Abstract
In CSP technology,predicting and measuring the energy flow density distribution or concentration ratio distribution of the concentrated spot light of the concentrator is helpful for optimizing the design of the concentrator and is of great significance for improving the power generation efficiency of CSP.This paper proposes the use of moonlight to indirectly measure the concentration ratio distribution of a concentrator,which is more efficient and safe,due to the limitations of high temperature and high heat flux density in directly measuring the concentration spot energy flow density distribution of the concentrator through sunlight.Tracking moonlight through a disc condenser,capturing spot images using a CCD camera,evaluating spot clarity using Laplacian gradient function,and fitting samples using statistical models.The research results indicate that different phases of the moon have a significant positive impact on the clarity of the spotlight spot.The closer the moon phase is to the full moon,the higher the clarity of the spot.The research results can provide theoretical support for establishing the conversion relationship between the distribution of moonlight concentration ratio and the distribution of sunlight concentration ratio.关键词
