Problems solved by technology

[0002] In order to save energy, reduce emissions and protect the environment, countries around the world are promoting green and environmentally friendly energy. Solar power generation is a kind of green and environmentally friendly energy. At present, solar photovoltaic power generation mostly uses fixed photovoltaic panels. The disadvantage is that fixed photovoltaic panels cannot operate with the sun. The trajectory changes the light angle, so the power generation efficiency is low. Although the existing column tracking photovoltaic power station has high power generation efficiency, the disadvantages in use are high processing costs, high installation and transportation costs, and are not easy to install in remote rural areas and plateaus. Installation and use in mountainous areas

Embodiment

[0028] The specific steps are as follows:

[0029] 1) In the morning, after the sun rises, the ray tracing sensor enters the working state, and the ray tracing sensor provides horizontal azimuth and elevation angle adjustment signals to the microcontroller in real time;

[0030] 2) At dusk, the photovoltaic panel tracks the sunlight and turns to the west. When it detects that the voltage generated by the photovoltaic panel is lower than the set value, the intelligent controller controls the deceleration motor to rotate the platform to turn the photovoltaic panel towards the starting position in the morning, and then the control system enters a sleep state ;

[0031] 3) In windy weather, the wind speed sensor monitors the wind speed in real time, and the wind speed sensor monitors that the wind speed exceeds the set value, and the intelligent controller immediately controls the electric actuator to shrink, reducing the elevation angle of the photovoltaic panel and reducing the ...

Abstract

The invention provides a combined automatic tracking solar photovoltaic power station. The structure is that the combined automatic tracking solar photovoltaic power station is composed of screw machine piles, an annular track, a rotating platform, a supporting rack, a photovoltaic panel large frame, rollers and an intelligent controller. The lower ends of the screw machine piles are connected with the ground in a screwing way. The upper ends of the screw machine piles are connected with the annular track. The internal circle or the external circle of the annular track is groove-shaped. The rotating platform is connected with the annular track in a rolling way through the rollers. The upper part of the rotating platform is connected with the photovoltaic panel large frame through the supporting rack. Photovoltaic panels are inlaid in the upper surface of the photovoltaic panel large frame. The intelligent controller controls horizontal rotation and adjustment of the elevation angle of the photovoltaic panel large frame through a deceleration motor and an electric push rod. Full-automatic tracking, wind protection and electricity consumption sleep management at night can be truly realized, and easy unattended control can be realized.
