Abstract

ABSTRACTThe article presents the dynamic analysis of split-shaft microturbine coupled with synchronous generator. Dynamic studies of microturbine generator (MTG) system are investigated considering both speed controller and load following controller. It is shown that speed controller is necessary for MTG system when there is a sudden increase or decrease of load demand with respect to the reference set point. A new load following controller with a frequency deviation as an input signal to it, is also proposed and eliminates the need of a speed controller for MTG system for variations of load demand. Finally MTG system is connected to an 11 kV rural distribution network to examine the transient behavior during active power injection. Simulation results for various cases are presented.
