摘　　要：针对难以利用实际光伏电池组成试验平台进行光伏系统研发的问题,设计并搭建了一种用于模拟光伏组件的半实物实验仿真平台。平台主要包括通用实时仿真器(UREP)、双核控制器以及由多组电压可控的IV象限变流器构成的物理装置。仿真器与Matlab/Simulink软件较好兼容,建模操作简易直观,模型可直接下载编译到仿真器运行,省去了烦琐的嵌入式开发过程。控制器采用双核技术,在发送控制信号的同时可对电压、电流采集信号进行实时反馈。通过对光伏组件伏安输出特性进行仿真模拟,初步验证了所提实验平台的可行性。该平台通用性和实时性良好,开放程度较高。A semi-physical simulation platform is designed and built to simulate real photovoltaic modules in order to address the difficulty of using real photovoltaic cells to form a test platform for photovoltaic system development.The platform mainly consists of a self-developed universal real-time emulator(UREP),a dual-core controller and a physical device consisting of several sets of voltage controlled four-quadrant converters.The simulator is perfectly compatible with MATLAB/Simulink software,making the modelling operation easy and intuitive,and the model can be downloaded and compiled directly into the simulator,eliminating the need for tedious embedded development processes.The controller uses dual-core technology to send real-time control signals while providing real-time feedback on the voltage and current acquisition signals.The feasibility of the proposed experimental platform is preliminarily verified by simulating the volt-ampere output characteristics of PV modules,which has good versatility and real-time performance,and is highly open.
