Abstract:Wide-area damping controller can effectively damp inter-area low-frequency oscillation. The resulting time delay has become an important factor affecting controller performance. Therefore, time delay and wind-up will affect the damping controller effect. The linearized model of power systems is established taking the unavoidable transmission time delay of the wide-area measurement signals and wind-up into consideration. A new type of anti-windup wide-area time-delay damping controller is designed based on parametric Lyapunov method. The test on the New England system confirmed the control effect of the controller proposed in this paper.
