EXPERIMENTAL VERIFICATION OF CALCULATION MODEL OF CIGS AND HIT ARRAY FOR STRATOSPHERIC AIRSHIP

在进行平流层飞艇光伏能源系统光伏阵列输出功率仿真计算时,需对光伏阵列电性能输出进行准确建模。该文基于平流层飞艇光伏能源系统所用CIGS和HIT光伏阵列的特点,通过引入Lambert W函数理论对太阳电池的精确数学模型进行解耦计算,确定出光伏阵列在标准条件下的性能参数,进而得出计算光伏阵列在任意工况下电性能输出的模型。在此基础上,设计验证试验,将模型计算结果与试验结果进行对比分析。结果显示,模型计算误差≤3%,满足工程应用需求。为平流层飞艇光伏能源系统光伏阵列的设计计算奠定基础。

In the simulating calculation of the PV array output power of the stratospheric airship photovoltaic energy system,it is necessary to accurately model the solar array performance.Based on the characteristics of the CIGS and HIT PV array components used in the stratospheric airship photovoltaic energy system,this paper introduces the Lambert W function theory to decouple the accurate mathematical model of the PV array,determines the performance parameters of the PV array under standard conditions,and then obtains the calculated model of PV array electrical performance output under any operating conditions.On this basis,the design verification test is carried out to compare the model calculation results with the test results.The results show that the model calculation accuracy is not more than 3%,which meets the engineering application requirements.The research in this paper lays theoretical foundation for the design and calculation of the PV array of the stratospheric airship photovoltaic energy system.
