3 terms and definitions

The following terms and definitions apply to this document. 3.1 Scattered radiation diffuseradiation; scatteringradiation Solar radiation is dispersed by air molecules, clouds and air in a variety of particles dispersed in a non-directional, but does not change its monochromatic composition of radiation. [GB/T 31163-2014, definition 5.14] 3.2 Tracking error When the tracker tracks the sun, the tracker's sun sensor axis is at an angle to the sun's direct light. 3.3 Snap angle snapangle In the case of direct solar radiation irradiance greater than or equal to 120W/m2, the tracker's sensor can effectively sense the sun's position , The maximum angle between the direct sunlight and the sensor axis. 3.4 Capture speed capturevelocity In the range of the capture angle, the tracker uses the photoelectric tracking mode to accurately find the tracking angular velocity of the sun position. 3.5 Shading angle The shading angle formed by the shading ball on the center of the total radiation table sensor carried by the tracker. see picture 1.
