摘　　要：光伏模块依靠光伏逆变器将产生的直流电转变为交流电用于负载供电,光伏逆变器的设计需要考虑光伏模块的电气特性。根据光伏电池物理机制的数学模型,采用PSIM软件中已有的器件搭建光伏模块仿真模型。利用该仿真模型,通过PSIM软件模拟实际光伏模块在不同太阳光照强度、环境温度下的I-V和P-V特性。通过仿真分析串联电阻Rs和并联电阻Rsh变化对模块输出特性的影响,更加深入地了解光伏模块的电气特性。模型为将来光伏逆变器设计时的动态仿真研究提供了一个准确的仿真电源。DC from photovoltaic（PV） module is converted into AC to supply load through the PV inverter,the electrical characteristics of PV module need to be considered in the design of PV inverter.According to the mathematic model based on physics mechanism of PV cell,the simulation model of PV module is constructed with the element in the PSIM library.Using the simulation model,I-V and P-V characteristics of actual PV module are simulated in different light intensity and ambient temperature by PSIM.Through the simulation,the effect of the series and parallel resistances on the output characteristics of PV module is analyzed,and the electrical characteristics of PV module are acquired more clearly.The model has provided an accurate simulation power source for dynamic simulation study of PV inverter design.
