针对现有太阳能光伏发电装置能量转换效率较低的缺陷,设计了一种新型太阳能光伏发电系统——双轴自动跟踪发电系统。研制了光电传感器,分析了光电传感器的工作原理;设计了系统的信号处理及控制电路。该系统能使太阳电池板在晴天始终保持与太阳光线垂直,在夜晚、阴天或太阳光辐照度低于工作照度时自动关机。为了得到该系统的发电功率随时间和天气变化的情况,进行了实验研究,最终得到光伏发电功率随时间和天气变化的规律。
Aiming at the defects of low energy conversion efficiency of the existing solar photovoltaic power generation devices, a new type of solar photovoltaic power generation system - a dual-axis automatic tracking power generation system is designed. The photoelectric sensor was developed, the working principle of photoelectric sensor was analyzed, and the signal processing and control circuit of the system was designed. The system enables the solar panels to be kept perpendicular to the sun in clear weather and to shut down automatically at night, cloudy or sunlit irradiance below operating illumination. In order to get the power generation of the system changing with the time and the weather, experimental research has been carried out to get the law that the photovoltaic power generation changes with the time and the weather finally.
