摘要
为提高对光伏阵列的利用率,分析了一种基于最优梯度最大功率点跟踪(MPPT)控制的光伏水泵调速系统。根据光伏阵列的特性及最优梯度控制的方法,通过检测光伏阵列的输出电压、电流及单片机软件控制来实现MPPT。介绍了系统软件和硬件的设计,最后用给出的实验波形证明该方法能使系统稳定运行。
In order to improve the utilization of solar arrays, the optimal gradient based on maximum power point tracking（MPPT） of photovohaie （PV） pump speed eontrol system is analyzed.According to the characteristics of pho- tovoltaie arrays and optimal gradient control method, eurrent and MCU soft-ware control aehieve the MPPT by detect- ing the PV array output voltage.The system software and hardware design are introduced also,the experimental waveforms of the system are given, and the results proved that this method allows stable operation of the system.
