摘要
设计者根据光伏电源的数学模型,建立了光伏电源仿真模型。为了提高光伏阵列的利用效率,文章针对三相光伏发电并网系统,从PQ控制原理入手,在dq坐标系下建立了仿真模型,通过仿真得出PQ控制下的三相光伏发电并网运行特性,并建立小信号数学模型,通过建立小信号模型证明了仿真模型的正确性和有效性。
According to the mathematical model of photovoltaic power supply, the simulation model of photovoltaic power supply is established. In order to improve the utilization efficiency of photovoltaic array, this paper focuses on the three-phase photovoltaic grid connected system, this paper start with the PQ control principle, a simulation model is established in the dq coordinate system, through simulation, the operation characteristics of three-phase photovoltaic grid＇ connected generation under PQ control are obtained. The small signal model is established, and the correctness and validity of the simulation model are proved by building small signal model.
