| Abstract: | The stability of power system is greatly influenced by the operation of excitation system、steam valving control system and FACTS controllers(such as: TCSC/SVC).In order to improve the stability of power system,a novel coordinated conroller used in a single machine infinite system is proposed for Steam-turbine Generator excitation、steam valving and FACTS(TCSC/SVC) in this paper The muti-output and input nonlinear mathematic modeling,which includes nonlinear FACTS,SVC,excitation and steam valving,is exactly linearized via state feedback.And the quasi-linearized system is controlled by sliding model control mathod.Simulation results show that the novel coordinated controller gives better dynamic response and stronger robustness. |
