A novel control strategy based on superconducting magnetic energy storage（SMES）to damp electromechanical disturbances is proposed.The electromechanical characteristic impedance which determines the propagation characteristics of electromechanical disturbances is described based on electromechanical wave theory;the electromechanical characteristic impedance is obtained by means of model based calculation and measurements based calculation，respectively.An electromechanical disturbance controller with different transmission coefficients based on SEMS is proposed.The proposed controller is tested on the WECC127-bus system using PSS/E，and the simulation results show that the disturbances will be confined within a certain area as the zero transmission controller or the electromechanical disturbance controller is realized according to the designed transmission coefficient.It is preliminarily proven that the electromechanical wave controller based on SMES is feasible and effective.
