摘要
聚焦型太阳模拟器应用于光热发电相关试验,主要由风冷系统、光学系统、机械系统、控制系统组成。为了消除系统的人工安装误差、减小光斑调整误差,设计了基于STM32处理单元,结合PID算法,采用RS485通信标准,以液晶触摸屏为输入输出单元的太阳模拟器控制系统。该系统主要包括氙灯光强度控制、氙灯阴极温度控制、氙灯单元俯仰、平移控制等模块。通过对控制系统的搭建,实现了光斑面积与焦平面的位置调整,以及氙灯阴极温度的检测与控制,有效解决了多光源系统焦点光斑汇聚重合的问题。
Focus-type solar simulator, which is applied to solar thermal power generation-related test, mainly consists of air- cooled system, optical system, mechanical system and control system. In order to eliminate manual installation error of the system and reduce the spot adjustment error, a solar simulator control system is designed based on STM32 processing unit combi- ning with PID algorithm, adopting RS485 communication standard and using LCD touch screen for input and output units. The system includes modules of xenon light intensity control, xenon lamp cathode temperature control, xenon lamp unit＇s tilting and translation control. Through construction of the control system, the spot size and focal plane position adjustment, and the xen- on lamp cathode temperature measurement and control are achieved, which provides a effective solution to the focus spot overlap problem of converged multi-source systems.
