Modelling of Microturbine systems

Haugwitz, Staffan LU (2003) In Proceedings of the European Control Conference ECC03
Abstract
The paper describes the development of a dynamic model of amicroturbine system. The paper was done in close cooperation with the gas turbine manufacturer Turbec AB and the model was tuned and verified against theirmicroturbine system T100. The microturbine unit consists of a compressor and a turbine connected on a single shaft to a high-speed generator.The model includes all the main thermodynamic and mechanical components of the microturbine.Possible applications for the model are development of control strategies, dynamic performance verification, operator training and controlsoftware/hardware verification. Theemphasis has been on the functionality and accuracy of thesystem model and not of the component models. The modelis written in... (More)

Theemphasis has been on the functionality and accuracy of thesystem model and not of the component models. The modelis written in the Modelica modelling language and uses, when available, components from the standard libraries or from previous work as Tummescheitand Perez. Steady-state verificationhas been done with good results. When the microturbine runsat full load of 100 kW, there is an average error of 0.6 % for the 13 most important thermodynamic variables compared to reference values. Dynamic verification in three differentexperiments has been done and the model shows a good fitto the measured data from the real microturbine. (Less)
