摘　　要：根据太阳能电池自动跟踪系统的工作原理,研究了一种基于西门子S7-200可编程序控制器(PLC)的太阳能电池自动跟踪实训系统。系统采用双轴跟踪,通过光学传感器采集模拟太阳光位置信息,控制两维运动机构,使太阳能电池板始终正对着模拟太阳光源,从而获得最大的太阳能,该系统能够满足高职院校光伏新能源专业学生的实训教学,也可应用于工程实际中。According to the working principle of solar cell auto-tracking system,a solar cell auto-tracking system based on Siemens S7-200 PLC was studied for student′s training. The bi-axial tracking system is adopted in this system. The optical sen-sors are used to collect the information of the sun position to control the 2D movement mechanism,which keeps the solar panels facing the sun to gain the maximum solar power. This system meets the training requirements for students in PV new energy ma-jor of vocational colleges,and can be applied to real engineering circumstances.
