The invention discloses a method for a converter station reactive power compensation device to participate in power grid voltage control after direct-current locking. The technical scheme of the invention comprises the steps of 1, calculating a system equivalent reactance at a direct-current drop point converter station according to a direct-current system short-circuit ratio; 2, calculating sensitivity of reactive power and converter station voltages in the converter station according to a reactive power compensation capacity in the converter station; and 3, according to a voltage level and asensitivity index of the current converter station, determining a removal amount of the reactive power compensation device in the converter station. In the invention, excess reactive power compensation provided by the reactive power compensation device after the direct-current locking is considered, and after a direct current system is locked, an in-station reactive power compensation device is used for providing voltage support for an alternating current system so that a dynamic voltage support capability of the alternating current system is improved.
