摘要

提出一种塔式光热电站吸热器表面组合光斑能流密度检测方法

通过CCD相机拍摄镜场内部分定日镜在漫反射标靶上的光斑样本

映射出全镜场所有定日镜投射在吸热器表面的光斑能流密度分布

实现吸热器表面组合光斑能流密度的测量。该方法结合了间接测量法和数值模拟方法各自的优势。详细介绍该方法的原理

并在青海省某50 MW塔式光热电站进行测试实验

结果证明：该方法能够定位组合光斑能流密度发生偏差的区域

在典型时刻

测得的组合光斑和设计值对比

80%的吸热器面板均值能流密度偏差在5%以内

偏差较大的面板集中在南侧

最大均值偏差12.9%

最大峰值偏差18.9%。对产生偏差的定日镜群进行调整后

可降低吸热器能量溢出损失约1个百分点。

Abstract

A method for measuring the concentrated spot flux distribution on the receiver in a solar power tower plant is proposed. The spot samples of some heliostats on the diffuse reflection target are photographed by the CCD cameras

and the flux distribution of the spots on the receiver surface reflected from the heliostats in the whole solar field is mapped

so as to realize the measurement of the flux distribution of the concentrated spot on the receiver. The method combines the advantages of indirect measurement method and numerical simulation. The principle of the method is introduced in detail

and the test is carried out in a 50 MW solar power tower plant in Qinghai Province

which verifies the feasibility of the method. The experimental results indicate that the method can locate the area where the flux of the concentrated spot deviates. A typical measured concentrated spot is compared with the design value. 80% of the receiver panels have an average flux density deviation less than 5%

and most of the panels with large deviations are on the south side. The maximum average deviation is 12.9%

and the maximum peak deviation is 18.9%. The energy spill loss is expected to reduce about 1% after adjusting the heliostats that produces deviation.
