The start-up of the PS10 power plant in Seville; Spain; in 2007 marked the entrance of solar tower power plants into the commercial state. Questions about the right operational strategy; particularly during unsteady operation states; come to the fore; and therewith the need to carry out transient simulations of entire tower power plants including the heliostat field. Meeting this necessity; the presented simulation approach opens the way to transient full plant simulations of solar tower power plants. A detailed heliostat field model was linked to a dynamic receiver model by coupling both simulation tools. A second coupling was established to a tool hosting a control panel of the heliostat field model. With this simulation approach; a start-up procedure and a tracking stop were simulated delivering different transient behaviors of local absorber temperatures and mass flows.
