摘　　要：为克服光伏组件5参数模型参数传统求解算法矩阵奇异化、参数漂移等弊端,文章提出一种新型的参数求解算法,通过开路点与短路点等式将待求参数缩减为3个,并依据短路点斜率等式组成适定方程组后,以牛顿法解得光伏组件5参数模型的特征参数。通过与传统算法求解结果相对比,验证了所提算法的有效性和准确性。This paper proposed a novel algorithm for solving the parameters of five-parameter of photovoltaic module.In order to overcome the disadvantages of the traditional algorithm Jacobian matrix singularity and parametric drifting problem of photovoltaic module five-parameter model,based on the open circuit and short circuit equations,solvable parameters dimensions will be reduced to three,and the well-posed equations including the basis of short-circuit point slope equation will be calculated by Newton-Raphson method achieving all characteristic parameters of the of the five-parameter model.Comparing the actual experimental data and other algorithm,analysis results show that the proposed algorithm has the characteristics of high precision.
