摘　　要：光伏发电作为一种清洁能源,应用越来越广泛,但光伏电源发出的电能受到温度和光照强度的影响波动较大,需要与储能系统、DC/DC变换器配合使用以稳定输出、满足负载需求。采用全桥LLC谐振变换器对光伏单元输出电压进行调制,通过各单元的设计和相应控制策略的实施,基于dSPACE仿真实验环境,应用MATLAB搭建了基于光伏-储能系统的LLC变换器仿真系统,开发LLC谐振变换器构建实验系统,利用平台系统的仿真实验优势,提高学生结合实际工程问题进行仿真与实验研究分析的能力。As a kind of clean energy,photovoltaic power generation is more and more widely used.However,the power generated by photovoltaic power supply fluctuates greatly due to the influence of temperature and light intensity.It needs to be used with energy storage system and DC/DC converter to stabilize the output and meet the load demand.The full bridge LLC resonant converter is used to modulate the output voltage of the photovoltaic unit.Through the design of each unit and the implementation of the corresponding control strategy,based on dSPACE simulation experimental environment,the LLC converter simulation system based on the photovoltaic energy storage system is built by using MATLAB,and the LLC resonant converter experimental system is developed.The advantage of simulation experiment platform system is used to improve students ability of simulation and experimental research and analysis combined with practical engineering problems.
