摘　　要：针对现有的光伏阵列模拟器存在的缺陷,提出了一种基于FPGA的数字式光伏阵列模拟器。该模拟器可以模拟不同拓扑结构的光伏阵列在局部温度及辐照度参数不均衡条件下的输出I/V特性。首先在Matlab/Simulink中建立了光伏阵列的仿真模型及基于模糊PID控制器硬开关电源电路的光伏阵列模拟器模型。之后搭建了基于System Generator的硬件在环仿真平台,对FPGA控制器进行了硬件在环设计及仿真验证,克服了单纯软件仿真的缺点,极大地减少了开发过程的时间。最后完成了光伏阵列模拟器的实验测试,结果证明该模拟器能够良好地再现现场环境中光伏阵列的输出特性。To overcome disadvantages of the existing photovoltaic（PV） array simulator, a new kind of FPGA controller for digital photovoltaic array simulator design was offered. This PV array simulator could simulate different topology structure PV array output characteristics under the conditions of local temperature and irradiance parameters. First, PV array model and PV array simulator model of switching power supply circuit based on fuzzy PID controller were built using Matlab/Simulink. Then Hardware-In-the-Loop Simulation（HILS） platform based on System Generator was built to verify the FPGA controller. This method overcame shortcomings of the pure software simulation and reduced the development time. According to the results of the final hardware test, the numerical PV simulator based on FPGA can simulate PV array I/V characteristic curve with good dynamic response.
