摘要：
In order to study the effect of collector shape and surface slope error on the efficiency of photothermal conversion in the parabolic dish concentrated solar power (CSP) system, the Monte Carlo ray tracing method was used to conduct related numerical simulation with four types of collectors and four surface slope errors. The results show that when the size of the focal plane is constant, the flux concentrating ratio is basically the same, and the heat flux on the focal plane presents the annular temperature distribution. The influence of condenser surface slope error on system heat radiation was also studied. Corresponding research results have provided theoretical reference for the design and actual performance prediction of parabolic dish CSP system. Copyright © 2018, AIDIC Servizi S.r.l.
