Abstract

The 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 con-
troller 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 pro-
posed 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.
