摘 要
随着人类经济社会的发展,资源短缺已经成为人类共同面临的问题。为此,人们把目光投向了一种新能源---太阳能。太阳能是一种非常具有开发潜力的能源,世界各国都在积极开发利用太阳能。我国太阳能的利用,在近十年发展得非
常迅速,但是我国的太阳能利用技术还比较落后,且太阳能利用的局限性很大。 为了进一步扩大太阳能的利用范围,提高太阳能的利用率,本文开发了一套基于三菱PLC控制的太阳跟踪系统,该系统能够使太阳能利用装置时刻保持与太阳光线垂直,利用安装在太阳能电池组件的不同方位光敏传感器检测太阳与电池组件相对位置,检测结果传输给PLC,PLC通过变频器、伺服放大器分别驱动三相低速同步电机和伺服电机动作,实现水平角和俯仰角两轴控制。

ABSTRACT
With the rapid development of financial society, the shorty of resource becomes a common question human face. For it, People have found a new energy---Solar energy .Solar energy is a kind of energy with great potential development, and many countries is trying to utilize it. The use of solar energy is developed very fast in our country in recent ten years. But the technology of utilizing solar energy is still relatively backward, and the application of solar energy is restricted by many factors. To widen the use of solar energy and increase the utilization of solar energy, the solar energy tracking system in based on Mitsubishi PLC is designed in this paper. The system can guarantee that the device of utilizing solar energy is vertical to sun streams.Used to install the system in different position of the solar modules relative location of the sun and battery components, photosensitive sensor detection results transmitted to PLC, PLC by frequency converter, servo amplifier respectively drive three-phase low speed synchronous motor and servo motor movements, two axis horizontal Angle and pitching Angle control.
Keywords : PLC,Frequency Converter , Servo, Solar energy, tracking
