欧洲一些测试中心,如ESTEC(欧洲空间技术中心,荷兰)、IABG(工业设备管理中心,德国)和INTESPACE(空间环境工程试验中心,法国)采用不同方法描述太阳模拟器特性。本文对这些方法进行比较与评定,对总辐照度与光束均匀度的各种测量方法进行验证,保证用户采用相同的标准对测试数据进行评估与解释。为了在太阳模拟器性能测量中能够采用适当的术语,对有关国际标准进行了调查,并将它们汇编成一个文件,以便在总辐照度和光束均匀度测量中使用。业已确定了一种国际标准作为绝对总辐照度的顶级参考标准,所有工作标准都对照它来标定。本文汇总了这几个测试中心描述太阳模拟器热特性的方法,对比了这些测试方法所采用的结构、试验体积和性能参数。讨论了测量与控制总辐照度参数的不同方法以及手动控制系统和闭环控制系统。就光束均匀度测量而言,这些测试中心采用了两种不同原理的扫描方法,即笛卡尔坐标法与极坐标法。为了比较现有的均匀度曲线,必须考虑数据采集、转换与处理的方法。因此,根据采集的三维综合数据集用计算机仿真来对不同方法进行分析评估。本文给出的结果可对光束均匀度进行比较,且数据评估对用户透明。结果概括在一个太阳模拟器标定程序之中。考虑到不同测试中心使用的设备与仪器各不相同,这份文件只涵盖这些协调测试中心测量总辐照度与光束均匀度的最起码的通用要求。
Several European test centers such as ESTEC (European Space Technology Center, Netherlands), IABG (Industrial Equipment Management Center, Germany) and INTESPACE (Space Environmental Engineering and Testing Center, France) use different methods to characterize the solar simulator. In this paper, these methods are compared and assessed, the total irradiance and beam uniformity of various measurement methods to verify, to ensure that users use the same standard test data to evaluate and explain. In order to be able to use the appropriate terminology in solar simulator performance measurements, relevant international standards were investigated and compiled into a single file for use in total irradiance and beam uniformity measurements. An international standard has been identified as the top reference standard for absolute total irradiance, against which all working standards are calibrated. This article summarizes the methods used by these test centers to describe the thermal characteristics of solar simulators, and compares the structure, test volume, and performance parameters used in these test methods. Different methods of measuring and controlling the total irradiance parameters, as well as manual control systems and closed-loop control systems, are discussed. For beam uniformity measurements, these test centers employ two different methods of scanning, the Cartesian and polar methods. In order to compare the existing uniformity curve, we must consider the data acquisition, conversion and processing methods. Therefore, different methods are analyzed and evaluated based on the collected 3D integrated data sets using computer simulation. The results presented in this article allow a comparison of beam uniformity and the data evaluation is transparent to the user. The results are summarized in a solar simulator calibration procedure. Considering the different equipment and instruments used in different test centers, this document covers only the minimum general requirements for these test centers to measure total irradiance and beam uniformity.
