摘　　要：介绍一种基于空间矢量PWM控制的光伏水泵变频控制系统。该空间矢量PWM算法具有对光伏阵列母线电压的动态补偿功能,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。同时结合光伏水泵系统的工作特点,提出了一种简单实用的光伏阵列最大功率点跟踪控制方式,稳定可靠地实现了系统的最大功率点跟踪控制。A PWM inverter based on space vector for PV pumping system was presented.The voltage of solar array dc bus can be compensated dynamically,to keep the flux of the motor constant while the output voltage of the solar array varies between wide scale.A simple practical control method of solar array maximum power point tracking was performed considering the operation characteristics of PV pumping system,so that the maximum power point tracking control of the system is realized stability and reliably.
