摘要
介绍一种高精度的光伏阵列区域特性模型。首先采用不同的算法模型对光伏阵列实测IV数据进行拟合,分析比较各种模型的精度水平。推广模型的适用范围,加入环境因素的影响,基于上述各种算法模型对光伏阵列区域特性进行预估研究。通过实验结果对照分析,得到满足工程应用精度要求的实用预估模型,此模型仅采用实测的Isc、Voc、Im、Vm作为参数,便可测得任意环境下的光伏阵列区域特性。光伏阵列区域特性模型及测试的研究能有效地评估光伏阵列的性能,为光伏系统设计需要提供依据,便于光伏系统的开发和利用。
The paper introduces a PV array characteristics model with high precision. It analyzes three different models for fitting the IV data of PV array by comparing their precision. Take ambient environment parameters into account to expand these models. A practical model possible to describe the PV array characteristics in ambient condition is established. This method has been tested on various PV array, and the accuracy of the model is sufficient for most practical engineering applications. The PV array Characteristics research helps to reflect the actual condition of the PV array.
