is provided with a heliostat control unit, and one master control unit controls at least one heliostat control unit.

Description

technical field [0001] The invention relates to the field of photothermal power generation, in particular to a heliostat error correction system and method for a solar tower photothermal power station. Background technique [0002] Solar thermal power generation technology (English name Concentrating Solar Power, referred to as CSP) uses a large area of ​​mirrors to reflect solar radiation energy to the collector, and the collector converts solar radiation energy into heat energy, and generates power through a thermal cycle process. As an important way of large-scale solar power generation, solar thermal power generation has a series of obvious advantages. First of all, its carbon emission in the whole life cycle is very low, only 18g / kWh according to foreign research. In addition, this technology has the lowest cost among the existing solar power generation technologies, and it is easier to quickly realize large-scale industrialization. In addition, solar thermal power ge...
