摘要
通过对光伏电池的数学模型和电流电压曲线的分析,提出了光伏电池最大功率线的跟踪方法。采用与光伏电池性能相同的光伏传感器,控制逆变器工作电流的大小,当光强或工作温度发生变化时,对跟踪系统都无影响,从而实现最大功率点的可靠跟踪。该方法不需复杂的分析与控制,原理较简单,具有一定的市场前景。
The method of tracking photovoltaic maximum power is put forward by analyzing the math model of photovoltaic cell and the relationship of current voltage.The running current of the inverter is controlled by photovoltaic transducer which has the same properties with photovoltaic cell.It has no effect on the tracking system while illumination or temperature change then the reliably tracking of maximum power is achieved.There is no need of complicated analysis and control.The principle is simple and the methord has certain market prospects.
