4测试要求

4.1待测试的槽式集热器宜配备支架、反射镜、集热管、驱动系统和就地控制器等部件，并按照说明书

要求正确安装。

4.2集热管、反射镜、驱动系统、支架等部件宜事先在条件允许的情况下采用现有的测试方法或测试标

准分别进行测试。

5测量仪器

5.1太阳能辐射测量

5.1.1太阳能辐射测量应按照ISO9806：2017中21.1规定执行。

5.1.2采用精度不低于±0.1°的太阳位置传感器测量或计算确定入射角。当根据太阳位置方程计算

时，计算算法的精度不应低于0.025°。

5.2流量测量

流量测量应按照ISO9806：2017中21.4.1的规定执行。

5.3温度测量

5.3.1温度测量（集热器进口温度、集热器出口温度和环境温度）应按照ISO9806：2017中21.3的规

定执行。

5.3.2集热器的进口和出口位置应根据集热器技术要求确定，应在距离上述位置不超过200mm处安

装温度传感器。

注：当传感器安装在聚光区域时，考虑聚光光线对传感器的影响。

5.4风速测量

水平面平均风速测量的不确定度应小于0.5m/s。传感器应安装在距离地面10m±0.1m高度

处。传感器应安装在距离集热器端部（如图A.1所示的边缘支撑立柱）不超过100m的位置。当在电

站气象站的前述距离范围内未设置风速传感器时，宜在集热器附近增设一台临时的风速传感器。

5.5数据采集

数据采集应符合ISO9806：2017中2
