摘要
针对光伏阵列输出功率具有非线性和时变性的特点,在PSCAD仿真软件中搭建了光伏发电系统模型,通过BOOST电路并采用扰动观察法实现MPPT控制。通过模型仿真,结果表明在外部环境参数变化时MPPT控制可以实现对于光伏阵列的最大输出功率进行快速、有效的跟踪,并且使其始终保持最大功率输出。
Through analyzing the characteristics of output power of the PV array such as nonlinear and time-varying,this paper establishes a simulation model of Photovoltaic power generation system on the PSCAD,and adopts the perturbation and observation method to achieve MPPT control through BOOST cir- cuit.By model simulation,the results show that when the external environment parameters ehange,MPPT control can be implemented quickly and effectively track for maximum output power of the PV array,and ensures that it is always maintaining the maximum power output.
