摘　　要：为节能减排的需要,微电网开始进入人们的视野。通过MATLAB/Simulink软件搭建光伏电池模型、简化燃料电池模型以及柴油发电机模型等微电源的Simulink模型,并利用MATLAB自带的风机模型一起,构建简单的微电网模型。对严重故障情况下该微电网系统故障恢复能力和维持电能质量能力进行仿真试验,结果表明所建微电源及微电网模型都能较好模拟实际运行情况,为微电网的进一步研究提供了仿真平台。For the need of saving energy and reducing emissions, micro-grid entered people＇s field of vision. In this paper,several micro-power models, such as photovoltaic cell model, simplified fuel cell model and diesel generator model are built with MATLAB/Simulink sortware. With these models and wind turbine model in MATLAB,a simple micro-grid simulation platform is built. Simulations are carried out to study the capability of fault recovery and maintain power quality for the micro grid systems under the serious fault scenario. Simulation results show that the micro-power models and the micro-grid model built in this paper can simulate the actual system operation very well, and it provides simulation platform for further study of micro-grid.
