This work reports about the latest application of a generic time-dependent real-time simulation tool, originally developed for fuel cell gas turbine hybrid systems, and now applied to an actual micro gas turbine test rig.The real-time modeling is a recognized approach to monitor advanced systems and to improve control capabilities: applications of real-time models are commonly used in the automotive and aircraft fields. The overall objective is the improvement of calculation time of existing time-dependent simulation models, retaining acceptable accuracy of the results. The real-time modeling approach already applied to fuel cell gas turbine system has been here validated against the experimental data of the micro gas turbine Turbec T100 test rig in Savona, Italy. The real-time model of the microturbine recuperator has been newly developed to fit such an application. Two representative transient operations have been selected for verification: the heating and cooling phases of the connected volume. Results show already an acceptable agreement with measurements, and they’ve contributed to a better insight in performance prediction of the entire plant.
