摘　　要：提出一种基于单相dq变换的光伏系统控制策略,通过将输出电压信号的dq变换值与参考信号的dq变换值进行比较来控制逆变器的输出,实现光伏系统的稳定输出;该策略在选取不同的参考值时能实现光伏系统在并网和独立两种模式下的良好运行。通过Matlab/Simulink建立完整的光伏系统模型,以Meteonorm软件提供的上海地区的气象数据为参考进行一天的仿真,实验结果证明了该控制策略的有效性。This paper proposes a control strategy for the PV system based on the single phase dq transformation. In this control strategy, the comparison between the value of output voltage after dq transformation and the value of reference voltage after dq transformation is used to control the inverter, and the PV system outputs a stable voltage. With different reference voltages, the PV system can run well both in the grid-connect mode and in the independent mode with this control strategy. This paper builds a PV system model in the Simulink environment of MATLAB. Based on the meteorological data of Shanghai which is provided by Meteonorm, a simulation of the operation for one day is made, and the results verify effectiven- ess of the proposed control strategy.
