Abstract :
With coordinated passivation techniques, the dual-excited and steam-valving control for synchronous generators is proposed to achieve rotor angle and voltage stability. Steam-valving controller is designed by backstepping techniques, whereas dual-excited controller is based on coordinated passivation. The passivity-based control can be obtained to ensure that the closed-loop system is asymptotically stable. Simulations have showed the effectiveness of the control designs.
