| 摘 要： | 光伏水泵系统具有无污染、全自动等优点,且应用的场合较多,为此设计了一种以TMS320F28335为主控制器的光伏水泵控制系统。控制系统中的三相异步电机调速部分采用基于空间矢量脉宽调制(SVPWM)方式的变压变频(VVVF)控制,最大功率点跟踪部分采用恒定电压法(CVT)和扰动观察法结合最大功率点跟踪(MPPT)技术。试验结果表明系统实现最大功率点跟踪并稳定运行。

| Abstract: | The Photovoltaic (PV) pump system possesses advantages such as pollutionfree and fullyautomatic, which can be applied in a wide area. Thus a PV pump control system based on TMS320F28335 has been designed. The variable voltage variable frequency (VVVF) strategy based on space vector pulse width modulation (SVPWM) was employed in the speed governor of the threephaseasynchronous motor in the system. The MPPT algorithm took advantage of a combination of continuously variable transmission (CVT) and perturbation & observation (P&O) method. The proposed idea has been validated through experiment. |
