Problems solved by technology

[0004] For the sun trajectory tracking method, due to the changeable natural phenomenon, there will be a gap between the calculation and the actual situation, and the cumulative error cannot be eliminated during the tracking process. The attitude rotation of the solar panel is mainly driven by the rotation of the control motor, and there will also be a large gap in the angle positioning. large error, which reduces the accuracy of the system
Tracking on rainy days is a pure system energy drain
[0005] In the sensor detection and tracking method, the signal acquisition of the sensor has higher requirements on the external environment, and it is easy to misjudge in rainy days or external light sources
The difference in sensor selection will also affect the measurement accuracy

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] Such as figure 1 , figure 2 and image 3 Commonly shown, the present invention provides a solar ray tracing method for a three-phase limited solar ray tracing sensor device, the steps are as follows:

[0026] 1), Sun track tracking realization stage:

[0027] Obtain the position of the sun relative to the earth by consulting the astronomical algorithm of the sun trajectory; the local accurate time and longitude and latitude are required, and the altitude angle and azimuth angle of the sun are calculated by the following formula from the local time and geographic latitude (φ);

[0028] The local hour angle is represented by t, t=(hour*15+minute*0.25) degrees; the declination angle (δ) is the angle between the earth’s equatorial plane and the line connecting the sun and the center of the earth, and the declination angle of any day in a year δ:...

Abstract

The invention discloses a sun light ray tracking algorithm fusing a three-phase limitation sun light ray sensor and a light spot image sensor. The algorithm comprises the steps of (1) a sun trajectory tracking realizing stage; (2) a sensor tracking realizing stage; and (3) a light spot tracking method realizing stage. The sun light ray tracking algorithm fusing the three-phase limitation sun light ray sensor and the light spot image sensor is simple in design, low in cost, stable in operation, high in tracking precision, and capable of better representing practicability, economy and generalizability.

Description

technical field [0001] The invention relates to the technical field of solar photovoltaic power generation, in particular to a solar ray tracing algorithm for fusion of a three-phase limited solar ray sensor and a spot image sensor. Background technique [0002] Today's power generation technology in the power industry is mostly based on coal. However, due to the increasingly prominent problems of energy crisis and environmental pollution, the development of new energy is required for development. As an environmentally friendly and renewable public resource, sunlight has infinite potential. Comparable advantages and favored by the majority of developers. Today's solar power generation technology is relatively mature, but its development is slow due to issues such as production costs, photoelectric conversion efficiency, and materials. [0003] At present, solar photovoltaic power generation has been widely used in various industries, but due to the low photoelectric convers...
