摘要
介绍一种基于DSP的光伏水泵变频控制系统。利用空间矢量PWM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。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。
This paper presents a PWM inverter based on DSP for PV pumping system. The means of space vector can compensate for the voltage of solar array dc bus dynamic. It can keep the flux of motor constant while the output voltage of the solar array varies widely. Simultaneously considering the operation characteristics of PV pumping system, a simple practical control method of solar array maximum power point tracking is produced, and the maximum power point tracking control of the system is realized stably and reliably.
