Abstract:
Distributed generation (DG) is an era in current
electric market for providing a reliable power into the
distribution network. Microturbine generation system
(MTG) is one important source of DG due to its
conversion efficiency, reliability and power quality.
This paper introduces a long term dynamics model of MTG
system including the turbo generator with special
attention for combined gas steam power plant. The gas
turbine model is devoted to large rated microturbine
whose fluid mechanical time response is larger than
fluid gas in compressor, combustor and turbine chamber.
The system uses a permanent magnet synchronous machine
(PMSM) to convert mechanical to electrical power and
passive rectifier. The inverter uses a active and
reactive power (PQ), Voltage and frequency (Vf) control
strategies for the respective grid connected and
isolated mode of operation. The hybrid model of MTG
system has been developed in Matlab/Simulink
environment. The simulation result shows the load
compensation performance of long term MTG based DG
system in utility connected mode.
