摘　　要：以实际光伏I-V输出特性曲线为参照,将多段折线法与均值阶梯线段法相结合,可以更为精确地实现光伏电池I-V特性曲线的拟合。研究了光伏模拟器的系统结构,利用Matlab搭建了光伏模拟器的仿真模型,并通过仿真验证了光伏特性曲线拟合方法及光伏模拟器系统结构的正确性,同时依据仿真结果比较了两种光伏特性曲线拟合方法,证明了采用多段折线法与均值阶梯线段法相结合的拟合曲线具有更高的精度。Based on the actual photovohaic I-V output characteristic curve, a more accurate fitting of the I-V character eurve by combining the multi-paragraph dogleg method and mean ladder line method can be realized. The system structure of photovohaic simulator is studied, and a photovohaie simulator simulation model by using Matlab is also built. The simulation verifies the correctness of the photovohaic character curve fitting method and the PV simulator system. Based on the simulation results, the two kinds of PV character curve fitting methods arc also compared in order to prove that the fitting curve combining muhi-paragraph dogleg method with mean ladder line method has a higher precision.
