摘要

Abstract

This paper proposes a switching structure excitation controller (SSEC) to enhance the transient stability of multimachine power systems. The SSEC switches between a bang-bang funnel excitation controller (BFEC) and a conventional excitation controller (CEC)

based on an appropriately designed state-dependent switching strategy. Only the tracking error of rotor angle is required to realize the BFEC in a bang-bang manner with two control values. If the feasibility assumptions of the BFEC are satisfied

the tracking error of rotor angle can be regulated within the predefined error funnels. The power system having the SSEC installed can achieve faster convergence performance compared to that having the CEC implemented only. Simulation studies are carried out in the New England 10-generator 39-bus power system. The control performance of the SSEC is evaluated in the cases that three-phase-to-ground fault and transmission line outage occur in the power system

respectively.
