Abstract
Steam turbine generator is an electromechanical system which converts
heat energy to electrical energy.
In this paper, the modeling, design and analysis of a simple steam
turbine generator have done using
Matlab/Simulink Toolbox. The open loop system have been analyzed to
have an efficiency of 76.92 %. Observer
based & linear quadratic regulator (LQR) controllers have been designed
to improve the generating voltage.
Comparison of this two proposed controllers have been done for increasing
the performance improvement to
generate a 220 Dc volt. The simulation result shows that the steam
turbine generator with observer based controller
has a small percentage overshoot with minimum settling time than the
steam turbine generator with LQR controller
and the open loop system. Finally, the steam turbine generator with
observer based controller shows better
improvement in performance than the steam turbine generator with LQR
controller.
