摘　　要：针对大型并网光伏电站工程设计与仿真分析系统开发中,如何绘制光伏阵列单元运行特性曲线的实际问题,提出一种分段非线性插值算法。该算法以光伏组件性能参数为基础,计算得到5个光伏组件性能特征点,再结合光伏阵列的串并联方式,实现光伏电站阵列单元性能曲线的计算机生成。并以基于该算法开发的软件模块工程为例,说明该算法的应用情况。Based on the PV module performance parameters, five performance points of PV module were obtained by calculation. The curve of performance was generated by shape-preserving interpolation on the computer from the five points. The algorithm better describes the electrical characteristics of PV arrays performance curve, and can be used for the computer application software development of the photovohaic power generation system.
