Abstract This paper proposes a generalized methodology to calculate the parameters of the single-diode or double-diode models of a photovoltaic module. The presented method relies in the solution by a simple iterative process of the set of equations obtained from the photovoltaic-module’s equivalent circuit. The use of the generalized form of Tellegen’s theorem allows the solving of the equivalent circuit’s equations in an exact way, without making considerations or approximations commonly used in previous works. The parameters of the equivalent circuit are obtained from the standard conditions of: open-circuit, short-circuit and maximum power, provided by the manufacturer in the data sheet of the photovoltaic module. The presented method is applied to obtain the models of several commercial modules. The accuracy of the obtained parameters is greater than that of the results previously determined by other authors. The curves calculated with the obtained models matches the experimental curves supplied in the manufacturer’s data.

使用特勒根定理确定光伏组件模型

摘要 本文提出了一种计算光伏组件单二极管或双二极管模型参数的通用方法。所提出的方法依赖于通过从光伏模块的等效电路获得的方程组的简单迭代过程来求解。特勒根定理的广义形式的使用允许以精确的方式求解等效电路的方程,而无需考虑以前工作中常用的考虑或近似值。等效电路的参数是从光伏组件数据表中厂商提供的开路、短路和最大功率的标准条件中得到的。所提出的方法被应用于获得几个商业模块的模型。获得的参数的准确性高于其他作者先前确定的结果。使用获得的模型计算的曲线与制造商数据中提供的实验曲线相匹配。
