A New Nonlinear Excitation Control Strategy with Terminal Voltage Feedback

Abstract:

This paper presents a new nonlinear excitation controller for transient stability with voltage feedback of a synchronous power generator connected to a single machine infinite bus. In this design terminal voltage is introduced as a feedback. The proposed controller based on voltage feedback technique which enhance the transient stability of power system and stabilizes the terminal voltage about the given operating point when the fault occurs closer to the infinite bus bar. Simulation results show that, compared with the controller without voltage feedback, the proposed controller has better control effect on power system and which remarkably improves the deficiencies in the control of generator terminal voltage of the traditional control.
