研究了基于太阳自动跟踪的独立光伏发电系统.太阳能光伏发电作为太阳能利用的重要方式,发展前景非常广阔.目前,光伏发电系统多采用固定安装的形式,这种发电系统具有发电效率低、成本高、不宜推广等缺点.在光伏发电系统中使用太阳自动跟踪能有效地提高太阳能的利用率.设计了一种基于无线网络的自动跟踪式光伏发电站监控系统,应用DSP芯片,调整安装在双轴旋转平台上的微型光伏传感器与太阳光的角度,获取太阳光的强度和角度的测量信息,通过Zigbee接口向系统中其它设备报告.实验证明,该系统具有耗能小、精度高等特点.%An stand-alone PV(photovoltaic) generation system based on automatic solar tracking was researched. As an important way of utilizing solar energy, PV power generation has a broad prospect. Now many PV power generation systems use fixed-mounted solar panels. These systems have the disadvantages of low efficiency of electricity generation, high costs and difficulty to promote. By using solar automatic tracking, PV power generation systems can effectively improve the utilization of solar energy. So the study of this paper has an important significance to improve the efficiency of PV power generation and promote its application. An automatic tracking type photovoltaic power plant control system based on wireless network was designed in the paper, and the angle between the sunlight and the micro-photovoltaic sensor which was installed in the two-axis rotating platform was adjusted with the application of DSP, the measurement information of the intensity and angle of the sunlight was obtained, and the results were sent to other devices in the system through the Zigbee interface .Proved by the experiment, it has a small energy consumption and high accuracy.
