摘　　要：该文提出了大规模光伏并网系统数字仿真模型,基于这一模型,在C++Builder开发环境下,开发出了相应的软件,并给出了仿真实列;计算结果表明:利用该软件和安装地点的气象数据以及光伏阵列的配置,可以计算光伏电站系统各部件的功率及分布,从而预测光伏并网系统的长期运行性能,如光伏阵列、逆变器和电网之间的匹配程度,系统的运行效率和成本等等。The paper presents models for numerical simulation of large-scale photovoltaic grid-connected systems （LPVGS）. On the basis of the models,corresponding software is developed in C＋＋ Builder development environment. A calculating example of LPVGS is provided. The results show that by the use of this software, the weather data in site and configuration of solar arrays, the operation power and its distribution of all components of the LPVGS can be calculated so that the long-term performance may be predicted, such as the matching degree among the photovoltaic（PV）array,the inverter and the utility, system efficiency, system cost and so on.
