Summary:The short circuit caused by lightning stroke is one of the main causes of large disturbance in power system. In this paper, the propagation characteristics of electromechanical disturbance are analyzed in power systems. First, the zero transmission control and perturbation quenching control methods for electromechanical disturbance propagation in AC interconnected power grids are proposed based on superconducting magnetic energy storage (SMES). Subsequently, combined with lightning early warning system, the control strategy of electromechanical disturbance propagation in AC interconnected power grid under lightning stroke is obtained. Finally, the validity of the proposed control strategy is verified by PSCAD / EMTDC simulation.
