A micro-turbine model for system studies incorporating validated thermodynamic data

There is an apparent lack of micro-turbine dynamic models available in literature that include valid experimental data. In an effort to help fill this gap a thermodynamic based micro-turbine model supplemented with experimental data & validated calculations is introduced. The data was extracted from a study on the 60 kW Capstone C60 MicroTurbine™. Transfer functions describing the micro-turbine model valid for various types of studies are defined; namely EMTP studies, controller design, small signal and stability analyses. Simulations are performed in PSCAD/EMTDC to validate the derived transfer functions, and to investigate the micro-turbine transient response. Researchers can utilise this calibrated model within their power system studies to quantify the application of micro-turbines as distributed generating sources within the distribution network.
