Abstract

The invention provides an all-sky radiation continuous distribution fine measurement device and a working method.The device comprises a tracking system and a measurement system, the tracking system is a double-shaft tracking system, the double-shaft tracking system comprises an elevating angle shaft and an azimuth angle shaft, the measurement system is fixed to one side of the double-shaft tracking system through the azimuth angle shaft, and the azimuth angle shaft is fixed to the other side of the double-shaft tracking system. The tracking system adjusts the elevation angle of the measuring system through an elevation angle shaft, and the tracking system adjusts the azimuth angle of the measuring system through an azimuth angle shaft. According to the invention, distribution information of solar radiation along with angle change can be measured finely, all-sky distribution of solar radiation under a real condition, namely a distribution state of'strong solar center radiation and decreasing surrounding intensity ', can be reflected accurately, and the defect of single measurement result value of a traditional solar radiation measurement system instrument is eliminated; calculation is simple and convenient, and the problem that image splicing of an all-sky scanner is time-consuming is avoided.

Description

technical field [0001] The invention belongs to the field of radiation measurement, and in particular relates to a fine measurement device and working method for continuous distribution of radiation throughout the sky. Background technique [0002] Due to the limitation of fossil energy and increasingly severe environmental problems, human beings have begun to explore renewable energy and clean energy. As one of the most potential energy sources, solar energy has the universality of energy utilization, huge energy, cleanness and permanence. The sun transmits energy to the earth in the form of radiation, including direct radiation and diffuse radiation. The measurement of direct radiation is mostly done using a pyrheliometer with an open field of view of 5°, but it can only measure the solar radiation within the 5° field of view. Average value; the measurement of scattered radiation mostly uses the small ball with opening field of view to block the middle area of ​​the pyran...
