Abstract

Flux density measurement on external receivers is an important parameter for supervision and control of commercial and research solar tower power plants. This article presents a flux density measurement system developed for open volumetric receivers that can be adapted to other receiver systems. Affordable video camera technique is used and advanced corrections are applied. Main focus is put on the challenge caused by not perfectly diffuse reflecting receiver surfaces and correction of this effect to achieve reliable measurement data. For this task the bidirectional reflectance distribution function of the used absorber material has been determined and employed. The system has been developed and tested by the German Aerospace Center (DLR) at the Plataforma Solar de Almería and the Solar Tower Jülich.
