Abstract: To enhance the transient stability of a synchronous generator, non-linear adaptive control of the governor is investigated based on modern non-linear adaptive techniques. A non-linear adaptive feedback governor controller is designed to play the role not only in damping the rotor angle oscillations but also in reaching the desired performance during post-temporary-fault or post-permanent-fault. The proposed controller can render the resulting closed-loop system to converge quickly to a stable equilibrium point, irrespective of the operating equilibrium point of the system and the fault sequence in transmission line. Some comparison results with the governor controllers obtained by existing design methods are given in simulation to demonstrate the effectiveness of the proposed control schemes.
