Solar lighting simulation method with manually adjustable elevation angle

Abstract

The invention provides a solar lighting simulation device and method with a manually adjustable elevation angle and belongs to the technical field of sun followers. The device provided by the invention is characterized in that a reflector is arranged on a reflector rotating mechanism; a dip angle measurement device is connected with the reflector; a reflector rotation regulating mechanism is arranged at one end of the reflector rotating mechanism which is arranged on a moving table; the moving table is arranged on a reflector horizontal displacement motion guide rail connected with a horizontal displacement measuring device; and a solar simulator is corresponding to the reflector. The method provided by the invention comprises the following steps of: measuring the value of the vertical distance h between the central line of an emergent light beam of the solar simulator and a sun follower; manually regulating the displacement of the reflector on the horizontal displacement motion guide rail and changing the horizontal displacement of the reflector to x; manually regulating the reflector rotation regulating mechanism and regulating the dip angle of the reflector relative to the horizontal plane to beta; and acquiring required simulated sunlight with an sun elevation angle alpha.

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 with an artificially adjustable elevation angle. Background technique [0002] With the development of solar energy and the increasing attention paid to sun monitoring, a large number of sun tracking devices or sun trackers that can automatically track the sun have emerged. Sun tracking devices or sun trackers are widely used in solar power generation, meteorological monitoring (solar radiation measurement, atmosphere), etc. In order to ensure tracking accuracy, most sun trackers adopt a closed-loop working mode, using photoelectric sensors such as photocells, photodiodes, and imaging devices to provide feedback on the sun's pointing deviation. In the debugging, testing and pointing accuracy inspection of sun tracking equipment or sun trackers, the sun illumination environment is one of the essential t...

Problems solved by technology

[0009] The second problem is that the "single-axis turntable" scheme usually needs to change the mechanical design of the sun tracking device or sun tracker

For the sun tracking equipment or sun tracker products that have been formed, adding a mechanical device that is only used for testing may cause a series of problems, including cost, strength, etc.
