Abstract

The invention provides a relative light intensity distribution measurement system for solar power concentrating light spots, and belongs to the field of performance measurement of solar utilization technologies. The measurement system comprises a light spot display, a water cooling system, a light spot measuring device and an assisting device, wherein the light spot display is arranged at a lightspot focusing position of a solar power concentrating system and used for displaying relative light intensity distribution of the light spots in a diffuse reflection manner; the water cooling system is used for keeping the light spot display to run at low temperature; the light spot measuring device comprises a CCD imaging instrument and a computer, and is used for measuring relative light intensity distribution of the light spots on the light spot display; the assisting device is used for assisting the light spot display and the light spot measuring device in work. With the adoption of the measurement system, the relative light intensity distribution of the solar power concentrating light spots can be accurately measured; the measuring accuracy is high; and valid data support is providedto improve the performances of the solar power concentrating system.

Description

technical field [0001] The invention relates to the field of performance measurement of solar energy utilization technology, in particular to a system for measuring the relative light intensity distribution of solar concentrated light spots. Background technique [0002] With the advancement of technology and the stimulation of domestic and foreign incentive policies, the field of solar energy utilization has shown an explosive growth trend in recent years. As an important branch in the field of solar energy utilization, solar concentrated photovoltaic technology is also developing rapidly. Reflective concentrating photovoltaic technology is popular because of its large concentrating area, high concentrating light intensity, and good concentrating uniformity. [0003] However, for reflective concentrating photovoltaic technology, such as a dish concentrating photovoltaic system, due to its large concentrating area and large concentrating spot, the concentrating intensity at...
