Abstract

The invention discloses a focusing solar simulator energy flux density measuring device and method and relates to the field of energy flux detection. The device and the method prevent large errors of facular energy flux density and facular total power acquired by means of a conventional measuring method. The device comprises a xenon lamp unit, a facular receiving unit, and a facular image acquiring and processing unit. A water-cooling diffuse reflection target is installed on an elevator. Focusing faculae generated by the xenon lamp unit converge on the surface of the water-cooling diffuse reflection target of the facular receiving unit. A high-temperature heat-flow meter is installed on the center of the water-cooling diffuse reflection target. A mobile diffuse reflection target moves along a motion guide rail. When the mobile diffuse reflection target moves to cover the high-temperature heat-flow meter, the facular image acquiring and processing unit acquires the images of the faculae and acquires the gray values of the faculae at the corresponding area of the high-temperature heat-flow meter. According to the readings of the high-temperature heat-flow meter and the gray values of the faculae at the corresponding area, a scale factor of the pixel gray values of the faculae and facular energy flux density values is calibrated. The facular energy flux density is obtained according to the grayscale image of the overall faculae is acquired.

Description

technical field [0001] The invention relates to an energy flow density detection device of a solar simulator in the field of energy flow detection, in particular to an energy flow density measurement device of a focused high-power solar simulator. Background technique [0002] The solar simulator is an experimental and calibration device that uses artificial light sources instead of sunlight to simulate the characteristics of solar radiation indoors. A focusing solar simulator can produce a spot with a high focusing ratio, and its peak energy flow is usually as high as hundreds or even thousands of kW / m 2 . It is mainly used to simulate the focused spot of high-energy flow produced by the concentrator place of the solar thermal power station, so that it can be used in the laboratory environment for heat absorbers such as trough heat absorbers, tower heat absorbers, and dish Stirling machines. Thermal reactors for thermal performance studies. At the same time, the focused ...
