摘要
文介绍一种基于DSP具有光伏水泵控制功能的通用变频控制系统。利用空间电压矢量算法实现对光伏阵列母线电压动态补偿的功能,保证在光伏阵列工作电压大范围变化条件下,变频驱动电机满足恒磁通调速控制。再结合光伏水泵系统的工作特点,给出了两种简单的CVT和TMPPT最大功率点跟踪控制方式。实现了最大功率点跟踪控制及系统的可靠稳定运行。
This paper presents a general inverter based on DSP for photovoltaic pump system. Utilizing the function that compensates for the voltage of solar array dc bus dynamic by the means of space vector pulse width modulation to keep the flux of motor constant ,while the output voltage of the solar array varies widely. Considering the operation characteristics of photovoltaic pump system, two simple practical control methods of solar array maximum power point tracking is produced,that is CVT and TMPPT. The maximum power point tracking control of the system is realized stably and reliably.
