摘要 光伏组件的功率测量与太阳模拟器I-V测试仪密切相关。为了满足光伏组件制造企业在产线上对I-V测试仪进行快速校准的需求,文中提出了一种基于标准光伏组件比较测量的校准方法,并进行了不确定度分析计算。测量时,将标准光伏组件放置在太阳模拟器有效工作面上并保持位置不变,再用数字信号采集装置分别对标准光伏组件的开路电压和短路电流进行测量,然后将测量结果与太阳模拟器I-V测试仪得到的数值进行比较,得到修正系数。该方法综合考虑了辐照度、温度、采样时间等因素。根据分析,开路电压校准结果的相对扩展不确定度为1.6%(k=2),短路电流校准结果的相对扩展不确定度为1.8%(k=2),该过程能够较好地保证光伏组件功率的准确测量。 Power measurement of Photovoltaic(PV) modules is closely related to solar simulator I-V tester. In order to meet the requirement of PV module manufacturing enterprises for solar simulator I-V tester calibration in production line, we propose a calibration method based on comparison of measuring the same standard PV module and calculated the calibration uncertainty. The correction factor is obtained by comparing the open-circuit voltage and short circuit current of the same standard PV module measured by the digital signal acquisition device with the results measured by solar simulator I-V tester. The standard PV module should be placed in the effective working place of the solar simulator and be kept in the same position. This method takes into account the irradiance, temperature, sampling time and other factors. According to the analysis, the relative expanded uncertainty of the open-circuit voltage calibration results is 1.6%( =2), and the relative expanded uncertainty of the short-circuit current calibration results is 1.8%( =2), which results in accurate measurement of the PV modules.
