Problems solved by technology

At the same time, solar energy is also unstable. Because the earth's surface is affected by day and night, seasons, geographical latitude, and random changing climate and natural conditions, the solar energy reaching a certain point is intermittent, and the direction and intensity of sunlight change continuously with time. These defects limit the large-scale development and utilization of solar energy resources

Abstract

The invention discloses a control circuit of a solar power generation tracking system. The control circuit of the solar power generation tracking system mainly consists of a tracking module, a single chip microcomputer controller, a driving unit and an energy conversion unit. The tracking module integrates photoelectric tracking and sun angle tracking, wherein the sun angle tracking is adopted at the first stage, and a photoelectric sensor is adopted at the second stage to correct tracking. The driving unit drives a stepping motor to run and respectively controls pole-around shaft rotation and pitch angle adjustment to achieve automatic sun tracking. The energy conversion unit utilizes a Stirling heat engine to convert solar energy heat into mechanical energy and utilizes a Stirling motor to convert the converted mechanical energy into electric energy. Wind speed and direction, illumination intensity and solar cell parameters are detected in real time while tracking. The receiving rate of a photovoltaic cell can be greatly improved, solar energy resources can be effectively and fully utilized, and the solar energy application field is widened.

Description

technical field [0001] The invention relates to the field of a solar power generation device, in particular to a control circuit of a solar power generation tracking system. Background technique [0002] The total amount of solar energy resources is very large. It is not only a primary energy source, but also a renewable energy source. It is a three-dimensional clean energy that is free to use and does not need to be transported. However, solar energy is dispersed. Although the total amount of solar radiation reaching the earth's surface is huge, its energy flux density is low. There is only about 1000W of solar energy per square meter on the ground. At the same time, solar energy is also unstable. Because the earth's surface is affected by day and night, seasons, geographical latitude, and random changing climate and natural conditions, the solar energy reaching a certain point is intermittent, and the direction and intensity of sunlight change continuously with time. The...
