摘要:

为满足聚焦型碟式太阳能光热发电对阳光跟踪的高精度要求,文中介绍了一种采用二维PSD传感器和硅光电池相结合的方法,实现了全方位的阳光跟踪,采用差值比例测量的硬软件措施克服了温漂的影响。同时避免了日历跟踪引起的计算误差,也节省了测量角度编码器的硬件成本,实用效果良好。

Abstract:

This paper introduces an approach to tracking the sun with the two-dimensional PSD sensors matching with silicon photocells to realize omni-directional highly precise sun tracking. The difference scale circuit eliminates the temperature drift error of PSD sensor. This method avoids the calculation error of calendar tracking and reduces the hardware costs of the encoders measuring the angles with good practical effect.

Key words: sun tracking, two dimensional PSD, silicon photocell
