基于MPPT的太阳能照明控制器研究

Researches on solar illumination controller based on the MPPT

采用四组磷酸铁锂电池作为储能元器件,提出了一种带MPPT功能的智能太阳能照明控制方法.系统以ARM7LPC2103芯片为控制核心,对四组磷酸铁锂电池巡回智能充放电,并给出了其充放电的软件控制流程图.系统采用扰动观察法对太阳能电池板进行了最大功率跟踪,并且对其建模仿真,运行结果良好,最后对系统进行了调试.系统运行结果表明,该控制器比传统的控制器拥有更好的实用价值,利用率高.

Taking four sets of Lithium iron phosphate battery as energy storage devices,a intelligent solar illumination control with MPPT is designed.The controller uses the ARM7 chip LPC2103as core,control the batteries intelligent circuit charge and discharge.Perturbation and observation method are used to tracking the maximum power.Software control flow chart also been given and finally the system debugging.From the test,the controller is found to own better and value than the traditional ones.
