基于PLC的太阳能光伏聚光发电随动系统的研究

Research on PLC-based solar PV condenser with tracking system

太阳能随动系统的追踪策略采用粗追踪和精确追踪两种相结合的模式.将全年每半个月的太阳理论位置为标准值,通过可编程序控制器查表的方式实现对太阳光线方位角与高度角的粗追踪;再采用导纳增量法实现对光伏聚光系统的输出最大功率点的精确追踪;同时也对光强智能传感器硬件合理设计以及电机拖动模块进行了探讨,使得系统具有较高的追踪精度和发电效率等诸多优点.

Solar dynamic system with the tracking strategy using coarse tracking and precise tracking of two combination mode.The annual every half month solar theory position as the standard value,through a programmable controller look-up table method to achieve the rays of the sun azimuth and elevation angle of the coarse tracking;then the incremental conductance method for photovoltaic concentrator system output maximum power point tracking precision;and also on the intensity of the hardware design of intelligent sensor as well as the motor drive module are discussed,the system has a high tracking precision and power efficiency and many other advantages.
