【摘要】 光伏水泵系统是直接利用太阳电池光生伏打效应发电,之后通过一系列电力电子、电机、水机等控制及执行环节从而在江河湖泊或深井中实现提水的系统。该系统是光、机、电、控制技术等多学科交叉、结合的体现。着重对光伏水泵系统的构成、驱动方式、太阳电池阵列的最大功率跟踪及优化控制等方面做了分析和研究,并对光伏水泵系统的应用及控制的发展方向作出了展望。更多还原

【Abstract】 PV pumping system generates electricity directly by photovoltaic effect of solar cell.This system can realize water pumping from rivers and lakes or deep wells via a series of control and execution,including power electronics,electric machinery,pumps etc.This system is interacted and combined with light,machine,electric,control technology and so on.This paper emphatically conducts analyses and studies in respects of the structure of PV pumping system,driving mode,maximum power point tracking of solar array and its optimal control.Also it forecasts the application of PV pumping system and the development trend of its control.更多还原
