Automatic Tracking Control System Of Solar Power Generation

With the economic development, the population increase, the demand for energy increasing, the consumption of large quantities of the traditional and non-renewable resources, people become to take increasing emphasis on renewable resources. The use of solar energy has been for some time, but most of the system is fixed, the energy efficiency is not high. Therefore, from a practical point of view, this article design a solar power generation automatic tracking control system campaigning with the solar movement, making solar energy utilization efficiency was improved to some extent.Paper first describes the automatic solar tracking control system design principles, as well as solar power generation automatic tracking control system as a whole program, then presents a corresponding control program, and gave the mathematical model of the location of the sun relative to Earth. Second, regarding there is a certain mathematical modeling error of the position of the sun relative to Earth, the article proposed energy-based tracking control scheme of this control method carried out key research, and further designed and implemented based on this control approach, based on light-sensitive resistors, photodiodes, silicon photovoltaic cells, as well as photosensitive the light intensity sensor transistor. Finally, based on wind power, wind systems have been studied, for wind power, wind two sensors under the action of the wind force conducted a theoretical analysis, the article designed the wind, wind direction sensors, to realize wind, wind direction without interruption measurement, it will effectively protect the solar panels. As the solar panels placed on the field all year round, in this environment are often subject to various disturbances, the final chapter analyzed from hardware, software, anti-jamming aspects, and on this basis, designed the anti-jamming algorithm in software.In paper, the running results of the system show that the auto-tracking control based on solar power technology is feasible; the system design is completed with good results.
