摘要
本文主要论述台达ES2 PLC在追日系统的应用。通过ES2特有的SPA指令,根据本地时区、本地经纬度、海拔高度等参数计算出追日系统的方位角及俯仰角,由PLC的输出点驱动电机执行追日动作,参数的设置及系统的运行状态由台达文本显示器实现。
This paper mainly studies the application of Delta products in PV solar tracker. According to the local time zone,the altitude,the local longitude and altitude,the user can calculate the azimuth angle and pitch angle by the SPA instructions.The PLC outputs drive the motor to complete the tracking motion.At the same time,the parameter settings and the system running status are displayed by Delta＇s Text Panel.
