摘要：

为提高跟踪式聚光光伏系统的发电效率,设计了一种基于ARM的太阳自动跟踪控制系统。系统采用视日运动与四象限传感器反馈相结合的太阳方向判断方法,同时增加了独立的光强传感器以确定是否启用跟踪系统(如阴天、雨天);论述了跟踪控制系统的机械结构及软硬件电路设计。测试结果表明,该跟踪系统功耗低、性能可靠且控制精度高(±1.5°),并可实现高精度跟踪太阳,满足了聚光光伏发电控制要求。

Abstract:

To improve the generating efficiency of tracking concentrating photovoltaic system,a sun tracking control system is designed based on ARM.The system tracks the sun by the method combining the sun tracking movement and four-quadrant sensor.The control system acquires the light intensity of an independent light intensity sensor to decide whether or not to start the tracking system (e.g.cloudy or rainy day).The mechanical structure of the tracking control system,hardware circuit design and software design are elaborated.Experiment indicates that this tracking control system has the advantages of low-power,reliable performance,and high tracking accuracy within ±1.5°.It can realize high precision tracking of the sun and satisfy the requirement of concentrate photovoltaic generating control system.

Key words: automatic tracking;low-power ARM;sun tracking movement method;independent light intensity sensor
