| 英文摘要 |
| The paper considers the stability of a single-machine infinite bus (SMIB) power system which is disturbed
by random fluctuation of a SMIB’s mechanic power and power angle. And a stochastic nonlinear model is presented to
describe the transient process of the excitation adjustment of SMIB. Based on the Lyapunov stability criterion of a stochastic
nonlinear system and a technique, which has been named as Nonlinear Integral Backstepping, to design a stabilizer for such
a system, a novel excitation control law is proposed to suppress random disturbance and improve the system’s stabilization.
The results of simulation show the correctness and validity of the presented excitation controller to suppress the random
disturbance. |
