The invention relates to a wind power high-proportion power grid safety and stability control method, the method is applied to a safety and stability control system comprising a plurality of main stations and execution stations supporting information sharing, and the method comprises the following steps: acquiring specified wind power capacity information and power grid operation condition information reported by the execution stations; obtaining fault information according to the power grid operation condition information; according to the fault information and the specified wind power capacity information, obtaining a control command of wind power capacity needing to be switched off; and sending the control command of the to-be-switched-off wind power capacity. Through the embodiment ofthe invention, the information sharing of the master station and the execution station can be realized, the coordination control efficiency among regional power grids can be improved, and the difficulty of channel organization and the influence of communication channel abnormality on the operation of the stability control system can be reduced.
