摘要
设计了一种太阳自动跟踪光伏发电装置,可以运行在传感器控制和时间控制模式下,在气象条件好时采用光控模式,在多云天气采用时控模式,根据不同时刻确定双轴追日支架的倾角和东西旋转角度,保证光伏组件始终垂直太阳,达到最大发电功率。主要进行了控制系统的硬件和软件的设计。经过实验验证,双轴追日光伏发电系统的发电效率较传统固定角度的发电系统的发电效率高30%左右。
A solar automatic tracking photovoltaic power generation device is designed,which can run under sensor control and time control mode,light control mode in good weather conditions,time control mode in cloudy weather.The inclination angle and east-west rotation angle of the two-axis sun-pursuing bracket are determined according to different times,so as to ensure that the photovoltaic module is always vertical to the sun and achieve maximum power generation.The hardware and software of the control system are designed.The experimental results show that the power generation efficiency of the two-axis sun-tracing photovoltaic system is about 30%higher than that of the traditional fixed-angle power generation system.
