光伏发电的六象限法太阳自动跟踪系统

Six quadrant automatic tracking system of solar photovoltaic power generation

为了增加太阳能电池的输出功率,往往采用光伏板自动跟踪太阳的方法。文章在传统的四象限法跟踪基础上,设计了一种六象限法光电式太阳位置检测跟踪装置。采用STC12C5A60S2单片机作为控制芯片,以步进电机作为执行机构,通过单片机控制双步进电机,实现双轴太阳自动跟踪。实验表明,该系统不仅可以实现对太阳的自动跟踪,而且能提高对太阳跟踪的稳定性,具有较高的实用价值。

In order to increase the output power of solar cell,automatic tracking method is often used. On the basis of traditional four quadrants tracking method, a six quadrant photoelectric solar tracking device is designed in the paper. With the STC12C5A60S2 microcontroller as control chip and stepping motor as actuator,single-chip microcomputer controls two stepping motors to track the sun position automatically in dual-axis. Experimental results show that the system can not only realize the automatic tracking of the sun, but also can improve stability of the solar tracker, which has high practical value.
