摘要
针对传统光热发电方式效率低、规模小、成本高等问题,设计了塔式太阳能热发电站定日镜追踪控制系统。在这一系统中,现地控制器根据太阳位置算法、空间转换模型计算出镜面角度的理论值,并结合光束界定系统与镜场管理系统纠偏,驱动伺服电机完成镜面俯仰角、旋转角的调整,实现定日镜的跟踪控制。试验结果表明,应用这一系统,定日镜反射太阳光斑的精度高,符合运行要求。
Aiming at the weakness of traditional solar thermal power generation, such as low efficiency, small scale and high cost, the heliostat tracking control system of tower-type solar thermal power station was designed.In this system, the local controller calculates the theoretical value of the mirror angle according to the solar position algorithm and the space conversion model, and combines the beam definition system and the mirror field management system to correct the deviation, and drives the servo motor to complete the adjustments of pitching angle and the rotation angle of the mirror plane, so that the tracking control of heliostats is realized.The test results show that with this system, the heliostat can reflect the solar spot in high accuracy and meet the operating requirement.
