Automatic sun chasing gesture control system for solar power generation device

Abstract

The invention discloses an automatic sun chasing gesture control system for a solar power generation device, which comprises a motor execution unit. The motor execution unit is connected with a control box; the control box is provided with a main controller and a power circuit; an inner clock circuit and a main control operation procedure are stored in the main controller; the main controller line is connected with a sun position sensor for feeding position coordinate information of the sun in an image back and an upper computer used for manually setting parameters of the latitude and the longitude where the solar power generation device is located; the main controller calculates and obtains the azimuth angle and the elevation angle of the sun according to the input latitude and longitude parameters and the real-time time parameters provided by the inner clock and then controls a solar photovoltaic panel to rotate to the calculated and obtained azimuth angle and the elevation angle of the sun; and the main controller controls the solar photovoltaic panel to rotate to the calibrated sun position coordinate according to the real-time sun position coordinate information inputted by the sun position sensor, and high-precision control on the sun chasing gesture of the power generation device can be realized.

Description

technical field [0001] The invention relates to the technical field of solar energy applications, in particular to an automatic control system for tracking the attitude of a solar power generation device. Background technique [0002] As an environmentally friendly, green and sustainable new energy source, solar energy is being actively researched on the development and utilization of solar energy all over the world. Theoretical studies have shown that compared with fixed-point solar power generation devices, automatic tracking solar power generation devices can increase the efficiency of solar energy reception by 35%. It is a new technology and product highly recommended in the field of solar power generation in the world at this stage. [0003] The automatic tracking solar power generation device is that the solar photovoltaic panel is aimed at the sun in real time, and keeps the sun's rays directly shining on the solar photovoltaic panel in real time. Since the azimuth ...

Problems solved by technology

One improvement method is to use photoresistors or photodiodes as feedback to reduce the system's dependence on the accuracy of mechanical transmissions. However, due to the large error in the detection of the sun position by photoresistors or photodiodes, they are more susceptible to interference. It can only achieve rough control of the sun-tracking attitude, but cannot achieve high-precision control of the sun-tracking attitude
