All-weather self-adapting double-shaft solar tracking system and control method thereof

Abstract

The invention discloses an all-weather self-adapting double-shaft solar tracking system and a control method thereof. The solar tracking system comprises an image recognition module, a control circuit module, a mechanical transmission tracking control module, a sensor and a photovoltaic array, wherein the image recognition module is formed by connecting a video camera with a computer in series; the control circuit module consists of a microprocessor; and the mechanism transmission tracking control module comprises a wind velocity indicator, a first frequency converter, a second frequency converter, a first motor, a second motor, a first speed regulating mechanism and a second speed regulating mechanism. In the method, the video camera is used for collecting images for analysis, and is combined with the microprocessor to exactly control postures of a solar panel. At the same time of exactly tracking all-weather solar azimuths and altitude angles and improving the solar utilization rate, the self-adopting capacity of the photovoltaic array under an all-weather condition particularly a severe weather condition can be improved, and the automatic recognition efficiency of faults and obstructions of a photovoltaic power station is enhanced. The solar tracking system also has the effect of theft prevention and enhances the safety and the reliability of the photovoltaic power station.

However, this type of tracking system has high cost, high energy consumption, and has certain limitations. It does not have functions such as snow protection and rainwater cleaning components, especially in severe weather (such as strong wind, rain, snow, etc.) and environmental conditions. Under severe weather conditions, the automatic tracking control cannot be effectively performed, and the solar array may even b
