Problems solved by technology
[0004] However, due to atmospheric refraction, time accumulation error, mechanical error and other reasons, after the open-loop adjustment is completed, the main optical axis of the device cannot be directly aligned with the sun, which reduces the working efficiency of the power generation device.
At the same time, the existing solar tracking control devices all use a single tracking controller to control a single power generation system. This structure is not conducive to the networking of the tracking device and increases the construction cost during the construction of the power station.

Description
technical field [0001] The invention relates to the field of solar power generation, in particular to a sun tracking control system and control method for a dish-type solar power generation device. Background technique [0002] With the development of economy and society, human beings put forward higher and higher requirements for energy. At present, our energy mainly depends on fossil fuels such as coal, oil, and natural gas. On the one hand, their reserves are limited. It is estimated that the current oil reserves in the world are only enough to continue mining for 30 years; on the other hand, the combustion of fossil fuels will emit carbon dioxide and sulfur oxidation. Harmful gases such as pollutants will pollute the environment. Especially the smog that has affected most parts of my country in recent years is mainly caused by the burning of fossil fuels. [0003] Based on the background of the current global energy shortage, solar energy, as a clean energy, has the ad...
