摘要
以目前应用最为广泛的光伏阵列工程数学模型为基础,推导出一种新型工程数学模型——光伏阵列幂函数模型,并将其应用于光伏阵列模拟器的设计。模拟器控制环节利用IPC完成系统的数据分析处理以及实时控制,实现了模拟光伏阵列在光强、温度动态变化中的对外输出,并可以实时显示光伏阵列I-U特性曲线。测试结果表明,该模拟器可以根据负载等效阻抗的变化快速调节输出,使负载工作点迅速稳定在光伏阵列I-U特性曲线上,动态响应良好。
Based on the most popular photovohaic array engineering mathematical model, a photovohaic array power function model, which is a new type of mathematics model, is deduced, and it has been applied to the design of PV array simulator. The simulator control unit complete data analysis, processing and real-time control by IPC. Photovohaic array output is simulated when light intensity and temperature change, and photovohaic array characteristic curve can be real-time display. The test resuhs show that the simulator can adjust output rapidly to track photovohaic array I- U characteristic curve according to load equivalent impedance changes, performs a good dynamic response, and plays a very good reference function for the research of PV array simulator.
