Dynamic analysis of extraordinary operations of molten salt central receiver
Abstract
In this paper, a model of a central receiver has been implemented in the dynamic simulation software ISAAC Dynamics (ID). The model is capable of simulating draining and filling procedures of the molten salt inside the pipes, in addition to standard procedures. The model is subjected to a set of tests and the results are compared to those obtained by DLR, providing a technical comparison of the tube model composing the receiver included in the software CSP library and an additional confirmation of the results provided by the model developed by DLR. The Institute of Solar Research of the German Aerospace Center is developing, in cooperation with General Electric, a dynamic model of a central receiver capable of simulating relevant dynamic processes, built with Modelica and Dymola. In particular, the DLR model can undertake draining and filling procedures of the receiver. It underwent a set of validation tests by means of CFD analysis and experimental data provided by GE. The results of the CFD analysis and of the Dymola model are compared in this article to those obtained by ISAAC Dynamics. In addition, a basic receiver system will be drained and filled showing some interesting results about these operations.
