摘　　要：设计了一种应用于塔式太阳能热发电聚光系统的具有自主供电和智能跟踪功能的定日镜.该定日镜采用小面积的反射镜面,具有高度角和方位角二维转动功能,并采用低功耗的微控制器实现对太阳实时有效地跟踪,基于无线技术实现定日镜控制器与中央服务器的无线通讯,采用太阳能光伏组件和可充电电池实现定日镜两轴电机的功率驱动和持续运转,并进一步优化定日镜的间歇式跟踪,以保证整个系统低功耗运行.通过设计分析和仿真验证,该系统能实现最大3 m2镜面的定日镜的自主式供电和智能跟踪.This paper proposed a small size heliostat that was self-powered and realized zenith-azimuth sun-tracking intelligently. It implemented the real-time and efficient track of the sun with the low-power microcontroller, and had wireless communication between the microcontroller and the central server based on wireless technology. The two-axis motors of heliostats achieved power-driving and sustainable operation with PV modules and rechargeable batteries. Moreover, the interval sun-tracking of the heliostat was optimized to guarantee the system operating in the low-power state. Through theoretical analysis and simulation, self-powered and intelligent-tracking properties of the maximum area heliostat with a mirror of 3 m^2 were validated.
