Robust Stabilization of a Steam Power Plant Oscillations

Abstract

the objective of this paper is to propose a new approach to robust stabilization of power system oscillations with unstable or lightly damped rotor modes taking into consideration the steam turbine and Governor response. A stabilizing robust controller using H∞ optimal control is designed for a steam turbine SMIB along with heffron phillip's K model. Also CPSS and FLC are designed for SMIB along with heffron phillip's K model. The simulation results show the best performance adjusts by robust H∞ control.
