摘 要 太阳能（Solar Energy），一般是指太的辐射能量。自地球形成生物就主要以太阳提供的热和光生存, 后者是开环的程控系统。同时对两种太阳跟踪方式进行理论分析。 本课题设计的自动跟踪式太阳能光伏发电系统，实现了对太阳的自动跟踪，使太阳能电池板基本对准太阳垂直入射的方向，并实现了连续稳定的电能输出，保证用电负载的正常工作。 关键词： 光伏发电 自动跟踪 发电效率 太阳能 Abstract Solar Energy generally refers to the solar radiation energy. In the modern commonly used for power generation. Since the formation of the earth organism mainly to light and heat provided by the sun live. As the earth limited energy by continuous mining. One of the biggest problems facing the world today is that the energy crisis. Petroleum energy, carbon energy, ocean energy and other finite energy is reducing unceasingly, also brought the environmental pollution. To solve these problems is the way of the development and utilization of new energy without pollution. However, solar PV power station low efficiency, higher cost, directly restricts the photovoltaic industry, large-scale promotion, improve the efficiency of solar photovoltaic power station has become the basic requirements of photovoltaic industry. The design is aimed at how to improve the efficiency of solar power generation problem, puts forward the method of automatic tracking, automatic tracking system to the sun to make real-time judgments of the motion trajectory, thus making the solar panels in real time and sunlight perpendicular, improve the efficiency of solar power. Sun tracking method can be summarized into two ways, photoelectric tracking and trajectory tracking based on visual day. The former is the closed loop of stochastic systems. The latter is an open loop control system. At the same time to two kinds of solar tracking mode in theory analysis. This topic is to design the automatic tracking solar photovoltaic power generation system, to achieve automatic tracking sun, so that the solar panel is substantially aligned perpendicular to the sun incident direction, and realize continuous and stable power output, to ensure the normal work of electric power load.
