The invention relates to a method in which a static reactive power compensator inhibits the transient voltage fluctuation of a converter station; by the mutual cooperation of a DC control system and a static reactive power compensator control system, the transient voltage fluctuation which is caused by the input or removal of reactive power equipment in the converter station is inhibited; the DCcontrol system gives out a control command so as to input/remove the reactive power equipment, simultaneously, the control command is conveyed to the controller of the static reactive power compensator which temporarily reduces/increases the TCR triggering angle reference value of the static reactive power compensator in an input/removal instant of the reactive power equipment, and increases/decreases the consumption of the static reactive power compensator to the reactive power so as to limit the change rate of dynamic AC voltage. The TCR triggering angle instantaneous variable is a fixed value; when the control of the controller of the static reactive power compensator leads the instantaneous variable which is output by the TCR triggering angle to reach the fixed value, the instantaneous angle of the TCR triggering angle can be lowered back to 0 from the fixed value within the following time; in the process, the self closed-loop control of the static reactive power compensator also plays a regulating role simultaneously.
