摘　　要：分析了聚光太阳能发电系统中目前常用的程序跟踪法和传感器跟踪法的特点,阐述了程序跟踪和传感器跟踪相结合实现精确跟踪的原理,并介绍了相应的控制方法和模拟跟踪装置的组成。这种方法可以利用低成本的角度传感器和四象限光电池实现太阳光线的精确跟踪,有利于降低跟踪系统的硬件成本。跟踪装置运行结果与SPA算法的结果比较,实测的跟踪误差不大于0.03°,满足高聚光比太阳能发电系统对太阳跟踪的要求。The traits of the program tracking and sensor tracking methods used in current concentrated solar power system was analyzed. The principle of a tracking method based on a combination of the program tracking strategy and the sensor tracking strategy was described. The control method and the formation of the tracking simulator were also introduced. The method introduced is able to follow the sun＇ s rays with high accuracy. It is also in favor of keeping down the cost of the hardware. The experimental results suggest that the tracking error of the device is less than 0.03° compared with the SPA algorithm, meeting the sun tracking requirement of the high-concentration solar power system.
