一种光伏发电双轴跟踪系统
摘要：
本发明涉及一种光伏发电双轴跟踪系统，属于光伏发电技术领域，所述的光伏发电双轴跟踪系统包括太阳轨迹跟踪系统和光电跟踪系统；太阳轨迹跟踪系统通过时钟模块向单片机Ⅰ提供时间参数，单片机Ⅰ发出偏转指令给驱动装置，实现太阳能电池板的角度调节，角度编码器给出太阳能电池板实际位置，并负反馈给单片机Ⅰ；光电跟踪系统通过光电二极管检测光强偏差信号，经过信号放大电路，再经A/D转换器后传输给单片机Ⅱ，单片机Ⅱ输出控制指令给驱动装置，实现太阳能电池板的角度调节。本发明采用太阳轨迹跟踪和光电跟踪相结合的方式，确保太阳能电池板和太阳垂直照射，与固定支架光伏发电系统相比，发电效率提高30%—40%。
摘要（英）：

The invention relates to a photovoltaic power generation double-axis tracking system, and belongs to the technical field of photovoltaic power generation. The photovoltaic power generation double-axis tracking system comprises a sun trajectory tracking system and a photoelectric tracking system; the sun trajectory tracking system provides a time parameter to a singlechip I via a clock module, the singlechip I sends a deflecting instruction to a driving device to adjust the angle of a solar cell panel, and an angle coder gives the actual position of the solar cell panel and provides negative feedback to the singlechip I; the photoelectric tracking system detects a light intensity deviation signal via a photoelectric diode, the signal is processed by a signal amplifying circuit and an A/D converter and then transmitted to a singlechip II, and the singlechip II outputs a control instruction to the driving device to adjust the angle of the solar cell panel. By combining sun trajectory tracking with photoelectric tracking, vertical irradiation from the sun to the solar cell panel is ensured; and compared with a fixed support photovoltaic power generation system, the photovoltaic power generation double-axis tracking system has the advantage that the power generation efficiency is improved by 30-40%.
