Abstract

The invention relates to a device and a method for simulating sun illumination by manually adjusting an azimuth angle and belongs to the technical field of sun tracker detection. According to the device provided by the invention, a height adjusting device is connected with a plane reflecting mirror; a plane reflecting mirror inclined angle measuring device is connected with a plane reflecting mirror azimuth angle rotating mechanism; the plane reflecting mirror is connected with the plane reflecting mirror azimuth angle rotating mechanism through a rotating shaft and is fixed above a movable platform; the movable platform is arranged on a shifting moving guide rail; and a shifting measuring device is connected with the shifting moving guide rail. The method provided by the invention comprises the following steps: aligning light with the plane reflecting mirror; measuring the shortest vertical distance d from a principal optic axis of emergent light of a small-size solar simulator to a specific element surface of a to-be-detected device; and obtaining the azimuth angle gamma of the simulated sunlight according to a shifting measuring value y of the plane reflecting mirror and an inclined angle beta between the plane reflecting mirror and a vertical plane. The sun illumination simulation by manually adjusting the azimuth angle of the sunlight is realized.

Description

technical field [0001] The invention belongs to the technical field of solar tracker detection, and in particular relates to a solar illumination simulation device and method for manually adjusting the azimuth angle of sunlight. Background technique [0002] The sun tracking device can automatically find the sun. In the field of meteorological monitoring, it can ensure that the main optical axis of the measuring instruments such as direct solar radiation and total radiation is aligned with the sun. In addition, the sun tracking device can increase the energy flow density received by the solar power generation device, and is widely used in the field of solar power generation. At present, there have been many sun tracking devices or sun trackers that can automatically seek the sun. Most sun tracking devices use photoelectric sensors such as photodiodes, silicon photocells, and CCD imaging devices to measure the sun's pointing deviation and automatically track the sun in a clo...
